Walk-Through Survey Report of Potash Company of America, Carlsbad, New Mexico.
NIOSH 1980 Mar:6 pages
Worker exposures to diesel exhaust were studied at the Potash (584087) Company of America (SIC-1474) in New Mexico on February 12, 1980 to develop a research protocol for a retrospective epidemiologic and industrial hygiene study of potash workers. The facility employs 355 workers and has been in operation since 1934 producing ore composed mainly of sylvite (14336880) and halite (14762517) at an average of 8,300 tons per day. The current ventilation system circulates 360,000 cubic feet of air per minute. Diesel usage has been minimal since its introduction in 1967. Most of the diesel equipment is used to transport personnel, equipment, and supplies and utilizes the catalytic type emission controls and prechamber type ignition. Preemployment and periodic medical examinations are provided for the workers, along with routine industrial air sampling and periodic safety meetings. Company personnel records include complete demographic and employment history data, but records prior to 1955 would be incomplete or unavailable due to company ownership changes and a fire. The authors conclude that exposures to diesel exhaust are likely to be generalized or distributed equally throughout the mine.
