The state of Washington maintains stringent policies and regulations concerning fire safety. In particular, regulations on the use of fire extinguishers in places of business are defined under the provisions set forth by the Washington Industrial Safety and Health Act, or WISHA. WISHA rules apply mainly to the use, placement, testing and maintenance of fire extinguishers in the workplace, but local fire marshals may enforce additional regulations.

Selection and Distribution of Fire Extinguishers

In accordance with WISHA rules, employers must provide appropriate, readily accessible fire extinguishers in the workplace. Fire extinguishers must be mounted and located where employees can easily reach them without risking physical harm. Employers are also required to make the correct selection when choosing fire extinguishers based on the type of fire hazards that exist in the workplace. Class A fire hazards include wood, cloth, paper and rubber and require fire extinguishers to be no more than 75 feet away. Class B hazards are liquids, grease and gas and extinguishers must be within 50 feet of hazards. Class C extinguishers are used on live electrical equipment and circuits hazards. Class D hazards relate to powder, flakes and other residue from combustible metals and extinguishers must be within 75 feet.
