The Dräger PARAT 5520 Soft Pack fire escape hood provides protection against gases, vapors and particles. Creating the fire escape hood is quick and simple, so it should also create a layman under pressure in an emergency situation and also still offers the company Dräger this a video. The hood is designed to protect a 15 minutes before smoke and fumes. After use, you must always replace the filter, this can buy more. Is without being in use, the cap protecting a total 16 years in which you should change the filter after 8 years without use. I find the Dräger PARAT 5520 Soft Pack Fire Escape Hood very reassuring, especially if you live on the upper floor of a multifamily house. In case of fire you have a good chance to escape, even if the smoke has arrived already in the stairwell.
