There are four classes of fire, Class A, B, C, and K.
The four elements that must be present for fire to exist include heat, oxygen, fuel, and a chemical reaction between the three.
Class B fires are those fires that occur involving paper and wood.
Multipurpose dry chemical extinguishers are effective on all classes except D and K fires.
The four simple steps for operating a fire extinguisher can be remembered with the word PASS. Pull, Activate, Squeeze, Sweep.
According to local, state and national codes and regulations, fire extinguishers must be maintained bi-annually.
Fire extinguishers must be inspected or checked every 60 days.
The concept of fire prevention is to keep these elements separate.
To remember the rules of fighting fires, just remember the three A's: Activate, Assist, and Attempt.
After the fire has been extinguished, it is important to watch the site for re-ignition.
