The How to's on using a fire extinguisher
A portable fire extinguisher can be a life and property saving tool when used correctly. In order to operate an extinguisher, the National Fire Association suggests remembering the word PASS:
Pull the pin. Hold the nozzle pointing away from you and release the locking mechanism.
Aim low. Point the extinguisher at the base of the fire.
Squeeze the lever slowly and evenly.
Sweep the nozzle from side-to-side.
Read the instructions on the fire extinguisher and become familiar with them before a fire breaks out. Remember, extinguishers do have limitations. It is also important to ensure you have the correct type of extinguisher for your facility.
