National Occupational Health Survey of Mining. Leonardite Report.
NIOSH 1987 Jun:26 pages
Data presented were collected by the National Occupational Health Survey of Mining concerning potential exposure to chemical and physical agents for the leonardite commodity. Three leonardite mines were visited to gather this data. Two chemicals were found on the mine property that were regulated by the Mine Safety and Health Administration (MSHA). Five chemicals were found which had no NIOSH or MSHA exposure limits set. A list of 46 tradename products was included to which workers in the leonardite commodity were potentially exposed. Potential physical agents to which workers might be exposed on the sites included noise, segmental and whole body vibration and process related temperatures. Potential exposures to ten musculoskeletal system disorders were noted involving sitting, wrist movement, prone or supine lying, neck and back exertion, diminished light, awkward and heavy lifting, exertion of the forearm, arm and shoulder, and exertion of the finger and hand. Two welding processes were used at the sites: arc welding and oxyfuel gas cutting. Annual usage estimates were provided for generic and tradename chemical substances.
