Specification

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 .
* 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.

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.
