John,
As always the Q&A is the decider. The above list is items that I have personally seen that were also deemed illegal in the past.

Adam,
Uncontrolled is exactly what I saw, no method used for shutting off the compressor. It ran until a pop-off valve operated. The original owners had bypassed the switch because of some issue. The leaking air was one of things that alerted event people of the compressor.

BTW, LRIs are not the only people that have to be satisfied at an event. We merely interpret the robot rules of Section 4. UL Safety people, event staff, venue staff and FIRST staff present at the event, all can and will step in when safety concerns are present.
