This information applies to the voluntary use of respirators. Respirators protect against airborne hazards when properly selected and used.

Voluntary use of respirators is permitted as long as exposure to substances remains below the Washington Industrial Safety and Health Act (WISHA) permissible exposure limits (PELs) or there is no exposure to an airborne biological hazard. Voluntary use of respirators can provide you an additional level of comfort and protection.
