# Fire Extinguishers - Portable (cont.) ## What you should know when using a portable fire extinguisher? (cont.) Use the correct fire extinguisher type to fight the fire. Remember, if you feel that you cannot safely extinguish the fire using the portable extinguisher available and if you have not already done so, pull the fire alarm, evacuate the area, and then call the fire department. When using an extinguisher, use the PASS system - Pull, Aim, Squeeze, Sweep. 1. Pull the pin on the extinguisher. 2. Aim the extinguisher. 3. Squeeze the trigger or top handle. 4. Sweep the fire area with the extinguisher's spray until the fire is completely out. For floor fires, sweep from the edges in. For wall fires, sweep from the bottom up. - Never walk away from a fire, even if you think it is out. The residue may reignite. - Always stand between the escape route and the fire so you can leave safely if the fire grows. - If the fire grows too large, leave the area. Activate the fire alarm to evacuate the area. ## What you should know about selecting, locating, and maintaining portable fire extinguishers? As an employer or contractor, you must: - Use the proper size of the extinguisher. - Install extinguishers according to the height requirements stated in your jurisdiction's Fire Code. - Locate extinguishers so they are readily accessible to employees for immediate use. Make sure that extinguishers are clearly visible, and any location signs are clear. - Mark or label all fire extinguishers clearly with the class of fire it is to be used for. - Make sure that the operating instructions always face outward. - Maintain extinguishers in a fully charged and operable condition. - Keep extinguishers in the designated places at all times (except during use). - Visually inspect portable fire extinguishers monthly. - Use a tag on each extinguisher that shows the dates of inspection, recharging or servicing, the name of the servicing agency, and the name of t…

Portable Fire Fighting Equipment. (a) Fire Extinguishers and Small Hose Lines. (1) A fire extinguisher, rated not less than 2A, shall be provided for each 3,000 square feet of the floor area, or fraction thereof. Where the floor area is less than 3,000 square feet at least one extinguisher shall be provided. Travel distance from any point of the protected area to the nearest fire extinguisher shall not exceed 75 feet. - One 55-gallon open container of water with two fire pails may be substituted for a fire extinguisher having a 2A rating. - A 3/4-inch diameter garden-type hose line, not to exceed 75 feet in length and equipped with an adjustable nozzle, may be substituted for a 2A-rated fire extinguisher, provided it is connected to a reliable water pressure system capable of discharging a minimum, continuous flow of 5 gallons per minute with a minimum hose stream range of 30 feet horizontally. The garden-type hose lines shall be mounted on conventional racks or reels. The number and location of hose racks or reels shall be such that at least one hose stream can be applied to all points in the floor area. - At least one fire extinguisher rated not less than 2A, shall be provided on each floor.

# WAC 296-24-592 Portable fire extinguishers. (cont.) ## WAC 296-24-[redacted postal code] Appendix A-Portable fire extinguishers. (cont.) Chapter 296-24 WAC General Safety and Health Standards Part G-3 Fire Suppression Equipment protection. The selection and distribution of fire extinguishers must reflect the type and class of fire hazards associated with a particular workplace. Extinguishers for protecting Class A hazards may be selected from the following types: Water, foam, loaded stream, or multipurpose dry chemical. Extinguishers for protecting Class B hazards may be selected from the following types: Halon 1301, Halon 1211, carbon dioxide, dry chemicals, foam, or loaded stream. Extinguishers for Class C hazards may be selected from the following types: Halon 1301, Halon 1211, carbon dioxide, or dry chemical. Combustible metal (Class D hazards) fires pose a different type of fire problem in the workplace. Extinguishers using water, gas, or certain dry chemicals cannot extinguish or control this type of fire. Therefore, certain metals have specific dry powder extinguishing agents which can extinguish or control this type of fire. Those agents which have been specifically approved for use on certain metal fires provide the best protection; however, there are also some "universal" type agents which can be used effectively on a variety of combustible metal fires if necessary. The "universal" type agents include: Foundry flux, Lith-X powder, TMB liquid, pyromet powder, TEC powder, dry talc, dry graphite powder, dry sand, dry sodium chloride, dry soda ash, lithium chloride, zirconium silicate, and dry dolomite. - Water is not generally accepted as an effective extinguishing agent for metal fires. When applied to hot burning metal, water will break down into its basic atoms of oxygen and hydrogen. This chemical breakdown contributes to the combustion of the metal. However, water is also a good universal coolant and can be used on some combustible metals, but o…
