Fire extinguishers serve as a first line of defense against small fires. Whether it’s a kitchen fire, an electrical short, or a fire that has started in a trash can, having a fire extinguisher nearby can prevent an emergency from escalating. The immediate action of using a fire extinguisher can stop a small fire from spreading and causing devastating damage.

It is essential to know which type of fire extinguisher is appropriate for different kinds of fires. There are several types of extinguishers, each designed to handle specific fire classes:

• Class A: For ordinary combustibles like wood, paper, and cloth.
• Class B: For flammable liquids such as gasoline, oil, and grease.
• Class C: For electrical fires involving wiring, circuit breakers, or appliances.
• Class D: For fires involving flammable metals.
• Class K: For kitchen fires, particularly those involving cooking oils and fats.

Understanding the right fire extinguisher for each fire type can prevent further danger. For example, using a water-based extinguisher on an electrical fire can lead to electrocution.

In emergencies, it’s not just having a fire extinguisher that matters, but also knowing how to use it properly. Fire extinguishers operate under a simple method known as PASS:

• Pull the pin: This breaks the tamper seal and allows you to operate the extinguisher.
• Aim the nozzle: Point it at the base of the fire, not the flames.
• Squeeze the handle: This releases the extinguishing agent.
• Sweep from side to side: Move the nozzle in a sweeping motion to cover the fire completely.

Remember, if the fire is too large or spreading rapidly, evacuating the area and calling the fire department is the safest option.

To ensure fire extinguishers are ready to use in case of emergency, regular maintenance is essential. Here’s what to check:

• Pressure Gauge: Ensure the needle is in the green zone. If it’s low, recharge or replace the extinguisher.
• Physical Condition: Check for dents, rust, or any signs of damage that could affect its functionality.
• Expiry Date: Fire extinguishers typically have a shelf life. Make sure it’s still within the date for safe use.
• Annual Inspections: Many fire safety standards require professional inspection once a year to ensure the fire extinguisher is in working condition.

Knowing how to operate a fire extinguisher is not enough. In high-stress situations, it’s easy to forget the correct steps. Therefore, regular fire safety training should be part of workplace safety programs. This training should include:

• Identifying potential fire hazards
• Understanding fire extinguisher labels and classifications
• Practicing how to use the fire extinguisher
• Knowing when to evacuate rather than fight a fire
