Complete Fire Extinguisher Buying Guide For Businesses & Facilities

Having a fire extinguisher is crucial to the safety of your restaurant, employees, and customers. It is a non-negotiable aspect of any business operation. In the UAE, having the right fire extinguisher on hand can mean the difference between a minor incident and a catastrophic disaster.
You must understand everything about buying fire extinguishers for businesses and facilities. In this blog post, we will share the different fire classes, types of fire extinguishers for commercial use, how to determine the right extinguisher size, and how many fire extinguishers a business needs.

Understanding Fire Classes

Fires are classified into five classes based on the type of combustible material involved, and each class requires a specific type of extinguishing agent to be effective.
Class A: Fires involving ordinary combustible materials such as paper, cloth, plastics, and wood.
Class B: Fires involving flammable liquids and gases, such as propane, oil, and gasoline.
Class C: Fires involving energized electrical wiring or electrical equipment.
Class D: Fires involving combustible metals, such as potassium, titanium, and magnesium.
Class K: Fires involving greases and cooking oils, typically found in commercial kitchens.

Types of Fire Extinguishers For Commercial Use

Water Extinguishers

This is the most common and traditional type of fire extinguisher, work by cooling the burning material to a point where combustion can no longer occur. For specific risks, they are a reliable and cost-effective solution.
Best for: Class A fires involving solid combustibles.
NEVER use on: This can spread the fire or cause electrocution, so never use on electrical fires, flammable liquids, or cooking fat fires.
Common Locations: Offices, retail shops, warehouses, schools, and storage of general combustible materials.

Foam Extinguishers

Foam extinguishers offer a dual-action approach. They cool the fire like water and also create a sealing film over the fuel's surface, cutting off the oxygen supply and preventing re-ignition. This makes the foam extinguisher more versatile than others.
Best for: Class A and Class B fires.
Not suitable for: Commercial kitchen fires or significant electrical hazards.
Common Locations: Petrol stations, factories, workshops, and offices.

CO2 Extinguishers

CO2 extinguishers displace the oxygen in the air to have a rapid cooling effect and suffocate the fire. Their primary benefit is that they are a clean agent, so does not leave any residue behind after discharge.
Best for: Class B flammable liquid fires and live electrical equipment.
Key Benefit: Ideal for protecting sensitive machinery and electronics without causing damage.
Common Locations: Electrical switch rooms, server rooms, and offices with high-value IT equipment.

Dry Powder Extinguishers

Also referred to as ABC extinguishers, these units combat fires by creating a protective layer over the burning material, cutting off oxygen, and interrupting the fire’s chemical reaction. While their multi-purpose capability makes them highly versatile, they must be used with proper caution.
Best for: Class A, B, and C fires, and safe for use on live electrical equipment as well.
Cautions: In enclosed spaces, the powder can obscure vision and cause breathing difficulties. Cleanup can also be extensive.
Common Locations: Workshops, outdoor areas, vehicles, and premises with mixed fire risks.

Wet Chemical Extinguishers

Wet Chemical Extinguishers are specifically used for the unique dangers of commercial cooking environments. The extinguishing agent is released as a fine spray that cools the flames and reacts with heated cooking oils through a process known as saponification. This reaction forms a thick, soap-like layer over the surface, sealing it off and preventing the fire from reigniting.
Specifically designed for: Class F fires involving cooking oils and deep-fat fryers.
Also effective on: Class A fires.
Common Locations: Essential for restaurants, canteens, commercial kitchens, and food processing plants.

How To Determine The Right Extinguisher Size

1. Assess Fire Risk Level

Low-risk areas like offices may only need 2 kg or 4 kg units. Higher-risk environments, such as warehouses or workshops, typically require 6 kg or 9 kg extinguishers for greater capacity.

2. Consider the Size of the Facility

Larger spaces require proper coverage based on travel distance guidelines. It’s often better to install multiple extinguishers rather than relying on one large unit.

3. Check the Fire Rating

Look at the extinguisher’s rating (e.g., 2A: 10 Choosing the right fire extinguisher for your business is not just about meeting legal requirements — it is about protecting lives, property, and business continuity.B: C). Higher ratings indicate greater fire-fighting capability. Match the rating to your specific hazards.

4. Ensure Easy Handling

The extinguisher should be easy for staff to lift and operate. Smaller units are ideal for general use, while larger ones may require trained personnel.

5. Follow Local Regulations

Always comply with local fire safety codes regarding minimum size, placement, and quantity.

How Many Fire Extinguishers Does A Business Need

The number of fire extinguishers required depends on the facility’s size, layout, and level of fire risk. There is no specific size that fits all answers; proper placement and compliance are key.

• Based on Floor Area – Fire safety guidelines typically require extinguishers to be placed within a specific travel distance (often 15–23 meters, depending on hazard level). Larger spaces require more units to maintain coverage.
• Type of Business Activity – Offices may need fewer extinguishers compared to factories, warehouses, or workshops where fire risks are higher.
• Hazard Zones – High-risk areas such as kitchens, electrical rooms, storage areas, and fuel handling zones require dedicated extinguishers suitable for those specific risks.
• Number of Floors – Each floor of a building should have its own properly placed extinguishers.
• Local Fire Regulations – Always follow local fire codes, which may specify minimum quantities and types based on occupancy classification.

In most cases, businesses should install multiple extinguishers strategically throughout the facility rather than relying on a single unit. A professional fire risk assessment can help determine the exact number needed for full compliance and protection.
