Questions and answers. Methylene chloride control in furniture stripping (revised).
Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 93-133(revised), 1997 Sep; :1-8
This pamphlet provided answers for questions commonly asked regarding the hazards of exposure to methylene-chloride (75092) during furniture stripping. Exposure to the chemical may cause short or long term health effects. Short term health effects include irritation to the skin, eyes, mucous membranes, and respiratory tract. Long term effects have been studied in laboratory animals with exposure being shown to cause cancer. OSHA established an 8 hour time weighted average exposure limit of 25 parts per million (ppm) as well as a short term exposure limit of 125ppm for a 15 minute sampling period. Engineering controls are required to reduce exposure to these concentrations. Methylene- chloride can be inhaled or absorbed through the skin. Local exhaust ventilation can be used to control exposures. Safe work practices include turning on local exhaust control systems several minutes before entering the stripping area, avoiding unnecessary transfer or movement of striping solution, keeping the face out of the air stream between the solution covered furniture and the exhaust system, keeping the face out of vapor zones above the solution and the dip tank, retrieving dropped items with a long handled tool, keeping the solution recycling system off when not in use, and covering the dip tank when not in use.
