If you’re in the market for a new fire extinguisher for your
business, be sure to do your research before scouring Mississauga stores for
the right fire
The Fire Classifications
Different fire extinguishers are designed to fight different
types of fires
. Before you step out the
door, it’s important to look at what’s in the building. Once you know what has
the potential to start a fire or catch on fire, you can focus on which fire
extinguisher is right for your Mississauga business.
Fires are assigned a letter, from A to D, depending on what
is on fire.
A class A fire involves ordinary combustible material that
can be found in almost all businesses throughout Mississauga. Wood, clothes,
upholstery, and garbage can all be found in this category. Such a fire can be
fought with water, chemical foam, or dry chemical powder fire extinguishers.
Flammable liquids are class B fires. This involves liquids
like oils, gasoline, or paint. Class B fires need a dry chemical, halon,
aqueous film forming foam (AFFF), or carbon dioxide fire extinguisher.
Class C fires include electrical fires. These fires are
normally caused by electrical equipment. Dry chemicals, halon, and carbon
dioxide are usually used to put out class C fires.
Combustible metals cause class D fires. These metals, such
as magnesium, need to be put out with a dry powder formulated for the specific
metal involved. Businesses that store combustible metals should consult a professional
fire protection technician
. It’s important to ensure that the right
material is onsite.
Picking Your Fire

normally enough. These fire extinguishers are readily available across
Mississauga and smother the flames of class A, B, and C fires with pressurized
A pressurized water fire extinguisher is a good choice for
situations that could potentially involve a class A fire. A water extinguisher
must never be used on a class B or C fire. Always place it away from flammable
liquids and electrical equipment to avoid personal injury and increasing the
spread of the fire.
Both class A and B fires can be smothered by an AFFF
chemical foam fire extinguisher, making it a good choice for kitchens, as long
as you avoid appliances.
Compressed gas fire extinguishers, containing carbon dioxide
or halon, also smother flames. Pick this type of fire extinguisher if you are
dealing with class B (flammable liquids) or class C (electrical equipment)
No matter what kind of fire extinguisher you choose, it’s
important to perform monthly maintenance checks. The pressure gauge should
always be in the green zone. If the needle has drifted into the red zone on
either side of the green, it’s time to have the fire extinguisher replaced or
Before purchasing a fire extinguisher for your Mississauga restaurant
or other business, familiarize yourself with the different types of fire
extinguishers available and know the types of potential fires in your building.
