But, as long as you're only touching the plastic part, you'll be OK -
the reason for the safety warnings is becase if one hand is grounded,
or you're standing in water, and your hand slips and contacts the HV
AC, it can kill you.
The point is to not give the current any path through yourself, but
like I say, the little neon testers should be OK, if you're only
holding the plastic part.
More specifically, the "one hand in your pocket" rule is intended to
prevent the situation where the "active" hand touches live while the
"spare" hand is resting on a grounded case, resulting in a relatively
low-impedance path which goes in one arm, across your chest (through the
heart), and out the other arm.
If the spare hand is out of the way when you touch live, the current faces
a relatively higher-impedance capacitive path, and most of it avoids the
heart.
It all make sense now.Thanks to Rich and Nobody and also the rest for
all the clarifications given. Really appreciate that.
