Case study on paint sampling

Case study on paint sampling

After careful consideration, you choose NIOSH Method 2553 for the sampling. You can access the method by clicking the link below: National Institute for Occupational Safety and Health. (2003). Ketones II: Method 2553. In P. M. Eiler & M. E. Cassinelli (Eds.), NIOSH manual of analytical methods (4th ed.). Retrieved from http://www.cdc.gov/niosh/docs/2003- 154/pdfs/2553.pdf Your pre-sampling and post-sampling pump calibrations using a primary standard are both 0.05 L/min. You collect personal samples on two employees working in the operation.

1. Calculate the sample volumes for each of the samples. The laboratory reports that the front section of Sample 1 contains 5,000 µg of methyl n-amyl ketone and the back section contains 200 µg of methyl n-amyl ketone. The front section of Sample 2 contains 4,000 µg of methyl n-amyl ketone and the back section contains 50 µg of methyl n-amyl ketone. Neither the front nor back sections of the field blank you supplied contain any detectable levels of methyl n-amyl ketone. 1. Calculate the concentrations of the two personal samples in µg/L and mg/m³. 2. Convert the result to ppm (MW for methyl n-amyl ketone = 114.2). 3.

Show all the steps for your calculations.  1. Discuss how the results for the two personal samples compare to the ACGIH TLV. 2. Discuss whether you would recommend comparing the results of your sampling to the OSHA PEL or the ACGIH TLV. Include your rationale for the choice, and explain how you would rationalize your choice to your employer. The case study should be a minimum of three pages in length, and you should cite the NIOSH document using APA style.
