How to Use a Fire Extinguisher

Fire extinguishers are the best and most affordable way to protect property from fire damage. They are often fitted in buildings, but are also commonly carried by motor vehicles and watercrafts. There are a variety of different types of fire extinguishers, each designed for specific groups of fuel. When selecting a fire extinguisher, choose one with a UL rating and number that indicates its ability to put out the type of fire you are fighting.

Before attempting to use the fire extinguisher, ensure it is in good working order by inspecting the pressure gauge on the bottom of the unit. A low pressure gauge may indicate that it is time to recharge the extinguisher. A higher pressure gauge means the unit is more fully charged and ready to be used.

When using a fire extinguisher, it is important to remember the acronym PASS: Pull, Aim, Squeeze and Sweep. These steps help ensure that the fire is actually extinguished and the hazard is eliminated. In addition, always remember to evacuate the area once the fire has been put out; even if it appears to have been extinguished, the flames could reignite at any moment.

First, locate the nearest exit and make sure it is clear. Then, stand with your back to the exit so you can escape quickly if the fire should grow out of control. Next, move the fire extinguisher within its effective range of the fire. Keep in mind that the fire can double in size every 60 seconds, so it is important to act fast.

If the fire is not already out, sound the fire alarm and call the fire department (Triple Zero). Next, identify a safe evacuation path and keep the fire and smoke from blocking this route. Once you have a clear evacuation path, move away from the fire and stand at least 8 feet (2.44 m) from it.

Next, remove the pin or breaking a tamper seal on the top of the fire extinguisher (some have no pin). Aim low and point the nozzle or horn of the fire extinguisher at the base of the fire. Finally, squeeze the handle (some have a button instead of a lever). This depresses a mechanism that releases the pressurized agent inside the fire extinguisher.

After discharging the fire extinguisher, sweep the nozzle side to side over the fire to distribute the agent evenly. If the fire has not been extinguished, repeat the PASS process until the fire is out. If the fire continues to rage, call the fire department or evacuate the area and meet up with your evacuation plan outside of the building. Always remember to replace any empty fire extinguisher as soon as possible after use. A smoky residue from a discharged extinguisher can be as dangerous as the fire itself. It is a good idea to have extra fire extinguishers at hand, so you can easily access them when needed. The fire department can help you select the right kind of fire extinguisher for your particular needs.
