1% AFFF Foam Concentrate

Description

Chemguard 1% AFFF is a specially formulated, synthetic, aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket. It is intended for use at a proportioning rate of 1% (1 part AFFF concentrate to 99 parts water) on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. Chemguard 1% AFFF is not intended for use on fuels, which are polar solvent/water miscible such as alcohols, ketones, esters, etc.

FEATURES

  • U.L. Listed, Foam Liquid Concentrates
  • U.L. recommended application rate on hydrocarbon type fuels is .10/gpm ft².
  • FM Approved
  • Suitable for use with either fresh or salt water
  • Excellent wetting characteristics when used in combating Class A fuel type fires
  • Suitable for use with both air-aspirating foam and standard water fog nozzles
  • Suitable for use with deluge or closed head foam water sprinkler systems
  • If inadvertently frozen, thawing will render product completely serviceable again
  • Suitable for use with carbon steel, fiberglass, polyethylene or stainless steel. Chemguard 1% AFFF is not compatible with galvanized pipe or fittings in an undiluted form.
  • Suitable for use with dry chemical extinguishing agents.

PROPORTIONING

  • Fixed or portable in-line educators
  • In-line balanced pressure and pump pressure proportioning skid
  • Bladder tank balanced pressure proportioning system
  • Around the pump proportioners
  • Handline, air-aspirating nozzles with fixed eductor pickup tube

DISCHARGE DEVICES

  • Foam Chambers
  • Air-aspirating and non air-aspirating sprinkler heads or spray nozzles
  • Standard water fog nozzles for handlines and monitors
  • Air-aspirating foam nozzles
  • Foam makers for use with either Floating Roof storage tanks or Dike/Bund protection systems
  • High back pressure foam makers for sub-surface base injection system (hydrocarbon type fuels only)

APPLICATIONS

  • Crash Fire Rescue
  • Storage tanks(non-polar solvent type fuels only)
  • Truck/Rail loading or unloading facilities
  • Processing/Storage facilities
  • Docks/Marine tankers
  • Flammable liquid containment areas
  • Mobile equipment

FOAM PROPERTIES

Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 1% AFFF is mixed with water at the correct ratio. Non-aspirating type devices will typically generate expansion ratios of between 2-4 to 1. Expansion ratios are dictated by the type of discharge device, flow rate and discharge pressure.
