Where firefighters come to talk training

When do you ventilate?  After fire to remove smoke and heat or before access to prevent smoke and heat from entering stairwell and hallway?  Discuss.

Scott this is a pretty broad question in regards to high-rises as the answer to ventilation of high-rises is driven by the building and it's systems. The second part to answer this is the occupancy of the high-rise itself.

Yes, I guess it was too broad.  I more or less wanted to see if a discussion would follow and wanted to see what factors would come into play (ie. Wind drive fires, vented stairwell, pressurized stairwell, Measures M, height, new construction, etc).  I will just throw it out there...I have been assigned the upgrade on our P&P and was looking or new methods that may have been incorporated into SOG's or SOP's.  Any comments appreciated.

Over the years are department would vent while suppression was taking place. Like most departments, manpower during the day was playing a roll. We now pressurize the home while doing suppression. I wasn’t sure how this was going to work, but after several fires, I like it! I think venting has it’s time and place, but you need to have the key players in place when it’s performed.
