 In Electrical Fire Safety, Fire Extinguishers, Fire Safety, News

An essential part of any fire safety plan is knowing which fire extinguisher to use on the different kinds of fires.  Electrical, chemical, or flammable liquid fires are fought with different approaches and require specific types of extinguishers.  Class C fires are known as electrical fires and require a class C fire extinguisher to put out the fire.  When battling an electrical fire there are certain precautions that need to be taken.  Recognizing the specific qualities of class C fires and how to prevent and extinguish them is essential for keeping your commercial and residential properties safe.

What are Class C Fires?

A class C fire is fueled by a power source, such as a short circuit, faulty wiring, power cord damage, overloaded electrical outlets, or overcharged devices.  Anywhere electrical equipment is used, or wiring is present is a possible site for a class C fire. When a fire occurs in a power panel, computer, or kitchen appliance, the electricity powering the equipment is a constant source of spark or ignition.  Because water conducts electrical currents, using water and water-based foams can result in a spread of the electricity which is the fire’s source of ignition.

How to Fight a Class C Fire                         

A class C fire extinguisher is appropriate for smothering a fire connected to an electrical source.  If water is used on an electrical fire still connected to its power source, the person fighting the fire may be electrocuted.  A class C fire becomes a class A fire once the power source is disconnected.

Class C Fire Extinguishers

Class C fire extinguishers may contain carbon dioxide which smothers a fire by eliminating the oxygen and suppresses heat with its cold discharge.  They can also contain dry chemicals such as monoammonium phosphate, potassium bicarbonate, or potassium chloride to break apart the elements that feed a fire: oxygen, heat, and fuel.  It is possible to use a dry chemical fire extinguisher on class A, B and C fires.

It is important to have a fire extinguisher nearby any place where an electrical fire may occur.  Class C fires occur quickly and must be put out with equal speed. Knowing the proper way to fight this type of fire is important – it can save lives.  Call Fire Control Systems for all your fire safety needs.
