Is this true? I wouldn't have thought that safety would be required there, is the same true for something like a substation plant? Those have warning signs all over.
Part of it is worker safety too... But in general if someone chooses a substantially less safe design and then a thief breaks in and gets injured, yes they would probably end up paying out.
In the USA, that's normally what "up to code" means. Exceptions from code requirements are quite easy to get, but if you have an exception and someone gets injured, all the liability will be on you.
