Understanding Fire Classes: Not All Fires Are Created Equal
Before we dive into extinguishers, it’s vital to understand that fires are categorized based on the fuel they consume. Using the wrong type of extinguisher on a specific fire class can be ineffective or even dangerous. The most common fire classes are:
Class A: Ordinary Combustibles
Materials: Wood, paper, cloth, plastic, rubbish
Examples: Wastepaper baskets, furniture
Extinguisher Type: Water, Foam, Dry Chemical
Class B: Flammable Liquids
Materials: Petrol, kerosene, paints, cooking oil (excluding fats)
Examples: Garage spills, industrial solvents
Extinguisher Type: Foam, CO2, Dry Chemical
Class C: Electrical Equipment
Materials: Energized appliances, wiring, fuse boxes
Examples: Electrical panels, machinery
Extinguisher Type: CO2, Dry Chemical
Class D: Combustible Metals
Materials: Magnesium, titanium, potassium, sodium
Examples: Industrial manufacturing
Extinguisher Type: Specialty Dry Powder
Class K: Cooking Fats
Materials: Oils, animal fats, vegetable fats
Examples: Commercial kitchens, fryers
Extinguisher Type: Wet Chemical
Types of Fire Extinguishers and How They Work
Knowing the fire classes helps you choose the correct fire extinguisher type. Here are the most common types available in India and their applications :
1. Water Extinguishers (Stored Pressure Type)
- Mechanism : Cools the burning material by absorbing heat, effectively reducing its temperature below the ignition point.
- Best for : Class A fires (wood, paper, textiles).
- Avoid : Electrical fires (risk of electrocution) and flammable liquids/gases (can spread the fire).
- Key Uses : Common in offices, schools, and general public areas for ordinary combustibles.
2. Foam Extinguishers (AFFF - Aqueous Film-Forming Foam)
- Mechanism : Creates a blanket over the burning liquid, cutting off the oxygen supply and also providing a cooling effect.
- Best for : Class A and Class B fires (flammable liquids).
- Avoid : Electrical fires (conductive) and Class K fires (less effective on hot cooking fats).
- Key Uses : Ideal for workshops, garages, and areas where flammable liquids are stored.
3. Dry Chemical Powder (DCP) Extinguishers (ABC Powder Extinguishers)
- Mechanism : Interrupts the chemical reaction of the fire. The fine powder smothers the flames and forms a barrier between the fuel and oxygen.
- Best for : Class A, B, and C fires. This makes them extremely versatile.
- Avoid : Sensitive electronic equipment (can cause corrosion and damage), and typically not recommended for Class K due to cleanup and potential reignition.
- Key Uses : The most common type for homes, offices, vehicles, and general industrial use due to their broad application. Look for BIS-certified fire extinguishers for reliability.
4. Carbon Dioxide (CO2) Extinguishers
- Mechanism : Displaces oxygen, creating an inert atmosphere, and also provides a significant cooling effect.
- Best for : Class B (flammable liquids) and Class C (electrical) fires. They leave no residue, making them ideal for sensitive equipment.
- Avoid : Class A fires (can reignite if not fully extinguished), and should be used with caution in confined spaces due to oxygen displacement.
- Key Uses : Server rooms, electrical panels, laboratories, commercial kitchens, and areas with valuable electronics.
5. Wet Chemical Extinguishers
- Mechanism : Creates a soapy foam blanket that cools the fire and prevents reignition by forming a barrier over the hot cooking fats.
- Best for : Class K fires (cooking oils and fats).
- Key Uses : Commercial kitchens, restaurants, and food processing units.
6. Clean Agent Extinguishers (e.g., HFC-227ea, FK-5-1-12)
- Mechanism : Chemical interruption of the fire triangle, with minimal residue and safe for sensitive electronics.
- Best for : Class A, B, and C fires, especially in environments where water or powder would cause significant damage.
- Key Uses : Data centers, telecommunication facilities, museums, art galleries, and clean rooms. These are premium solutions for critical assets.
Master Fire Extinguisher Use with PASS
In an emergency, every second counts. The PASS method provides a simple, memorable technique for effective fire extinguisher use.
Pull
Pull the pin, breaking the tamper seal.
Aim
Aim the nozzle or hose at the base of the fire.
Squeeze
Squeeze the operating handle to release the extinguishing agent.
Sweep
Sweep the nozzle from side to side at the base of the fire until it appears to be out.
Safety First
Only attempt to extinguish a small fire if: - You have the right type of extinguisher. - The fire is small and contained. - You have a clear escape route. - You are confident in your ability. If in doubt, evacuate immediately and call emergency services.
Choosing the Right Fire Extinguisher
For Homes
- Kitchen : A small ABC powder fire extinguisher is a must-have, along with a fire blanket for small cooking fires.
- Living Areas/Bedrooms: An ABC dry chemical powder extinguisher is versatile for general combustibles.
- Garage/Workshop: Consider an ABC extinguisher, especially if you store flammable liquids.
For Businesses in India
- Offices & Retail : Primarily ABC powder extinguishers and potentially CO2 extinguishers for server rooms or electrical panels.
- Restaurants & Commercial Kitchens: Wet Chemical (Class K) extinguishers are non-negotiable. Also consider CO2 for electrical equipment and ABC for general use.
- Manufacturing & Industrial Facilities: A thorough fire risk assessment is crucial. You’ll likely need a combination of ABC, foam, and specialized Class D extinguishers depending on materials used. Compliance with BIS standards and local fire safety regulations is paramount.
- Data Centers & Server Rooms: CO2 or Clean Agent extinguishers are highly recommended to protect sensitive electronics.

Fire Extinguisher Maintenance & Inspection
A fire extinguisher is only effective if it works when needed. Follow these essential maintenance practices:
Monthly Visual Check
- Is the extinguisher accessible and visible?
- Is the pressure gauge in the green zone?
- Are the pin and tamper seal intact?
- No signs of damage, corrosion, or leakage?
Annual Professional Servicing
Indian fire safety laws require certified annual servicing. Zedex Fire ensures your extinguishers stay compliant and ready.
