I'll see if I can find it again, it was somewhere on the web about 5 years ago.

This isn't the article that I read back then, but it covers the same ground:

The guys over at iFixit, who sell a repair kit so that you can fix your own electronic devices rather than throwing away (or sending them back to the manufacturer for repair at an astronomical price have a huge goal: To eliminate all electronics waste. Aggressive, yes, but I think these guys have got it right.

This is actually a very important argument AGAINST lead free electronics. The higher melting point of lead free solder combined with copper migration of the acual copper laminate mean that lead free products are almost unserviceable. I can pull an IC off a PCB and replace it around 10 times before the board starts to wear out, yet lead free typically fails at the first or second attempt to rework. I too don't like trashing equipment that has given a few good years of service and then dies, but that ideology is being made near impossible by European legislation that is causing a global move to lead free.

There are standard procedures to prevent exposure, as their are for other toxic substances, but you are rigth. You and your employer need to be aware of the hazard before implementing them.
