Nice video, Arson. A tip that I would add is to use small gauge electrical cord for the wraps. This can be an old extension cord or cord from a discarded small appliance, etc. The reason I recommend this is to prevent corrosion on the tool. I used to use small cord as madcrisis suggests, but have found that this retains moisture against the tool handle for an extended period of time after getting wet. When it came time to redo the grip on the tools, I had to spend a lot of extra time removing and retreating for rust before the new tape went on. Electrical cord does not retain the water against the tool handle nearly as bad. I attached a pic of my personal tools. I do the pink addition each October in memory of the wife of one of our members (who is also a lifelong friend).
As to the overhaul after a fire, no, the homeowner would not be better off if we left the slab. The insurance company seldom pays enough to cover everything. Also, in my response area, the vast majority of occupants have no insurance, whether they are owners or renters. And the insurance proceeds cannot replace photos, grandma's china, etc. We aggressively attack the fire, ventilate (remove smoke), and do salvage work (cover furniture and belongings) to minimize damage and loss as best we can. Overhaul is completed to ensure the fire is out. If we miss a little smoldering wood of a door frame because we did not pull the trim off to make sure, and then return a couple hours later to fight a working fire again, then we failed in our mission. But don't get me wrong, we don't tear stuff up indiscriminately. We open up where we see evidence of or suspect that there may be hidden fire or smoldering material. As Arson said, once we find "clean" wood, we can stop in that area.
Thanks, again, Arson and all you other jakes. Stay safe.
