All about Foam Fire extinguishers

Foam fire extinguishers can blow out both solid and liquid fires, such as those brought on by burning gasoline or solid fires like those started by burning wood. The flaming liquid or burning objects like couches may be covered by the foam, which could also soak into them. While the foam itself keeps oxygen from reaching the flames, the water that is held within it aids in putting out the fire. Foam extinguishers are strongly advised for use in both homes and workplaces.

Despite this, considerable caution must be used while disposing of foam extinguishers or cleaning up after a foam discharge. This is due to the fact that AFFF foam is potentially carcinogenic and can contaminate surface waters like rivers. To ensure proper recycling, always make sure the fire extinguishers are handed off to another person. The fire extinguisher servicing engineer will typically remove and dispose of your old extinguishers for a small cost.

How to use a mechanical foam fire extinguisher?

Mechanical foam fire extinguishers can be used to put out flames that are either class A or class B, however how they are administered changes depending on which type of fire they are meant to put out. 

Only small fires should be put out with extinguishers. Instead of attempting to put out a fire that has already spread, you should leave the area right away, alert people to the emergency, and then dial the fire and rescue department. Keep a safe distance and adhere to the instructions listed below if you want to attempt to put out the fire.

The tamper seal will be broken if you remove the safety pin.

Squeeze the lever to start the extinguisher's discharge process.

Standard Fire Solution offers a range of delivery and suction couplings, accessories and adaptors as per the requirement of industrial pipelines and hose.

The fire extinguisher's nozzle should be in the following position:

Flammable liquids: Instead of spraying directly at the flames, aim the hose at a vertical surface close to the fire. Spraying directly towards the flames could cause the liquid to splatter and start a fire, which would then spread to nearby areas. Foam extinguishers function by coating the surface of the flammable liquid with foam, which prevents oxygen from reaching the fire and lowers the liquid's temperature.

Fires brought on by electricity: If the foam extinguisher has been tested to withstand 35,000 volts, you may use it to put out active electrical fires (35kV). Nevertheless, keep a one-meter safe separation at all times.

Combustible solids: Move the nozzle around the area where the fire is burning while aiming it at the fire's base.

To help prevent the fire from re-igniting, the foam will act as a blanket over it and smother it, so make sure the fire has been entirely extinguished.
