Applications
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.
Compatibility
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.
Disposal
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.
