New fire-resistant design protects critical monitoring equipment from wildfires

During Australia's 2019–2020 Black Summer bushfires, at least 17 water monitoring stations were destroyed, causing weeks of lost environmental data and reducing the ability of emergency agencies to monitor drinking water quality, flood risks, and ecosystem recovery. As wildfires become more frequent and severe, protecting this critical infrastructure is becoming increasingly important.

Researchers from the University of Melbourne have now developed a practical and cost-effective solution to help water monitoring equipment survive future wildfires.

The team designed and tested fire-resistant instrumentation cabinets and cable conduits using commercially available insulation materials. "In a series of laboratory experiments, the equipment was exposed to intense radiant heat and direct flames that simulated wildfire conditions," shares lead and corresponding author Alexander Filkov. "Our design successfully kept internal temperatures below the critical operating limit for sensitive electronics, demonstrating that relatively simple modifications can dramatically improve wildfire resilience."

Notably, the monitoring equipment provides essential information before, during and after wildfires. "When these systems fail, emergency agencies lose valuable data needed to understand fire impacts, protect drinking water supplies, and support community recovery," says Filkov.

While the study focused on water monitoring stations, the team's findings have much broader applications. "The same protection principles could be used to improve the resilience of many types of critical infrastructure in fire-prone landscapes, including environmental sensors, communication systems, power networks, and other remote monitoring equipment," Filkov explains.

The researchers hope their recommendations will help government agencies and infrastructure managers better prepare for future wildfires and maintain the essential services communities rely on when they are needed most.
