![]() Hartin explains that humans have been "putting the wet stuff on the red stuff" for centuries, without really analyzing the effects. What's been overlooked is the fact that the invisible gases produced in a fire can be much more dangerous than any flame. Especially in enclosed spaces, these gases tend to become superheated, flammable, and highly mobile. The result: backdrafts, flashovers, and gas explosions - the three main varieties of so-called extreme fire behavior. Every year, scores of firefighters around the world die because they've been trained to deal with this volatile mix of physics and fire gases by using an old-fashioned strategy: duck. Hartin thinks it's time for a change. He's the first fire chief in the US to embrace a tactic known as 3-D firefighting - 3-D because it takes into account the gases that fill a room, not just the surfaces of the structure on fire. Using thermal-imaging equipment, firefighters gauge the thermodynamics of a blaze and then attack both the seen and unseen elements using split-second pulses of fog. In Sweden and Britain, where it is now part of the official firefighting method, 3-D has led to a more than 50 percent drop in fatalities caused by extreme fire behavior. http://www.wired.com/wired/archive/1...ght&topic_set= |

They should do that with EQ prone and past know areas too.
