INTRODUCTION
Tunnel boring machine (TBM) is used for constructing a tunnel. Worn out cutting tools have to be changed under difficult working conditions. Temperature is high and the work is strenuous. Work is often carried out under increased atmospheric pressure to ward off water ingress. Workers are at a very high risk.
AIM
To evaluate heat stress during hyperbaric intervention on TBM during Chennai Metro Rail construction.
METHODOLOGY
One hundred and eighty-eight miners after a thorough medical examination worked under increased atmospheric pressure for more than 45,000 man hours. Mitigating actions to protect workers by reducing temperature and increasing ventilation. Medical monitoring was done to identify and treat potential victims.
RESULTS
52° C was the highest temperature recorded. Most times work was carried out at a temperature range of 34-45° C.
CONCLUSIONS
Motivations of monetary gains, reduced working hours, and food supplements played a major role in work execution without any untoward incidence.
引言
隧道掘进机（TBM）用于建造隧道。磨损的切割工具必须在艰苦的工作条件下更换。温度很高，工作强度很大。工作通常在增加的大气压力下进行以防止进水。工人面临的风险非常高。
目的
评估钦奈地铁建设期间在TBM上进行高压干预时的热应激情况。
方法
188名矿工经过全面体检后，在增加的大气压力下工作超过45000工时。采取减轻措施，通过降低温度和增加通风来保护工人。进行医疗监测以识别和治疗潜在受害者。
结果
记录到的最高温度为52°C。大多数时候工作是在34 - 45°C的温度范围内进行的。
结论
金钱收益、减少工作时间和食物补充等激励因素在工作执行中起到了主要作用，且没有发生任何不良事件。
