That depends. With the recently dead it would be as safe as touching a living body. If the body is obviously decomposing I would not recommend it (Who would?). At say, an open casket funeral, there shouldn't be a problem as it is usually predicted that somebody might want to touch it so is made safe.
As long as you have a healthy immune system you should be fine (You might want to wash your hands, especially before eating (but I'm sure you do that anyway))
Yes
Do not touch it with your hands, leave it alone if you think it will be safe.
Mainly our hands, but potentially any part of the body. We can also use tools when it is not safe to touch things directly.
I always leave it uncovered and it taste fine.
Yes, but be very gentle, don't take them out of water, don't squash any, and wash your hands afterwards
Perfectly safe.
I think it is safe
Yes, it safe to touch a extension cord while its plugged in.
Never assume that any electric wire, no matter what color it has, is safe to touch.
Safe to touch, but not the vapors the vapors are slightly toxic

An uncovered will will eventually become polluted with dead animals and insects that fall into it. It is also dangerous to humans and domestic animals. Cover it.
