FIRE SALE!

I agree. Most devices are expected to be heated briefly to soldering temperatures, not heat soaked at that. Temperature in this case is much different than heat. The designers of the devices must take into account what temperature is require to do the solder assembly function, and minimize the amount of heat the device is exposed to. On wave soldering machines the heat was quite low, and these would have been assembled then. Even with current radiant oven techniques, the parts would fall off if there was an extended heat exposure. They do that often enough now with heating problems with devices, with open circuit failures happening. If you're lucky and have a quick fire department response, the setup time on the equipment is at least 4 or 5 minutes. Unless there's physical danger and the building involved may have people trapped, they take time to assess the fire, the propagation and there's more time before they attack. I've seen a couple of events and a couple of full exercises, it doesn't happen quickly. Fire departments are sadly known for letting buildings burn into the basement if it saves life or property of other nearby structures. You'd be lucky to get this out of a burned out building in most cases. Once the fire is knocked down the heat will be present for quite some time afterwards, as they let it cool and clear flash fires, and take care of nearby property. thanks jim
