DIN EN 12453 requires that power-operated doors should be provided with safeguards against the hazards of crushing, shearing and pull-in points, unless the doors are used with dead-man control. Hazard points up to a height of 2.50m should be considered, and also situations in which a person can be lifted up by the door. DIN EN 12453 requires a switching protective device which ensures that the door immediately stops even before the hazard point is reached.

Roller grille doors
Since roller grille doors can lift up persons, hazard points 1 and 2 must be protected in all cases. Pull-in protection at hazard point 3 is necessary if the distance between the upper face of the finished floor and the lower face of the ceiling is less than 2.50m and the wrap-around roller is not suitably enclosed.

Roller shutter doors
Protection at hazard point 1 is necessary if it is considered conceivable that persons could be lifted up by the shutter elements, or the height of the hazard point is less than 2.50m. Protection at hazard point 2 is necessary if the distance between the upper face of the finished floor and the lower face of the wrap-around roller or its enclosure is less than 2.50m, or the roller shutter armouring is such that persons could be lifted up. Protection at hazard point 3 should be provided as described above for roller grille doors.

Sectional doors
Protection at hazard point 1 is necessary if it is considered conceivable that persons could be lifted up by the moving door segment, or the height of the hazard point is less than 2.50m. If a hazard point exists also on the inside of the door this must be protected if it is lower than 2.50m or if persons could be lifted up.

The mentioned cases are recommendations only. For further information please ask the TÜV or other competent authority.
