Two guys, standing on a table under a doorway, have been extracting a metal window frame from the top of a door frame in the office of the college. Sparks were flying right across the room. The guy wielding his welding machine had goggles, but his companion standing nearby didn't (not sure why he had to stand so close). It was rather spectacular. A bit like an indoor firework display.
I'm not sure but I guess anywhere where health and safety meant anything, everyone working in the office would have had to leave or the work done out of office hours. The poor office administrator is having to sweep up the mess.
