When it comes to installing portable fire extinguishers in your business, you have many factors to consider, including what type you need and where to install each canister. ABC fire extinguishers, which are the most common type, are effective against Class A (ordinary fires), Class B (flammable fuel fires), and Class C (electrical fires). Class D fire extinguishers are needed in industrial facilities where ignitable metals are present, and Class K extinguishers are required to fight grease fires in commercial kitchens. The minimum walking distance between fire extinguishers depends on the fire threat level in your business.
In addition to choosing the right type and installing your fire extinguishers correctly, you also need to consider fire extinguisher capacity. Here’s a concise guide to help you size a fire extinguisher correctly.
Learn How to Read the Label
Portable fire extinguishers are rated for the size of fire they can put out. For Class A fire extinguishers, this number ranges from 1 to 40, and for Class B, the rating is from 1 to 640. You can find this rating on the label.
2A:10B:C is the label you’ll find on a standard 5-lb ABC fire extinguisher. Note that the Class C rating isn’t accompanied by a number. The letter simply indicates that the extinguisher is rated to put out electrical fires.
Consider the Size of the Room
For a room of average dimension, a 5-lb fire extinguisher may be sufficient. For larger commercial spaces and warehouses where a fire has more room to spread, a larger 10-lb model may be necessary.
Think About the Physical Capabilities of Your Employees
Most people have no difficulty lifting and operating a 5-lb-capacity fire extinguisher. However, the 10-lb model may be difficult for some. If you feel you need the firefighting power of a larger canister, but you’re worried about the greater weight, consider installing two smaller extinguishers side by side. Then the second canister can be used in a fire emergency if one isn’t enough to douse the blaze.

The article rightly emphasizes the importance of choosing the appropriate type of fire extinguisher for a given setting. ABC fire extinguishers, as the most common type, are versatile and effective against ordinary fires (Class A), flammable fuel fires (Class B), and electrical fires (Class C). In industrial facilities with ignitable metals, the article rightly points out the necessity of Class D fire extinguishers. Additionally, the mention of Class K extinguishers for combating grease fires in commercial kitchens underscores the specificity required in certain environments.
The concept of minimum walking distance between fire extinguishers based on the fire threat level in a business is crucial and aligns with established safety standards. This factor ensures that extinguishers are strategically placed, minimizing response time during emergencies.
The article rightly extends its focus to the consideration of fire extinguisher capacity. Understanding how to read the label, with the rating system for Class A and Class B fires, is a fundamental aspect. The example of a 5-lb ABC fire extinguisher labeled as 2A:10B:C provides clarity on interpreting these ratings. Furthermore, the advice on adjusting the size of extinguishers based on room dimensions and the physical capabilities of employees demonstrates a nuanced approach to fire safety.
The suggestion to install two smaller extinguishers side by side, if the need for a larger canister is identified, reflects a practical solution to address both firefighting effectiveness and ease of use. This recommendation showcases a deep understanding of the practical challenges faced by businesses in ensuring fire safety.
In conclusion, the article provides a concise guide for sizing fire extinguishers correctly, covering essential concepts such as type selection, installation considerations, and capacity adjustments.

Fire extinguishers should be placed every 30 to 50 feet from each other. Extra Fire Hazard: An extra hazard building has a greater-than-ordinary level of fire hazard and requires larger extinguishers to be placed every 30 to 50 feet from each other, depending on location.
For a room of average dimension, a 5-lb fire extinguisher may be sufficient. For larger commercial spaces and warehouses where a fire has more room to spread, a larger 10-lb model may be necessary.
The fire rating is found by multiplying the floor area in metres squared (m²) by 0.065. Therefore for a floor area of 200m² the fire rating is 200 x 0.065 = 13A. A 9 litre water extinguisher has a fire rating of 13A, therefore one 9 litre water extinguisher will be required for every 200m² of floor area.
“A fire extinguisher, rated not less than 2A, shall be provided for each 3,000 square feet of the protected building area, or a major fraction thereof. Travel distance from any point of the protected area to the nearest fire extinguisher shall not exceed 100 feet.”
A fire extinguisher, rated not less than 2A, shall be provided for each 3,000 square feet of the protected building area, or major fraction thereof. Travel distance from any point of the protected area to the nearest fire extinguisher shall not exceed 100 feet.
If there are Class A hazards, the commercial fire extinguishers must be at least 2A in size, with a distance of up to 75 feet between each device. For Class B hazards, you must have 10B commercial fire extinguishers positioned with 50 feet or less between each one.
Weight: 20 Pounds. Classification: 10A:120B:C. Good for: Sizable fires of standard types. This extinguisher provides the firefighting power of 12.5 gallons against fires in ordinary combustibles and 120 square feet of firefighting power against flammable liquids and gasses. It can safely fight Class C electrical fires.
All premises with electrical equipment must have at least 2kg CO2 extinguishers. Where there is 415 volt rated equipment, then 5kg CO2 extinguishers are required.
94% of the time a portable fire extinguisher is used, it puts out the fire - typically within the initial two minutes. 37% of the fire extinguishers used are dry chemical extinguishers. 27% of the fire extinguishers used are CO2 extinguishers. 20% of the fire extinguishers used are water extinguishers.
Example: A Fire Extinguisher with a rating of 5B:C would be able to extinguish 5 square feet of a class B fire and could also be used on a Class C fire (electrical- anything plugged in) due to it's non-conductive properties.
For Class A hazards, each extinguisher must be 2A or larger with a maximum travel distance of 75 feet between extinguishers. If Class B hazards are present, 10B extinguishers should be positioned so the travel distance for an occupant to reach any extinguisher is 50 feet or less.
Starting a fire extinguisher business can prove to be a lucrative small business opportunity. This is especially true in areas where there are a lot of commercial and residential buildings. If you establish a loyal customer base you can also make money through services such as recharging fire extinguishers.
To prevent fire extinguishers from being moved or damaged, they should be mounted on brackets or in wall cabinets with their carrying handles placed 3-1/2 to 5 feet above the floor, depending on the type of extinguisher.
If your business is spread over several floors there should be at least two fire extinguishers per level. However, if the floor is less than 100m2 in area, then one is acceptable. If an automatic fire suppression system is fitted, you may reduce the number of extinguishers provided.
There should be a minimum of 2 extinguishers per floor unless the upper floor area is very small, i.e. below 100m2, and in single occupancy, in which case, only one extinguisher is required on the upper floor.
As a basic rule of thumb, the floor area in square metres should be divided by 200 and rounded up to calculate how many nine-litre water or equivalent extinguishers are necessary. If there is a sprinkler or automatic suppression system in place, fewer fire extinguishers may be required.
The National Fire Protection Association (NFPA) recommends that locations such as offices, classrooms, and assembly halls that contain mainly Class A combustible materials have one 2-A extinguisher for every 3,000 square feet. [Standard for Portable Fire Extinguishers (NFPA 10 (2010), Table 6.2.
