Existing industrial enterprises can be appropriately relaxed when they temporarily fail to meet the standard after efforts, but it shall not exceed 90 decibels For the types of work that are exposed to noise for less than eight hours a day, the noise standard can be relaxed accordingly depending on the type of enterprise and conditions.
Workers in the noise environment allowable continuous noise for:
1, workers in the noise environment for eight hours a day, the allowable continuous noise A sound level of 90 decibels;
2, every time to reduce the time by half, the sound level can be increased by 3 decibels, but in any case is not permitted to exceed 115 decibels.
Noise health standards are as follows:
1, in order to implement the production safety and "prevention-oriented" policy, to prevent the hazards of noise in industrial enterprises, to protect the health of workers, and to promote the development of industrial production and construction, the formulation of this standard;
2, this standard applies to the industrial enterprises in the production workshop or workplace (impulse sound). Production workshops or workplaces (except impulse sound);
3, this standard by the people's government at all levels of health, labor protection authorities to supervise the implementation of;
4, this standard by the Chinese people *** and the State Ministry of Health and the State General Administration of Labor is responsible for the interpretation of;
5, industrial enterprises, production workshops and workplaces of the workplace noise standard of 85 decibels. Existing industrial enterprises may be appropriately relaxed when they temporarily fail to meet the standard after efforts, but it shall not exceed 90 decibels;
6. For the types of work that are exposed to noise for less than eight hours a day, the noise standard may be relaxed accordingly according to the types and conditions of the enterprises according to Tables 1 and 2;
7. The method of detecting the industrial noise shall be carried out according to the "Norms for Detecting the Noise in Industrial Enterprises"
8. The noise standard for the Noise-generating production processes and equipment, new technologies, new processes, new equipment, new materials, as well as mechanization, automation, confinement measures, low-noise equipment and processes instead of strong sound equipment and processes, from the source of the root of the noise;
9, new (including the introduction of the project), expansion and reconstruction of industrial enterprises must be the control of the noise of the facilities and the main project at the same time design, construction, and put into production at the same time. Construction, put into operation at the same time. The competent departments must work together with the industrial enterprises in the provinces, municipalities, autonomous regions, health, labor and relevant departments to rationally select the site, carefully review the design, do a good job of completion and acceptance, strict control. No health, labor departments to sign and seal, not allowed to construction and put into operation;
10, in the existing industrial enterprises, where the noise exceeds the provisions of this standard production workshops and workplaces, must take effective control measures to meet the requirements of this standard in a timely manner;
11, the machinery manufacturing sector, in order to improve the quality of products in the product standards should be in the noise of the health standard requirements.
In summary, we can be based on the above content for industrial noise health standards how many decibels to understand the problem. Enterprise work noise should not exceed 85 decibels, industrial enterprises, production workshops and workplaces in the workplace noise standards for 85 decibels. Noise is harmful to the human body is systemic, especially in the workplace noise, may also cause pathological changes, so factories and enterprises must issue personal protective equipment to protect the health of workers.
Legal basis:
"Chinese People's **** and State Environmental Noise Pollution Prevention and Control Law," Article 23
Industrial noise emissions to the surrounding living environment in the urban area shall comply with the state regulations of the industrial enterprise factory boundary environmental noise emission standards.
