Foam Trolley Type Fire Extinguishers (25LTR, 50LTR)
A fire extinguisher is vital to fire safety equipment that helps save lives and damage. We all have seen them hanging in the walls at various places, but hardly any of us know how they work and what their types are.

The central container of the unit has a plunger mechanism and at the top of which when is depressed releases the carbon dioxide inside, allowing the foam and the water to mix. The foam, mixed with water comes out of the nozzle, making mechanical foam.
- Class A Fire: Wood, Textiles, Paper, Clothes, Cotton mill, Jute Mill etc.
- Class B Fire: Petroleum, Oil, Paint, Varnish, Solvent, Aviation Fuel, Flammable and Volatile Liquids etc.
- Note: Do not use on energized Electrical Equipment fires.
Foam extinguishers are not suitable for electrical fires as the foam can conduct electricity, leading to a risk of electrocution. Monitor the area after the fire is out to ensure there are no hotspots or re-ignition. When using on liquid fires, be careful not to disrupt the surface of the liquid as this could spread the fire. Ensure users are trained in the proper use of foam extinguishers and are aware of their limitations. Regularly check that the extinguisher is in good working order and that the pressure gauge is within the green zone.
Foam extinguishers are effective on both Class A (ordinary combustibles like wood, paper, and fabric) and Class B (flammable liquids like petrol, oils, and solvents) fires, making them versatile for different types of fire hazards.
Remove the safety pin to break the tamper seal. Aim the nozzle at the base of the fire. For liquid fires, it’s crucial to not aim directly at the surface as this could splash the liquid and spread the fire. Squeeze the handle to release the foam. Sweep the nozzle from side to side, covering the base of the fire completely. Continue until the fire is fully extinguished and be ready to apply more foam if the fire reignites.
