Dynamic thermal physiological response dataset of personnel under firefighting scenarios for portable monitoring device development

Dynamic thermal physiological responses of personnel under firefighting scenarios were investigated. A comprehensive dataset was established to support the development of portable monitoring devices. Controlled human subject experiments were conducted with 16 healthy participants (8 firefighters, 8 students). Effects of temperature conditions (26°C, 31°C, 36°C), clothing types (training uniform, protective clothing), and exercise modes (cycling, stair climbing) were investigated. Core body temperature, skin temperature, heart rate, and sweat volume were measured as indicators. Thermal sensation, thermal comfort, sweating sensation, and fatigue level were collected as subjective evaluations. Results showed that core temperature increased progressively with environmental temperature, which were 0.28°C, 0.36°C, and 0.43°C under 26°C, 31°C, and 36°C conditions respectively. The maximum increase reached 0.79°C under protective clothing conditions. Heart rate increased during stair climbing exercise were higher than cycling exercise. Increases were 45bpm and 17bpm respectively under 36°C conditions. Firefighters demonstrated stronger thermal adaptation capacity. Heart rate increases were approximately 27% lower than students under identical conditions. Skin temperature varied with body sites. The largest temperature increases were observed at thigh sites (3.2°C), arms showed the second (3.1°C), while lateral chest had the smallest increases (0.5°C). Arm skin temperature demonstrated the highest correlation with core temperature and showed the smallest individual differences. Strong correlations between sweat volume and body surface area were established, with R 2 values exceeded 0.91. Subjective evaluations were consistent with objective indicators. This research provides scientific basis for firefighter thermal safety protection and portable monitoring device development.
