The function of the hangar doors is to open and close toallow aircraft, vehicles, equipment and personnel enter andexit
The movement of the doors can produce hazardoussituations which cannot be avoided in the design.
These hazardous situations include collisions, impact,crushing, shearing and drawingin points.
Safety devices and operational procedures can be insertedand/or implemented to reduce the risk to the lowest levelpossible.

To reduce the risks to the lowest level reasonable practicable thefollowing controls have been introduced.
Interlocks on each set of personnel doors
Two Safety Edges on the end of each door
5 Flashing beacons on each door
Warning sounders on each door which activate before door movement
Emergency stops at each control switch on each door
Emergency stop buttons at each personnel door and at end of each door
