p) special industries such as pharmaceuticals, biology and food processing shall, on the basis of complying with this standard, also formulate supporting standards conforming to this standard according to the characteristics of the industry;

Annexes A and B of this standard are normative.

This standard was proposed by the Occupational Health Standards Committee of the Ministry of Health.

This standard was approved by the Ministry of Health of the People's Republic of China.

1 Scope

This standard specifies the basic hygienic requirements for the site selection and general layout, workplaces, work-related welfare facilities and emergency rescue of industrial enterprises.

This standard is applicable to the hygienic design and occupational disease hazard assessment of new construction, reconstruction, expansion, technical renovation and technology introduction projects of industrial enterprises (hereinafter collectively referred to as construction projects).

The hygienic design and occupational disease hazard assessment of construction projects of public institutions and other economic organizations, the design of temporary industrial enterprises needed for various special reasons where the construction period of a project lasts several years or the construction scale is relatively large, and the general layout of industrial parks, etc. may be implemented with reference to this standard.

3 Terms and definitions

The following terms and definitions apply to this standard.

4 General principles

4.1 The design of construction projects of industrial enterprises shall implement the Law of the People's Republic of China on the Prevention and Control of Occupational Diseases, adhere to the health work policy of "putting prevention first and combining prevention with control", implement the "prior prevention" control system for occupational disease hazards, and ensure that the design of construction projects of industrial enterprises meets hygienic requirements.

4.2 The design of construction projects of industrial enterprises shall give priority to new technologies, new processes, new materials and new equipment favourable to protecting the health of workers, and shall restrict the use of or eliminate processes, technologies and materials with serious occupational disease hazards; for occupational hazards such as industrial dust, industrial toxicants, industrial noise and high temperature that cannot yet be completely eliminated in the production process, comprehensive control measures shall be taken so that the occupational hazards in the workplace meet the requirements of the national occupational health standards, and damage to the health of workers by occupational hazards shall be prevented.

4.3 Designers undertaking the hygienic design of industrial enterprises shall understand the laws, regulations and standards related to occupational health and the knowledge of occupational disease prevention and control, and shall master the occupational hazards used in and present in the construction project, the distribution of the hazards, the characteristics of their toxic effects and the relevant prevention and control technologies.

4.4 For construction projects that may generate occupational disease hazards, the occupational disease hazard protection facilities shall be designed, constructed and put into production and use simultaneously with the main project. The feasibility study report prepared at the feasibility study stage shall include contents related to occupational health, and a pre-assessment of occupational disease hazards shall be carried out; the preliminary design prepared at the design stage shall include a special chapter on occupational health, and for construction projects with serious occupational disease hazards a special design chapter on occupational disease hazard protection facilities shall also be prepared.

4.5 The occupational health management organization and staffing shall be designed according to the nature and scale of production of the industrial enterprise, the degree (intensity) of occupational disease hazards, the number of workers, etc., taking ergonomic principles into account. For staffing, reference may be made to Table A.1 of Annex A.

4.6 The project budget design shall include funds for occupational disease prevention and control.
