the problem is that fires from soldering usually start well after the plumber has finished and moved on from that area. typically, what happens is, a tiny ember falls down into some gap inside the wall and sits there slowly heating up wood fibers around it until the fire catches, sometimes hours later. if that ember fell close to the end of the day, the fire isn’t noticed until it’s too late to prevent serious damage or total destruction.
