• Description:
  This document has been superseded and the new version can be found here. In response to a request from the International Chemical Workers Union, an investigation was undertaken of possible hazardous working conditions at the Morton Salt Company (SIC-1479), Grande Saline, Texas. Concern was expressed over asbestos (1332214) and diesel emissions at four salt mines. The study showed that the only detectable over exposures were to coal-tar pitch volatiles (CTPV) and nitrogen-dioxide (10102440) (NO2), the byproducts of combustion of petroleum based fuels. Concentrations of NO2 ranged from 0.47 to 1.4 parts per million. Airborne asbestos was not detected in 15 airborne samples collected in the mill area. Chrysotile (12001295) asbestos was identified in one of six bulk samples collected from various mill areas. Pulmonary function tests revealed decreased 1 second forced expiratory volume values for workers who currently smoked. The authors conclude that hazards existed from exposure to NO2 and CTPV in the mine. Asbestos was identified in some duct insulation. The authors recommend specific measures to reduce the these occupational exposures.
