I read an interview with an expert of restoration of historical sites. The guy said these things are super flammable and it's very likely for fires to start and smolder somewhere out of site for hours during restoration projects. Ie, drippings from welding, power tool heat being conducted through old piping, open flames, etc and so on. Fire prevention protocols are supposed to be strict including a constant fire-watch so that fire break-outs can be responded to immediately.
So I bet money the cause are lazy / incompetent brown construction workers not following regulations.
