Device Developed to Prevent Firefighter Heatstroke by Cooling Palms

South Korea has developed a new cooling device designed to rapidly reduce body temperature for firefighters engaged in prolonged suppression activities during heatwaves. The National Fire Agency's National Fire Research Institute announced on July 28 that it has completed the patent registration for its 'Thermoslectric Element-based Body Cooling Device Technology.' The institute plans to transfer this technology to private companies for commercialization.

The device utilizes a combination of thermoelectric elements and circulating cold water to cool the palms of the hands. This method leverages the physiological characteristic that increased blood flow to the palms helps dissipate body heat. When a firefighter's core body temperature rises to between 38.5 and 39.5 degrees Celsius, using the device for about five minutes can reportedly restore it to normal levels.

Fire officials highlighted the device's practicality, noting that it can be used even in emergency situations where firefighters cannot remove their protective gear. The design allows for heat reduction simply by placing the palm on the cooling device. The National Fire Research Institute intends to test the device's real-world performance through pilot projects in recovery support tents and vehicles.

"As heatwaves become commonplace, preventing heat-related illnesses for firefighters on duty is a critical task," said Kim Yeon-sang, head of the National Fire Research Institute. "We will continue to develop and commercialize technologies that can be immediately utilized in the field to contribute to improving firefighter safety."
