How is your company when it comes to fire extinguishers?
Most people don't even think about fires in the workplace. In fact, many companies that we have visited over the years rarely do fire drills, let alone train employees on how to use a fire extinguisher. Seriously, go to one of your employees and ask them where the nearest fire extinguisher is from where they are. Ask them what an incipient-stage fire is or what an ABC fire extinguisher is.
What is the condition of your fire extinguishers? Are they blocked, and are they well marked as specified under 29 CFR 1910.157(c)(1)? Was the annual inspection done as specified under 29 CFR 1910.157(e)(4)? Have your employees been trained as specified under 29 CFR 1910.157(g)(1)?
Fire Extinguishers
One of the quickest ways to lose a job is to allow a fire to start. Sometimes fires do start, and then it becomes a matter of putting them out as soon as possible. The best way is to use a fire extinguisher. The key is to use it correctly! How do we learn how to use it correctly? Training!
Care and Use:
• Be sure the fire extinguishers are charged, strategically located, and ready for use.
• Everyone is responsible for checking that fire extinguishers and fire hoses (as well as other dispensing components) are not blocked.
Most fire extinguishers operate using the following P.A.S.S. technique:
• PULL – Pull the pin. This will also break the tamper seal.
• AIM LOW, pointing the extinguisher nozzle (or its horn or hose) at the base of the fire. *NOTE – Do not touch the plastic discharge horn on CO2 extinguishers. It gets very cold and may damage skin.
• SQUEEZE – Squeeze the handle to release the extinguishing agent.
• SWEEP – Sweep from side to side at the base of the fire until it appears to be out. Watch the area. If the fire re-ignites, repeat steps 2–4.
• If you have the slightest doubt about your ability to fight a fire, EVACUATE IMMEDIATELY!
Common Types of Extinguishers:
• Class A Fires: Rubbish, paper, scrap, scrap lumber. These extinguishers use soda acid and pressurized extinguishers, or water through a hose or pump-type water can.
• Class B Fires: Flammable liquids, oil, grease. These extinguishers use carbon dioxide, dry chemical, or foam extinguishers. Do not use water on these types of fires.
• Class C Fires: Electrical in nature. These extinguishers use carbon dioxide or dry chemical. Do not use foam or water-composition extinguishers.
• Class D Fires: Combustible metals, like magnesium and titanium. These extinguishers use a specialized dry powder agent such as powdered graphite, granular sodium chloride, or a copper-based metal powder.
Remember: The quickest way to put out a fire may not always be the best way.
