Abstract

A young, healthy man wore the selected protective clothing and double gloves, which met the requirements of EN 511 standard. The selected manual tasks (e.g., Valpar Component Work Samples 1 - VCWS 1 Small Tools (Mechanical) (Bases of Virginia, LLC, USA)) were performed in a climatic chamber at low temperature (-1 degrees Celsius; 30.2 degrees Fahrenheit).Before entering and after exiting the chamber, changes in finger temperature and blood volume were determined using an infrared thermographic camera and plethysmograph. A decrease in both finger and hand temperature was observed after exposure to cold. In conclusion, the impact of low environment temperature (1h exposure) on the reduction of finger and hand skin temperature was significant. Even properly selected protective gloves, allowing for simultaneous performance of manual tasks, did not prevent the decline in hand and finger temperature. The low environment temperature (1h exposure) has a negative effect on hand and finger skin temperature, despite the use of appropriately selected protective gloves.

低温下双手套对手部温度和血容量变化的影响:个案研究

一名年轻、健康的男子穿着选定的防护服和双手套，符合EN 511标准的要求。选定的手工任务(例如，Valpar组件工作样品1 - VCWS 1小型工具(机械)(弗吉尼亚有限责任公司基地，美国))在低温(-1摄氏度;华氏30.2度)。使用红外热像仪和容积描记仪测定进入和离开腔室前后手指温度和血容量的变化。暴露于寒冷环境后，手指和手的温度均有所下降。综上所述，低环境温度(暴露1h)对手指和手部皮肤温度降低的影响是显著的。即使选择正确的防护手套，允许同时执行手工任务，也不能防止手和手指温度的下降。低环境温度(暴露1小时)对手部和手指皮肤温度有负面影响，尽管使用了适当选择的防护手套。
