Industrial Hygiene Survey of Dundee Cement Co., Dundee, Michigan. Cement Workers Morbidity Study.
NIOSH 1982 Aug:50 pages
A walk through survey was conducted at the Dundee Cement Company, Dundee, Michigan to determine the presence of materials harmful to the health of workers at that and similar sites. For most jobs at the site the respirable and total dust levels were below recommended limits. There were six respirable dust samples and three total dust samples which exceeded the recommended ACGIH levels for respirable nuisance particulate. Detectable levels of quartz (14808607) were found in 12 respirable dust samples taken from workers associated with raw material, coal, or precipitator dusts. Seven total dust samples exceeded the Mine Safety and Health Administration limit of 10mg/m3. Exposure was also noted to hydrogen-sulfide (7783064). The authors recommend that engineering controls be used to reduce worker exposure to airborne dust. Workers who experience the greatest dust levels are usually those involved in maintenance and clean up operations; respirators should be provided for these workers. Before any worker enters a confined space associated with quarry water or an area where stagnant quarry water will be disturbed, the area should be checked for concentrations of hydrogen-sulfide. Substitution of a vacuum system for the currently used compressed air would greatly lessen the current exposure to dust during clean up operations. Disposable paper or cloth respirators should not be used to protect the worker from dust.
