Why choose the powder extinguisher polyvalente ?
The need to install a fire extinguisher in the house is not a legal requirement. This limits the risk of fire, because this equipment can stop a fire from starting. The choice of extinguishing agent is essential if you want the fire equipment to be effective. For a home extinguisher, professionals generally recommend multi-purpose powder. Find out why?
Characteristics of the multi-purpose powder extinguishing device
The technical and chemical characteristics of themulti-purpose powder extinguishing device make it accessible to everyone.
The chemical composition of a multi-purpose powder
Also known as Blue Powder, the multi-purpose powder contains Ammonium Phosphate or Ammonium Sulphate as well as Monoammonium Carbonate or Phosphate or Sodium Bicarbonate.
In contact with fire, Ammonia decomposes on the embers and forms a glassy impermeable layer. This allows it to quickly smother the fire and stop the fire from starting. Ammonium salts have the ability to separate the fuels responsible for the fire. Under the effect of heat, they melt to insulate the combustibles and stop the spread of the fire.
Sometimes the multi-purpose powder contains Potassium Aluminum Silicate or Magnesium Aluminum Silicate. The aim is to ensure that the powder remains firm during launch. Manufacturers may also add silicone oil to prevent the product from piling up and losing its effectiveness due to moisture.
Different capacities of multi-purpose powder extinguishers
For domestic use, an extinguishing device of 1 to 3 kg is sufficient to limit the risk of fire propagation. However, manufacturers are offering models with larger volumes to meet consumer needs. For example, you can find multi-purpose powder extinguishing units with a capacity of 11 kg or 17 kg total weight. This will give you a fire equipment containing 6 kg or 9 kg of powder respectively.
Advantages of the versatile powder fire extinguishing agent
The multi-purpose powder extinguisher has the advantage of fighting fires of different categories. Indeed, it is effective in containing the onset of a fire generated by class A, B and C fires.
As a reminder, Class A fires are also known as solid fires. They are generated by solid fuels such as paper, cardboard or fabric. Fires of liquids and liquefiable solids, i.e. Class B fires, can be caused by paints, hydrocarbons, etc. Class C fires are caused by gaseous fuels.
Note that the multi-purpose powder extinguisher can also be used on fires generated by electrical equipment. There is no risk of causing short circuits.
How to use a dry chemical fire extinguisher polyvalente ?
The multi-purpose powder extinguisher is easy to use. Simply remove the safety pin and depress the control lever and then the lance trigger. Try to aim the flame at the flame from a safe distance.
It is important to note that the multi-purpose dry chemical fire extinguisher acts on the fire through insulation, but cannot cool it down. For this reason, it is necessary to take all necessary precautions to avoid the risk of burns.
