Let’s consider this in the context of our fire behavior indicators. Backdrafts present a serious threat to firefighters.There is some debate concerning whether backdrafts should be considered a type of flashover (see … Back To Basic Special Edition Fire Behavior Fire Triangle & Tetrahedron The four basic methods of extinguishing fires require the understanding of how they effect the fire triangle and tetrahe- In other words, Fire Dynamics is the study of how fires start, spread and develop. Fifteen years ago tomorrow, three members of the Fire Department of the City of New York (FDNY) lost their lives while conducting search in a three story apartment building located at 62 Watts Street in Manhattan. • Backdraft • Fire Behavior Terms • Fire Behavior Quiz Back To Basics Fire Behavior A Review of Fire Behavior and Science Special Edition .

Ed has a longstanding interest in fire behavior … Ed Hartin, M.S., EFO, MIFireE, CFO is a Battalion Chief with Gresham Fire and Emergency Services in Gresham, Oregon. Building Backdraft is more likely to occur in energy-efficient buildings … Backdraft– A backdraft is when there’s an explosion due to oxygen being let into a room full of hot gases. A backdraft is a rapid or explosive burning of superheated gasses in a fire, caused when oxygen rapidly enters an oxygen-depleted environment; for example, when a window or door to an enclosed space is opened or broken. Fire Dynamics is the study of how chemistry, fire science, material science and the mechanical engineering disciplines of fluid mechanics and heat transfer interact to influence fire behavior. When a fire is burning in an enclosed area, eventually, it burns up all of the oxygen (it’s oxidizer). Norwood at However, our understanding and communication about these important processes and phenomena are limited by lack of a common language. the relationships between fire behavior and our tactics. Our tactics have both a positive and negative impact on the fire behavior and it is up to us utilizing this small-scale fire behavior prop to outline both the positive and negative. This transient phenomenon is an example of typical catastrophe behaviour. Firefighters encounter all sorts of dangerous fire behavior in their work.

This causes hot, flammable gases to fill the room. Fire Dynamics. Backdraft at 62 Watts Street. But what exactly is a fire? Each of us faces the same processes of compartment fire development and extreme fire behavior phenomena such as flashover, backdraft, and smoke explosion. Backdraft is a fire phenomenon in which the hot gasses formed from combustion at low oxygen levels rapidly combust due to abruptly supplying abundant fresh air.
