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