Advanced Industrial Hygiene
For each of the chemical hazards in the table, complete the following:
Calculate the exposure concentration in mg/m3 for the aerosols.
1. Manganese Fumes: Exposure Concentration in (mg/m3) Mass=5 µg=5/1000 mg=0.005mg
2. Copper Fumes: Exposure Concentration in (mg/m3)
Calculate the exposure in parts per million (ppm) for the vapors.
Discuss where you think errors might have been introduced into the results.
Compare your calculated exposures to one of the occupational exposure limits (OELs) in the table below.
Do any of the calculated exposures exceed the OEL you chose?
Discuss why you chose the OELs you used.
Provide your opinion as to whether the risk associated with each exposure is an acceptable level of risk.
1) For shipping/receiving:
2) For hydraulic press:
3) For metal working line:
4) For robotic welding:
5) For hand welding:
6) For paint booth:
7) QA/QC Laboratory:
8) For final inspection:
Which of the results exceeds the OSHA PEL?
Which of the results exceeds the OSHA action level?
Provide your opinion as to whether the risk associated with each exposure is an acceptable level of risk.
