TODD: Federal officials tell us it only takes about a minute - and-a-half for what they call a flashover -- for the cabin to be engulfed in smoke, as shown in this simulation.
But Lentini says science proves these pour patterns were really caused by a recently accepted phenomenon called flashover, the point, when a fire in a room becomes a room on fire.
But tests conducted in the 1990s showed that fires can hit the point of "flashover" - when all combustible surfaces ignite at once - in under four minutes with no accelerants.
She said he (Randhir) went to test the power at about 12. 45pm when the accident, which is referred to as a flashover - the near simultaneous ignition of all combustible material in an enclosed area - occurred.
The fire in Graf's shed on Aug. 26, 1986, quickly mushroomed to intense burning known as flashover, or full involvement.
"flashover" -- meaning an unintended power surge that causes spontaneous combustion.
The firefighters had managed to pull one victim from the home and were trying to find the other person when they were caught in a "flashover,..."
Once they start dying off, there's going to be a kind of flashover thing where video games are no longer the scary, difficult niche hobby, and are regarded more in the same way as we regard TV or the internet.
Once "flashover" occurs, where the fire has ignited the room, occupants have only three to seven minutes to evacuate, Deputy Chief Frank Lamie said in an interview.
As the article says, in under two minutes, your kitchen is at risk for "flashover," which is when the surrounding objects and surfaces get to their ignition temperature and burst into flames.
