As times change and research becomes more accurate, we learn more about fire behavior. And the more we learn, the faster fires get put out. With today’s construction techniques and materials, that also means a safer fireground. That’s why today’s guests worked together to write a book: “The Evolving Fireground: Research-Based Tactics.” Joining me for this episode are P.J. Norwood, a Deputy Chief Training Officer for the East Haven Connecticut Fire Department, and Sean Gray, a 21-year veteran of the fire service and a lieutenant in the Cobb County Georgia Fire Department.
