We live with three families in a fairly large house with a connected to the primary care of my mother. This oscillates between love of the practice in the basement for the food and live here since we came already two times before that the good woman forgot the time and the content was already charred and the house itself gradually filled with smoke. Because the practice is spatially separated from the rest of the house, the smoke has broken through the hallways in the upper apartments, so was aware of me after a while, what is wrong in the kitchen in the basement. Until this hintunter in the kitchen there are when one moves rapidly almost a minute. At that time I had to go down there without the hood and you could directly in the kitchen already hardly see anything because of the smoke. In addition, they had while on the way down was a good deal of air consumed.
I had previously thought possible ever to come there in a one-room Arpartment never in such a situation and yet it happened. That shows me once again that it makes sense to be prepared. In the basement where was already self down everything full of smoke, had a simple little open the cellar window barely enough to provide enough air to grab in order to further explore the cause of the problem.
So I think, the mask can be helpful if you know your way around, or the layout of the building has just in the head. Thus, one could, because smoke is not always the same "fire" means to explore a possible cause and counteract possibly before it comes to fire damage, or may result.

The handling is easy to handle for the manual. It is advisable to do so after receipt equal to the case in order to be familiar Kries. The Soft Pack is relatively easy to attach to the eyelet at an easily accessible location on the wall to be able to access them quickly in an emergency. In addition, I think you should make use of it, because in an emergency should not be sought for a long time after the masks.
Even if there will never exist a complete security for all and that, one can increase his chances of survival no matter whichever one makes in-house. Especially with "something" larger buildings one can only guess this hood, as you quickly underestimated, which a fast air can go out next to the pick-up his neighbor and the way out.
