Basic Electronic Safety Answered

Hello all! I'm beginning down the route of hobbyist electronics. As to basic safety precautions I'm really quite unsure. I know inside many electronics parts and devices (For example, a TV one would strip for parts,) there are many nasty chemicals. I don't want to get lead poisoning or any other sickness. If you could point out some safety precautions, I would be incredibly grateful (Ex. Always wear gloves, wear a mask when soldering, when stripping a TV...., etc.).

Thanks for your time and help!

wash your hands after you finish.
don't touch capacitors or anything connected to them until you know how to identify dangerous ones (Eg, power supplies! esp. in a TV). Physically bigger ones are usually more powerful, and therefore dangerous.
Capacitors (And therefore electronics) can store charge for a long time after it was last plugged in. Don't assume it is safe to touch
Solder in a well ventelated area. Outside? fume hood? fan blowing through a charcoal filter (there are instructables on here about that. not sure if it actually cleans..)
solder irons are hot. Make sure you have a good stand for it, if it falls off the table when you pull on the cord, you are looking for burns.
stick with low voltage stuff (5V DC) until you get the hang of it, much harder to hurt yourself there, even when it goes wrong.
Watch out for sharp edges. the internals of a tv or somesuch generally arn't meant to be poked around in, so all the metal edges can be sharp. Same goes for plastic you break to get into devices.

Old electronics are a good source, the older they are the less system-on-a-chip stuff you can't reuse.

don't breathe the dust from cutting circuit boards.
