Title: Risk Assessment and Comparison of Occupational Exposure Limits for Chemical Hazards and Noise in Acme Automotive Parts (AAP)

The sampling results for the chemical hazards you tested for Acme Automotive Parts (AAP) are listed in the following table. The volumes that are listed are what you provided to the laboratory.
Hazard
Analytical Result
Volume (Time)
Manganese Fume
5 µg
30 L (15-minute)
Copper Fume
140 µg
960 L (8-hour)
Lead Fume
40 µg
960 L (8-hour)
1,2,4 trimethylbenzene
5 µg
48 L (8-hour)
Toluene
125 µg
48 L (8-hour)
Xylene
20 µg
48 L (8-hour)
Metal Working Fluids
500 µg
720 L (8-hour)
For each of the chemical hazards in the table, complete the following:   
Calculate the exposure concentration in mg/m3 for the aerosols.
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.
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)
The results for the noise sampling in the following table were recorded from your noise dosimeters. All the samples were collected for the full shift using 90 decibels on the A scale (dBA) as the criterion level and a 5 decibels (dB) exchange rate.
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)
Paint Booth
12 hours
79.5 dBA (Lavg)
QA/QC Laboratory
8 hours
70.0 dBA (Lavg)
Final Inspection
8 hours
73.5 dBA (Lavg)
Answer the following for each of the locations listed above:
Convert the results from dBA to percent. Make sure you show all your work for calculations.
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.
Your assignment must be at least three pages in length, not counting the title or reference pages. Your assignment must use at least two references. One must be gathered from the CSU Online Library; the other may be your textbook. All references and in-text citations must be formatted according to APA Style.
