Section 437-004-1450 - Extinguishers

NOTE: The Oregon Office of State Fire Marshal and local fire authorities also have rules that apply to portable fire extinguishers.

(1) Provide the class of fire extinguishers designed for use on the class of fire potential in the work area.

NOTE: To make it easy to use the right extinguisher, the NFPA 10 Extinguisher Standard uses the following system of classification: Class A: Fires of ordinary combustible materials (such as wood, cloth, paper, rubber, and many plastics) requiring the heat-absorbing (cooling) effects of water, water solutions or the coating effects of certain dry chemicals that retard burning. Class B: Fires of flammable liquids, flammable gases, grease and similar materials where extinguishment is best done by excluding air (oxygen), inhibiting the release of combustible vapors or interrupting the combustion chain reaction. Class C: Fires of energized electrical equipment where safety to the operator requires the use of electrically nonconductive extinguishing agents. (Note: For nonenergized electrical equipment, Class A or B extinguishers may be best.) Class D: Fires of certain combustible metals, such as magnesium, titanium, zirconium, sodium, potassium, etc., requiring a heat-absorbing extinguishing medium not reactive with the burning metals.

(2) Original labels and marking on extinguishers must remain attached and legible.

(3) Mount fire extinguishers on hangers, brackets, in cabinets or on shelves. The maximum height of the top of the extinguisher above the floor is: [Table not included. See ED. NOTE.]

(4) Do not obstruct fire extinguishers. They must be in plain sight or clearly mark their location.

(5) Paths to and space in front of fire extinguishers must be clear and free from obstruction.

(6) Inspect fire extinguishers yearly or more often as needed to keep them usable and fully charged.

(7) Do not use fire extinguishers with carbon tetrachloride, chlorobromomethane or other toxic vaporizing fluids.
