When our insurance company inspected our chamber years ago they demanded that we install Emergency Lighting and Exit Signs inside the chamber in case the power goes out and someone was inside. We tried to explain that this could not be done and maintain proper function of the chamber. We finally talked them into a compromise. We installed Glow-in-the-dark tape on the floor near the chamber doorway and on the door handle. Actually, that was a good idea.
As far as the antenna goes, we only run 100 watts max power so we don't bother interlocking the door. Our turntable is flush with the floor so not likely to cause a hazard. For us the greatest risk of injury in our EMC Lab is as John mentioned; having a large heavy EUT fall on you, fall off the table onto your foot, or smash a finger or two. Then maybe a shock hazard from exposed voltages on EUT when troubleshooting or installing modifications. Cuts and lacerations due to sharp edges on sheet metal, pins on PC boards, and copper tape. A heart attack or stroke due to pressure is probably the most likely cause of a death in the EMC lab. Hee hee.

A safety briefing won't help if a 400 lb EUT slips off the turntable on to your foot. I think emergency stops are not only reasonable but would be required by law in some jurisdictions, and I don't see any EMC issues. Flashing lights are another matter; EMC issues exist and implementation is not as easy as for emergency stops. Can you show that the applicable human exposure limits cannot anywhere be exceeded with the max amplifier and antenna? -- OOO - Own Opinions Only. With best wishes.
