I once saw a bus-sized "RV," that was towing a car. The car was carrying a bicycle. Strapped to the bike was a skateboard. This guy was NOT going to be stranded! Redundancy - I love it!
So... what happened to the 'fire wall' separating different units? Why were the fire mains inadequate?
I don't think this fire could have been so damaging, had it not been for the 'ball being dropped' by many different parties.
I note some discrepancies in the reporting. This is to be expected: the local reporter can't be expected to know much about anything - and the usually don't
Did the guy bypass the receptacle? Or the breaker? A minor point, I suppose ... I just want to know how much of a fool we have here.
I would be interested to learn if the fault that started this fire was in the air conditioner (so maybe the LCDI was doing it's job?) or in the building wiring (from the breaker being bypassed).
There are various legal principles, some defined by statute, some by tradition, that could be used to address this DIY disaster. If nothing else, 'reckless endangerment' and 'criminal damage to property' come to mind. Remember ... even if the person was allowed to deliberately start a fire, they are responsible for keeping it under control.
How hard the local authorities want to work is another matter.
I'm glad no one was injured. By all appearances, it looks as if the place was a fire trap that needed to be torn down.
