Hydraulic Ventilation in Increasingly Poor Atmospheres

摘要

THE JERSEY CITY (NJ) FIRE DEPARTMENT does a great deal of hydraulic venting. Venting out a compartmentalized room-and-contents fire is an automatic tactic post-knockdown. Getting to the nearest vent point, staying about six feet back, and opening a mid to narrow fog stream is a time-tested way to increase visibility; finish up an attack; accelerate post-control overhaul; and, most importantly, remove an unsustainable atmosphere from an area where potential victims can still be uncovered. To that point, I'd like to address some instances of proper and aggressive hydraulic ventilation at structural fires and why I consider it important.
