Why foam for flammable liquids
Water sinks under burning petrol, diesel or solvents and can spread the fire. Foam floats on the liquid, smothers the flames, cools the surface and seals in the vapours so the fire does not flash back.
Low, medium or high expansion
- Low expansion foam through monitors and branch pipes for tanks, bunds and loading bays.
- Medium expansion for spill areas and smaller rooms, using a medium expansion foam generator.
- High expansion to fill large volumes such as warehouses and hangars, using a high expansion foam generator.
For smaller risks, a mobile foam unit or a foam monitor on the hydrant line may be enough. See all foam equipment and water and foam monitors.
