Investigation on occupational health work status of enterprises located in Jinshan Industrial Zone in Shanghai

Objective To investigate the status of occupational hazards, prevention and control of occupational disease, and occupational health management of enterprises located in Jinshan Industrial Zone of Shanghai; To explore the appropriate model of occupational health service and supervision, in order to protect the health rights and interests of workers.

Methods Totally 87 enterprises were investigated and their basic information, data on management organization and staff, occupational hazards, protective facility, personal protective equipment, occupational health surveillance and training practice were collected.

Results Among these enterprises, 69 were small-scaled and 56 were privately owned. In 64 enterprises (73.56%), the workers exposed to occupational hazards widely, including dust, noise, heavy metals, hydrocarbons, esters, ketones, and acid-base. The examination showed that 92.14% samples were lower than the national exposure limits, but It was obvious that 65.00% sampling areas were arranged unreasonably while the occupational hazards were monitored. The occupational health surveillance rate was 76.99% among workers exposed to hazards, but no workers were diagnosed with occupational disease.

Conclusion There were some problems in these enterprises. Among them, not all occupational hazards were identified and monitored and occupational health surveillance rate was low. There were not enough professionals or mangers on occupational health work. Both administrative supervision and technical support should be reinforced to improve occupational health work in industrial zone.
