[Survey of occupational health condition in a shipyard in Guangzhou, China].

OBJECTIVE: To investigate the occupational health condition in a shipyard in Guangzhou, China, and to provide a basis for improving the working environment. METHODS: The monitoring data on occupational harmful factors in the workplace and the data on health examination of the workers were analyzed, and the occupational health condition in the shipyard was evaluated with the related occupational health standards. RESULTS: Except benzene, toluene, and electromagnetic radiation, the dust (2.02%), grinding wheel dust (3.85%), wood dust (2 out of 4 workers exceeded the standard), welding fume (16.85%), manganese dioxide (17.98%), dimethylbenzene (8.00%), and noise (53.20%) were all out of limits to different degrees. The health examination results of 2450 workers in the shipyard showed that the respiratory impairment of dust-exposed workers (3.19%) and the hearing impairment of noise-exposed workers (12.21%) were comparatively severe. CONCLUSION: The occupational health condition in this shipyard is not good. In order to protect the workers from health hazards, it is urgent and necessary to improve the working environment and strengthen the personal protective measures.

[Application of risk grading and classification for occupational hazards in risk management for a shipbuilding project].

OBJECTIVE: To investigate the application of risk grading and classification for occupational hazards in risk management for a shipbuilding project. METHODS: The risk management for this shipbuilding project was performed by a comprehensive application of MES evaluation, quality assessment of occupational health management, and risk grading and classification for occupational hazards, through the methods of occupational health survey, occupational health testing, and occupational health examinations. RESULTS: The results of MES evaluation showed that the risk of occupational hazards in this project was grade 3, which was considered as significant risk; Q value calculated by quality assessment of occupational health management was 0.52, which was considered to be unqualified; the comprehensive evaluation with these two methods showed that the integrated risk rating for this shipbuilding project was class D, and follow- up and rectification were needed with a focus on the improvement in health management. CONCLUSION: The application of MES evaluation and quality assessment of occupational health management in risk management for occupational hazards can achieve objective and reasonable conclusions and has good applicability.
