You’re not even going to pretend being honest about this uh?

> An interlock prevents people from being in a place they aren't supposed to be, it does nothing for when something goes wrong in a place you are supposed to be.

What sort of nonsense is that? The point of an interlock is to keep the place where you’re supposed to be safe for as long as you’re there. And stop you from being there if it’s unsafe.

> there's always something else that can go wrong.

Yeah sure a volcano could explode from below your desk. Whatever.

It seems you're the one not even pretending to be honest here.

Obviously we are talking here about the sort of potentially dangerous work where there are serious risks to begin with.

How would an interlock keep the place you are supposed to be safe? An interlock just stops something from running when its activated. When you shut down something to go inside for maintenance or whatever, an interlock stops someone from accidentally turning it on while you're inside. But when you're not inside and something is supposed to be running, the interlock is not going to do anything to contain a mechanical failure.

Imagine someone photographing sharks. They're in a shark cage to protect them. Compared to outside of the cage, they are relatively safe. An interlock might ensure that they are indeed inside the cage before a bucket of chum is dumped to attract sharks. But an interlock does nothing to protect them from a failure of the cage - maybe due to poor maintenance part of it rusted, or perhaps there was a defect with some of the welding to begin with - as far as anyone is aware, the photographers are in a "safe" place but really they're not.
