National Occupational Health Survey of Mining. Marble (Dimension) Report.
NIOSH 1989 Dec:30 pages
This investigation concerned working conditions and identification of potential hazards at two marble (dimension) mining sites surveyed between August and September of 1987. This report identified potential exposures and provided the associated numbers of workers, the occupation of those workers and the location on the mine property where the potential exposures were observed. The information was presented in the form of seven tables: four concerned chemical agents; one concerned musculoskeletal overload conditions; one concerned physical exposure conditions; and one concerned welding processes. Estimated annual usage information was provided for chemical substances, both generic and trade names. One chemical was identified on site which is regulated by the Mine Health and Safety Administration (MHSA) guidelines regarding exposure, two which have NIOSH recommended exposure limits, and two additional chemicals which have no NIOSH recommended exposure limits or MHSA guidelines. There were 41 identified trade named products. Physical agents to which these workers were exposed included noise, segmental body vibration, temperature, and whole body vibration. Musculoskeletal overload conditions included awkward lifting; strain to the shoulder, forearm, and arm; stress to fingers and hands; heavy lifting; lower limb stress; strain to the neck and/or back regions; prone or supine lying; standing; sitting; and wrist activity. Three welding operations were noted: arc cutting, shield metal arc welding, and oxyfuel gas cutting.
