I use hearing protection and eye protection at work ( write about these two)

Your journal entry must be at least 300 words. No references or citations are necessary.

QUESTION 2

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)

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.

HAZARDS Hazard Occupational Exposure Limits (OEL)s

Manganese Fume 5mg/m3 (OSHA Ceiling)

0.1mg/m3 (ACGIH 8-hour TWA) (I)

Copper Fume 0.1 mg/m3 (ACGIH 8-hour TWA)

0.2mg/m3 (ACGIH 8-hour TWA)

Lead Fume 0.05mg/m3 (ACGIH 8-hour TWA)

0.05mg/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 (ACGGIH 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 Online Library; the other may be your textbook. All references and in-text citations must be formatted according to APA Style.
