Hazard Possible Method Occupational Exposure Limits (OEL)
Manganese Fume (Welding) NIOSH 7302 5 mg/m3 (OSHA Ceiling)
Copper Fume (Welding) NIOSH 7302 0.1 mg/m3 (OSHA 8-hour TWA)
Lead Fume (Welding) NIOSH 7302 0.05 mg/m3 (OSHA 8-hour TWA)
1,2,4 trimethylbenzene (Paint) OSHA 1020 25 ppm (ACGIH 8-hour TWA TLV)
Toluene (Paint) OSHA 111 50 ppm (ACGIH 8-hour TWA TLV)
Xylene (Paint) OSHA 1002 100 ppm (OSHA 8-hour TWA)
Metal Working Fluids NIOSH 5524 0.5 mg/m3 (NIOSH 10-hour TWA REL)
Noise (throughout plant) None 90 dBA (OSHA 8-hour TWA)
Choose Lead Fume hazard from the welding area, Toluene hazard from the paint area, and the metal working fluids, and prepare one paragraph for each hazard (three paragraphs in total) answering each of the following questions:
1. Which sampling media will you be using?
2. What flow rate will you use?
3. How will you calibrate the sampling train?
4. Calculate the minimum sampling time you will require to be able to detect concentrations at the OELs listed in the table. Show your work in calculating the sampling times.
5. Will you collect personal or area samples? Explain why.
6. Are there any compounds listed in the method that might interfere with your sample?
7. Are there any special storage or shipment requirements for your samples?
Prepare one paragraph that concludes how you would evaluate noise exposures in the facility. Discuss what type of sampling instrument you would use, how you would perform calibration, whether you would use personal or area samples, and which areas at the facility you would include in the evaluation.
