Fire isn't the only risk firefighters face - toxic, impenetrable smoke and darkness add to the dangers and slow down their progress. Clad in heavy protective gear, firefighters may also be dragging a firehose behind them and carrying a thermal imaging camera to help orient them. An EPFL team is working on a smart visor that, combined with a thermal imaging camera, will help firefighters see what’s around them in real time, even at night and in smoke. Their solution consists of placing a mini infrared camera on the helmet and incorporating a transparent screen in the oxygen mask. Thus equipped, firefighters see two images in their field of view: what their eyes see and what the thermal imaging camera records and displays in real time. This allows firefighters to move around more easily and avoid obstacles without having to interrupt the search process.
