OK, I’ll admit it. I actually added a flashing red light outside my shielded chamber door to indicate high-power RF within the chamber. I controlled it by simply plugging in an extension cord to the switched outlet on the rear of my big RF power amplifier. There had been no requests from safety or insurance people; no, I did this all on my own.
See, the RF chamber looked so high-tech cool, with all the blue pyramidal absorbers and shiny copper tabletop, that management had my lab as a regular stop on the “Executive Tour Route.” This was one of those pony shows where, when the execs wanted to impress somebody about how high-tech we were, they would take them on a walking tour of selected engineering areas. Honest to God, once I put that red strobe light in there, I found my petite cash vouchers got processed faster and my annual budget seemed to get less trimming. A totally excellent return on investment!

Human Exposure Limit will not apply if no human is in RF chamber when RF is on.
