Stand on a rubber mat and keep one hand in your pocket. Know where the
other hand is at all times.
Avoid live testing if possible, clip the leads on before powering. Use a
shorting stick. Tag switches if high power.
Work with someone you trust. Common sense.

You imagine that you are protecting yourself, but your
protection efforts remind me of the comic routines where
some hapless character gets dressed in a hazardous waste
suit, complete with a hockey mask, ski goggles, tongs, and
oven mitts all to take a soiled diaper out to the trash.

A linesman's glove so completely eliminates any dexterity,
that safe manipulation of something as tiny as an anode
lead is awkward at best... all to protect you from a zap
that is no more potent than a static zap to a doorknob in
the winter.

Latex surgeon's gloves during electronic work, is a fool's
folly beyond belief. The glove, by virtue of its sealed
nature will capture your hands sweat, covering them with
a highly conductive layer that is capable of reducing your
skin's protective resistance to a point where even 24V could
conduct enough current into your heart to be fatal.

Further, DC rarely if ever can cause a heart to enter a fatal
rhythm. It will, at most, skip a beat, and continue on in
its normal rhythm.

Stop trying to improvise safety, you lack the experience to
be able to recognize safe and unsafe methods. Instead, please
study some legitimate sources, and learn about HV safety, as
it pertains to TV and radio repair. If you can't, please,
please do your friends and family a favor, and take up stamp
collecting, or golf.

Chuck,

The only use of the linesman glove was to put the HT anode lead
somewhere that would hold it from moving, and to keep it away from me. I
never implied to wear them while working in electronics, they also have a
leather shell glove to protect the linesman glove from damage.

But I do use latex gloves when doing this work, I'm not relying on them
to protect me, but rather to add a weak safety net, since I have them lying
around, they improve grip, and add a decent layer of uncertified
protection, but they tear easily.

This reply is a little dated I know, haven't been following the thread
for awhile.
