AA Fire Extinguisher

Our company has become a leader of fire extinguisher service in Dallas, Rockwall, Mesquite and Garland, with its headquarters located in Carrollton.  This is our About Us page.

Fire extinguishers are special pressurized devices that release chemicals or water to put out a fire.
They keep small fires from spreading, assist in fighting fires until the fire department arrives and can help provide an escape route for you and your family.
 
Portable Fire Extinguishers
Portable fire fighting equipment is designed to provide the user with an appliance to attend a small fire during its initial stage. When deciding to attack a fire, always designate another person to raise the alarm and obtain a back-up fire extinguisher. Portable fire extinguishers should be provided in all buildings.
Fire Extinguisher Classes

Types/Selection of fire extinguishers

There are a number of types of portable fire extinguishers available in Australia. Each type of extinguisher may be rated for one or more classes of fire. In some cases, particular extinguishers are not only considered ineffective against certain classes of fire, they can be dangerous in those circumstances. The Classes of fire are:
CLASS A  Paper, Wood, Cardboard
CLASS B  Solvents, Paint, Petroleum, Methylated Spirits
CLASS C  Flamable Gases
CLASS D  Combustible Metals
CLASS E  Electrical
CLASS F  Cooking Oils and Fats
There are three essential elements involved in producing fire — heat, oxygen and fuel. To put a fire out, you need to effectively remove one of these elements.

The best way to remove heat is to dump water on the fire. This cools the fuel to below the ignition point, interrupting the combustion cycle.

To remove oxygen, you can smother the fire so it is not exposed to air. One way to smother a small fire is to cover it with a heavy blanket

Removing the fuel is the most difficult approach for most fires. In a house fire, for example, the house itself is potential fuel. The fuel will only be removed once the fire has burned all of it up.
Fire extinguishers are sturdy metal cylinders filled with water or a smothering material. When you depress a lever at the top of the cylinder, the material is expelled by high pressure, similar to the way material is forced out of an aerosol can.
A siphon tube leads from the bottom of the fire-suppressant reservoir to the top of the extinguisher. A spring-mounted valve blocks the passageway from the siphon to the nozzle. At the top of the cylinder, there is a smaller cylinder filled with a compressed gas — liquid carbon dioxide, for example. A release valve keeps the compressed gas from escaping. In Australia, we have Stored Pressure Extinguishers.
