Thanks to www.FlowPathManagement.com and www.isgfire.com for this great video
The presence of modern fuels in our society has changed the time to flashover rates at alarming levels. As seen from the UL flashover comparison tests between legacy vs. modern fuels, the time to reach flashover is drastically reduced. Not only are the fuels a major consideration but the room (compartment) characteristics. Ceiling height, compartmentalization, fuel characteristics and arrangement are only a few worth naming. In this video, watch as the love seat in the center of the room explosively ignites and sets off a series of events that result in a flashover within 1:28.
The question of the day.. After watching this video from our recent class, do you feel you and your crew can crawl fast enough out of a such an extreme fire event? In this room, the ceiling height was 15′ high tapering to a 8′ ceiling height (cathedral ceiling). The fuel package consisted of 3 pallets , one sofa, and one love seat situated in the room. The taking of the front windows takes place prior to flashover as this fire goes from vent limited to bi-directional in seconds. If your crew was searching this room or even advancing an attack line and the failure of the windows occurs or a outside vent occurs how fast would you be able to react and escape?
The intention of Flow Path Management is to focus on how we can make our working area safe for our operations, We must learn more on preventing firefighters from being caught in flashovers! Make your fire corridor escapable through thermal imaging Go..No..Go.. Test. and surface cooling the environment prior to entering. Our next video will focus on the Go..No..Go.. test!
