Fire safety is a paramount concern for businesses of all sizes. In the event of a fire, having the right fire extinguisher on hand can mean the difference between a minor incident and a catastrophic event. There are several types of fire extinguishers, each designed to combat specific classes of fires. In this guide, we’ll provide a brief overview of each type and explain why businesses may need a variety to ensure comprehensive fire protection.
Water-Based Fire Extinguishers (Class A)
Water-based fire extinguishers are suitable for Class A fires involving ordinary combustibles such as wood, paper, and fabric. They work by cooling and soaking the materials, reducing the temperature, and suppressing the fire. However, they should not be used on electrical or grease fires, as water can conduct electricity and may spread grease fires.
Businesses with a high risk of Class A fires, such as offices, schools, and retail spaces, benefit from water fire extinguishers. These extinguishers are cost-effective and environmentally friendly.
CO2 Fire Extinguishers (Class B and C)
Carbon dioxide (CO2) extinguishers are suitable for Class B (flammable liquids) and Class C (electrical) fires. They work by displacing oxygen, suffocating the fire. CO2 extinguishers are ideal for use on electrical equipment, as they leave no residue.
Businesses with electronic equipment, server rooms, and laboratories should have CO2 extinguishers on hand. These extinguishers are non-conductive, making them safe for use around electrical equipment.
Dry Chemical Fire Extinguishers (Class A, B, and C)
Dry chemical extinguishers are versatile and effective on Class A, B, and C fires. They contain a dry chemical powder that interrupts the chemical reactions of the fire, extinguishing it.
Ideal for businesses with mixed fire risks, dry chemical extinguishers are commonly found in manufacturing facilities, workshops, and warehouses. They are effective on a variety of fire types and provide a valuable all-in-one solution.
Foam Fire Extinguishers (Class A and B)
Foam extinguishers are designed for Class A and B fires. They create a barrier between the fuel and the oxygen, smothering the fire and preventing re-ignition.
Facilities dealing with flammable liquids, such as fuel storage areas and chemical processing plants, benefit from foam extinguishers. The foam provides an additional layer of suppression for liquid fires.
Wet Chemical Fire Extinguishers (Class K)
Wet chemical extinguishers are specifically designed for Class K fires, which involve cooking oils and fats. They work by creating a cooling effect and saponifying the fats, forming a blanket that prevents reignition.
Restaurants, commercial kitchens, and food processing facilities should have wet chemical extinguishers. They are crucial for safely extinguishing kitchen fires involving hot oils and fats.
