Assessment • Hi-Ex Foam is well-understood in DoD, having been installed in hangars for years • Mechanism (smothering) is effective against many types of fires Web12 de dez. de 2016 · The foam with expansion ratio between 1:2 and 1:20 is called low expansion foam. Foam with expansion ratio between 1:20 and 1:200 is called medium expansion foam. Foam with expansion ratio above 1:200 is called high expansion foam. Drainage time. Drainage time is the measure of how quickly a foam solution can move …
WebHI-EX foam concentrate can be used to produce foam with expansion ratios ranging typically between 200:1 and 1000:1 depending upon the type of generator and the operating pressure. For this reason, it is important, for the proper design of a high expansion system, that the concentrate be specifically tested with the intended foam generators. WebHigh Expansion Foam Hi Expansion foams are ideal to use at medium expansion at minor incidents such as small hydrocarbon liquid spill fires where close approach to the fire allows hand-held apparatus to be used.
