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

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

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
