2EAGOSH Recommendation May 2007

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.

4EAGOSH Recommendation May 2007

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

5EAGOSH Recommendation May 2007

Automatic stops on all doors at close position.

Low speed operation (approx. 10 mtrs per min)

All wheels and cogs fenced off.

Preventative maintenance programme to include a weeklyinspection of the safety devices on each door.

Fence off the inside of each door to prevent ride on, orother events which could lead to personnel entering into oron the doors.

6EAGOSH Recommendation May 2007

Install magnetic locks on personnel doors which are activated bythe main door movement to prevent door opening.

Change the control button operation into a Joystick type controlwhich will be easier for the operator to activate and understand.

Upon installation of the controls undertake a staff briefing on thenew method of operation

Position the tow bars at a central location.

Install new signage to outline the essential safety/operatinginstructions.
