Re: The space talk is interesting, but...
I used to work for an electric utility in <mumble> which had the following major hazards:
12, 24, 69, and 138 thousand volt high tension lines
Multiple very large steam turbogenerators, all of them built by British manufacturers which meant that most of them were no longer supported as the vendors no longer existed
Crocodiles. Yes, seriously, crocodiles. Two major power stations were built in swamps because the land was cheap. The crocs liked the outflow from the cooling towers for the steam turbogenerators and were under the impression that they owned the place.
Multiple gas turbine generators, used to get emergency power if a steam unit had an oopsie.
Several hydro units.
In 30 years there were four major accidents, one fatal. Someone did something silly with a 69 kilovolt line and burned his arms off but survived, someone annoyed one of the crocs and had parts of a leg removed, someone got in the way of a GT exhaust and had major burns plus broken bones when he got thrown 20 metres by the blast, and someone else did something else silly with a 24 kilovolt line and got very dead. There were a few near accidents with live steam from the steam units, particularly from the older steam units which were running only because the company workshop built parts for them, but no-one got seriously hurt. And one bright lad managed to nearly drown himself at a hydro station.
What in Christ’s name is happing at Amazon that they have multiple serious accidents in a year?
Of course I’m only counting company employees, not including people like the bright lad who attempted to put up a tv antenna right under a 69 kilovolt line. The burn mark left by vaporized copper was still visible on the building 20 years later, despite at least two repainting jobs. Or the gentlemen who threw some wires over a 24 kilovolt line to get power to play their radio while they fixed a truck. It turns out that steel burns nicely when hit by 24,000 volts at 50 amps.
