Fire emergencies can occur without warning and can be deadly. It is thus very essential to be prepared for a fire emergency. One of the primary things that all individuals should know is how to use a fire extinguisher. A fire extinguisher is a great tool that will help you to fight small fires and limit their reach before they become too big and engulf the whole area. In addition, fire extinguishers are like the first line of defence and can be very efficient too. Therefore it is very important that you know exactly how to use a fire extinguisher.
Before using your fire extinguisher, be sure to read the instructions before it's too late. Although there are many different types of fire extinguishers, all of them operate in a similar manner.

A typical fire extinguisher contains 10 seconds of extinguishing power. This could be less if it has already been partially discharged. Always read the instructions that come with the fire extinguisher beforehand and become familiarized with its parts. It is highly recommended by fire prevention experts that you get hands-on training before operating a fire extinguisher. Most local fire departments offer this service.

Once the fire is out, don't walk away! Watch the area for a few minutes in case it re-ignites. Recharge the extinguisher immediately after use.

Use this acronym as a quick reference (it is a good idea to print this reference and pin it next to your fire extinguisher):

Pull the Pin at the top of the extinguisher. The pin releases a locking mechanism and will allow you to discharge the extinguisher.

Aim at the base of the fire, not the flames. This is important - in order to put out the fire, you must extinguish the fuel.

Squeeze the lever slowly. This will release the extinguishing agent in the extinguisher. If the handle is released, the discharge will stop.

Sweep from side to side. Using a sweeping motion, move the fire extinguisher back and forth until the fire is completely out. Operate the extinguisher from a safe distance, several feet away, and then move towards the fire once it starts to diminish. Be sure to read the instructions on your fire extinguisher - different fire extinguishers recommend operating them from different distances. Remember: Aim at the base of the fire, not at the flames.
These should be kept in mind before using a fire extinguisher. It is also important that you be careful while using a fire extinguisher and maintain a safe distance from the fire. You should also be able to assess the fire and the type of fire extinguisher to make sure the fire extinguisher will provide the reduction needed. Using this understanding of how to use a fire extinguisher, you can now be in a much better position to fight fires in case of an emergency.
