In stored pressure models the expellant gas and extinguishing agent are stored in a single chamber and discharge is directly controlled by the valve
These units have the advantage of being easily inspected since most are equipped with a pressure gauge indicating that the unit is ready for use.
Once used this unit requires special recharging equipment and is normally returned to the fire department for recharge
With cartridge operated fire extinguishers, the expellant gas is stored in a separate cartridge located within or adjacent to the shell containing the extinguishing agent
Sealed pressure fire
extinguishers are much the
same as stored pressure units
and are often referred to as
Sealed pressure - cont.
The expellant gas and
extinguishing agent are both
stored in a single chamber,
but differ from stored
pressure units in that sealing
is accomplished by means of
a frangible metal disc as
opposed to a valve
Wheeled units are also
extinguishers and are
nitrogen cylinder operated
dry chemical units. They are
available in sizes ranging
from 75 pounds to 350
pounds. They can be used on
Class A, B and C fires
depending on the agent used.
Portable fire extinguishers must be visually inspected monthly. The inspection should assure that:
1. Fire extinguishers are in their assigned place;
2. Fire extinguishers are not blocked or hidden;
3. Fire extinguishers are mounted in accordance with NFPA Standard No. 10 (Portable Fire Extinguisher);
4. Pressure gauges show adequate pressure (CO2 extinguisher must be weighted to determine if leakage has occurred);
5. Pin and seals are in place;
6. Fire extinguishers show no visual sign of damage or abuse;
7. Nozzles are free of blockage.
Extinguisher Placement (Travel Distance)
The following chart contains OSHA requirements for classes of fires and
travel distance to an extinguisher.
Some local requirements may be stricter, so you should always check with your local fire marshal / fire prevention office.
“P” for PULL
“A” for AIM
"S“ for SQUEEZE
“S” for SWEEP
The average hand portable extinguisher will only operate for 30 seconds ----- There is NO TIME to learn during an actual emergency.
IN CASE OF FIRE
Evacuate the building
Call the fire department
Make sure the fire is small
Make sure you have a clear way out
