Re: VAX field service engineers
A friend of mine reached behind a large bank of relay racks and managed to get his Rolex watchband across the large 48V supply ... The resulting loud "CRACK!" and fans spinning down, coupled with the smell of roasting/burning pork, were rather disturbing. To say nothing of the screaming. I managed to calm him down & get him to the ER ... Xrays showed little balls of gold melted into his wrist behind the 3rd degree charring. The surgeons later told him he was lucky to still have full use of his hand. Today, 40 years later, the scarring is still impressive, despite skin grafts. He got a new band for the watch, and now wears it on his other wrist. It still works.
And people wonder why I always take off my wedding ring when working on electrical stuff. Yes, that includes cars, trucks, bikes, boats, etc.
For the record, the power supply was no worse for the wear, and the equipment in the relay rack automatically powered back up as if nothing had happened ... Thank you, Lorain.
Oddly enough, we were both working for DEC at the time. Beers all 'round for the memories :-)
Note that the "watch pocket" in a pair of Levis 501s is the perfect place to park a ring for the duration ...
