Maintain your foam fire extinguisher

Annual maintenance should be conducted by a qualified technician and should include a full inspection, pressure testing, and refilling the extinguisher if necessary.

The chemicals inside a foam fire extinguisher are a mixture of water, foam concentrate, and pressurized air or nitrogen. The foam concentrate is a mixture of water and a foaming agent, such as synthetic detergents or protein-based materials. When released from the extinguisher, the foam expands and blankets the fuel, smothering the fire and preventing it from reigniting.

In conclusion, foam fire extinguishers are a valuable tool for fighting fires involving flammable liquids and solid combustibles. Proper use, maintenance, and inspection are necessary to ensure the extinguisher is ready and effective in the event of a fire. The chemicals inside the extinguisher are a mixture of water, foam concentrate, and pressurized air or nitrogen, which work together to smother the fire and prevent it from reigniting.
