Escape hood
An escape hood (also: fire escape hood ) is a protective hood made of coated fabric with an integrated viewing window and multi-area filter, which is mainly used by the fire service to rescue people from smoky areas, mostly from burning buildings.
This hood usually consists of plastic-coated textiles, a relatively flexible viewing window made of plastic and a filter integrated into the escape hood . The filter prevents the penetration of toxic by-products ( gases , vapors , soot ) and carbon monoxide , which are present in the smoke of a fire and can lead to fatal smoke poisoning. The protective effect against carbon monoxide (CO) is achieved by a catalytic filter ( hopcalite ), which catalyzes the oxidation of CO with atmospheric oxygen to form CO 2 .
In principle, an escape hood is a self-contained breathing apparatus (escape filter device) that filters out toxic gases from the air. In contrast to compressed air-operated breathing apparatus , an escape hood does not protect against a lack of oxygen in the surrounding air .
Newer design escape hoods are mainly used by fire departments. They also have a viewing window and are largely made of flame-retardant plastic. A compressed air breathing apparatus can be connected to it. The overpressure generated in the escape hood also means that it does not have to be completely sealed, and toxic gases cannot get inside. In addition, the person to be rescued is supplied with fresh air. For the wearer of breathing apparatus to whose compressed air breathing apparatus the escape hood is connected, this means an increased consumption of breathing air, since the person to be rescued is now also supplied with breathing air.
