Fire Extinguisher Requirements For Commercial Buildings

No matter whether your business is an office, a restaurant, a shopping mall or a factory, you must comply with national or local fire safety regulations. The core requirements include:

Matching the type of fire extinguisher to the fire risk

Class A fire (paper, wood, fabric): usually water-based or ABC dry powder
Class B fire (oil products, flammable liquids): recommend foam or carbon dioxide
Class C fire (electrical equipment): carbon dioxide or ABC dry powder
Class K fire (kitchen vegetable oil fire): must use Class K fire extinguisher

Reasonable quantity and coverage

Common regulations: the distance from any point in the building to the nearest fire extinguisher ≤ 23 – 30 meters
High-risk areas need to increase fire extinguishers or choose larger capacity models

Correct installation location

The bottom edge of the fire extinguisher is about 80 – 120 centimeters from the ground
Install it in a prominent, unobstructed area, away from heat sources

Regular inspection and maintenance

Monthly self-check of pressure gauge, safety pin, appearance
Every year, have it inspected by a professional institution
Conduct water pressure tests of 5 – 12 years at different intervals according to the model

What Size Fire Extinguisher For Business

The most common question that enterprises ask is: How large should we choose the fire extinguisher?

Example of recommended specifications for common business scenarios:

Scene	Recommended model	Type of Recommendation
Small office(<100㎡)	2.5–5 Pound	ABC Dry Chemical Powder
Medium-sized commercial stores / restaurants(100–300㎡)	5–10 Pound	ABCDry Chemical Powder or Class K
Warehouse / Factory(>500㎡)	10–20 Pound	ABCDry Chemical Powder/Foam/CO2

Size and capacity impact:

The larger the capacity, the longer the spraying time and the stronger the fire extinguishing effect
Fire extinguishers that are too heavy (20 pounds ≈ 9 kg) may be too heavy for employees to carry
Smaller fire extinguishers have shorter spraying time and limited applicable area

Safety-Plus suggests: First, select the capacity based on the risk level and area of the place, and then decide whether to use a smaller model based on the position to facilitate quick operation by employees.
