Anything else that could go wrong that I
should be concerned about?
Use some kind of glasses when working with any kind of engineering,
protective glasses or magnifying glasses, for example.
Cheap reading glasses, strength +0.5 or +1.0, are very useful when
working with electronics.
When working with high or unknown voltages, keep one hand in your pocket
and wear insulating shoes.
Electricity can only hurt you seriously if current finds a path through
you body. If you only use one hand you do not give the current a chance
to go through your body. Don't lean with your other hand against the
kitchen sink while measuring mains voltages
Remember that current makes the muscles cramp, so you cannot simply let
go of a tool or a wire.
My father who was an electrician told me about when he was caught in a
serious situation once. He had climbed 7 meters high on a pole and was
trying to cut an insulated wire. The wire should have been disconnected
but it wasn't, so when he got through the insulation he got current
through his body because his climbing gear touched some grounding wire.
He could not let go of the wire cutter because his muscles cramped, and
he felt his mind was going black. He knew that the only way out was
to cut through the wire completely.
He slowly woke up again, found himself hugging the pole with both arms to
avoid falling backwards, breaking both his legs and falling. He had
managed to cut through the wire before passing out completely.
As long as you use only low voltages, under 50 Volt, you don't have to
worry about such problems, but it doesn't hurt to be aware of them.
