Fire Extinguisher Types in India

A fire can spread within seconds, and having the right fire extinguisher nearby can make an important difference during the early stage of a fire. However, not every fire extinguisher is designed for every type of fire. Using the wrong extinguisher can be ineffective and may create additional hazards.

In India, fire extinguishers are selected according to the type of fire risk, the extinguishing agent and applicable fire safety standards. BIS guidance covers the selection, installation, maintenance and testing of portable and mobile fire extinguishers.

This guide explains the major types of fire extinguishers used in India, the fires they are designed for and how to choose the right option for your home, office, factory, warehouse or commercial property.

What Is a Fire Extinguisher?

A fire extinguisher is a portable or mobile device containing an extinguishing agent that can be discharged to control a small, early-stage fire.

Fire extinguishers are considered a first line of defence against incipient fires. They do not replace fire alarms, evacuation procedures, fixed fire protection systems or professional firefighting services.

The correct extinguisher depends primarily on what is burning.

Understanding Different Fire Classes

Before choosing a fire extinguisher, it is important to understand the different classes of fire.

Class A Fire

Class A fires involve ordinary combustible materials such as:

• Wood
• Paper
• Cloth
• Rubber
• Furniture
• Some plastics

Water, foam, ABC dry chemical powder and certain clean-agent extinguishers may be suitable depending on the application and extinguisher rating.

Class B Fire

Class B fires involve flammable liquids or liquefiable solids such as:

• Petrol
• Diesel
• Paint
• Solvents
• Wax
• Certain oils and chemicals

Foam, dry chemical powder, CO2 and suitable clean agents can be used for applicable Class B risks.

Class C Fire

Under the BIS classification, Class C refers to fires involving flammable gases under pressure, including gases such as LPG and other combustible gases.

Suitable extinguishing agents can include dry chemical powder, CO2 and appropriate clean agents, depending on the specific hazard and extinguisher rating.

Class D Fire

Class D fires involve combustible metals such as:

• Magnesium
• Aluminium
• Sodium
• Potassium
• Other combustible metals

These fires require specialised extinguishing agents specifically designed for the particular metal involved.

Class F Fire

Class F fires involve cooking oils and fats and are commonly associated with commercial kitchens.

Wet chemical extinguishers are designed for this type of fire.

Main Types of Fire Extinguishers in India

Different extinguishing agents are designed for different hazards. Some of the commonly used types include water, foam, dry chemical powder, CO2, clean agent and wet chemical extinguishers.

1. Water Fire Extinguisher

Water extinguishers are primarily designed for Class A fires involving ordinary combustible materials.

Suitable for:

• Paper
• Wood
• Cloth
• Furniture
• Other ordinary combustible materials

Common applications:

• Offices
• Schools
• Residential areas
• Warehouses containing ordinary combustibles
• Certain commercial buildings

Do not use on:

Water should not be used on live electrical equipment or flammable-liquid fires where it may create additional hazards.

Always check the extinguisher label and rating before use.

2. Foam Fire Extinguisher

Foam extinguishers are commonly used for Class A and Class B fire risks.

The foam forms a layer over the burning material or liquid, helping suppress the fire and reduce the release of flammable vapours.

Suitable applications include:

• Petrol and fuel storage areas
• Workshops
• Warehouses
• Commercial premises
• Areas with flammable-liquid risks

Foam extinguishers should not be used on electrical equipment unless the specific extinguisher is approved and rated for that application.

3. ABC Dry Chemical Powder Fire Extinguisher

ABC dry chemical powder extinguishers are widely used for general fire protection because they can address several common fire risks.

Depending on the extinguisher’s certification and rating, ABC powder extinguishers can be suitable for Class A, Class B and Class C fires.

Common applications:

• Offices
• Factories
• Shops
• Warehouses
• Workshops
• Commercial buildings
• General industrial areas

ABC extinguishers are particularly useful where a property has multiple common fire hazards.

However, powder residue can contaminate equipment and sensitive electronic systems. Therefore, another suitable extinguishing agent may be preferable for areas containing sensitive electronics.

4. CO2 Fire Extinguisher

Carbon dioxide or CO2 extinguishers are commonly used for certain Class B and electrical hazards.

One of their major advantages is that CO2 does not leave the powder residue associated with dry chemical extinguishers.

Common applications:

• Electrical panels
• Control rooms
• Computer equipment
• Server areas
• Laboratories
• Offices with electrical equipment

For electrical hazards, always use an extinguisher specifically rated and suitable for the equipment and situation. Never use water on energised electrical equipment.

5. Clean Agent Fire Extinguisher

Clean-agent extinguishers are designed for environments where minimising residue and equipment contamination is important.

They may be considered for areas containing:

• Computers
• Servers
• Communication equipment
• Control systems
• Sensitive electronic equipment

The appropriate clean agent should be selected based on the specific fire risk, equipment and applicable standards.

6. Wet Chemical Fire Extinguisher

Wet chemical extinguishers are specifically designed for cooking-oil and fat fires, which fall under Class F in BIS guidance.

They are particularly important in:

• Restaurants
• Hotels
• Commercial kitchens
• Canteens
• Food-processing areas

A commercial kitchen should have fire protection designed specifically for its cooking hazards rather than relying on a general-purpose extinguisher alone.

Fire Extinguisher Selection Guide

The following simplified guide can help you understand which extinguisher may be appropriate for different fire risks:

Fire Risk	Examples	Common Suitable Extinguishing Agents
Class A	Wood, paper, cloth	Water, foam, ABC powder
Class B	Petrol, diesel, paint, solvents	Foam, DCP, CO2, clean agent
Class C	LPG and flammable gases	DCP, CO2, suitable clean agent
Class D	Magnesium, sodium, potassium	Specialised metal-fire powder
Class F	Cooking oil and fats	Wet chemical

The final selection should always be based on the actual hazard, extinguisher rating and applicable standards rather than simply choosing an extinguisher by name.

Which Fire Extinguisher Is Best for an Office?

There is no single extinguisher that is automatically best for every office.

An office may contain several potential hazards, including:

• Paper and furniture
• Electrical equipment
• Computers
• UPS systems
• Server equipment
• Pantry or kitchen facilities

ABC dry powder may provide general-purpose protection for applicable fire risks, while CO2 or an appropriate clean agent may be considered for electrical and sensitive electronic equipment.

A proper fire-risk assessment should determine the appropriate combination, quantity and placement.

Which Fire Extinguisher Is Best for a Factory?

Factories can have significantly more complex fire risks than offices.

Depending on the manufacturing process, a factory may contain:

• Electrical machinery
• Flammable liquids
• Gas cylinders
• Packaging materials
• Chemicals
• Combustible metals
• Raw materials

Therefore, factories may require multiple types of extinguishers positioned according to their specific hazards.

Selecting extinguishers based only on the size of the building is not sufficient. The type of materials, processes and equipment present should also be considered.

Which Fire Extinguisher Is Best for a Warehouse?

Warehouses often contain large quantities of combustible materials such as cardboard, paper, packaging and plastics.

Depending on the stored materials, additional risks may include flammable liquids, gases or chemicals.

ABC dry powder and water or foam extinguishers may be appropriate for certain Class A and Class B risks, but the final selection should be based on the warehouse’s specific fire-risk assessment and applicable standards.

Which Fire Extinguisher Should Be Used for an Electrical Fire?

Electrical equipment requires particular care.

For an energised electrical hazard, use only an extinguisher that is specifically suitable and rated for that application. CO2 and certain clean agents are commonly used because they are non-conductive and leave little or no residue.

The power supply should be isolated if this can be done safely. Once equipment is de-energised, the remaining fire risk should still be assessed based on the material that is burning.

BIS guidance specifically notes that non-conductive extinguishing agents are necessary for energised electrical equipment.

What Should You Check Before Buying a Fire Extinguisher?

Choosing a fire extinguisher involves more than selecting a size.

Before purchasing, consider:

1. Identify the Fire Risk

Determine what materials or equipment could potentially catch fire.

2. Check the Extinguisher Rating

The extinguisher should be appropriately rated for the identified fire hazard.

3. Check Applicable Standards

Choose compliant products meeting applicable Indian standards and certification requirements.

4. Consider the Location

An extinguisher for a kitchen may need to be different from one intended for an electrical room or warehouse.

5. Consider Equipment Sensitivity

Powder residue may be undesirable around sensitive electronic equipment.

6. Consider Accessibility

An extinguisher should be easily accessible and located where people can reach it quickly during an emergency.

7. Plan for Maintenance

A fire extinguisher is useful only when it is properly maintained and ready for operation.

Why Fire Extinguisher Maintenance Is Important

Simply installing an extinguisher does not guarantee that it will work when required.

According to IS 2190:2024, extinguishers should be maintained in a fully charged and operable condition and kept in their designated locations when not in use.

Regular checks should consider factors such as:

• Physical damage
• Pressure condition where applicable
• Seal and safety pin
• Hose or nozzle condition
• Accessibility
• Corrosion
• Service and recharge requirements
• Overall operating condition

Maintenance should be carried out by competent personnel according to applicable requirements.

Common Mistakes to Avoid

Using Water on Electrical Fires

Water can create a serious electrical hazard when equipment is energised.

Using the Wrong Extinguisher

A fire extinguisher must match the fire hazard.

Keeping Extinguishers Hidden

Fire extinguishers should be accessible and easy to identify during an emergency.

Ignoring Maintenance

An expired, damaged or discharged extinguisher may not perform when needed.

Buying Only Based on Price

Fire safety equipment should be selected based on suitability, quality, certification and compliance rather than price alone.

Fire Extinguishers Are the First Line of Defence

Portable fire extinguishers are designed primarily to tackle small, early-stage fires. They are not intended to replace a complete fire protection system.

A comprehensive fire safety plan may also include:

• Fire alarm systems
• Smoke detectors
• Fire hydrant systems
• Sprinkler systems
• Emergency lighting
• Fire exits
• Fire safety signage
• Evacuation plans
• Regular fire safety training

The right combination depends on the building type, occupancy, fire load and applicable regulations.

Final Thoughts

Choosing the right fire extinguisher is an important part of an effective fire safety plan. Water, foam, ABC dry powder, CO2, clean-agent and wet chemical extinguishers all have different applications.

The most important rule is simple: identify the fire risk first and then select an extinguisher that is properly rated for that hazard.

For homes, offices, factories, warehouses and commercial buildings, professional fire-risk assessment and proper installation can help ensure that fire extinguishers are positioned and maintained correctly.
