the need to refrain from certain behavior ( prohibition sign ) in order to avoid accidents, such as smoking or handling other open flames due to the actual presence of explosive gases, dusts and vapors, e.g. B. near petrol pumps ,

the need to show certain behavior ( mandatory signs ) in order to avoid accidents or to mitigate their consequences, e.g. B. the requirement to wear safety helmets in certain areas , or to avoid damage to health , z. B. the requirement to wear hearing protection or a respirator in a certain area,

on the other hand, they should point to

Paths to rescue ( emergency signs ) and escape from danger areas, e.g. B. on escape routes , rescue routes and emergency exits in the event of fire ( fire protection signs ) , or protected areas, e.g. B. Shelters in tunnels or in the event of a tornado etc.
