Once upon a time, there was VES. Then, thanks to the FDNY, came VEIS-vent, enter, isolate, search.

Problem is, while the concept is still sound, it’s becoming harder to isolate rooms. The so-called open floorplan is eliminating walls and doors.

It's also making searches tougher because following the walls won’t let you reach far enough into the room.

My guest today has some thoughts on the merits, and some limitations, of VEIS. Eric Dreiman is a captain with the Indianapolis Fire Department. He’s been a firefighter for 25 years and he’s presented at most of the major fire conferences around the country.
