Abstract

In order to reduce firefighters' heat stress and improve fire rescue efficiencyꎬ effects of cooling garments on thermoregulation of firefighters were investigated. Three categories of garments were set under high temperature (35 °C)ꎬ including basic clothing (short sleeves and shorts)ꎬ protective clothing (basic clothing and protective clothing)ꎬ and cooling garmments (basic clothingꎬ protective clothing and cooling garmments)ꎬ and typical thermal responses of participants during exercise and rest phases were measured for these cases respectively. The results show that protective clothingꎬ compared to basic oneꎬ leads to a significant increase in skin temperatureꎬ core temperatureꎬ heart rate and sweating rateꎬ and a decline in sweat evaporation rate. Cooling garmments can effectively attenuate above ̄mentioned increasesꎬ and also further reduce sweat evaporation rate. Their cooling effects decrease over time and almost disappear after 40 minutes of workꎬ or they may even increase thermal and physiological burden of firefighters.

高温下冷却服对消防员热反应的影响

为了减轻消防员的热应激，提高消防救援效率ꎬ研究了冷却服对消防员体温调节的影响。在高温(35°C)下设置三种服装ꎬ，包括基本服装(短袖和短裤)ꎬ防护服(基本服装和防护服)ꎬ和冷却服(基本服装ꎬ防护服和冷却服)ꎬ，并分别测量这些情况下参与者在运动和休息阶段的典型热反应。结果表明，防护服ꎬ与基本防护服相比ꎬ导致皮肤温度ꎬ核心温度ꎬ心率和出汗率ꎬ显著升高，汗水蒸发率下降。降温衣可以有效地减弱上述增加ꎬ，并进一步降低汗水蒸发率。随着时间的推移，它们的冷却作用逐渐减弱，在工作40分钟后几乎消失ꎬ甚至可能增加消防员的热负担和生理负担。
