How to Use a Fire Extinguisher

A fire extinguisher is a valuable first line of defense in the event of a fire. It can help snuff out smaller flames, clear an escape path, and reduce the amount of damage done to a property or person. However, a fire extinguisher’s effectiveness depends on the way it is used. As a result, it is important to familiarize yourself with the various types of fire extinguishers and what they are capable of doing in order to use them effectively in the event of a fire.

There are five types of fire extinguisher, and each type has a different role in fighting fires. Class A extinguishers contain water that smothers the fire, class B extinguishers have a dry chemical agent that does the same, class C extinguishers have a powdered dry chemical that does the same, and class D extinguishers have a monoammonium phosphate (MAP)-based chemical that is effective on electrical fires. Each extinguisher is marked with a picture symbol that indicates what kind of fire it is designed to combat.

When using a fire extinguisher, it is important to follow the PASS method. This includes identifying an exit, sounding the alarm, and calling the fire department before moving towards the fire. It is also important to have a plan in place for an escape route should you be unable to extinguish the fire with your fire extinguisher. Finally, it is a good idea to share the location of your fire extinguishers with babysitters, house sitters, and anyone else that may need to know where it is located in case of an emergency.

The first step in operating a fire extinguisher is to pull the pin at the top of the unit, which breaks the tamper seal. It is then important to aim low at the base of the fire, rather than at the flames themselves, and to sweep from side to side with the hose or nozzle in a sweeping motion until the area appears to be fully extinguished. After discharge, be sure to sweep up any residue and call the fire department so they can survey the area for signs of re-ignition.

It is also a good idea to have regular fire extinguisher maintenance and inspections, especially when they are due for refills. Performing routine checks can help ensure that the pressure gauge is in the recommended range and that there are no blockages in the hose or nozzle. The tamper seal and pin should also be checked to ensure that they are secure. In addition, a thorough inspection can help to prevent dents or damage that might hinder the release of the suppressant. This can be accomplished by a professional, or can be done by the homeowner with a basic set of tools. This is a great time to test the pin and tamper seal, as well as the hose and nozzle for signs of wear or blockages. The cylinder should be free of rust or dents that could prevent the suppressant from escaping.
