(Normative Appendix) Instructions for Correct Use
A.1 The purpose of hygienic design of industrial enterprise construction projects is to implement the Law of the People's Republic of China on Prevention and Control of Occupational Diseases, adhere to the hygienic policy of "prevention as the mainstay, combining prevention and treatment", and implement the "pre-prevention" system to control occupational hazards at their source. "Pre-prevention" system to ensure that the design of industrial enterprise construction projects in line with health requirements.
A.2 The scope of application of the provisions of this standard covers all employers under the Occupational Disease Prevention and Control Law, including both enterprises, institutions and individual economic organizations. The construction period lasts for several years or the construction scale is large, there are a variety of occupational disease hazards and hazards of construction projects or temporary industrial enterprise design due to construction and other special needs, or the overall layout of the industrial park can refer to this standard.
A.3 Industrial enterprise construction project health design should follow the prevention and control of occupational disease hazards countermeasures. Prevention and control measures of occupational disease hazards include the control of occupational disease hazards occurring sources, transmission routes, contact with three aspects. The control principles and priority measures for the occurrence sources are: substitution, change of process, confinement, isolation, wet operation, local ventilation and maintenance management; the control countermeasures and priority measures for the spreading pathways are: cleaning, comprehensive ventilation, confinement, automated remote operation, monitoring and maintenance management; the control principles and priority measures for the contactors are: training and education, labor organization and management, individual medical supervision, equipped with personal protective equipment and maintenance management, etc.
A.4 The hygiene designers of industrial enterprises should learn and familiarize themselves with occupational hygiene related laws, regulations and standards in various ways, and understand the knowledge of prevention and control of occupational diseases, and carry out the hygiene design of industrial enterprises according to the results of evaluation of occupational disease hazards.
A.5 of the standard provisions of the implementation of the strict degree of words, the following writing style:
A.5.1 indicates very strict, must be done in this way can not be used: the positive word is generally used "should be", the negative word is generally used "should not be A.5.2 Words indicating a general situation: "shall" is generally used in the positive case and "shall not" in the negative case. A.5.2 Words indicating that this should be done in general, but that it would be difficult to make it mandatory: use "should try" or "as far as possible". A.5.3 To indicate that options are permitted, and under certain conditions, this can be done, use "may".
A.5.4 allows a little choice. When the conditions permit, the first should be done with the word: the positive word is generally used "appropriate" or "general", the negative word is generally used "should not".

A.8 The hygienic requirements for the intensity (concentration) of occupational disease hazards in the workplace are given in GBZ2.1, 2.2 and this standard respectively. The limit values for the intensity (concentration) of occupational disease hazards in the workplace are called occupational exposure limits in the workplace, and the intensity of some of the physical factors that are retained for the time being in this standard are called hygienic limits and will be incorporated into GBZ2.2.1 at an appropriate time. Time to incorporate GBZ2.1 or GBZ2.2.
