Unit IV Case Study Corrinne DeMarco Waldorf College Industrial Hygiene 8/24/2017 Unit IV Case Study Unit IV Case Study What is the purpose of the exposure assessment? According to Mr. Sam Sampler, the purpose of the survey was to evaluate personal exposures to select components of commonly used chemicals associated with the ACME printing process. Five samples were taken to assess ink components along with the one sample for ozone. This test is to insure employee heath and safety. Why was the exposure assessment conducted? In my opinion, this exposure assessment was conducted to evaluate exposures to employees working in the facility and also to the ambient atmosphere since VOC’s (Volatile Organic Compounds) are regulated in the amount …show more content…
It is calculated as follows: (concentration of contaminant 1 / OSHA PEL for contaminant 1) + (concentration of contaminant 2 / OSHA PEL for contaminant 2). So, if we look at the personal sample taken from Josh’s workday, we would calculate the n-Propanol ppm of (47/200 = 0.235) + n-Propyl Acetate of (14/200 = .07). Our additive calculation % PEL would equal 23.5 + 7 = 30.5 % (Sampler, S. (2012). Were there any off-normal or unplanned incidents relative to sample collection? The area sample for the ozone was said to be insignificant because the day of the sampling, the lamination process was not in action. This process is one that may produce many vapors, so the readings were not exactly accurated for the “worst case day”. Provide a summary of the recommendations made by Sam “IH” Sampler. Sam Sampler recommended that ACME Printing continue with their air sampling program and also the sharing of all sampling information with the affected employees. A separate study for the area sampling of the laminations process should be done since the laminator was not in operation on the day of the air sampling project. Comment on the thoroughness of the study. Did you feel that the exposure assessment was comprehensive? If not, what additional information would you …show more content…
As Plant director I would have no problem sharing the report information with OSHA, especially when the sample levels are within limits and have been in the past. Although some samples were at 50%, the need for the exposure needs to be kept below that level at all times. When sharing this type of information with employees, especially if sample levels are above the PEL, it is most important to share this information with the employee but also in a manner where they will not become scared or alarmed at what they are being exposed to. I believe that the sharing of this information is part of the required OSHA regulation for
Pollution prevention includes any method which reduces the amount of toxic substances used and which minimizes waste streams. The laboratory uses solvents, reagents, and standards that are frequently toxic. Some of these substances may escape into the atmosphere by evaporation, and some are carried out of the laboratory by the fume hood system. Minimizing the quantity of the substances used and minimizing their exposure to the atmosphere are important in pollution prevention. Containers of samples, standards, solvents, and reagents shall be kept closed if possible.
Explain what happened to the CAP amplitude as voltage applied to the neuron was changed. Be specific with your results and explain why the amplitude was smaller with some voltages and larger with other voltages.
How many ancestors does a node at level n in a binary tree have? Provide justification.
The project is going I am working is almost in the finish stage it is going into the production phase means getting to the live so that the users can able to use the application. After the developing the total code it will go to the testing phase where the testers will check the code is working properly without any errors actually the testers task is to check the code and submit to the developers if they found any errors or mistakes or else they will send the code to the production phase to deploy in the server to check the application.
In the case study “Pirates”, there is a debate of should copyrights been protected or not, or should illegal pirating been allowed? (Brusseau, 2012). One argument states that the copyright should be protected since it is an intellectual property. On the opposite, the argument argues that people who cloning the CDs may purchase the CDs themselves or given the original CDs by someone else, they own this property now, and they can do what they want with it.
Analysis of a set of eighteen samples (six samples at each of the three test levels) collected from dynamically generated test atmospheres at approximately 0.5, 1, and 2 times the OSHA Permissible Exposure Limit (PEL) of 1 ppm.
My original idea was to make a mobile monitoring device that made inferences on a person’s physical behavior, and could give advice on how they could potential lead healthier and happier lives. At the start of my research I was interested in articles about mobile devices such as BeWell[1], which is a smartphone application to monitor and promote wellbeing. It kept track of people’s everyday social, physical, and mental behaviors and provided useful feedback to improve their lives.
This preprocessing step is done before the considered two cases of not split table traffic amounts and the split table traffic amounts. It includes the network topology design as follows:
For my local area, there are no environmental concerns; however, I learned of the detailed information available regarding air quality monitoring – which indicated that the air quality for our location is among the best air quality in the nation. (The state of California leads the nation in several aspects of environmental stewardship.)
The environment and the health of the surrounding population go hand in hand. The Environmental Protection Agency takes on this ever so important mission of protecting them both. The mission statement of the EPA states, “The U.S. Environmental Protection Agency's Office of Small Business Programs is to support the protection of human health and the environment by advocating and advancing the business, regulatory, and environmental compliance concerns of small and socio-economically disadvantaged businesses, and minority academic institutions (US Enviromental Protection Agency, 2010).” The impact of its mission can be defined clearly as it examines the impact of contamination in the air, the water, and the land on human health.
7 Exposure assessment is “the process of measuring or estimating the magnitude, frequency, and duration of human exposure to an agent in the environment, or estimating future exposures for an agent that has not yet been released”
...ove to other shop areas from contaminated hands and footwear. Replace all latex gloves with extended-cuff nitrile gloves. Workers may also use nitrile gloves in addition to every practical task performed in the shop, from surface preparation to application of paints and coatings. A supplied air respirator is the best choice for protecting workers. However, the compressor and other associated equipment must be properly maintained and must deliver sufficient uncontaminated air. A full face air purifying respirator equipped with organic vapor cartridges and N95 pre-filters is the second-best choice. This equipment provides eye full protection. Any respirator must be used within a defined respiratory protection program, including fit testing (for tight fitting styles) and a formal cartridge change-out schedule.
