This class reviews the past 35 years of study and implementation of positive pressure attack (PPA). Despite its proven effectiveness, it remains a point of contention and confusion within the U.S. fire service. The class ponders the question “Where do we go from here?” The class begins with the earliest tests and applications of a pressurized fire attack and ends with where the tactic now stands and what the future holds. Discussions will be anchored in several physical laws including the laws of thermodynamics, the Bernoulli principle, and the combined gas laws.
