AFFF 6% foam 200L bulk
200 litre drum of AFFF 6% foam concentrate.

Foam is the primary fire-extinguishing agent for areas where flammable liquids and hydrocarbons, are transported, processed, stored, or used as an energy source.

AFFF (Aqueous film forming foam) can extinguish a flammable or combustible liquid fire by the combined mechanisms of cooling, separating the flame source from the fuel, suppressing vapors, and smothering. It can also secure against re-flash or reignition.

Foam is made up of three ingredients - water, foam concentrate and air. When mixed in the correct proportions, these three ingredients form a homogeneous "blanket" of small air-filled bubbles, which have a lower density than oil, petrol or water.

Water is heavier than most hydrocarbon fuels and if applied on its own, directly to the fuel surface, will sink to the bottom having little or no effect on extinguishing the fire, or suppressing vapor. Worse still, the water may boil below the fuel surface, throwing the fuel about, and spreading the fire.

The 3% foam is twice as concentrated as a 6% foam concentrate. Which is why it is more expensive. This sounds illogical, but the 3% refers to how much foam concentrate is required to make up a fire fighting foam. Eg for 100 litres of ready-to-use foam, you only need 3 litres of the 3% (and 97 litres of water), whereas you'd need 6 litres of the 6% foam concentrate (and 94L of water) to get the same result.

Additional freight costs apply to this product because of its weight.

Also available in 20 litre drums
