In order to understand how fire extinguishers work, you first need to know a little bit about fire.
Not all fuels are the same, and if you use the wrong type of fire extinguisher on the wrong type of fuel, you can, in fact, make matters worse. It is therefore very important to understand the four different classifications of fuel.
Different types of fire extinguishers are designed to fight different classes of fire.
Fires can be very dangerous and you should always be certain that you will not endanger yourself or others when attempting to put out a fire.
It's easy to remember how to use a fire extinguisher if you can remember the acronym PASS, which stands for Pull, Aim, Squeeze, and Sweep.
