The cleaner cut the power at the circuit breaker. It isn’t like they had an extension cable running through the middle of the room that they tripped over. In what world is that equivalent to “making customers with children traverse the artisanal glasscraft section to get to the toy section”? The RPI campus does have UPS and emergency generators because it is important, so the whole lab is protected from power failures. They put a sign on the fridge for the short period of time that the alarm was going off while waiting for repair just in case someone wanted to do something crazy, like pull the fridge out and unplug it. You can’t account for every single thing someone might do. What if instead of going to the circuit breaker to cut the power, he opened the fridge and pulled all the samples out so he could clean inside? Or did just unplug it? or something else stupid? I’m pretty sure there are a lot of businesses that would lose a lot of money if staff members started flipping off random circuit breakers to various systems and pieces of equipment.

> You can’t account for every single thing someone might do. yes you can. It's called security, and it has been a booming industry since at least 4 decades. People will do stupid things because they think differently, have different things in mind,... Never wonder "if" they will do it, but "when" > if staff members started flipping off random circuit breakers If they are accessible to them then they shouldn't cause damage. Just lock the cabinet if nobody should touch them. A lock is 30$, isn't it? A tag with a phone number for maintainance is 5$ ? > They put a sign on the fridge So they knew they were 1 switch away from disaster, human intervention or not. I hope it had proper SIL rating, if they are mad now it failed. Either humans are nice and well intentioned but stupid, and it's a shame to blame them when they just tried. Or they're really evil, and then you need to protect the system from them. Anyways, it's stupid to blame workers afterwards. UPS should have been directly between the fridge and the wall, without switch in the middle. And it should have warned staff. If not, they had accepted the risk. The fridge was also already malfunctioning and required maintainance (hence the temperature alarm) So I'm surprise there was no monitoring whatsoever, just a sign, and now they are mad about its failure. It's not consistent.
