Old men and RV ladders

[Gardner Yeaw]

Ernie,
The ring on the finger is a well known safety risk. When I worked
for IBM in the mainfrane equipment service field, the first thing you
did was take off all jewelry. Nothing like a gold ring shorted across
a 1200 amp power supply. (yes, I did say 1200 amp. The big mainframes
ran on a 1.5 volt level to supply tens of thousands of little
transistors). The really dumb thing was you had to wear a necktie and
white shirt while working on machines with high power motors spinning
all sorts of nifty things, and often covered with printing ink.

When you get down to it, a standard automotive battery will melt
that ring and burn your finger off just as well.

Once I stuck my head too close to a circuit board and zapped my
glasses, I thought they were non-conductive.
