How Many Fire Extinguishers Are Required on Business Premises? The number of fire extinguishers required in business premises depends on the size, use, and layout of the premises and the relevant local and national fire safety regulations. The fire extinguishers should be appropriate for the type and size of the fire risks and be located in easily accessible places.

From small businesses to large ones, fire extinguishers are a must-have for all businesses. But do you know how many extinguishers you need to keep your business safe? Find out the answer and protect your premises now.

The number of extinguishers required for business premises will depend on the size of the building and the type of hazard present. For most business premises, one fire extinguisher per 200 square meters is a common rule of thumb. However, larger businesses may require more extinguishers, depending on their size and the types of hazards present.

Requirements for Businesses

All business premises must be outfitted with the smallest of fire extinguishers for every 3,000 square feet of floor space. Business premises should install these extinguishers in areas of high risk, such as kitchens, warehouses, and laboratories.

Fire extinguishers should be located in easily accessible locations and kept in good working order. These should be clearly labeled with their type and size. Businesses should inspect fire extinguishers regularly and replace or repair any damaged or expired extinguishers.

Types of Fire Extinguishers

Knowing the different fire extinguisher types is as crucial as knowing how many to use. There are different classes of fires, and each requires a specific type of fire extinguisher. The classes are:

Class A: Ordinary Combustibles

Class A fires involve ordinary combustible materials like wood, paper, and cloth. It is crucial for businesses with many flammable materials, like warehouses, to have multiple Class A extinguishers placed strategically.

Class B: Flammable Liquids

Flammable liquids like gasoline, oil, and solvents fall under Class B fires. Industries that use flammable liquids or chemicals should have enough Class B extinguishers.

Class C: Electrical Fires

Class C fires stem from electrical equipment such as wiring, appliances, and circuit breakers. Offices and businesses with a lot of electronic equipment need Class C extinguishers. These extinguishers can put out electrical fires.

Class D: Combustible Metals

Industries working with combustible metals like magnesium and titanium might face Class D fires. These fires need special extinguishers called Class D. They are made for these unique dangers.

Class K: Cooking Fires

Class K fires involve cooking oils and fats, often found in commercial kitchens. Restaurants and other places that serve food need special fire extinguishers for kitchen fires.

Calculating Fire Extinguisher Requirements

The number of extinguishers needed will depend on the size, layout, and type of business, as well as the potential risks in the premises. To ensure your business meets the necessary fire safety requirements, it is important to determine the total number of extinguishers needed.

Factors Influencing the Number of Fire Extinguishers

The number of fire extinguishers needed at a business is based on factors like size, layout, and type. Here are some key considerations:

Size and Layout of the Premises

The size and layout of your business premises play a crucial role in determining the number of fire extinguishers needed. If the spaces or buildings are bigger, you might need more fire extinguishers for good coverage. In places like kitchens, storage rooms, and machinery spaces, more fire extinguishers might be necessary. These areas have a greater risk of fire.

Fire Hazard Assessment

To find out how many fire extinguishers you need, assess fire hazards carefully. Different types of businesses involve varying degrees of fire hazards. For example, a restaurant with an open kitchen has different needs than a retail store.

Maintenance of Fire Extinguishers

The number of fire extinguishers required in business premises will depend on the size and type of business. Generally, it is recommended that there should be at least one fire extinguisher for every 3,000 square feet of floor space or one fire extinguisher per floor.

Visual Inspections

When it comes to fire safety, it is important to ensure that all business premises are equipped with the right number of extinguishers. This visual inspection will assess how many extinguishers are required on business premises. First and foremost, the type of business must be determined. Is it a restaurant, a retail store, an office building, a warehouse, or a manufacturing facility? Each type of business has different fire safety requirements. 

Annual Maintenance

Annual maintenance is a critical part of any business, and this is especially true when it comes to fire safety. Ensuring that a business premise has the correct number of fire extinguishers is essential for protecting employees, customers, and visitors. To determine the number of fire extinguishers required, the size of the premises must be taken into account.


The amount of fire extinguishers needed in a business depends on the size of the business and what type of business it is. It also depends on the fire risk assessment. Fire safety regulations must be tracked to ensure the safety of both employees and customers. The number of extinguishers should be determined based on the size and type of business and other safety measures. The extinguishers should also be regularly serviced and tested to ensure they are in good working condition.
