Firefighting Applications

GreenFire Firefighting Foam (GFFF) can be used for:

    • Petroleum or Alcohol-based fires
    • Aircraft hangars
    • Fuel storage
    • Mechanical bays
    • Equipment

Recommended Applications

The 0.1% – 3% can be used with conventional foam equipment with fresh, sea or brackish water.

Self inducting foam nozzles and foam nozzles with in-line inductors are among the most common types of hardware for application.

In addition to its use in aspirating foam equipment, it can be dispensed effectively through non-aspirating equipment Including fog nozzles, water spray devices and standard sprinklers.

Is effective in sub surface injection systems for non-water-soluble hydrocarbons. Sub surface injection is safe and reliable for fixed protection of storage tanks.

GreenFire Firefighting Foam (GFFF) may be applied to tires simultaneously with dry chemical firefighting agents because the two are compatible.


GreenFire Firefighting Foam (GFFF) does NOT have a positive spreading coefficient and is therefore NOT considered an AFFF type foam.

However, its ability to form a stable foam blanked covering a fuel surface allows it to be used effectively in many applications where AFFF foams have previously been the standard.

Positive fire suppression and vapor control.

Proportions Readily: Permits use in a wide range or proportioning equipment.

Solution Stability: Solutions of  GreenFire Firefighting Foam (GFFF) do not present “transit time” limitations through handlines or in fixed systems.
