Aberdeen Foam Vapour Shield (Acid) C6

6% Acid Vapour Suppressing Aqueous Foam Concentrate

A high quality vapour suppressing foam concentrate which is compliant with the EPA 2010/15 PFOA Stewardship Programme.

Designed to provide an effective and stable vapour suppressing foam blanket on acid spills when used at 6% concentration.

Can also be used at 3% concentration to quickly extinguish and secure fires involving both:

  • Class B hydrocarbon fuels such as crude oil, gasoline, aviation kerosene and fuel oil
  • Polar solvents and water miscible liquids such as alcohols, ketones, aldehydes and ethers.

Formulated for use with either fresh or seawater, Aberdeen Foam Vapour Shield (Acid) C6 triple capabilities reduces the need to stock different foam types.

How do Vapour Suppression Foams work?

Many chemicals can destroy foam by combining with the surfactants used in its formulation, changing its pH or removing water by reaction or dissolution. Vapour Shield (Acid) C6 has been specially formulated to work effectively with acids without any adverse reaction.

When used at a concentration of 6%, Vapour Shield (Acid) C6 provides a stable, slow draining foam to effectively suppress vapours from accidental acid chemical spills.

Environmental impact

  • Contain no fluorosurfactants of chain length greater than C6
  • Biodegradable      
  • Butyl carbitol free
  • Low fluorine content
  • Low toxicity to aquatic organisms

Applications

Aberdeen Foam Vapour Shield (Acid) C6 concentrate provides quality protection wherever acid spills are a risk:

  • Road tankers and rail cars
  • Chemical storage facilities
  • Industrial processing areas

Also suitable for use as a fire fighting foam on Class B Hydrocarbon and Polar Solvent fuel fires or as a wetting agent for combating Class A fires (i.e.tyres, paper, wood).

Proportioning Information

Vapour suppression:

  • 6 parts foam concentrate to 94 parts water (using a medium expansion nozzle)

Hydrocarbon fires:

  • 3 parts foam concentrate to 97 parts water

Polar solvent fires:

  • 3 parts foam concentrate to 97 parts water

Aberdeen Foam Vapour Shield (Acid) C6 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
