Aberdeen Foam 1% Class A
0.1-1% Class A Foam Concentrate
A synthetic Fluorine Free Fire Fighting Foam concentrate for Class A fires, e.g. forest fires, structural fires and tyre fires.
Designed to offer superior penetration into burning Class A materials. Formulated for use with either fresh or seawater.
Highly versatile and suitable for use with a range of equipment, methods of application and proportion rates - intended for use between 0.1% and 1.0%.
Can be used on small Class B hydrocarbon fires such as fuel tanks leaks or minor spills.
Not suitable for use on fuels which are polar solvents and water miscible such as alcohols, ketones, aldehydes and ethers.
- Provides quality protection from Class A fire risks such as rubber tyres, coal, paper & wood and forest fires
- Economical - proportioning rates of between 0.1% and 1.0%
- Versatile - can be used in different equipment and application methods
- Easily premixed and excellent foaming properties
- Free from elements harmful to soil - no negative effect on reforestation
- Suitable for use with Compressed Air Foam Systems (CAFS)

Applications
Aberdeen Foam 1% Class A concentrate provides quality protection wherever Class A materials (ie. tyres, paper, wood) present a fire risk.
Suitable of use at Class B minor incidents such as small hydrocarbon liquid spill fires.
Proportioning Information
Use between the following proportions:
- Helicopter buckets: 0.3 - 0.6% (between 3-6 parts foam concentrate to 997-994 parts water)
- Handline air-aspirating nozzles: 0.3 - 0.5% (between 3-5 parts foam concentrate to 997-995 parts water)
- Handline non-air-aspirating nozzles: 0.3 - 0.6% (between 3-6 parts foam concentrate to 997-994 parts water)
- Compressed Air Foam Systems (CAFS): 0.1 - 0.3% (between 1-3 parts foam concentrate to 999-997 parts water)
- Use in fire breaks or small hydrocarbon fires: 1.0% (1 part foam concentrate to 99 parts water)
Proportioning rates will vary depending on the quality of the foam blanket required and are given for guidance only.
Aberdeen Foam 1% Class A foam concentrate is readily proportioned with the following equipment:
- In-line inductors (fixed or portable)
- Balanced pressure variable flow proportioners
- Around the pump proportioners
- Bladder tank Balanced Pressure proportioning skid
- Handline, aspirating nozzles with fixed inductor pickup tube
