If you determine that it is appropriate to use an extinguisher, quickly check it to be sure it appears to be in working order. Then carry it to the fire, and remember the simple acronym PASS. • Pull the pin. Some fire extinguishers require releasing a lock latch, or pressing a puncture lever, or other motion. • Aim the nozzle, horn, or hose low at the base of the fire. • Squeeze the handle. This releases the extinguishing agent. • Sweep from side to side at the base of the fire, until it appears to be out. After the fire appears to be out, watch the area in case the fire breaks out again, and repeat use of the extinguisher if necessary. Depending on the type of fire and extinguisher, you may have to apply the suppressant to the fire in a rain-down manner instead of aiming at the base of the fire. Make sure you know how to use the type of extinguishers available at your home and workplace.
