Snap On has a safe that indicates it is water resistant and heat resistant, total defense line, I believe. I remember reading somewhere here that most damage done in a fire is water based when the firemen (firepeople?) Put the fire out. Yet, I don't see anyone ever recommending these. It seems to me this would be an important feature but it's not discussed at all. Why is that? Should this not be a check list item when purchasing? Looking right now probably purchase later this year.
