Abstract:
Objective To conduct a survey on the status of noise hazards in Tianjin in 2020, to analyze the main distribution characteristics of noise hazards, and to put forward corresponding preventive and control measures. Methods A unified questionnaire was used to investigate the city-wide enterprises with more than 5 employees, normal production and operation, and noise hazards. The χ2 test was used to analyze the survey results. Results There were 8 560 enterprises with noise hazards, which were concentrated in the five outer suburban districts, the four districts around the city and the Binhai New Area, mainly small and medium-sized enterprises. Totally, 223 800 people were exposed to noise. The rates of noise hazard detection and physical examination of workers were 25.88% and 17.66%, and the rate of over standard detection and the rate of abnormal physical examination were 13.09% and 1.62%, respectively. The differences in noise detection rate, over standard detection rate and physical examination rate were significant in different administrative regions, enterprise scales and industries. The detection rate and physical examination rate of enterprises in the five outer suburban districts, micro-scale enterprises, and paper products industries were the lowest, while the rate of exceeding standards was the highest in the railway, shipping, aerospace and other transportation equipment manufacturing industries. Conclusion Noise is a common occupational hazard in enterprises in Tianjin. There are a large number of people who are exposed to noise. The detection rate and physical examination rate of noise are at a low level. Individual industries have a high rate of exceeding the standard. The current situation of noise hazard prevention and control is not optimistic. It is recommended to pay attention to it and take effective intervention measures.
