Gotta love this. This is an Associated Press video from Portland (OR.) Check out how quick conditions improve, when it’s coming out like that it’s no longer beating up the crews inside. Unfortunately the video starts a little later than we would have liked to have shown, but you get the point. It appears that they are just finishing punching through the ceiling below as the video starts. While we understand that many departments do not support vertical ventilation, it’s hard not to agree with its effectiveness (that is not an invitation to argue it here either.) Some people get startled when it lights off like that, remember, that’s what’s supposed to happen. This allows the crews inside to press-on to the seat of the fire and take care of business. A vent like this DRAMATICALLY IMPROVES the conditions on the inside. Get the vent and get off the roof, job well done.
