Who cares if it is lead? It’s probably the least contaminated thing in the rubble. Cut it down and test later to decide where it could be properly disposed.
Now, about properly disposing of everything from nuclear waste to baby diapers. Geez, everything eventually leaches into the soil and then the rains come washing it downstream to, well, everywhere.

I believe they have to cut the scaffolding, most likely with a torch, which could potentially expose workers to lead fumes. Personally, I think the hazard is overrated. Put them in respirators and move on.
