Andy, I would suggest they should have bottom edge sensor and infra red beams as a minimum to detect personnel. They can be designed to suit the type and frequency of traffic with radar detection, magnetic induction loops, radio control, wall mounted push buttons and so on. If you have a proximity sensor fitted to a door frame the door will stop its downward travel and retract when the beam is broken. There have been numerous cases of personnel being injured by roller shutter doors for whatever reason. You may also want to consider eliminating hand or foot holds on the doors to stop people being lifted by or travelling on the door. Regards, Thom

Andy, There are types of roller shutter doors also fitted with a rapid plastic shutter - so during the day only the lightweight plastic shutter needs to go up and down, and the actual metal shutter is only closed at night. My main customer has six of these rollers doors, and a lot of FLT traffic. Each entrance also has a 'wicket door' to the side for pedestrian entrance so they normally don't need to walk under the shutter - but they sometimes do if they are pulling a pump truck load, so a manual operation option is needed. Devices fitted: Person sensor at knee height Metal truck detector (in-floor magnetic device) Impact sensor They need maintenance. The motor, or if the roller gets stuck, are accessed using a mewp and WAH-trained fitters.

Thanks to all the replies it is very much appreciated.

I have no details at the moment, but I have just been made aware of a fatality involving such a door and a contractor operating a cherry picker in Belgium. If I find out anything further, I will post.
