All this at the very low cost of: your job. You can't have an unbreachable blockade 24/7 in front of there, very soon they'd send police to disperse. Fire dept has to justify the failing, if everything up to code and the inspector make it fail it will delay for at most a week and the guy will lose his credibility. The guys delivering and installing the UPS are just trying to make a living too, destroying the thing will get them fired while only delaying a little the time getting another delivered. You are replaceable.
