DCP FIRE EXTINGUISHER
Multipurpose ABE powder is a versatile extinguishant which is
used to extinguish Class A (carbonaceous) fires achieved by sealing burning
embers, it is also used on Class B (flammable liquid) fires and Class E
(electrical) fires. Dry
chemical powder is usually a mix of
monoammonium phosphate and ammonium sulfate, the former being the active one.
The mix between the two agents is usually 40–60%, 60-40%, or 90-10% depending
on local standards worldwide.
They are highly effective for electrical hazards. This multi-purpose
extinguisher interferes with the combustion process and provides rapid-fire
knockdown. They are ideal for mixed fire risk environments and especially
suited for protection for liquids, storage of liquid gases and heating oils
used for industry, garages, and workshops.
HOW DOES A DCP FIRE EXTINGUISHER WORK?
Dry chemical powder is
used on most classes of fires. Stops the chain reaction by smothering. Pressure
is generated by Gas cartridges stored inside the cylinder. Its force will last
for 2 minutes and can reach 10 – 15 feet. Extinguishers
put out fire by coating the fuel with a thin layer of dust, separating the fuel
from the oxygen in the air. The powder also works to interrupt the chemical
reaction of fire, so these extinguishers are extremely effective at putting out
fire.
DCP fire extinguisher has been found to be effective in initially ceasing
combustion of oils or fats, however re-application of additional dry chemical
may be necessary due to the potential for re-flash of oils or fats heated to
near or at their flash point.
Dry chemical is inappropriate for chlorine or oxidizer fires. The resulting
chemical reaction can cause an explosion or a breakdown of the chemicals
releasing toxic gases. Water should be used in that case.
WHAT FIRES CAN DRY CHEMICAL POWDER FIRE
EXTINGUISHERS BE USED ON?
As has already been
mentioned, dry chemical powder fire extinguishers and extremely effective and
versatile.
ABE Type:
·
Class A Fires – paper,
cardboard, wood, fabrics, people etc.
·
Class B Fires –
flammable liquid fires, petrol, diesel, oil etc.
·
Class E Fires –
electrical fires, computers, photocopiers, switchboards etc.
BE Type:
·
Class B Fires –
flammable liquid fires, petrol, diesel, oil etc.
·
Class E Fires – electrical
fires, computers, photocopiers, switchboards etc.
·
Class F Fires –
although not included in the rating the BE type is capable of extinguishing
cooking oil fires
Both types of dry
chemical powder fire extinguishers can be used on flammable gas fires, however
evaluate the situation carefully before doing this, as burning gas eliminates
the gas, whereas if the fire is extinguished, the gas can continue to leak,
build up and become a potential bomb if ignition is triggered.
ADVANTAGES OF DRY CHEMICAL FIRE EXTINGUISHERS
Dry Chemical Fire
Extinguishers can be used on a variety of different types of fire. So, it’s
relatively safer even in tricky circumstances such as electrical fires.
Extremely cost
effective compared to other types of fire extinguishers. They come in various
sizes and can also be stored easily in normal home/office settings. These
powder fire extinguishers are able to cover large areas, thus providing more
protection.
Dry Chemical fire
extinguishers also act as remarkable heat shields. The discharge of the dry
powder acts as a shield against radiated heat. If a large quantity of powder
has been released, it also has the ability to shield and protect surrounding
objects and structures from the damage of fire.
DISADVANTAGES OF DRY
CHEMICAL FIRE EXTINGUISHERS
Cleaning up after use
can be a chore because of the mess created by the powders in the process of
extinguishing the fire. Visibility can be reduced by a great deal while using
this extinguisher. This could hinder in finding the exits and accurately aiming
at the fire.
Breathing in the
chemicals in these extinguishers for a long period can be dangerous. While
these ABE fire extinguishers are versatile, they still have some limitations
and will not work against Class C and Class D fires.
HOW TO USE DRY CHEMICAL FIRE
EXTINGUISHERS?
The working process of
these fire extinguishers is the same as any other extinguishers on the market.
You just need to follow the PASS technique.
• Pull the Pin
• Aim it at the fire.
• Squeeze the handle.
• Sweep from side to side.
