Controlling Exposure to Methylene Chloride (MC)
Controlling exposure to methylene chloride, a chemical commonly used in paint stripping, requires implementing various methods to ensure worker safety.
Workers in this photo are using MC to strip bathtub for refinishing.
Here are some effective methods to control exposure:
- Keep MC Vapors contained. Store and transport MC products only in approved safety containers.
- Instruct and train employees to be aware of hazards, personal hygiene, and how to use personal protective equipment.
- Instruct employees handling or using flammable liquids, gases, or toxic materials in the safe handling and use of these materials.
- Avoid breathing the air directly above areas covered with MC.
- Avoid direct skin contact with MC. Wear two pairs of gloves when using stripping solution. The inner glove should be made of polyethylene (PE)/ethylene vinyl alcohol (EVOH), PE, or laminate to prevent MC penetration. The outer glove should be made of nitrile or neoprene to protect against puncture or rips. Wear a face shield or goggles to protect your face and eyes.
- Use the washing facilities in your work area to wash off any MC from your hands and face. Use lots of soap or mild detergent and water to clean grease, oil, dirt, or anything else off your skin. Do not use MC or other organic solvents to clean your skin.
- Minimize the chance of spills and leaks. Develop and follow procedures for containing MC spills or leaks.
- Take extra precautions in low and confined spaces. MC vapors are heavier than air, so they tend to move to low, unventilated spaces.
