Labs I've built in the past have an interlock on the door(s) to shut down RF to the antennas and/or amplifiers when the doors are unlatched. Lights at the control point show the status (red - open, green - closed). The turntables were interlocked to the hatch for access to the turntable pit. With the hatch open, no turntable rotation.

Pettit From: Charlie Blackham [mailto:[email protected]] Sent: Thursday, January 09, 2014 12:39 PM To: [email protected] Subject: [PSES] Risk Assessments and mitigation for EMC chambers All Client has performed risk assessment for turntables and high RF fields in their anechoic chambers and is looking at implementing emergency stops for the former and flashing lights warning of the later. (I've never seen flashing lights at other labs whilst witnessing tests up to 350 V/m, and the client chamber will only be used with amps < 250 W). The turntable is not flush to the floor, so does present more hazard than some, and some operation does require people to be on or adjacent to the turntable for operation/maintenance. There is already plenty of good "process" and supporting documentation and everyone with access to the chambers have already been through a thorough safety briefing. Anyone have any documents or stories to share as to how they have satisfied/pacified/dismissed enthusiastic Health & Safety officers who still want to "do something"?
