It's as important a part of your size up as the building construction, fire load and burn time.

What are your thoughts on verbalizing the venting on the radio size-up? i.e. "E-1 is on scene, 2-story residential structure with fire venting to the 2nd floor interior on the B division."

Charlie Delta side, second floor is fully involved. The windows have failed and fire is being pushed into the structure. Protection line to the stairwell, primary search of the second floor if the door to the room is still intact. If the fire is into the second floor living space, search the floors below the fire and get out.

If I had good info that no one was inside, I wouldn't even consider sending crews inside.
I'd get big water ready on the Charlie side, get a knock and consider going in after that.

If the fire was on a lower floor (living space above the fire floor) I'd REALLY have to think about sending crews above the fire unless I got a knockdown from the outside.

This is a good question and one that we should consider because wind driven fire will cause extreme fire behavior inside the structure and we have had LODDs from these conditions..

I would encourage everyone to order a copy of the NIST/BFRL study on wind driven fires that were conducted in Chicago and on Governor's Island in New York City.
