Hi, my name is Kevin Slates, Clinical Associate Professor in the Department of Applied Science at Indiana University. Today's instructional videos going to be on the topic of respiratory protection. The standard number for respiratory protection can be found at 29 CFR 19.13410. It's important to note that respiratory protection is a form of personal protective equipment. Permissible practice requires the employer to consider engineering the hazard out before selecting respiratory protection. As you may know, we have three different options in terms of managing or controlling hazards. Engineering controls, personal protective equipment, and administrative controls. Today's presentation is going to focus on the use of respiratory protection and discuss some of the requirements of the standard. Our learning objectives are going to primarily focus on requirements of those just standard identified two different types of respiratory protection and discuss qualitative and quantitative fit testing. For most respirators, you have basic components. You have exhalation valves and inhalations vow. And you'll see there's a section here for the respirator where you're able to assemble, disassemble the respirator with regard to cartridges, This is an example of a half mass tight-fitting respirator. We have another example here of a full mass tight-fitting respirator with characters as well. Notice the exhalation installation bow on the respiratory protection. And again, this is a form of air purifying respiratory protection. Another type or rest for respirator would be an S CVA and it's air supply. It supplies air to the user. It's important to make sure that the employee has a tight seal between that individual and the contaminant. And osha standard requires employers to conduct both qualitative and quantitative fit testing. Qualitative fit testing is a procedure that's used based on Piot, pass-fail older threshold. A user is exposed to a specific contaminant or an agent. Typically bit tricks are iso enamel, and if the employee is able to smell the contaminant through the respirator, typically that's considered a failure. It's not it doesn't pass because the employee can smell the contaminant to the respirator and that's an indication that it's not a good seal. There's another type of fit testing that employers typically use its quantitative fit testing. Quantitative fit testing gives the employer a numerical value in terms of measuring the content inside the respirator. And if that value is to have, essentially that means that the contaminant is entering the respirator and employees not getting tight seal. So again, you have two different times that fit testing procedures, both qualitative and quantitative. One uses older threshold and other uses a numerical value to determine whether or not the users getting a good seal. Other requirements of the osha standard for a rector protection include initial monitoring procedures for the use of selection of respiratory protection, medical exam, as I mentioned previously, fit testing procedures for conducting a user CEO check, and also procedures for the assembly and disassembly of respiratory protection. For additional information on requirements for respiratory protection, please review the osha standard 29 CFR 1910134

Hi, my name is Dr. Kevin Slates clinical assistant professor in the Department of Applied Science at Indiana University. Today we're going to discuss air sampling for gases, vapors. Subject matter we're going to cover is going to be focused on industrial hygiene principles, concepts, and techniques. Industrial hygiene is defined as a recognition, evaluation, and control of physical, chemical, and biological stressors in the environment. So we have here today we have different types of technical equipment that's used to sample for air contaminants. Examples of air contaminants would include exposure to formaldehyde, carbon monoxide, carbon dioxide, acetone benzene. Exposure to us best IS lead, cadmium, manganese, and similar heavy metals. As industrial Janice, our job is to quantify exposure to determine how much is too much. Our exposures is generally based on the dose-response curve for non-carcinogens. There's a linear relationship to the concentration of the contaminant and the overall health effect. For example, when you're dealing with concentrations, you may see no observable effect based on exposure to a contaminant or substance. An example of that would be one. But if you increase the concentration, even water can be toxic. But in terms of gases, vapors, particulates, we want to quantify how much is too much. And there compared to establish permissible exposure limits, historically, osha permissible exposure limits were adapted from existing exposure limits from a CGI age ACTH as American Conference of Governmental Industrial Huygens. So historically, osha adopted ACTH TLB from 1968. Examples of exposure limits include short term exposure or step 8-hour time-weighted average sea level, an action level. When you deal with conducting air monitoring for contaminants, you should be aware of specific units of measurements and conversions. Example of that would be parts per million. Parts per million is typically used for measuring concentrations of gases and vapors. Milligrams per cubic meter. Wheel graphs per cubic liters, typically reserved for measuring concentrations Of particulate in the environment. An example that would be totaled us manganese, lead welding fumes, mold spores. And it isn't too that with your technical equipment, there are some capabilities or even limitations with the technical equipment that you should be aware of as well. And the main objective of air sampling is to capture the contaminant from the environment and determine concentrations of contaminants when air sampling, you have three different types of error sampling methodology. The first would be active sampling using SKScene pump, for example. Now that would be grab sampling example that we'll be using a handheld drag or to capture the contaminant. On the third type of sampling would be passive sampling. Example that we'd be using field badge to capture contaminant on or to monitor levels of radiation that most people are familiar with. The types of badges that healthcare professionals, we're working with radiological hazards or have read a lot of exposure for additional information on some of the concepts and principles and techniques in terms of air sampling. Go to www.uci.gov or visit the website and review ocean technical manual on conducting inspections and using technical equipment will go to o should website specifically for chemical sampling information. That concludes our lecture on sampling for gases, vapors and for tickets. Hi. Today we are going to discuss technical equipment in instrumentation to conduct air sampling or conducting air sampling. We're really focusing on different types of gases, vapors or particulars that may be present in the environment and make an attempt to quantify and determine how much is too much. Once a lab reports back that amount of contaminant in the environment, we will compare that concentration to establish permissible exposure limits. Before we get into setting up a sampling training, we need to discuss the major parts of a sampling training. But three major parts to a sampling train. The first or calibrator, and we have three different calibrate, yours today to use as an example. We have our, but we'll meter and we have our dry cow. Well, we have one of the older methods of calibrating, which is 1000 milliliter, inverted your rent. So our calibrator is I used to ensure the technical equipment is functioning properly. And with our calibrator, each specific sampling pump will be calibrated at a specific flow rate prior to sampling and after sampling. And again, it's always important to make sure that you pre and post calibrate your technical equipment accordingly. And as I mentioned earlier, you have year Wholeness method of calibration, which is using a inverted Bureau red and Bible soap solution. So essentially you would have your tag on to be tied to this portion of the inverted beer, red. And you'll have your bubble solution and you will have your sampling pump connected to the inverted bureaucrat. And a sampling pump is calibrated at a specific flow rate may have its set. And you'll see here this is called a rotameter. And you'll see your flow adjustment section here. So you may set your flow adjustment for three liters per minute. And generally speaking, for particulate or to set our pump on half flow, you'll turn it clockwise. And there's a screw at the very top of this Casey that you access and you'll take a screwdriver and turning clockwise for particulate, Matthew wanted to, cetera, SKScene pump for gases and vapors. You access this same screw attorney counterclockwise. So again, you have your display indicating minutes and you have your full adjustment screw here. And then you have what we carl here a rotameter indicating the flow. And you'll connect us Casey pump to your tagline, to your inverted pure wrecked. And once the sampling pump is turned on, you should have a bubble generated of the cylinder at or no flow rate. If this Casey palm is pre calibrated or set for two liters per minute. You could have a stopwatch and time the migration of the bubble from the lower portion of the inverted veer it to the top. And again, this is 11000 milliliter direct or one leader, your'e. And this was one of the earliest methods calibrating SKScene pumps before the technology was invented to drag out a bubble need. Okay, we have a different piece of equipment here and this is the bubble meter and this is a book calibrator. They have a similar equipment on a market that would be classified as a bubble meter. And in what type of calibrator would be yellow, brighter. And it functions based on the same principles in terms of having lubricate is cylinder here and you have your bubble solution inside the cylinder and you have a button here and that you'll use to initiate the migration of the bubble going up the cylinder. And the distance has been measured here. And you'll set your SKScene pump to a known flow rate. And again, to determine the flow rate for specific contaminant, you should go to the oceans chemical sampling guide or use the osha tech Manual. And again, go to www.osha.gov and do a search. For chemical sampling information site. And as she give you relevant information in terms of exposure limits, sampling methodology, different types of technical equipment or analytical methods to analyze the contended. So we have a bubble meter here and we have the Cadillac version of a calibrator. And essentially what we have here, we have the dry cow. They call it a dry cow for reason, no bubble solution, inaccurate member as an inspector for osha having to pre calibrated tin pumps before an inspection or survey. The amount of time that it would take you to actually get this bubble here to migrate from the bottom to the top of the cell. And it, and it's not unusual for you to, to take ten or 15 minutes to pretty calibrate in SKScene pump. This is a US Casey pump here in the past, the bubble meter and S Casey pump. And this is a tip. If you want to save time and to be more efficient, it's always best to increase your flow rate of us, Casey, to increase the rate of migration so will lubricate at a faster rate. So it's just a tip from an osha inspector. So you said, David, save a lot of time if you increase increase the flow rate. So you'll see her rotameter here move forward from one liter per minute, two liter per minute, 23, even four. And on the display of your calibrated, you'll see the numbers indicated in CCS as well. And that's a unit of measurement that we use when we're calibrating our SBIC pumps, you're able to look at the flow rate. And again, the flow rate is based on established either whole Chennai OS sampling methodology. And you have your drag out here. And I mentioned it may take five or ten minutes using the bubble meter. It could be a book, could be a calibrator, calibrate him. But if you use the dry cow and 2-3 minutes, you could set the flow rate accordingly using the drought counting, common drag, half-full reason there's no aqueous solution or no bulb solution involved when you're setting up your calibration, which is fairly efficient, well, turn this on here and you should see the display lit up here. And there's a button that you'll push here to actuated. And any time that you push this button, it's going to cycle the dry cow. There's a cylinder inside this. They call it a dry cow, obviously because there's no solution. But it's electronic piston device inside this dry cow that takes a known volume of air and calibrates it at a specific rate. So it's very efficient in terms of pre and post calibration. Again, this is one part of our sampling. Trying discuss, calibrate your. Now we're going to move into the second part of our sampling train, and that would be the SKA see palm with us. Casey As I mentioned earlier, you display your displays nunnery minutes sample, and again, an eight hour tabloid error. It is extremely important when you're dealing with permissible exposure limits. So essentially the pump will be placed on an individual for an eight hour time period and taken off individual. And we've seen that it has a cliff here. This cliff or device will be placed on an employee's side here. And again, it's always best to introduce yourself. Hi, my name is Kevin. Them with osha conducts sampling honest contaminant. Normally, most state employees will will agree to where the sampling pump, but there may be situation where you have to place two pumps on it. And depending on the number of contaminants that you're monitoring for. So it could be uncomfortable. Acker, remember one situation where I was going in and heavy manufacturing facility conducting monitoring for heavy metals. And there was a female, she was maybe 54, and she was warning sweatpants. So you always have to be prepared for these types of scenarios. So I had a an extra belt with me. So we actually place them built around individual. What she said was built not very comfortable or sorry, we'll we'll see if the elastic is strong enough to hold up the, the sweatpants because these pumps can range anywhere between two pounds, five pounds. Who's so she was actually supposed to wear two pumps at the same time. So when we place one pump to the right, another pump to the left, or slip past dropped or an age. And I was kind of a Opera moment there. But she did Go ahead. It's area will give me the belt. So she tried it without the bell. And as you try it with the bill and sweatpants, needless to say, actually did fall. It can be uncomfortable with employees through animation that you place these pumps on employee in a way where it's not very invasive and doesn't interfere with their job or task. But back to the function of this case, EPA. You have your flow adjustment screw here and you flow adjustment screw is going to increase or decrease the flow rate. You have an indicator the flow rate here called the rotameter. And this rotameter ranges anywhere between one liter per minute and about six. Latest finish of ABC to display here on SAC. Or we're going to target Nasir. You're actually able to see it running always best. Have a screwdriver here or long fingernails to actually pump right here. There's going to be, so Sasha SKScene, draw a known volume of air based on sampling methodology through the pump, and the contaminant is going to be captured on that. And what we're doing here, we're setting up our sampling train for pertain to this And we mentioned there are three parts to a sampling trained first as a calibrated. The second is, the third is the Typhaon to boom and media. There are two major types of media that industrial hygiene safety professionals were utilized when conducting sampling for gases and vapors. Gic, we're generalizing in terms of the different types. But you have organic solidarity is a useful gas. Papers about a high acetone methylene chloride generally use organic salt into it. And solving tubes here that we'll use and essentially with organic solvent will break. They enslave each to haul for loud airflow can tab to be captured on immediate inside the salt. But for particulate you'll have to set and we have two different types of constraints. Have PVC came, the C stands for polyvinyl chloride or sales Esther to different types of filters. And typically particulate are captured on these filters instead into the land for now, since we have poly Bonnie, polyvinyl chloride to set attached to it, the set folder. And then to that we're going to set up our sampling training for particular setup. But staff like tray, you'll have to attach a calibrator to tag onto game. We're going to use the multimeter. I think it's more interesting to use the global mu that we're able to see the bubble migrate up to some unknown rate. So again, three major parts to a sampling. Trying to turn this panel, we've got Gary, SK, c pop, and Assad you should see to display indicating minutes. We'll get our calibrator. And calibrate. Here is actually a bubble meter and it's set to unknown flow rate. You can adjust the flow rate here on this case, see Pub, we've gotta taiga 2B. And we have our VGA or three major forms calibrator pump tied onto the new media. If you combine these three parts, this is what we call our sampling Trent. And above all, is generated by pushing, pushing this button here and publish to migrate up to indicate a specific flow rate for additional information. Sampling methodologies to determine the flow rate, type in media used, and amount of volume of air required for sampling. You should always review the osha technical manual for sampling procedures. You should also review what kinda low sampling information website and that you found by doing this sort of time pushes website www. That osha adaptive

Hi, my name is Kevin Slates, Clinical Associate Professor in Department of plot how science at Indiana University. The purpose of today's instructional videos summarize key points related to noise and hearing conservation. For additional requirements for noise hearing conservation, please review though she's standard 29 CFR 19.9510. I encourage you to review the learning objectives, priority, viewing the video, and also respond to review questions at the end. Today's presentation is going to cover requirements of the osha standard for noise hearing conservation. We will also discuss instruments used to measure and evaluate noise. Finally, we're going to discuss how sound is generated and discuss major parts of the year. Typically, sound is generated by evaporating object. The evaporating object causes the air molecules to compress and refract. This movement causes kinetic energy, and this energy is gotta be funneled into the ear canal. Ear canal is going to funnel that energy. I'm not sure if you could see it here. Our technical support considerably, and this is a cross-section of the ear, but essentially the kinetic energy or the air molecules are going to funnel into the ear canal, that air canal, it's going to transmit that kinetic energy to the fluid field tympanic membrane. That tympanic membrane is going to evaporate, causing the malleus, the incus, the stapes to move. And once the Mao, as a thesis statement, starts to evaporator move, that energy has been transmitted the cochlea. The cochlea is what we call the sensory organ of the year. And lastly, that energy source is going to be transmitted from the fluid-filled cochlea to the auditory nerve. And auditory nerve is going to send electrical impulses to the brain, so that energy can be interpreted as an audible form of sound. So now that we've discussed some of the physics associated with how sound is generated and discuss the major parts of the ear. Wanted to discuss some of the requirements of the standard. The standard has identified two specific exposure limits to be determined to much anything above the limits employees, they're considered to be at risk. The first is a permissible exposure limit or the pill. The pale is based on a specific dose or a specific amount of sound over a specific duration. Typically that's eight hours. So the pale is 90 dBs prayed hours. Anything more than that, sit or too much will also have the actual limit. Action limit is 85 dBs for an eight hour time period. You have two tables and the noise standard, g 16 and g 16 a that also identify, allow exposures over a specific time period. But it's important to note in both of the table g 1616 a, you do have the permissible exposure lemma, which is 90 db for eight hours. And action limit Which is 85 dB for an eight hour time period. The standard requires employers to engineer that noise out anytime employees are exposed to 90 db or greater for an eight hour time period. However, if employees are exposed above 85 dB, employers are require to institute a hearing conservation program. That hearing conservation program is going to consist of employer providing employees with Heron protection standards Pacific specifically require three different types of parent protection. It also requires auto Metric testing. The metric testing is done to determine whether or not an employee in fact has noise induced hearing loss. The audio metric technician or the audiologists will determine whether or not a standard threshold shift has occurred or standard threshold shift is defined as ten dB or more shift either year at 23, at 1000 hertz. And if the employee is determined to have noise induced hearing loss or ten dB shifted to three or 4 thousand hertz, that IS considered an ulcer reportable. We also have three different instruments here to show you that are used to evaluate noise exposure. First is the sound level meter. For most sound level meters, they should be set at a scale. A scale is a scale of measurement. There are two other scales. Be scalar, c scale. A scale is sensitive to how the human ear perceives sound. And typically most sound level meters was sent to a scale and slow response. It's important to note that anytime that to use technical equipment specifically for the evaluation of noise, it should be pre and post calibrate. It. We have our calibrator air, and it's set at 1000 hertz at a 114 db. So again, any instrument that you use, you require to pre calibrated at a known rate and post calibrate. And compare the calibration rates to see if there's any difference between the pre and post calibration. And again, it sound level meter is used to determine instantaneous sound levels at a specific point. Now we have those SAMR to dosimeter. I'm not sure if you could zoom in here. Technical support, I think he's doing that. But the dosimeter is a personal monitor use to integrate noise or sound or an eight hour tab for it. At the end of the word shift, the employee will take the dosimeter off and a safety professional, industrial hygienists will collect that DO software instrument. And once you know the dos, you're able to use a mathematical calculation to convert that Dove to an eight hour time weight average for a noise exposure. And again, you're going to compare your dose or your 8-hour time-weighted average and determine whether or not it's above or below permissible exposure limit for the action limits for noise. Lastly, we have an octave band analyzer. And octave band analyzer is what I'll call the Cadillac version. Sound level meters does everything a sound level meter does, except it determines the frequency the sound is being emitted. It typically octave band analyzer just set to see scale. It does have a scale. Bees go to loop and she'll send it to C scale. C scales typically what we use to measure environmental noise. And once you determine the frequency that the sound is being emitted, it, you're better able to select appropriate engineering controls to manage those sound levels. So we've covered specific instruments used to measure and evaluate noise exposure. We've discussed some of the requirements for that noise standard. And we also discuss requirements for hearing conservation program. Again, there's much more to noisy hearing conservation. In this short instructional video, I want to encourage you to review the noise standard, 29 CFR 19.9510 for additional information on noise and hearing conservation
Description of the video:
Hi, my name is Dr. Kevin Slates, Clinical Assistant Professor of Science and Industry ladder. Today we're going to discuss noise and hearing conservation. Did you hear me? I said today we're going to discuss noise and hearing conservation. Alright, F3 objectives. Today I'm going to be discuss the physics of sound. The second objective is going to be discuss the major part of the year. The third objective is going to be identify specific regulations of standard as they relate to noise and hearing conservation in terms of how sound is generated, its basic physics. So we're going to discuss some of the physics on how sound is generated. Generally speaking, there's a vibrating object. It could be a bell, could be your vocal chords. And a vibrating object moves, which causes positive and negative fluctuations in atmospheric pressure. So if you can picture these air molecules, the compression and refraction of the air molecules upon each other propagated through the air and eventually going directly into the ear canal. Now this provocation of air molecules is essentially a form of kinetic energy. And this energy is eventually directed into the ear canal. We have three major sections of the outer, middle and inner. And when we're discussing the air, we have three major organelles within the year that's responsible for Sam. We have the tympanic membrane. We have the three smallest bones in the by the malleus, the incus, the state these. And then we have the cochlea, which is responsible for transmitting the energy received to the auditory nerve. So essentially what we have here for the transformation of the energy when the vibrating object moves the air molecules, we have a form of kinetic energy. Then that kinetic energy is transferred into the ear canal, causing the tympanic membrane, which has fluid field to evaporate and move, which is a form of hydraulic energy. The energy is then transmitted to the three smallest bones in the by and serves as a form of mechanical energy. And that mechanical energy is further transmitted to the cochlea sound. The cope, when you have hair-like cilia, are receptors that will receive that energy source. And over extended period of time, due to overexposure to noise, the hair-like cilia or receptors will lay down. Typically use this description and class that most people can relate to is essentially or similar to walking through your front lawn to get to your mailbox. Over extended period of time, the blades of grass will lay down and eventually you will have a path, a clear path to that mailbox. And that's essentially what happens in auditory nerve. This lamb with the hair-like cilia overexposure to noise. The cilia receptors in the cochlea are damaged and family, you'll have energy transmitted from the cochlea to the auditory nerve, and the brain interprets that energy source as sound. Final learning objective today will focus on regulations and standards pertaining to noise inherent conservation. Regulation that you should be concerned with dealing with noise in hearing conservation is 29 CFR coded Federal Register 19.9510 to specific requirements under this standard permissible exposure limit to which employees should be at or below during an eight hour shift, and that's 90 db. And there's another regulation that requires employees to keep employee exposure between 85 dB and 90 dB. And that's defined as the action level. Anything above those two levels is considered an overexposure. Individuals exposed to 85 dB or hire should be included in the hearing conservation program. The major elements of a hearing conservation program include initial monitoring, hearing protection for the employees, training. Finally, audio metric testing. Now for the MISP exposure limit, if employees are exposed to 90 dB over an eight hour time period. Engineering controls should be considered as the first line of defense in terms of hearing conservation that we want to focus on what we call a standard threshold shift. That's an indicator that there may be some damage to the hearing due to overexposure to noise. And a standard threshold shift is defined as ten dB shift in hearing relative to the baseline at 234 thousand hertz. Additional information on regulations and standards as they relate to noise inherent conservation. Please review the standard 29 CFR 19.9510. That concludes our lecture on noise inherent conservation. Hi. Today we're going to discuss instrumentation to conduct noise monitor. There are three major devices that are used to conduct noise bond. You have your audio dosimeter, you have your sound level meter, and you have your octave band analyzer. And today we're going to discuss some of the capabilities or even limitations of the technical equipment that we have here. I want to start out with our dosimeter. And we have two different types of saboteurs. Here we have the AMA tick mark three audio, dosimeter and audio to submitters devised. It integrates noise over an extended period of time to indicate the overall exposure. Typically, noise monitoring is done based on an eight hour time way, dab. The instrument will indicate the exposure level in a form of a dose and adults will have to be converted to an eight hour time. We damage. This is an older instrument here with the AMA tech. More free audio to assemblers. We have a quest DO. And this is the Cadillac version of submitters. It will do everything for you. Self calibrate at a known frequency. You're able to download some of the data into specific charts and graphs to show peaks and troughs and number of cycles per second. An overall visual representation of individuals exposure over an extended period of time. But this is the Cadillac version, the assemblers, it will self calibrate again. And there are a couple of functions that you need to be aware of with your audio to assemblers are audio de assemblers are going to be set for two thresholds and 8090 threshold. And sampling with that means is the issue is that it's throttle up, start collecting data at that specific threshold. For example, for our hearing, conservation action level is 85 dB. For the permissible exposure limit, the pale is at 90 db. So this instrument is going to start integrating noise. It, those two thresholds. Noise is measured on a scale, and there are two or three different types of scales, a scale, B scale, and C-scale. For our purposes, we're going to start our instruments to a scale because it's similar to how the ear perceives sound. And you see, I have the instrument turned on here. And you'll see several displays in this instrument. And you can cycle through the dosimeter and you'll see settings such as time. So an employee will wear this instrument over an extended period of time, typically eight hours. And as the instrument will be taking taken all for the individual at the end of the work shift. And you're able to read the dose or percent of exposure for that individual. And we're going to cycle through it here. So you've able to observe some of the settings on this device. Here, stand by. For example, if the employee Has to go on break. You put it on standby, possibly lunch or if there's a situation maybe in production that summer has to be removed and you still want to maintain the time that has been recorded during network shift. You just put it on standby, cycled through it again here. This is one dose, which is the 18 threshold, and then have a blinking DOS here, and that's the 90 threshold. So essentially the assembler is going to measure noise for two different standards. A permissible exposure limit, which is 90 dB over 8-hour time-weighted average, and 85 dB, which is the action level. And as we mentioned earlier, anything about 90 db in terms of exposure requires an employer to implement engineering controls. And again, an exposure level of 85 dB to 90 db employers required to implement a hearing conservation program. We discuss the major elements of hearing conservation program earlier in our lecture. Again, the instruments in terms of capabilities with limitations, have to be aware that the instruments that were using our type two instruments. So we'll just type two estimates me, it means it has a margin of error of plus or minus two dB. So in either direction. So for compliance purposes, if you have an exposure of 85 dB, generally speaking, you need to be at 87 or higher to justify an osha citation. So essentially, we're giving the employee the benefit of adapt in terms of the limitations of technical equipment that we have. We're going to cycle through this again here and get SL Am. So limb stands for sound level meter, and you're able to use this as a sound level meter. If you don't have here a sound level meter here as well, there's an attachment that you'll use and extend the microphone out. But it's important to remember what the technical equipment that we have here and you have to pre and post pre and post calibrates, excuse me, all of your technical equipment to ensure those functioning properly. So before the work shift or when you're preparing for the surveyor inspection, you should create, calibrate your technical equipment, and afterwards post Calvary, and we'll run it going to a demonstration of how to calibrate your equipment. And speaking of calibration, we have acoustical calibrator. And his calibrator, it's going to emit a sound frequency, unknown sound frequency. And hopefully if we pre and post calibrate at a known frequency and the numbers of consistent, that's an indication or technical equipment is functioning properly. So we have the instruments set at 94 dB So the calibrate is emitting a sound that unknown frequency, that dosimeter is actually recording the sound being admitted from the calibrated. So before and after the use of the type of equipment. Again, you will pre and post calibrate and for some reason if you're breathing is out, for example, RED about 94. But if we were at 94.7, you may want to adjust the calibrator here to accurately reflect 94 dB. For example, if it was 93, and I want to move it up so you can take a screwdriver and adjust it here. Ok, one Stan Schmidt is calibrated, will secure the cover to make sure that the employees don't tamper with the instrumentation. Of course, they wouldn't do that, but you're going to be at a place for eight hours. You wanna make sure that the technical equipment is secured. She would feel placed this dosimeter on the side of an employee. Maybe they have a belt, you flip another belt. If they don't have a belt, maybe somewhere along their way, still place the dosimeter and it's portable, it's pocket-size, it's not very invasive. They won't interfere with the job or task that the employee is doing. And you have your cord that runs directly to your microphone. And the microphone various placed around the hearing zone of the employee, typically around the collar, somewhere around the neck to make sure that the core doesn't interfere with employ. You may have to run it under a shirt or up the back of an employee and around their hearings on possibly like this, whichever's can be in terms of best practices, anytime that you're using any monitor, your equipment, it could be a dosimeter or SK c pop. It is always best to introduce yourself to the employee. You just don't want to run upon employee and revenues are a wasteland and slap ten pound as Casey pump on individual and saying where you want to introduce yourself and possibly discuss why you're conducting this monitor. And I asked them would they participate and they kind of go from there. Again, we mentioned our Cadillac version. This is SS Audio dosimeter. In terms of calibrating, it will self calibrate. And there's a function here and you'll see the calibration button. And once you use this button, it will calibrate to unknown frequency. And if the known frequency is consistent with what you see on the screen, you can actually adjusted so actively reflect no calibration DB or frequency. And again, this does come with a cover, so you're able to secure it as well. And we're going to discuss A direct reading instrument. It's not going to integrate sound over extended period of time like that assembler that's going to give you a snapshot or direct reading of the exposure at that time. And it's a handheld instrument. And there are several functions that you should be aware of when using this instrument. You'll see it's set to a scale. And we mentioned earlier the three scales, a scale, B scale. And see scale a scale is typically use when you're monitoring for a noise exposure for humans. This is similar to how our ear perceives sound, C-scale in a scale that's used when you're using the octave band analyzer to look for engineering controls or environmental noise. Let's say we have two different responses. You have fast and you have slow response. And you'll adjust fast or slow response based on the type of noise being admitted, if it's continuous or if it's intermittent. So you've got to fast or slow response. So or continuous knowledge, we're going to place it on a slow response. And they have a specific range here. So based on the sound being emitted from the process of technical equipment or whatever your monetary, you'll adjust the range accordingly. So again, should we set to a scale slow response to a specific range? That's the sound being admitted at sea. For calibration purposes, we do have calibration button that will calibrate this instrument. And we do have a handheld calibrator that's going to emit a sound at a specific frequency. Let's say we've got to adjust it here. And this calibrator is calibrated at a 114 dB, that hurts you that. Okay, so with a sound level meter will use this acoustical calibrator. And hopefully our instrumentation should accurately reflect the dB range be emitted from the calibrated, sorry, calibrator is emitting a sound at a 114 db at 1000 hertz. And if our fishermen is working, are functioning properly, you should have a similar numerical value on the display. Again, with that sound level meter, it's going to give me an instantaneous reading of the sound. So useful for spot checking the sound level with me, maybe too low enough where it doesn't mark monitoring. So you may not have to use the audio dosimeter if sound levels are below 85 dB, or Alasdair Schmitt that we hackers and out-of-band. And we mentioned the quest is the Cadillac version of know somebody who is. This is the Cadillac version of sound level meters. It's maybe a sound level meter. What was interesting about this device is it does everything the sound level meter does. But more again, similar functions. You will place it on slow response a scale. However, you're able to look at the frequencies this sounds are being admitted at. For example, if you do have high levels of sound and the sound needs to be control, engineering controls example that would be selecting the proper building material or acoustical material that you may use one enclosure or used to either reflect or absorb some of the energy or sound. These materials have what they call sound absorption coefficients. And sound absorption coefficient are typically based up on the frequency that the sound is being admitted. So for example, if you have press machine that is stamping out metal parts for household appliances, you can use this octave band analyzer to see what frequencies the sound is being admitted it, and then correlate that with the proper engineering control to reduce sound levels. For additional information regarding noise and air conservation, you should look at the standards way. Now, CFR 19.9510. You should also review the osha attentional manual on how to conduct inspections dealing with noise. More specific requirements for technical equipment

Hi, my name is Dr. Slates. I'm Clinical Assistant Professor in Department applied science and faculty member in industrial hygiene and safety science program. Today we're going to discuss occupational exposure limits and sampling and analysis for gases, vapors, and particulate. Before we go into the specifics in terms of the capabilities and limitations of our technical equipment. It may be best to get a better idea of regulations, standards as they relate to exposure limits. Osha was established in 1970. When osha was established, they haven't developed any occupational exposure limits. So what did they do? They had to adapt. Existing exposure limits from other agencies concerned with health hazards are exposures. So in 1968, the occupational TLV is from AIG, American industrial hygiene Association, were adapted by osha 0000000001968 a CGI TVs were adopted in 1971. We are adopted in 1970. Osha establish specific limits. Anything above permissible exposure limit the ceiling while the steel would be too much. And when we consider noncompliance, specifically, the permissible exposure lemma is based on an eight-hour tau weighed average of exposure that an employer and individual can be exposed to without adverse health effects from the stale short term exposure as a 50 minute exposure limit that the employee may be exposed to without adverse health effects. Anything above that limit per 15 minutes will be considered too much math. And plants from the ceiling limit. The ceiling limit is an instantaneous exposure limit set. That employee may not be exposed above at any point during their work shift. And there are some concerns in terms of using the 1968 a CGI age TLV limits, they haven't been updated since 1968 in terms of OCI of permissible exposure limits, stills or ceilings. So osha limits are legally enforceable. Acg age updated exposure limits or not. Generally speaking, there's a one-to-two relationship between osha exposure limits or ACG TLV limits, meaning if an osha exposure limit is set at 50 parts per million, the more updated exposure limit from a CGI age would be 25 parts per million. Another agency, not ours, the National Institute of Occupational Safety and Health sets or creates exposure limits annually as well. Now, I asked, does not have any enforcement capability. However, they do produce recommended exposure limits. Oh.

Hello My name is Jose Quiroz a first-year master's student, at Indiana university I'm studying safety management today are going to be doing a training on electrical safety. How to begin the purpose. This trees educate viewers on the recommendations associated with electrical safety. Lockout taggers begin by our learning objectives somewhere. First of all, we're going to be defining where electricity is less than ten components associated with electrical safety. Discuss they can tips when working around. Interesting. Next we're gonna discuss in general industry standard associated with classical safety. Discuss lockout tiger procedures discussed. Two types of electrical current can start by defining electricity. It's a source of energy to power devices, or current is measured by amps amperes. This term used to describe electrical flow de, energize its electrical devices. They have that are disconnected from all energy sources, either direct connect for storing electrical energy. Now, a ground fault circuit interrupters provides additional protection from sharks by showing up to the appointment. When you change, an electron scientist says grounding supervisors, they had between electricity and water, just electrical potential. Two types of voltage safety is high-voltage, low-voltage. I wanted our electrical systems for a witness operated over 600 bones, long bones, which are electrical systems or equipment on operations at or under 600 words. They are polarized helps reduce the potential for shot with easy identify upwards of a person as a person as much as familiar with the construction and operation of the equipment and hazard identification. Now, a qualified lead per worker is a person into training experiment. If electrical circuits and equipment shows the knowledge to work near energized equipment. Adder Abbas walls. Resistance is the ease with which the electricity flow through material. Two types of electric current are AC and DC. Ac, our power source, a generally supplied by power plants. Ac energy is either distribute by or underground power lags. Dc direct current is direct source power such as your battery on your phone or uninterrupted power supply or standard associated with electrical safety is 1910. So far as this basically is based on the national and international Fire Protection Association, or NFPA 70 ie. What standard says under ofs as electrical equipment shall be free from recognize hazards that therefore can cause serious harm. Physical safety of equipment should be considered by some of the following conditions. Solve safety requirements by mechanical stress to a lowly insulation effect under uses regular wear and tear. Now when identifying disconnecting means, circuit is the disconnecting means is a switch that is used to disconnect the connector of a circuit from the source of electrical current. Label is important and is required to identify the disconnect this switch to the motor to which current is currently connected to. I'll show you see this can even switch is probably labor would start my work in spaces like Whitman or this section solely focused on who is qualified, work on the environment. Hazards must be treated a little differently, such as person ruined garage working on my part made use of equivalent is important for me. Ready and saving operations up. Clear spaces is working. Spacing required by this part may not be used for storage? We're normally exposed like parts for inspected inspects. Its initial employees. Now working on this part should be guarded according to protect me. Okay? Now, life parts requirement. This requirement is to protect any person who may be in the obscenity of electrical equipment against accidental content. So shall the shell guards, guarding against accidental contact by approve cabinets or other means of approved enclosures. Polarity, no brown conductor may be attached to a terminal. Or this might cause really to particularly a ground terminal is grounded device. There's foreground devices only useful purpose of granting. Now, reverse polarity is a condition when the identify circuit conductor is incorrectly. In most cases, installation and grounding are used to prevent injury from electrical wiring. Now our 2's I have had have non metallic cases or Darwin's lady generic 5-gram. Now let me show you how to test. So what I have in my hand is calling G GET ten checks purple. Why checks proper worried and standard 20? Well, you first and of course you have to remove white appliances connected the ground. True. And so you once you connected in Like fleshed out U3 likes. I'll depending on what's wrong with it. Why correctly? Certainly. Lana and if last two were employment here, right up here. This is for the middle one lights up. That means grabs open right here. That actually both these have to be to say hi to reverse and if metal night out and open up. Alright, now let's talk about flex, flexible pores and cables that most frequently by there are flecks forth and kale should be only used for wiring pictures connecting a portable lamps or appliances, elevator cables, wiring of crane or force, and the prevention of transmission of noise or vibrations. Now they should not be used for as a substitute for a fix wiring going through holes in the wall, floor, ceilings, or doorways. Windows should not be attached to the building surface or conceal behind building water flows. Okay, awesome tips. Now safety is number one. So assume our wires or endure energize. Never touch exposed wires for volume or power lines. We're worker outstanding modern parallel I fulfilment quantify the EU's GCF hide. When working on damped conditions like our tiger procedure involves read poems. No training must be involved. Or is it our inspection must be conducted before that tag out and to ensure nursery or say, to work on most important effect. The personnel tax must be durable.

Or if a person says that since victim shaming or remove a tax document, personnel know concerti work was there. Who's done? Now, at the end of the presentation, there are a few review questions that we answer then be submitted to Dr. Kevin slate. Case, late at night, you think

Hello, my name is Arthur Tyrone Davis the third and I'm a second year graduate student in the Safety management program at Indiana University Regardless Today's learning objectives. For a presentation at the end, we'll be able to identify the laoshi jiao, the OSU construction standard number for both personal followers in groundwater systems will become more familiar with the proper specifications for constructing personal followers systems were identify the requirement or construction for real systems. And we'll list and describe the seven major components of a possible personal followers. Just lastly, we'll learn the proper use and maintenance of personal polymerase systems. The ocean construction standard for personal followers systems is to 29 CFR 1926, got 5-0 to part D. The osha standard for groundwater systems is that at 29 CFR 19.0126 b. Now, here are some general osha standards when it comes to the USA to fall protection in the construction industry. In general industry, the construction industry, the amendment just require for the use of crop protection is six feet. For 0 industry, the bending, this is required for the sub-par protection is only for-fee. Okay. Now, as we move along, I want to give you gossamer specifications on gar will systems, okay. Where workers are construction side that are exposed to runnable drops of six feet or more. Also requires that employ our protection in one of these following three ways before work begins. One of the first ways the employer may try protect its employees is by placing our rules around the heart has an area. A second way they may go about doing this. The safety nets are way your employer may go about this is reviled personal followers systems for each employee. If these are now going to use more important facts on godless systems. And many times you need to know that many times the nature and the location of work where they take the form of foreign protection that your employer may use if the employees and chooses to use a girl with a system is so poor that he must comply with this following provision. I want to make sure that the top edge of the talk, it's height of the rails or equivalent Gore arose system components are between 301945 Logging and working level except with conditions weren't otherwise in any other safety criteria are met with a measure that mid Rails screen mesh, any intermediate vertical members are furcula, intermediate structure must be estar, which were the top is in the walking or working level surface where there's no law or other structures at least 21 inches high. Also important to remember that regardless, systems must be capable of withstanding at least 100 pounds of force applied within some edges of the top edge in any direction at any point along the age without positive, the top edge of the Gerhart roads deflect downward to a height less than 39 teaches about the walking or working web. Importantly, note that Rails screen mesh indicating any other immediate neighbors, must be capable of withstanding at least a 150 pounds of force applied in any direction along the mid route or any other member of the grandma system. Now let's go ahead and move on and learn more about the ensuring the proper use in the construction of personal followers systems. It's important to know the possible follow. A system must limit the maximum arresting force to a minimum of 8000 pounds. It must be read in such a way that an employer can either freefall what does 60 OR contact any other level. It's important that the person will follow Rest system bringing up to a complete stop and limit the maximum deceleration distance, 23. A happy. Moreover, it's important that personal follow racism have sufficient strength to withstand talk twice the potential impact energy of a worker falling from a distance of six feet or the F35 does, is permitted by the system, whichever is less. Okay, more general techniques for probably maintaining and using your progress system. One thing is to make sure is you want to remove systems and components for service. A really after your personal reputation system have not been involved in a fall or impact until it's expecting brother. Properly accredited parsing look indeed that house personal progress system. Good for US. Again, very important to make sure that you're inspecting your system before and after each use for damaged in any other possible signs of wear and tear that wood or probably the two hazardous situation or condition or you want to make sure you definitely do not every task progress systems, Garbo system are boys. And you want to make sure that your polymers are read in order to allow free movement of your employees so they not subjecting themselves to any Moreau hazardous condition? The situation due to not being constricted from their space and movement, were trying to perform their work tasks. Now we're going to go ahead and move into the seven major components of personal follow Rest system. And these components go as follows. You have your harness You have your vertical like lot slash layer, you have your attachment location, your connectors, you have your webbing acreages, and you have your horizontal light, blah. Okay. Yeah, we'll just go ahead and give you guys a brief demonstration on how to properly place all your personal follower, our system. The cells are more or less, here's your force. I have your back thought. No, this part right here, you see my fingers from a through G rain. And this is where you attach your layer and go, hey, in. Furthermore, attach your language is location for your anchorage point. And I'll put this on is fairly simple. You see this part right here is where your head is going to go through was kind of like putting on a backpack. Flow the more difficult, but I don't want my flow. Now is very important in your personal follow racism. That's your webbing is made of synthetic fibers. We're gonna make sure all your connections or your connectors are made of Peshawar steel. What am I sure. Any particle like glass or horizontal lifeline or anchors point station tied to or able to withstand the potential impact force of 5 thousand pounds per employee. Now right ears are currently doing tight enough or your chest area, we want to make sure you have a nice firm fit. Okay, we're gonna go ahead and drag it to your local to do on this. Want to make sure you stand a good dinner straight, just the dimensions. You get a nice fit to be sure. Proper fading, so avoiding unwanted hazards. Now as a rule of thumb, you take your two fingers and kind of slot it in between your bot and make sure you have a nice fit. It's very important to make sure not to constrict because you want to be able to freely move and truly working your work area without Eve in causing anymore additional hazards due to too much constriction in not enough free movement. But after you go and you feel like you have a nice game or your harness, grab your way or make sure your hooks a properly functioning things. We want to make sure every time you put this wanted to take this off, will it make sure that you inspect it pre and post ship just for any where axiology may see may warrant a hazardous situation or condition. So go ahead, take your heart rate, this one, you will go here and you will place this one eye at a anchors point or on a vertical line or a horizontal line, blah, blah. Service provider for you, hook up measure other PPE is odd. Once again, make sure you're able to move freely. Make sure you're not too constricted in your personal highs. And then you're free to go and you're free to go and do your work safely. My name is Tyrone Davis, daughter. Once again on a secure, we stood University. This brief presentation, personal followers, system safety and management. This video will follow up with a brief review with a few questions like, you guys have a nice day.

My name is Adam Santos and I'm a second year graduate student safety management program at Indiana University. And this is a podcast video lecture on portable a frame lighter safety review learning objectives carefully before viewing the podcasts video lecture. After viewing the video in detail, the review questions at the end of the presentation. Students, such course participants should email the review questions to course instructor Kay slates at indiana.edu. Remember, most later accidents are the result of careless and improper latter usage. Also remember that nearly all falls reminders can be traced to using them in an unsafe men when a fall occurs, pursuing falls usually gets hurt. Today we'll be focusing on specific portable ladder, which is the a frame. This training video hopes to accomplish three learning objectives. First, we'd like to identify the major hazards associated with portable ladders, specifically the iframe. We'd like to recognize the parts of an iframe ladder and become familiar with requirements of the osha standard 29 CFR 1926 subpart x feature. The latter select, it has the proper duty rating to carry the combined weight of the user and the materials being installed. A lattice duty waiting tells us its maximum weight capacity. There are four categories of duty rate Type 1A, these ladders, heavy duty free, a 100 pounds type when he ladders that are suggested for heavy industrial use. Our second letter is the type one letter. These ladders, heavy-duty weighting of 250 pounds and type one are also for heavy use. Type two letters have a heavy-duty weighting of 225 pound. Tend to ladders are appropriate for medium due to US. Finally, the tag three-letter. These letters have a duty ies of 200 lb times. E. Letters are made for like the type 1A and the type one ladders are only acceptable letters used on a construction site. This is indicated here. As per the duty rate, be sure that the metal steps in round, r grooved or to prevent slipping. Again, look at these grounds. There grooved thereof. There's no to breeds, prevents flip on a very clear steps up key steps in the rungs of the ladder is free from slippery materials. A good way to do that is to kind of agree from your shoes before using letter. Always face a ladder when climbing up or down, use both hands and maintain a secure grip on the rails or rungs, both hands-on real standard of glare Up into the Sun. Never carry heavy or book. He loads up the ladder. Climb up yourself, and then pull up your material with a rope. Climb and stand on the letter with your fee and the center of the wrong hands on the rails towards the center of their own. Do not overreach from a ladder or lean too far to the side. Over-reaching is probably the most common causes of fall from a ladder. A good rule is to always keep your belt buckle inside the rails of the leg. Hands on the rails, belt buckle in-between to real people are generally in-between. These work as far as you can comfortably and safely, and then move the ladder to a new position. Never climb onto a letter from the side from the above top ladder or from another lacquer. Never slide down the ladder. Never used the letters around expose electrical wiring. Metal letters should be marked with tags. And should you similar wording to caution, do not use around electrical equipment on our ladder here, it's in yellow and it says, gosh, I do not use around illegible. If you get sick, dizzy, dizzy or panicky while on the ladder. Do not climb down in a hurry way. Take your time. Drape your arms around the runs, rest your head against the ladder until you feel better, then climb. Now safely income. Let's switch to load. Self-supporting fold-out keyframes must be able to support at least four times the maximum intended low, except extra heavy metal or plastic layers which must be able to sustain 3.3 times the maximum intended load runs. Runs must be parallel level and uniformly spread from about ten to 14 inches, as you see here, runs about approximately 1014 inches apart. Proved clear of any degree other requirements, holdout set Lehrer's most heavy metals spreader or locking device to hold the front and the back sections in an open position, as you see on here. Here's our locking mechanism is on both side. It should be closed out and unlocked position when it eats, the area around the top and bottom of the ladder must be kept clear down here. And again, up here, never use a ladder for any other purpose other than what is designed for. To summarize, make sure your letter can handle. It's intended to make sure you may take three points of contact. Don't the in-degree, always proceed with caution. Make sure your browser functional a clear of any degree or a podcast review questions. Yeah.

Today we will we will be working from the industrial hygiene lab manual. We are going to conduct the lab iron oxide metal fume sampling and evaluation. This lab is conducted by Sean shivers. The equipment we are going to use is the case C p C acts are for universal pump and low-flow adapter. We we will be using the TI gone connective tubing for personal sampling pump. We will also be using the bios dry cow DC like calibrator 500, mLs. We will be using a stopwatch to keep track of the time throughout the entire lab. We will be using 37 MM, 0.8 micron pore size MCF cassettes. And we will be using the industrial hygiene sampling documentation forms for airborne sampling contaminants, and sampling pump calibration, which are forums 13. We will now run through the lab. First, we will assembly the sampling train and allow it to run for five minutes before pre calibrating it, we will take up the knobs on both sides at the MCA to filter and insert that into the KA-SAT holder. We will use another piece of Thai gone tubing to attach the cassette to another dry cow. So one side is attached to the dry cow and one side is attached to the S Casey pump. When attaching the tag on tubing to the dry cow calibrator, we want to make sure to use the outlet. Once the sampling train has been assembled, we will pre calibrate the sampling train, making sure to run the document, run the dry cow, and use the stopwatch to time how long it takes to get from the beginning of a lab till the end of the lab. Once the pre calibrating has been complete, we will mount the sampling train on our partners or on a worker. We want to make sure that we disassemble it from the dry cow so that it can be used to keep track of the sample of the media that is described during the lab. We want to make sure that we attach this on the non-dominant side. This would be worn during an eight hour shift and it would be taken up every time there was a break after the instructor's approval, we will disassemble this from the worker and we will reconnected to the dry cow calibrator so that we can post calibrate, making sure to look at the stopwatch when the lab is complete so we know how long it took to run all the tests. We can turn off the bass, Casey palm and, and record our information. It will be important to fill out forms one and forms three throughout the entire lab. And these are described throughout the manual. And this completes the lab iron oxide metal fume sampling and evaluation

Today we are going to be working from the industrial hygiene laboratory manual. We will conduct a lab acetone integrate a gas and vapor sampling sorbent tubes, the lab is, conducted by Sean Shivers. The equipment we are going to use is the Casey PC acts are for universal pump and low-flow adapter. We will be using tag on to being for the personal sampling pump. And we will be also using a sorbent tube holder. We will be using a dry cow DC life calibrator, 500 ML. We will be using the acetone sorbent tubes as well as the two breaker during this time. And lastly, we will be using the acquit, the industrial hygiene sampling documentation form one and form three. Now we will run through the lab you, the first step we will do is assemble a sovereign tube sampling train and calibrate the low flow pump and adapted high low flow pump with the tube holders. With this sampling media in line, the first thing we will do is turn on the S Casey pump. We will add this warm up for five minutes before taking the pre calibration. After the five minutes have been run, we will adjust the high low flow pump to 1.5 liters per minute shown on the pumps rotameter using the flow adjustment screw located beneath the keypad. After every week we reach 1.5 liters per minute. We will press the start a hold button to cause the pump to pause and hold. We will remove the small brass grew cap on the top of the pump and turn the deep set screw beneath the cap four to five turns counterclockwise. This places the pump in its low flow mode. Once this has been achieved, we will replace the small brass cap. Now that this has been adjusted, we can now turn the pump back on. The next thing we will do is adjust the flow rate for the suburban tube. This is obtained by adjusting the set screw on the tube holder. Light decreases the flow rate and left increases the flow rate. The flow rate for gases and vapors are fifth DCC to 250 cc. We will now use the sorbent tube and break both ends using a tube holder. It is important to wear safety goggles At this time. Using the two breaker, we will break both sides. When inserting the tube into the S4B in tube holder, it is important that the arrow points towards the pump. We will now start the calibration sampling. It is important to use both sorbent tubes, both Taiwan tubings, to attach one to the S Casey pump and one to the dry cow calibrator. It is important to make sure to use the outlet while going through the calibration process. The dry cow, cow greater should be at an airflow of 0.05 liters per minute. We will take four to five readings and make sure to record this information and the average in the form number one and form number three. After we've calibrated, we will assume that one lab partner is the worker. You are going to sample and hang the pump and the sampling train on our partner. It is important to adjust this on the non-dominant side of the worker. This would be worn during a shift. All information obtained during this would be filled out on form one, we would fill out all the worker detailed the sample conditions as we did in earlier lab exercises. Once the instructor comes around and checks off that the placement of the sampling train is correct. It can be removed from your partner to pose. Calibration can now begin. We will reassemble the sampling train with the dry cow calibrator. Four or five readings would be obtained and we could take an average to record and form one. It is important to show calculations, and that completes lab acetone integrated gas and vapor sampling. sorbent tubes.

My name is Sean Shivers. I'm a graduate student in the Safety Management Program in the School of ever here at Indiana University. The purpose of this instructional video is to discuss and demonstrate basic fire prevention methods, strategies. First, we'll start off discussing emergency action plans, followed by fire extinguisher usage. Then we'll end by demonstrating the pastor first. It is very important to know how to reference the standards referencing emergency action plan. Please see osha standard 29 CFR 19.13810 to reference fire extinguisher usage, please see offshore standard 29 CFR 19.15710. It is very important to understand that if an employer has less than ten employees and oral emergency action plan will suffice. However, it is an osha requirement that if an employer has ten or more employees, they have to have written emergency action plan. And there are also two components that are key in understanding and emergency action plan. The first is accountability followed by a designated meeting location also requires that an employer has accountability for all employees on site at all times in the event of an emergency and designated meeting area is required by osha and it must be understood by all employees. Now we'll get into the fire extinguisher standard, will discuss some components of the fire triangle, followed by the common types of fire extinguishers. Again, we'll end by demonstrating the past technique. First, it is very important to understand for these, these three components of fires thing, fire triangle, which are heat, feel, and oxygen. Understanding three, these, these three allows for you to understand how to control the fire, is also important to know that eliminating one of these three components will help you to control and understand. If I now we'll get into some common types of fire extinguishers. You first, which are most commonly used, is your ABC fire extinguisher. So components here, first you have your holes, your inspection tag, your gauge, your pant, then you will actually pull in the event that you have to use it and your trigger, which will squeeze my closing. Your, hence the ABC you ABC distinguisher is used for your trash Norwood in your paper or your combustibles. In other words, it's also used for flammable liquids and your electrical equipment. Again, this is the most commonly use witches are ADC, fire extinguisher Next, we'll discuss the carbon dioxide is the emotion or if CO2 extinction. Please know that you have to use this. The hose on this distinguisher gets very cold. Try not to touch it as it can cause damage to the skin. After your hose, you have your inspection tab pane that you'll pool in the event of a fire and you will squeeze it on you. Triggered again, this is your carbon dioxide extinguisher used for liquids, Greece or solve it. And you can also use this on electrical equipment as well. It is also important to know that there are two other extinguisher types, which are your class D and your class k extinguishers. Your class D is going to be used for your metals and replace k extinguisher specifically for kitchen fires. Again, reference standard 29 CFR 19.15710 to learn more class distinguisher and your class caged English. And finally, we'll end by demonstrating the past Technion. The P in the past technique stands for pole, which will actually pull the pin. The a stands for N. You will aim at the base of the fire. The first S is for squeeze, not just squeezed the trigger. Finally, the last S is sweep, sweep back and forth, motion like this. Again, let's pull the pin and the hose at the base of the fire squeezed the trigger and sweep back and forth in this motion. In the event that you do not put out the fire the first time, simply repeat steps two through four. And that's aiming, squeezing and sweep, hope you learned something new today. Hope you enjoy.
