How to use fire extenguisher properly?
Knowing how to properly use a fire extinguisher is essential for your safety in case of a fire emergency. Fire extinguishers are designed to suppress small fires before they escalate into larger, more dangerous blazes. Here's a step-by-step guide on how to use a fire extinguisher effectively:
- Choose the Right Type of Fire Extinguisher:
- Fire extinguishers come in different classes, labeled A, B, C, D, or a combination of these letters. Each class is suitable for specific types of fires:
Class A: For fires involving ordinary combustibles like wood, paper, and cloth.
Class B: For flammable liquid fires, such as those involving gasoline, oil, or grease.
Class C: For electrical fires, where the source of the fire is an electrical appliance or wiring.
Class D: For fires involving flammable metals, like magnesium or titanium.
- Ensure you have the right type of fire extinguisher for the potential fire hazards in your environment.
- Assess the Situation:
Before attempting to use a fire extinguisher, assess the fire to ensure that it is small and contained. Fire extinguishers are only effective for small fires that you believe you can safely extinguish. If the fire is spreading rapidly or if it's already large, evacuate the area and call 911 immediately.
- Remember the PASS Technique:
PASS stands for Pull, Aim, Squeeze, and Sweep. This mnemonic can help you remember the correct steps to use a fire extinguisher:
Pull: Pull the pin or safety clip from the extinguisher to break the tamper seal.
Aim: Aim the nozzle or hose at the base of the fire, not at the flames. This is where the fire is fueled, and you want to cut off its source.
Squeeze: Squeeze the handle to release the extinguishing agent (usually a dry chemical or foam) onto the fire.
Sweep: Sweep the nozzle or hose from side to side as you discharge the agent. Continue to aim at the base of the fire and work your way toward the edges until the fire is out.

- Maintain a Safe Distance:
Stand at a safe distance from the fire, typically about 6 to 8 feet (1.8 to 2.4 meters). This distance allows you to control the extinguisher without getting too close to the flames or hazardous smoke.
- Use Short Bursts:
Use the fire extinguisher in short bursts rather than continuously spraying. This conserves the extinguishing agent and ensures you have enough to suppress the fire.
- Watch for Re-Ignition:
After the fire appears to be out, keep an eye on the area for a while to ensure there is no re-ignition. Fires can sometimes smolder and reignite, so be prepared to use the extinguisher again if necessary.
- Evacuate If Necessary:
If you're unable to extinguish the fire or if it continues to grow, evacuate the area immediately and call the fire department. Safety should always be your top priority.
- Report and Replace:
Even if you successfully extinguish a fire, it's crucial to report the incident to the fire department. Additionally, replace or recharge the fire extinguisher as soon as possible so that it's ready for future use.
Remember that fire extinguishers have limited capacity, and it's essential to know their location, type, and how to use them before an emergency occurs. Regularly inspect and maintain your fire extinguishers to ensure they are in good working condition. Fire safety is a shared responsibility, and knowing how to use a fire extinguisher can make a significant difference in protecting lives and property.
