The
Importance of Pressure
Think of what happens when you shake up a
bottle of soda then open the cap. The pressure inside the bottle pushes the
soda out. The same idea applies to a fire extinguisher. The contents in a
fire extinguisher are pressurized, so when you squeeze the trigger, the
pressure expels the fire-fighting agent. Without enough pressure the fire
extinguisher cannot work properly in an emergency.
Here
is the right way to check the pressure on your Fire Extinguisher:
-
Make sure the arrow is pointing anywhere in the area
marked "FULL."
-
Press the green button on the top of
the fire extinguisher. If it pops back up your fire extinguisher has
adequate pressure.
Non-rechargeable fire extinguishers are intended for one use only. If you
use your fire extinguisher even once, you must replace it. It will not be
effective in fighting a fire.
