Do you know exactly how vertical ventilation works?

Depending on your level of experience, you may think you do, but you still might not have a really solid understanding of why it works. Simply cutting a random 4x4-foot hole in the roof won't do the job in all cases.

My guest today has a good deal of experience as a firefighter, but he admits that, until he saw a live fire test, he misunderstood how cutting a hole in the roof affects the fire.

We’ll talk about that, as well as when it’s the best time to vent the roof, how dangerous it is to work up there, how handlines can be used to move air and smoke with it, and how much training firefighters need to remain proficient in roof operations.

Nicholas Papa is a 17-year veteran of the New Britain, Connecticut, Fire Department, where he’s a captain. He became a firefighter in 2003, volunteering for a neighboring suburb until he was hired by New Britain.
