Aberdeen Foam 6% AFFF-LF concentrate provides quality protection wherever hydrocarbons present a fire risk:

  • Offshore platforms and helidecks
  • Petrochemical refining, processing and storage facilities
  • Marine terminals, power stations and road / rail loading racks
  • Rapid Intervention Vehicles and aircraft hangar systems

Produced AFFF-LF foams can also be used as wetting agents for combating Class A fires (i.e.tyres, paper, wood) and for providing a vapour suppression blanket on hydrocarbon spills.

Storage & shelf life

Best stored as supplied in original, unopened containers. Suitable for storage in containers and tanks manufactured from:

  • Stainless steel (Type 304L or 316L)
  • High density cross-linked polyethylene
  • FRP (vinyl ester epoxy resin only)

Aberdeen Foam 6% AFFF-LF concentrate is designed for use in cold climates and has low minimum use and storage temperatures.

If kept in the original manufacturer’s supplied container and stored between -17.8°C and 49°C, a shelf life of at least 10 years can be expected.

To prolong the shelf life of any AFFF-LF, do not expose to temperature extremes and prevent contamination from foreign materials.


Our laboratory tests have shown Aberdeen Foam 6% AFFF-LF concentrate is compatible in all proportions with other high quality low freeze aqueous film-forming foams and ABC and BC firefighting powders.

However, in order to maintain EPA 2010/15 compliancy, it is recommended that C6 foams are not mixed with any other foams.

As recommended by NFPA 11: 2021, we would advise that if mixing foam concentrates from different manufacturers a compatibility study is carried out beforehand. Different types of foam concentrates - for example AFFF and Protein Foams - should never be mixed.

For further information or advice on compatibility testing, please visit our Knowledge Base or contact us.


Produced Aberdeen Foam 6% AFFF-LF can be safely disposed of in biological waste water treatment systems.

Inspection & testing

As recommended by international foam standards NFPA 11: 2021 and BS:EN 13565-2: 2018, Aberdeen Foam concentrates should be inspected and tested at least annually as part of your fire fighting foam maintenance programme.
