I read the following statement in a SOP in regard to PPV & exposure control.
Once smoke has cleared, the exit should be closed, the building
sealed, so that it will "over pressurize" the exposure. Over pressurized air will force hot gases back across the beaches, or back
down common attic spaces towards the fire area. This can prevent fire spread extension.
The second most critical exposure would then receive PPV in a similar manner.
The next priority would be the fire occupancy.
Does anyone have any experience doing this? Does it work?
