NIOSH 1985 Apr:22 pages
An indepth survey of an acrylamide (79061) sewer grouting operation performed at Savage Walker Schulte Associates (SIC-7699), Cincinnati, Ohio was conducted in September, 1984. The grouting operation was part of a sewer line repair job performed under contract to the Metropolitan Sewer District of Hamilton County. Personal air monitoring of two workers was performed. Work practices were observed. Personal acrylamide exposures averaged standard for acrylamide is 0.3mg/m3. Neither of the employees wore coveralls, rain gear, or had a change of clothes. The employee who mixed the grouting material wore a respirator intended for dust and mist. The effectiveness of the respirator was reduced because the employee had a short beard. Each employee wore waterproof gloves; however, the gloves were old, worn, and cracked. Sixty five micrograms of acrylamide were recovered from the inside of one of the gloves. The author concludes that the employees are at high risk of being dermally exposed to acrylamide. Recommendations include substituting an acrylate or urethane grout for the acrylamide grout if feasible and using waterproof gloves lined with cloth.
