A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire brigade. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent that can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common.
Why we use fire extinguisher?
Fire extinguisher, portable or movable apparatus used to put out a small fire by directing onto it a substance that cools the burning material, deprives the flame of oxygen, or interferes with the chemical reactions occurring in the flame.
How & When To Use A Fire Extinguisher?
- Most fires start small. If the fire is contained to a single object, such as a trash can, you may want to try using a fire extinguisher to put out the flames. Remember, you only have seconds – a fire burning for just l minute will have tripled its original size.
- You should only consider using a fire extinguisher if all members of your home have been alerted to the fire and the fire department has been called. Also, make sure you are safe from smoke and that the fire is not between you and your only escape route.
- When purchasing a fire extinguisher, look for one that is tested by an independent testing laboratory. Also, look for one labeled A-B-C as it can be used on most fires that would occur in your home. You want to be sure that the type of fire extinguisher you would be using would be effective at putting the fire out.
- Make sure you are physically able to handle a fire extinguisher. Some models are heavy and may be hard to operate and hold at the same time.
- Know how to operate the extinguisher quickly. You will not have time to read instructions during an emergency.
- Keep your fire extinguisher in an easily accessible area. Make sure it is not blocked by anything that would keep you from grabbing it quickly in an emergency.
