In the event of a fire, correctly using a portable fire extinguisher could mean the difference between suffering a minor loss or a major one. Portable fire extinguishers, when used properly,
can make that difference. But there are several important things to consider in using fire extinguishers.
First, you must know the class of fire involved and the correct type of fire extinguisher to use.
Class “A” Fires – involves ordinary combustibles such as paper, wood, cloth, rubber or plastics – use water or dry chemical extinguishers
Class “B” Fires – involves flammable liquids, grease or gases – use foam, carbon dioxide or dry chemical extinguishers
Class “C” Fires – involves live electrical fires – use CO2 or dry chemical extinguishers
Class “D” Fires – involves combustible metals such as magnesium and sodium – use special
extinguishing agents
RESPONDING TO FIRES:
Sound the fire alarm and call the local fire department immediately if a fire breaks out. Follow the company’s procedures on responding to a fire. Attempt to fight the fire only if, (1) you know the type of combustible material burning, (2) you have been trained to use the fire
extinguisher correctly, and (3) if the fire is still in the incipient (beginning) stage. If the fire gets too large or out of control, evacuate immediately and wait for the fire department.
“P-A-S-S” THE KEY TO EFFECTIVELY USING A FIRE EXTINGUISHER:
P……..Pull. Pull the locking pin before using the fire extinguisher.
A…….Aim. Aim the fire extinguisher at the base of the fire. Not at the flames or smoke.
S…….Squeeze. Squeeze the lever of the fire extinguisher to operate and discharge.
S…….Sweep. Sweep the fire extinguisher back and forth at the base of the fire to extinguish.
(Most extinguishers will only allow about 10-seconds of extinguishing media.)
Prevention is the key when it comes to firefighting. Good housekeeping, proper storage
procedures and safe work practices will go a long way toward reducing the likelihood that a fire will destroy valuable property or injure either you or fellow employees. Take a look around and think about what materials around your workspace present the greatest fire risk.
