[目的]为保障劳动者职业健康与安全,对燃气-蒸汽联合循环发电类工程项目可能存在的职业病危害因素进行辨识,提出相应的职业病防护措施。[方法]收集相关资料,采用工程分析法、文献研究法等进行定性分析。[结果]该类工程存在噪声、甲烷、高温、氯、盐酸、氢氧化钠、氨、工频电场等职业病危害因素,属于职业病危害较重项目。[结论]建议该类工程设计与施工阶段应考虑采取控制职业病危害的防尘、防毒、防噪等方面措施,确保工程运行时现场劳动者的职业健康与安全。 [Objective] In order to protect the occupational health and safety of laborers, the possible hazard factors of occupational diseases in gas-steam combined cycle power generation project were identified and relevant occupational disease protection measures were put forward. [Method] The relevant information was collected, and the qualitative analysis was carried out by engineering analysis method and literature research method. [Result] There were some occupational hazards in such projects such as noise, methane, high temperature, chlorine, hydrochloric acid, sodium hydroxide, ammonia and power frequency electric field, which were serious occupational hazards. [Conclusion] It is suggested that measures such as dust control, anti-virus and anti-noise to control occupational hazards should be taken into account during the design and construction phase of such projects so as to ensure the occupational health and safety of on-site workers during project operation.
