HETA Report No. MTA-78-101-109, Accidental Oil Shale, Incorporated, Logan Wash, Colorado.
NIOSH 1980 Aug:22 pages
An environmental and personnel survey was conducted on September 6 and 7, 1979 at the Occidental Oil Shale, Incorporated Oil Shale Mine in Logan Wash, Colorado. Concentrations of lead (7439921), cadmium (7440439), beryllium (7440417), benzo(a)pyrene (50328), chrysene (218019), pyrene (129000) and benz(a)anthracene (56553) were below detectable limits. Traces of methylfuran (534225), phenol (108952), strontium (7440246), benzene (71432) and fluoranthene (206440) were found. None of the carbon-dioxide (124389) samples exceeded the evaluation criteria. Personal exposures to benzene were below the evaluation criteria but benzene concentrations were above the evaluation criteria in the production mine return airways. Some workers complained of headaches and irritation of the finger tips. The author suggests various environmental controls, and recommends that regular medical examinations be provided for the workers.
