Not incorrect. I did predicate my post with the disclaimer that I wasn't going to discuss fluid failure. By the description of the scenario, the type IV had failed, however, I wasn't there to judge it. Perhaps I shouldn't have used the word contamination, as that might have thrown you off. However, prior to failure, in a snowfall scenario, the fluid does absorb contamination. That is what it is designed to do. Prior to fluid failure, the contamination will not prevent the fluid from performing properly. That performance involves shearing off, and taking any contamination that it had absorbed with it.
