The primary hazards at Acme Automotive Plant have been identified, samples have been
collected, returned with results, and results have been converted to correspond with occupational
exposure limits (OELs). One Aerosols hazard is in excess of the legally enforceable limits set by
Ooccupational Safety and Health Administration (OSHA). It is also higher than the National
Institute of Occupational Safety and Health’s (NIOSH) limit, however it is lower than The
American Conference of Governmental Industrial Hygienists’(ACGIH) recommendation
threshold limit value (TLV). The hazard is Copper fume with a measured result of 0.146mg/m3.
As well, the area noise measurement has been calculated and need to be compared with industry
standards. Both copper fume and any noise in excess of legally limits will be addressed.
Section I: Copper fume
The three major OELs are OSHAs permissible exposure limits (PEL), NIOSH
recommended exposure limits (REL), and ACGIH threshold limit values (TLV). OSHA PELs
are the legally enforceable limits set by the government. NIOSH as an agency of the Center for
Disease Control (CDC) which provides research and recommendation to OSHA through
recommend exposure limits (REL). ACGIH is a non-profit, non-governmental agency that
provides guidelines through TLV. TLV are normally more stringent than the legal OSHA PEL.
For copper fume OSHA and NIOSH 8-hour exposure limit is 0.1mg/m3 and ACGIH 8-hour TLV
is double the OSHA limit at 0.2 mg/m3. Acme must reduce the exposure to below the OSHA
standard.
Since ACGIH TLV of copper is uncharacteristically greater than OSHA standard it is
beneficial to understand the reasoning. In 1971, OSHA set the limit at 0.1mg/m3. ACGIH had
also set the limit to 0.1mg/m3 based on reports “the taste perception of welders was altered when
