Fire Classes

Before discussing fire extinguisher types, it’s essential to understand the different classes of fires:

• Class A: Ordinary combustibles (wood, paper, cloth)
• Class B: Flammable liquids (gasoline, oil, grease)
• Class C: Electrical equipment
• Class D: Combustible metals
• Class K: Cooking oils and fats

Types of Fire Extinguishers

1. Water and Foam Extinguishers

Suitable for Class A fires, these extinguishers cool burning materials. Foam extinguishers can also be used on Class B fires. Never use water-based extinguishers on electrical fires.

2. Carbon Dioxide (CO2) Extinguishers

Effective for Class B and C fires, CO2 extinguishers displace oxygen to smother the fire. They’re ideal for electrical fires and areas with sensitive equipment.

3. Dry Chemical Extinguishers

These versatile extinguishers are effective against Class A, B, and C fires. They work by interrupting the chemical reaction of the fire.

4. Wet Chemical Extinguishers

Designed for Class K fires, these are commonly found in commercial kitchens. They create a foam blanket to suppress the fire and prevent re-ignition.

5. Clean Agent Extinguishers

These extinguishers use halon or halocarbon agents and are suitable for Class B and C fires. They’re environmentally friendly and leave no residue.

Choosing the Right Fire Extinguisher

When selecting a fire extinguisher, consider:

• The types of fire hazards in your area
• The size of the space and potential fire
• Ease of use and portability
• Environmental and cleanup concerns

The PASS Technique

Remember the PASS technique for using a fire extinguisher:

• Pull the pin
• Aim at the base of the fire
• Squeeze the handle
• Sweep from side to side

Maintenance and Inspection

Regular maintenance is crucial for fire extinguisher effectiveness:

• Conduct monthly visual inspections
• Ensure easy access to extinguishers
• Schedule professional inspections annually
• Replace or recharge extinguishers after use

Conclusion

Understanding fire extinguisher types and their proper use is essential for workplace safety. Regular training, proper maintenance, and strategic placement of extinguishers can significantly reduce fire risks and potential damage. Remember, while fire extinguishers are crucial, employee safety is paramount. If a fire is too large or spreading quickly, evacuate immediately and call emergency services.

Key Takeaways and Best Practices

• Know the fire classes and corresponding extinguisher types
• Ensure appropriate extinguishers are available for specific hazards
• Train all employees on the PASS technique
• Conduct regular fire drills and extinguisher training
• Keep extinguishers easily accessible and clearly marked
• Never block access to fire extinguishers
• Replace or recharge extinguishers immediately after use
• Evacuate if the fire is too large or spreading rapidly
