The Fibre-Glast Development Corporation (SIC-3079) requested an evaluation at their Dayton, Ohio facility concerning potential exposures of 1 or 2 employees during production of fibrous glass repair kits. Air samples were assessed for possible exposures to methylene-chloride (75092), butyl-cellosolve (111762), styrene (100425), general organics, total and respirable particulates and carbon-dioxide (124389). Methylene-chloride concentrations of 443 and 460 were found in 80 minute samples taken during cleaning of a mixer with methylene-chloride. NIOSH recommends that exposures to methylene-chloride should be reduced to the lowest feasible level. Organic vapors including methylene-chloride were migrating into the office area from the production area of the facility. The authors conclude that a health hazard exists for exposure to methylene- chloride. The authors recommend either substitution of a different solvent or the institution of more rigid engineering controls. Airborne concentrations of methylene-chloride in the compounding, repacking, and office areas should be reduced. Employees should wear respiratory protection while working with methylene-chloride. An air compressor located in the mixing room should also be muffled to reduce the extremely high noise level in the area.
