Standard Operating Procedure: Fire Extinguisher Inspection and Emergency Usage

This Standard Operating Procedure (SOP) outlines the mandatory protocols for the routine inspection, maintenance, and emergency operation of portable fire extinguishers. Fire extinguishers are critical life-safety assets; therefore, adherence to these procedures is vital to ensure equipment readiness and operator safety during a fire event. All personnel must familiarize themselves with this document to minimize risk and maximize the effectiveness of fire suppression efforts in the workplace.

Section 1: Monthly Visual Inspection Checklist

Monthly inspections ensure that extinguishers are accessible, functional, and ready for immediate deployment. Document all findings in the site safety log.

• Accessibility: Ensure the extinguisher is in its designated location and not obstructed by boxes, furniture, or equipment.
• Signage: Verify that the wall-mounted sign identifying the extinguisher location is visible and undamaged.
• Mounting: Check that the extinguisher is securely mounted at the correct height (typically 3.5 to 5 feet from the floor) and that the cabinet or bracket is in good condition.
• Pressure Gauge: Ensure the needle is firmly in the green zone. If the needle is in the red (low or high pressure) zone, the unit must be replaced or serviced immediately.
• Safety Pin and Seal: Confirm the safety pin is intact and the tamper seal is unbroken.
• Physical Integrity: Inspect the canister for signs of dents, rust, chemical corrosion, or leaking.
• Nozzle/Hose: Check the discharge nozzle or hose for blockages, cracks, or brittle material.
• Instruction Label: Ensure the operating instructions on the nameplate are legible and facing outward.

Section 2: Emergency Operation Protocol (P.A.S.S. Method)

In the event of a fire, only attempt to extinguish the blaze if it is small, contained, and you have a clear exit path behind you. Follow the P.A.S.S. technique:

• P – Pull: Pull the safety pin located at the top of the handle. This breaks the tamper seal and allows you to discharge the agent.
• A – Aim: Aim the nozzle or hose low at the base of the fire. Do not aim at the flames themselves; aim at the fuel source.
• S – Squeeze: Squeeze the lever slowly and evenly to release the extinguishing agent.
• S – Sweep: Sweep the nozzle from side to side at the base of the fire until the flames appear to be extinguished. Maintain a safe distance (usually 6–8 feet).

Section 3: Pro Tips & Pitfalls

Pro Tips

• The "Buddy System": Always sound the fire alarm before attempting to fight a fire. If possible, have a colleague act as a lookout to monitor the fire's growth.
• Post-Use Tagging: Immediately after any discharge, even if only partial, tag the extinguisher as "EMPTY/USED" and remove it from service to trigger a refill/recharge cycle.
• Know Your Class: Familiarize yourself with the extinguisher type (e.g., Class A for wood/paper, Class B for liquids, Class C for electrical). Using the wrong agent can exacerbate certain fires.

Pitfalls

• Turning Your Back: Never turn your back on a fire, even if it appears extinguished. It may reignite. Back away slowly while keeping your eyes on the area.
• Overestimating Ability: Do not attempt to fight a fire that is larger than a standard trash can or one that is producing thick, black, toxic smoke. Evacuate immediately.
• Ignoring Expiration: Do not rely on old equipment. Ensure the unit has been professionally inspected/serviced by a certified contractor annually.

Section 4: Frequently Asked Questions (FAQ)

Q: If the extinguisher needle is in the yellow or red zone, can I still use it? A: No. If the needle is not in the green "Charged" zone, the extinguisher may fail to discharge or perform with insufficient pressure. Remove it from service immediately and contact facilities maintenance.

Q: How often do fire extinguishers need to be professionally serviced? A: Portable fire extinguishers must undergo a thorough maintenance check by a certified professional at least once every 12 months.

Q: What should I do if the fire extinguisher doesn't put out the fire? A: If the fire does not go out after your first attempt or if the fire begins to spread beyond your control, abort the effort immediately. Drop the extinguisher, exit the building via the nearest fire exit, and await the arrival of the Fire Department.
