If you are not disturbing the questionable lead paint, by sanding or some other disturbing method, why would you be breathing it in. When a board is pried off the building there is no lead paint dust to inhale, maybe large chips which could be spit back out.

Sounds like a conundrum. To reuse the barn or not to reuse the barn. TB, if you don't salvage these structures what is going to happen to them? Would they be bashed down then hauled to a land fill or burned in place? Just a couple of possibilities that would still fall under Jim's quandaries. Neither would satisfy the problem.

Jim, do you have any real life timber frame salvage examples of these issues being dealt with in the past? Or is the lead issue coming from home restoration world where a crew is salvaging and reusing crown molding and fancy trim work inside and outside of a house? Lots of dust involved there. How real is the concern?
