Abstract:
Objective:To identify the process nodes and types of dust existing during subway construction, evaluate the occupational health risk assessment, analyze the key control points, and provide technical basis for occupational health management.Methods:From August 2017 to December 2018, the field occupational health survey method was used to investigate the whole construction period of subway, and the occupational health risk assessment method was used to assess the degree of dust hazard, and the consistency of the assessment results of ICMM, UQ and MLSP methods were compared.Results:The dust in the operation site exists in multiple nodes of the construction cycle, and the operators were exposed to a variety of dust at the same time. Concrete workers and other jobs were key control posts. The risk level assessed by ICMM method was relatively higher than that by UQ method and MLSP method, the latter two results were relatively close.Conclusion:The three occupational health risk assessment methods are all suitable for the site risk assessment without occupational monitoring data, and UQ method has better applicability to the construction industry.
