Fire Extinguisher Basics

A fire extinguisher is an essential tool to have in case of a fire emergency. Knowing how to use a fire extinguisher properly can help prevent the spread of fire and potentially save lives. Here’s a step-by-step guide on how to use a fire extinguisher effectively:

Step 1: Assess the Situation

Before attempting to use a fire extinguisher, evaluate the fire and determine if it is safe for you to proceed. If the fire is spreading rapidly, is already out of control, or if there is heavy smoke, it is best to evacuate the area and call emergency services immediately.

Step 2: Choose the Correct Fire Extinguisher

Fire extinguishers come in different classes, designed to fight specific types of fires. It is important to choose the appropriate extinguisher for the fire you are dealing with. The most common types are:

  • Class A: for fires involving ordinary combustible materials like wood, paper, or fabric.
  • Class B: for fires involving flammable liquids like gasoline or oil.
  • Class C: for fires involving electrical equipment such as appliances or outlets.
  • Class D: for fires involving flammable metals.
  • Class K: for fires involving cooking oils and fats typically found in kitchens.

Ensure you have the right type of extinguisher for the fire at hand to avoid exacerbating the situation.

Step 3: Remember the PASS Technique

Most fire extinguishers operate using a universal method known as the PASS technique. The steps involved are as follows:

  1. Pull the safety pin: This pin locks the extinguisher and prevents accidental discharge. Hold the extinguisher upright and firmly grasp the nozzle or hose assembly.
  2. Aim the extinguisher nozzle: Point the nozzle or hose at the base of the fire where the fuel source is concentrated, not at the flames.
  3. Squeeze the handle: Squeeze the handle to release the extinguishing agent. Keep your grip firm but avoid using excessive force.
  4. Sweep from side to side: Using a sweeping motion, move the extinguisher’s nozzle or hose from side to side, covering the entire area of the fire. Continue until the fire is completely out or the extinguisher is empty.

Step 4: Maintain a Safe Distance

While using a fire extinguisher, stand at a safe distance from the fire. Maintain a distance of about 6 to 8 feet (1.8 to 2.4 meters) to prevent heat, smoke, or flying debris from causing harm.

Step 5: Evacuate if Necessary

If the fire continues to grow or the extinguisher runs out before the fire is adequately suppressed, immediately leave the area. Close doors and contain the fire as best as possible until professional help arrives.

Remember, fire extinguishers are designed to handle small fires. If a fire becomes uncontrollable, evacuate the premises and contact emergency services.

By following these steps and exercising caution, you can effectively use a fire extinguisher and potentially stop a fire from escalating. Stay prepared and ensure others around you also understand how to use this important firefighting tool.
