• Description:
  Worker exposures to diesel exhaust were surveyed at the Potash Mines of International Minerals and Chemical, Incorporated (SIC-1474) in Carlsbad, New Mexico, on February 8, 1979. The facility was under consideration for inclusion in a NIOSH epidemiological study of potash workers exposed to diesel exhaust. The company employed 245 underground miners, and the ore produced from the mine contained sylvite, langbeinite and halite. Mining was performed 800 to 900 feet underground. Sixty seven diesel units were used underground and 19 were used above ground. Ventilation in the mine was provided by two exhaust and two intake shafts. Personnel records provide demographic data, date of hire, and information of preemployment physical status. Preemployment physicals were provided, but no periodic examinations were offered. Concentrations of carbon- monoxide (630080) and nitrogen-dioxide (10102440) at a field station were 5 and 0.8 parts per million, respectively, while concentrations of carbon-monoxide and carbon-dioxide (124389) at an active entry face were 8 to 9 and 250ppm, respectively. Nitrogen-dioxide concentrations had to fall below 4ppm after blasting before workers could reenter the area. The author concludes that information concerning exposures prior to 1967 is needed, since the use of diesel equipment by this company occurred primarily after 1967. He notes that this data may be available from the State of New Mexico Mine Inspection Office. [Description provided by NIOSH]
