Using a fire extinguisher effectively involves following a simple acronym called PASS: Pull, Aim, Squeeze, and Sweep.
1. Pull the Pin: Start by pulling the pin or safety clip located at the top of the extinguisher. This action breaks the seal and allows you to discharge the extinguishing agent.
2. Aim at the Base of the Fire: Stand at a safe distance, about 6 to 8 feet away from the fire. Aim the nozzle or hose at the base of the flames, not at the top. This targets the source of the fire and cuts off its fuel supply.
3. Squeeze the Handle: Firmly squeeze the handle or lever. This releases the extinguishing agent, which can be a powder, foam, or other suppressing substance. Maintain a steady grip on the handle.
4. Sweep Side to Side: Using a sweeping motion, move the nozzle or hose from side to side. Continue to aim at the base of the fire. This helps ensure that the extinguishing agent covers the entire affected area.
5. Watch for Re-ignition: After the fire appears to be out, keep an eye on the area for any signs of reignition. If the fire starts to flare up again, be prepared to use the extinguisher again or evacuate if necessary.
Remember, fire extinguishers are designed for small, contained fires. If the fire is large, spreading rapidly, or you’re unsure about using an extinguisher, prioritize your safety and evacuate the area. Always call the fire department for professional assistance. After use, even if only partially discharged, fire extinguishers should be recharged or replaced according to the manufacturer’s instructions.
