AHJs tend to try to worry property and firefighter protection into 13D. Reasonable from their point of view, but the idea behind the standard is 1. get everyone out and 2. make it cheap enough to b attractive to all the naysayers. If the occupants escape and it burns to the ground no problem, met the performance spec (everybody got out). If it's too dangerous for firefighters to enter and people are inside then it failed. If it's dangerous and everyone is out leave it be. Don't get on the roof. Don't ventilate. Don't attempt a save. Surround and drown is the proper response. adding sprinklers too unoccupied spaces like garages won't help with 1 and will be detrimental to 2.
