| Abstract | In response to a request from the owner, an investigation was begun into methylene-chloride (75092) (MeCl) exposures at Ackerman and Sons (SIC-7641), Littleton, Colorado. Work at the shop included paint stripping, furniture repair, refinishing, and recovering. Five refinishers were employed at the site, and usually spent only a few hours stripping per week, but occasionally stripped 3 to 4 hours in one day. Personal exposures to MeCl ranged from 83 to 523 parts per million (ppm) with a time weighted average figure of 2.4 to 177ppm. Exposures to methanol (67561) ranged from 39 to 95ppm. A significant lowering of airborne concentrations of stripping compounds was noted after the stripping booth was enclosed and ventilated. Personal MeCl exposures ranged from 10 to 110ppm and 8 hour time weighted averages ranged from 0.7 to 31ppm. The authors conclude that methylene-chloride exposures did not exceed the OSHA Permissible Exposure Limit of 500ppm; NIOSH recommends that exposures be maintained at the lowest feasible concentration. The authors recommend that worker exposures to methylene-chloride be lowered. |
