Re: Spanner in the works
I have that training every few years. Luckily I don't actually have to ever work on anything over 240 V. We had some sparkies here who made themselves a lovely secret break room with chairs and a table inside an equipment room, behind a steel door with a big "Arc Flash Warning! Authorized Personnel Only" sign on it. Yes, the entire inside of the room was technically in the zone where a protective suit is required.
They're no longer employed here.
