Abstract:

To enhance the safety management level of new energy projects in high-altitude areas under low-oxygen and low-temperature conditions, a photovoltaic project on the Qinghai Xizang Plateau was taken as the research background. By testing the blood oxygen concentration and heart rate of sample groups, the study investigated the changes in altitude sickness symptoms among newly arrived personnel at the plateau and those who had acclimatized for over a month, as well as the occurrence of hypothermia, frostbite, and colds. The impact on the safety and health of construction personnel who are native to the plains was analyzed. The results show that construction personnel at an altitude of 4 854.5 m have already experienced mild hypoxia and abnormal heart rate. Among newly arrived project personnel, over 80% have reported difficulties in falling asleep, headaches/dizziness, and difficulty in eating/a significant decrease in appetite. Even after acclimatizing on-site for over a month, as many as 88.51% still have experienced impaired sleep quality, and around 50% have reported decreased memory and reduced responsiveness as newly developed issues. When the average temperature falls below 5 ℃, over 50% of the personnel develop colds. Despite protective measures, hypothermia still causes frostbite on the hands, feet, and ears of some personnel. The low oxygen and temperature conditions on the plateau have impacted the safety and health of construction personnel. Suggestions for strengthening site access control, improving process management, and enhancing emergency response measures are proposed.
