Is 'indirect' contact with lead solder safe?

<< < (3/6) > >>

Vtile:
Yes. People are jumping on the wall with the lead these days. Mind you the gasoline were leaded in the days even then most people weren't zombies in their 20s.

As AvE always says, filter the smoke through a cigarette. And wash your hands

Then, something is placed on the floor, say, a book, which touches the solder left on the floor/comes into contact with it.
Then, someone else grabs the book, which has touched the lying around solder, and reads it, coming into contact with the 'solder/lead-contaminated' book.
Now, when touching food without washing hands, is the second person at risk of getting lead into his mouth?

This is similar to coughing on your hand when sick, touching a door handle with said hand, someone else touching the same handle, eating without washing their hands and getting the bacteria of the sick one into their mouth.

You definitely don't want to watch this then!

Lead pipes are safe enough as long as you have hard water and don't drink or cook with water from the hot tap.   The video doesn't mention iron pipes which are by far the commonest for the incoming supply in old properties.   Running a litre of water will flush out 8m of 1/2" pipe, so its a good idea to run a couple of litres from the kitchen tap before use if it hasn't been run that day, even for plastic pipes.  Don't drink from taps that don't have a direct mains water supply - cold header tanks are a breeding environment for all sorts of nasties and if poorly maintained tend to have dead rats and/or pigeons in the bottom!

I've been using lead solder for almost 60 years, and not been super-careful with it.  As far as i know, I have no effects from that.

Yeah, I've been using lead solder for a few decades and it hasn't affected me at all! (cough)
But I always wash my hands after working at the bench.  I do the cooking in our house so its pretty mandatory.  But to say eating it has no immediate affect is a stretch.  When Canada was young and the old Hudson Bay company was in the trapping business, they operated out of "camps" where their furs were warehoused and traded.  If some kids got rambunctious the camp doctor would give their parents a lump of lead for the kids to chew on!  It seemed to settle them right down! :o
