Abstract
Environmental sampling was conducted and a medical questionnaire was administered on April 30 and May 1, 1980, at Texaco (SIC-2911), Casper, Wyoming, to determine employee exposure to toxic concentration iron-oxide (1309371), manganese (7439965), aluminum (7429905), copper (7440508), nickel (7440020), and fluoride (16984488). A representative of the Oil Chemical Atomic Workers, Local Union 2-230, requested the evaluation on behalf of six workers in the welding shop. Iron-oxide concentrations ranged from 0.1 to 1.3 milligram per cubic meter (mg/cu m compared with the recommended threshold limit value (TLV) of 5.0 mg/cu m recommend by the American Conference of Government Industrial Hygienists (ACGIH). Manganese ranged from less than detectable to 0.05 mg/cu m compared with the ACGIH permissible exposure limit of 5.0 mg/cu m. Aluminum ranged from less than detectable to 0.04mg/cu m, well below the ACGIH permissible exposure limit of 5.0mg/cu m). Copper ranged from less than detectable to 0.01mg/cu m, below the OSHA standard 0.1mg/cu m). Nickel ranged from less than detectable to 0.01mg/cu m; the OSHA standard is 1.0mg/cu m. Lead and fluoride were less than detectable. The medical questionnaire failed to identify any work- related employee health problems. The author concludes that no exposure hazards exist at this facility, but recommends that all mechanical exhaust systems be well maintained, and that good personal hygiene and work practices be followed by all employees.
