Abstract
Objective To identify the occupational hazards in conducting a renovation project by a company's micro-nano photonic integration center,and analyze the critical control points.Methods On-site investigation and inspection were car-ried out for qualitative and quantitative evaluation of the occupational hazards in conducting the renovation project in 2022.Results The main occupational hazards identified include sulfuric acid,ammonia,nitrogen oxide,hydrochloric acid,sodium hydroxide,chlorine,sulfur hexafluoride,hydrogen peroxide,hydrogen fluoride,trichloroethylene,isopropanol,phosphoric acid,acetone,nickel and its compounds,tin dioxide,and noise.The levels of toxic substances exposure were lower than the occupational exposure limits.Moreover,the noise exposure level was also lower than the occupational expo-sure limit.Conclusion There are many occupational hazards in implementing this project,and the critical control points for controlling toxic substance exposure involve the production process,equipment repair and maintenance,and accident emergency rescue.The company should strengthen the management of these control points so as to prevent the occurrence of occupational hazards such as poisoning and burns.
