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. The following tips are suggested guidelines.

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 elements. Keeping these items away from each other can prevent fire.

Types of fire
There are three common types or classes of fire:
Class A - Involves ordinary combustibles such as wood, paper, cloth, rubber and many plastics.
Class B - Involve flammable liquids, such as gasoline, oil, grease, tar, oil-based paints, lacquer and flammable gases.
Class C - 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.

Using a fire extinguisher
This four step method known as PASS is used for operating most common fire extinguishers:
P Stands for PULL the pin. This will unlock the operating handle and allow you to discharge the extinguisher.
A Stands for AIM at the base of the fire.
S Stands for SQUEEZE the operating handle. This will discharge the fire fighting agent.
S Stands for SWEEP from side to side. Move carefully in on the fire, aiming at the base, sweep back and forth.

Discovering a fire

• Activate the nearest Fire Alarm Call point (break glass) if one is installed

• Call the Fire Brigade

• Attack the fire if possible using the correct appliance provided

• Start as far away as possible

• Always back away from the fire - even if it appears to be out
  
  

Hearing the fire alarm

Evacuate the building and do not stop to collect belongings. Ensuring that you shut doors behind you will help stop the spread of fire and smoke.  Once you are out of the building you must report to the designated assembly point.
