Instructions
This assignment has two parts. Both parts will be combined and submitted within the same document. For this assignment, begin by analyzing the items in the table below and then answering the associated questions.
| Hazard | Occupational Exposure Limits (OEL)s |
| Manganese Fume | 5 mg/m3 (OSHA Ceiling ) 0.1 mg/m3 (ACGIH 8-hour TWA (I)) |
| Copper Fume | 0.1 mg/m3 (OSHA 8-hour TWA) 0.2 mg/m3 (ACGIH 8-hour TWA) |
| Lead Fume | 0.05 mg/m3 (OSHA 8-hour TWA) 0.05 mg/m3 (ACGIH 8-hour TWA |
| 1,2,4 trimethylbenzene | OSHA – None Established 25 ppm (ACGIH 8-hour TWA TLV) |
| Toluene | 200 ppm (OSHA 8-hour TWA) 300 ppm (OSHA Ceiling) 20 ppm (ACGIH 8-hour TWA TLV) |
| Xylene | 100 ppm (OSHA 8-hour TWA) 100 ppm (ACGIH 8-hour TWA |
| Metal Working Fluids | OSHA – None Established 0.5 mg/m3 (NIOSH 10-hour TWA REL) |
Part I: For each of the chemical hazards answer the following:
- Compare your calculated exposures in Unit IV to one of the occupational exposure limits (OELs) in the table.
- Does the calculated exposure 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.
Part II: Analyze the table below, and then answer the associated questions.
| Location | Shift Length | Result |
| Shipping/Receiving | 8 hours | 78.3 dBA (Lavg) |
| Hydraulic Press | 12 hours | 93.0 dBA (Lavg) |
| Metal Working Line | 12 hours | 84 dBA (Lavg) |
| Robotic Welding | 12 hours | 80.5 dBA (Lavg) |
| Hand Welding | 12 hours | 81.3 dBA (Lavg) |

| QA/QC Laboratory | 8 hours | 70.0 dBA (Lavg) |
| Final Inspection | 8 hours | 73.5 dBA (Lavg) |
Answer each of the following:
- Which of the results exceed the OSHA PEL?
- Which of the results exceed the OSHA action level?
- Provide your opinion as to whether the risk associated with each exposure is an acceptable level of risk.
