Safety Tips: Portable Fire Extinguishers

This is a brief overview of the important points of using a portable fire extinguisher. Fire can be devastating, but when used properly, a fire extinguisher can save lives and property.

FIRE

Fire is the process that occurs when heat, fuel, and oxygen join together, either by chemical chain reaction, Nature or by human intervention. Fire extinguishers work by removing one of these items. Fire can be prevented by keeping these items away from each other.

TYPES OF FIRE

There are three common types or classes of fire:

class "A" type fires involve ordinary combustibles such as: wood, paper, cloth, rubber, and many plastics.

class "B" type fires involve flammable liquids such as: gasoline, oil, grease, tar, oil-based paints, lacquer, and flammable gases.

class "C" type fires involve energized electrical equipment such as: wiring, fuse boxes, circuit breakers, machinery, and appliances.

Fire extinguishers are tested to determine what class of fire they are suitable for. Fire extinguishers will be marked as to which fires they may or may not be used on. Make sure the fire extinguisher you select is rated for the class of fire you intend to fight.

IN CASE OF FIRE

• Evacuate the building
• Call the fire department
• Make sure the fire is small
• Make sure you have a clear way out
• Make sure the fire extinguisher is rated for the type of fire and that you know how to use the extinguisher.
• Start as far away from the fire as possible
• Always back away from the fire even if it appears to be out.
• It is reckless to fight the fire if these conditions do not exist, instead leave the building closing the doors behind you to slow the spreading of the fire and smoke
