• Description:
  Environmental evaluations were conducted on December 19 to 21, 1978, at the Stauffer Chemical Company (SIC-5161) in Silver Bow, Montana in response to a request from Teamsters Local Number 2 in Butte, Montana, to determine potential toxic exposures associated with the processing of ore and the production of elemental-phosphorus (7723140) (P4) among 75 to 80 workers. Breathing zone and general room air samples were analyzed for phosphorus-pentoxide (1314563) (P2O5), elemental-phosphorus, crystalline-silica (7631869), total particulate, fluoride, and vanadium-pentoxide (1314621). Concentrations of P2O5 ranged from 1.7 to 9.2 milligrams per cubic meter (mg/cu m). No OSHA criteria currently exists for this compound. In 3 out of 4 respirable crystalline-silica samples, concentrations ranging from 0.09 to 0.183mg/cu m exceeded the OSHA standard of 10mg/cu m divided by the percent of respirable quartz (14808607) plus 2. All other samples were within the most recent evaluation criteria. The author concludes that a potential health hazard from excessive airborne concentrations of P2O5 and respirable crystalline-silica existed and recommends maintaining the current respirator program, insuring proper fit of respirators, briefing workers on potential hazards, and improving local and general ventilation.
