Grounding: A basic rule for working around electrical equipment: if you are yourself not
grounded, and if you only touch one single component at a time, risks are reduced.
Never ground yourself through your feet. Don't stand on a wet floor. If it's necessary to
touch electrical components in such a location, a trained electrical worker uses a dry
ungrounded platform such as boards or a wooden ladder.
Rings and watches: When working around electrical equipment, first remove rings and
watches to reduce the risk of electric shock. At an IBM test site in Poughkeepsie, NY in
the 1980's a test technician was killed while working on a computer. His metal watch
band contacted a live component while other body parts were touching a grounded
component, possibly the steel frame of the assembly. Similar accidents around electric
panels are a real risk for home inspectors.
Never Assume You've Turned Power Off - Use a Neon Tester, Voltage Detector, or Multimeter
NEON TESTER
The most basic electrical safety procedure I can think of when working on
electrical devices or electrical wiring involves knowing how to: turn off power to
the device or circuit or system where you're planning to work
make sure that power is really OFF.
I never touch something electrical that I've "turned off" without using at least a
neon tester to or a voltage detection pen to see that electrical power is really off.
In 1970 I turned off power to a junction box to fix a light - the light went out - so I
figured that all electrical power to the junction box was really off. Then while
wiggling wires in the junction box I got a huge spark and a little shock.
Some nitwit had run two different live circuits into the same junction box.
