The worst flames in firefighting are the ones you don't see coming. In the midst of the chaos of a burning building, it's difficult to spot the warning signs of impending flashover -- a deadly fire phenomenon in which nearly all combustible items in a room spontaneously ignite. Flashover is one of the leading causes of firefighter deaths, but new research suggests that artificial intelligence (AI) could provide much-needed forewarning to first responders. Researchers at the National Institute of Standards and Technology (NIST), Hong Kong Polytechnic University and other institutions have created a Flashover Prediction Neural Network (FlashNet) model to predict deadly events seconds before they occur. In a recent study that was published in Engineering Applications of Artificial Intelligence, FlashNet outperformed existing AI-based flashover forecasting tools, boasting an accuracy of up to 92.1% across more than a dozen popular residential floorplans in the US.

In firefighting, the worst flames are the ones you don't see coming. Amid the chaos of a burning building, it is difficult to notice the signs of impending flashover -- a deadly fire phenomenon wherein nearly all combustible items in a room ignite suddenly. Flashover is one of the leading causes of firefighter deaths, but new research suggests that artificial intelligence (AI) could provide first responders with a much-needed heads-up. Researchers at the National Institute of Standards and Technology (NIST), the Hong Kong Polytechnic University and other institutions have developed a Flashover Prediction Neural Network (FlashNet) model to forecast the lethal events precious seconds before they erupt. In a new study published in Engineering Applications of Artificial Intelligence, FlashNet boasted an accuracy of up to 92.1% across more than a dozen common residential floorplans in the U.S. and came out on top when going head-to-head with other AI-based flashover predicting programs. Flashovers tend to suddenly flare up at approximately 600 degrees Celsius (1,100 degrees Fahrenheit) and can then cause temperatures to shoot up further.
