Still Waters Posted March 22 #1 Share Posted March 22 (IP: Staff) · QUT researchers have built and tested a bushfire safe room that exceeds current Australian standards and could keep people alive or protect valuables when evacuation is no longer an option. Led by Dr. Anthony Ariyanayagam from the QUT Faculty of Engineering, the full-scale safe room was constructed at the Queensland Fire and Emergency Services (QFES) facility in Lytton and tested under simulated bushfire conditions. Built with cavity insulated light gauge steel framed walls, the roof lined externally with Autoclaved Aerated Concrete panels and internally with fire-rated gypsum plasterboards, during testing the external wall temperature reached a maximum of 958 °C at 30 mins during peak flame exposure, while internal surfaces remained under 29°C with less than 1°C rise in internal air temperatures. "In theory, people could survive in this shelter for up to two hours, but we need to test other conditions like air quality before recommending human survivability too," he said. https://phys.org/news/2023-03-bushfire-safe-rooms.html 1 Top Link to comment Share on other sites More sharing options...
