Escape Routes

see also Evacuation (Safeguarding); Depending on the number of persons who would have to use these escape routes in case of danger, they must have a clear width of at least one metre. It must be prevented that hazardous substances or gases be stored or can be released on escape routes. Walls, ceilings and floors of escape routes have to be made of materials with at least low combustibility and low smoke propagation.
Escape routes may not be cluttered, constricted or blocked (i.e. by objects that easily fall over) and, like emergency exits, must always be ready for use and be recognizable as such without any ambiguity.
