North Carolina State University researchers found that four new designs for shelters to protect firefighters trapped in wildfires could increase the survival time inside the shelter compared with the current industry standard. In lab simulations of wildfire burn-overs—where a wildfire sweeps over a group of trapped firefighters or equipment—temperatures inside the shelters remained within survival limits for longer, and the shelters took longer to break open.
