Description Chemguard 3% 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 3% ( 3 parts AFFF concentrate to 97 parts water) on Class B hydrocarbon type fuels such as gasoline, kerosene, diesel, etc. Chemguard 3% 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. Canada Listed U.L. recommended application rate on hydrocarbon type fuels is .10/ gpm ft² . FM Approved Performance to ICAO, Doc. # 9137, Part 1, Chapter 8, Level “ B” verified Suitable for use with fresh or salt water Excellent wetting characteristics when used in combating Class “ A” fuel fires Suitable for use with both 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 3% AFFF is not compatible with galvanized pipe or fittings in an undiluted form. Suitable for use with siliconized dry chemical extinguishing agents PROPORTIONING Fixed or portable in-line eductors In-line balanced pressure and pump pressure proportioning skid Bladder tank balanced pressure proportioning systems 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 FOAMING PROPERTIES Aspirating type discharge devices typically generate expansion ratios between 6-10 to 1 when 3% 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 devices, flow rate and discharge pressure. TYPICAL PROPERTIES AT 77º F ( 25º C) Appearance Clear Slightly Yellow Specific Gravity 1.02 pH 7.7 Viscosity 1.5 cps ENVIRONMENTAL IMPACT Chemguard 3% AFFF is biodegradable, low in toxicity and can be treated in sewage treatment plants. Please refer to Chemguard Technical Bulletin regarding foam products and the environment. STORAGE If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35º F - 120º F ( 2º C - 49º C) a shelf life of between 20-25 years can be expected.
