Since we are talking about H&S here, I will throw this in as it's a recent
incident that happened (although doesn't really apply to computers):
Someone was working on hydraulic equipment to replace a leak. He placed his
finger over the hole where the leak was (so as not to lose it's location)
and the equipment was turned off, to prevent pressure building up. However,
pressure built up and well... the result was hydraulic fluid being forced
through his skin into his blood. He was quickly attended to by medical staff
that cut open his hand and carefully removed all traces of the fluid. There
is a horrific picture too, but it's not a pretty sight.
I know the same sort of thing can happen with high pressure air tools if you
are foolish enough to place your hand (or any other part of your body)
against it and release the air. However, in that case death (heart attack)
would be almost instant.

I think it depends on the tool. I am not sure if you'd class a logicdart
as a tool, but I would certianly try to catch that if it fell. It is not
going to do me much herm (it's not sharp or hot), and it would be
impossible for me to replace it (hard to find, and I couldn't afford
one).

Another good practice is to step back immediately
when you lose your
grip on a sharp or heavy tool. Burned or bleeding feet and missing
toes aren't much fun.
This reminds me of 2 other things I was taught, when removing a pulley or
similar from a shaft. If using a puller tool, don't stand in line with
it. If it releases suddenly, it will fly off and hit you. For large
pullers and parts, broekn ribs, etc are a distinct possibility.
If yuo are supporting the pulley on a bench vice and either tapping the
spindle out or suing a puller, put the nut back on by 2 or 3 turns.
Firstly to protect the threads on the end of the spindle, and secondly to
protect your feet brom being hit by the falling spindle when it does come
off.
