Commercial Fire Extinguishers

Appropriate portable fire extinguishers properly installed in prominent, easily accessible locations are a common response to a sudden fire.

Fire Extinguisher Systems

Portable fire extinguishers are often the best solution for putting out a fire. According to the National Fire Protection Association (NFPA), more than 90 percent of fires are successfully extinguished when a portable fire extinguisher is used in the first two minutes.

Know What Kinds of Fire Your Business Can Expect

Fires are classified by the types of fuel that drive them, and fire extinguishers contain chemical agents that are effective against one or more classes of fire. An “AB” extinguisher, for example, can be used on a Class A or Class B fire.

Class A Fires

Ordinary combustible materials, such as paper, wood, or fabric.

Class B Fires

Flammable liquids, such as fuel, oil, alcohol, solvents, and other chemicals.

Class C Fires

Powered electrical equipment, such as computer servers and power infrastructure.

Class D Fires

Combustible metals, such as magnesium, sodium, and lithium.

Class K Fires

Kitchens and cooking appliances with combustible fluids, such as animal or vegetable oils.

Choose the Right Fire Extinguishers for Your Business

Different kinds of fires require different kinds of fire extinguishers—using the wrong type of extinguisher can make the situation worse. Following NFPA 10 standards for portable fire extinguishers, our experienced fire safety professionals can help you identify risks in your facility, choose the right extinguishers for each area, and install them in appropriate positions where they can be located easily and deployed quickly in an emergency. The NFPA recommends placing one fire extinguisher every 50 feet in a commercial building.

Water-based fire extinguishers are intended primarily for Class A fires. Most release a water mist or spray rather than a solid stream. Some may include additives to increase their effectiveness, or antifreeze to preserve functionality in freezing temperatures.


Aqueous film-forming foam (AFFF) extinguishers smother fires in foam. These are intended for Class A and Class B fires.

Carbon Dioxide

Carbon dioxide (CO2) extinguishers deprive fires of oxygen without leaving any residue, which can be a significant advantage in clean rooms, laboratories, and food preparation areas. Recommended for Class B and Class C fires indoors.

Halon Gas

Halon fire extinguishers displace oxygen in a manner similar to carbon dioxide extinguishers, but they have superior range and effectiveness. Halon extinguishers are recommended for Class A, Class B, and Class C fires.

Dry Chemical

Chemical fire extinguishers disperse a dry powder, such as sodium bicarbonate or potassium bicarbonate, suitable for Class A and Class B fires. Some dry powder extinguishers are specifically formulated for Class D fires.

Wet Chemical

Wet chemical extinguishers are water-and-chemical solutions usually meant for Class A and Class K fires.

Multiple Fire Extinguisher Options

Commercial fire extinguishers help protect mid-size and larger facilities across a wide range of industries. Ask our suppression and fire safety professionals to recommend an extinguisher solution based on your facility’s needs.
