Select the right fire extinguisher for the type of fire you could face.

Macks Fire Protection's specialists can help you understand the type of fire extinguishers you need, or even if you need different types of extinguishers for separate locations in your facility.

Class A fires occur in common combustible materials such as paper, wood and cloth. A class A fire extinguisher uses water to cool and quench a fire.

Class B fires can break out in the vapor-air mixture over the surface of flammable liquids such as gasoline, grease and lubricating oils. These fires require an extinguisher with a smothering or combustion inhibiting agent such as dry chemical, foam, carbon dioxide, vaporizing liquids or water fog.

Class C fires occur in electrical equipment where it's dangerous to use anything other then non-conducting agents. A class C fire extinguisher uses dry chemical, carbon dioxide or vaporizing liquid. Water (except as a spray), foam and wand water-type extinguishing agents conduct electricity and can kill the operator of an extinguisher employing these agents, and severely damage electrical equipment.

Class A, B & C fire extinguishers: Since the combustible material that can fuel A, B & C fires can often be found near each other in the same building, fire extinguishers rated to fight any of these classes of fires are a common choice. These multipurpose dry chemical extinguishers are filled with monoammonium phosphate, a yellow powder that leaves a sticky residue that can damage electrical appliances such as a computer.

Class B &C fire extinguisher: These highly pressurized extinguishers shoot out carbon dioxide, a non-flammable gas. Unlike Class A, B & C multipurpose fire extinguishers, CO2 extinguishers don't leave a residue that's harmful to electrical devices. They aren't rated for Class A fires because of an inability to displace enough oxygen in a paper, wood or cloth fire to put it out or prevent it from reigniting.

Class K fires occur in cooking appliances in commercial kitchens that involve combustible cooking media (vegetable or animal oils and fats). Because of the volatility that can be present in commercial kitchens UL test requires the extinguishing system can completely extinguish a fire in a fryer and prevent the re-ignition of the vegetable oil for 20 minutes, or until the temperature drops to at least 60deg F (16degC) below the oil's auto-ignition temperature, whichever is longer.

Class D fires are fueled by combustible metals such as magnesium, titanium, zirconium and sodium. Only specialized techniques, extinguishing agents and extinguishing equipment developed for this class can be used to control and extinguish fires of this type. Do not use normal extinguishing agents on metal fires because they will increase the intensity of the fire due to a chemical reaction between burning metal and some extinguishing agents.
