2. Preparation

Before using a fire extinguisher, it’s important to take certain safety precautions to prevent injury or damage. Here are some important steps to take when preparing to use a fire extinguisher:

  1. Assess the Situation: First and foremost, assess the situation to determine if you should use a fire extinguisher or evacuate the area. If the fire is too large or spreading rapidly, evacuate immediately and call emergency services.
  2. Alert Others: If there are other people in the area, alert them of the fire and instruct them to evacuate immediately. If possible, assign someone to call emergency services.
  3. Identify the Nearest Fire Extinguisher: Locate the nearest fire extinguisher and make sure you know how to use it. If you’re not sure, read the instructions or ask for help.
  4. Familiarise Yourself with the Components: Familiarise yourself with the components of the fire extinguisher, including the nozzle or hose, and make sure you know how to aim and direct the extinguishing agent.
  5. Stand at a Safe Distance: Stand at a safe distance from the fire, usually between 6-8 feet, to avoid injury from flames or heat.

By taking these steps before using a fire extinguisher, you can minimise the risk of injury and increase your chances of successfully extinguishing the fire. Remember, safety should always be your top priority when dealing with fire.

3. Steps for Using a Fire Extinguisher – PASS

Using a fire extinguisher can be intimidating, but following these simple steps can help you use it effectively and safely:

Remember the acronym PASS: PASS stands for Pull, Aim, Squeeze, and Sweep, and it’s a useful acronym to help you remember the steps for using a fire extinguisher.

  1. P – Pull the Pin: With one hand, pull the pin located on the top of the extinguisher. This will allow you to activate the extinguisher.
  2. A – Aim at the Base of the Fire: Aim the nozzle or hose at the base of the fire, not at the flames themselves. This will help to extinguish the source of the fire, rather than just the visible flames.
  3. S – Squeeze the Handle: With your other hand, squeeze the handle of the fire extinguisher to release the extinguishing agent. Use short bursts rather than a continuous stream to conserve the agent.
  4. S – Sweep from Side to Side: Sweep the extinguishing agent from side to side across the base of the fire, keeping the nozzle or hose aimed at the base. Continue until the fire is completely extinguished.

  • Watch for Re-Ignition: Even if the fire appears to be out, keep an eye on the area for re-ignition. If the fire reignites, repeat the process or evacuate immediately if necessary.
  • Evacuate if Necessary: If the fire is too large, spreading too quickly, or you’re unable to extinguish it, evacuate immediately and call emergency services.

By following these simple steps and remembering the PASS acronym, you can use a fire extinguisher effectively and safely to put out small fires before they become larger and more dangerous.

5. How to Inspect Fire Extinguisher

Inspecting your fire extinguisher regularly is an important part of fire safety. Fire extinguishers must be checked regularly to ensure that they are in good working condition. Depending on the type of extinguisher and the environment in which it is stored, inspections should be done monthly. 

Here are the steps to properly inspect your fire extinguisher:

  1. Check the Location: Ensure that the fire extinguisher is in its designated location and is easily accessible.
  2. Verify the Expiration Date: Look at the expiration date on the extinguisher to ensure it’s still valid. If it’s expired, it may not work properly and should be replaced immediately.
  3. Check the Pressure Gauge: The pressure gauge on the fire extinguisher should be in the green zone, indicating that it’s properly pressurized. If the gauge is in the red zone or is not moving, it may need to be recharged or replaced.
  4. Inspect the Nozzle and Hose: Make sure that the nozzle and hose are not damaged, clogged, or corroded. If there’s any damage, the fire extinguisher may not work properly and should be replaced.
  5. Look for Physical Damage: Check for any physical damage on the extinguisher, such as dents, cracks, or rust. Any damage can compromise the integrity of the extinguisher and should be replaced.
  6. Ensure the Safety Pin is in Place: The safety pin on the fire extinguisher should be in place and intact. If the safety pin is missing or broken, the extinguisher may have been used or tampered with and should be inspected by a professional.
  7. Check the Instruction Label: Make sure the instruction label on the fire extinguisher is legible and facing outward. The label provides important information on how to use the extinguisher and what types of fires it can be used for.
  8. Proper Storage: Fire extinguishers should be stored in a visible and easily accessible location, away from potential hazards such as heat sources, direct sunlight, and chemicals. Storing them in a cabinet or on a wall-mounted bracket can protect them from physical damage.
  9. Servicing: It’s important to have your fire extinguisher serviced by a qualified professional at least once a year. During this service, the technician will check the condition of the extinguisher, recharge it if necessary, and replace any damaged parts.

By inspecting your fire extinguisher regularly, you can ensure that it’s in good working condition and ready to use in case of an emergency. If you notice any issues during your inspection, such as an expired or damaged extinguisher, be sure to replace it immediately. Additionally, it’s recommended to have a professional inspect your fire extinguishers regularly to ensure they’re in proper working order.
