Quoting Jim Thomson <jim.thom@telus.net>:
The old fella had removed the top lid with the amp
powered on !! He was gonna poke about inside to find the problem.
If the safety device was not there,
he woulda be fried. He had removed the top lid late at night, while tired.

( 1 ) Don't work tired
( 2 ) Don't work alone
Pulling routine maintenance on TV transmitters was always done after
midnight and I gave the engineer ( s ) the afternoon off before an all
nighter or midnighter . I told them to try to get several hours of
sleep before meeting me at the transmitters. I watched them
carefully for any signs of inattention or fatigue. We engaged each
other in safety and troubleshooting procedures before each step of
transmitter repair. Just keeping a conversation going seemed to be
the best way to both teach and watch for fatigue.
We never touched the "bad stuff" without a last reconnect of the
jumper cables and a voltmeter check. We were dealing with 26KV and I
didn't want to have to make a call to their wives at 3AM.
