GB/T 2893.1—2004 is intended to be divided into two parts: Part 1: Design principles for safety signs in workplaces and public areas: Part 2: Design principles for product safety labels. GB/T 2893.1—2004
This part is the first part of GB/T2893, and is modified to adopt ISO3864-1:2002 Graphical symbols, safety colors and safety signs, Part 1, Design principles for safety signs in workplaces and public areas (English version). For ease of use, this part has made the following editorial changes:
- Changed some expressions applicable to international standards to expressions applicable to Chinese standards:- Replaced terms 3.4 and 3.6 with terms with the same meanings in Chinese national standards;- Coordinated the specific examples in the examples of use in Table 1 with Chinese national standards: Replaced the English in the examples in Chapter 8 with the corresponding Chinese, and made minor changes to several examples;- Deleted the foreword of the international standard:
Added reference values ​​of safety colors in the Chinese color system in the informative Appendix A. Compared with ISO 3864-1:2002, this part has the following technical differences: GI/T1000, which is not equivalent to the international standard, replaces the reference document IS07001 in the original international standard: adds the normative reference document GB/T5465.2-1996 Graphical symbols for electrical equipment; adds the normative reference document GB/T1000I (all other parts) Public information graphic symbols for signs; adds the normative reference document GB/T15565 "Graphic symbol terms"; adds the normative reference document GB/T16273 (all parts) "Graphic symbols for equipment": delete the provisions on the international standardization procedure of graphic symbols in Chapter 6 of the international standard. Appendix A of this part is an informative appendix.
This part is proposed by the China Institute of Standardization. This part is under the jurisdiction of the National Technical Committee for Standardization of Graphic Symbols. This part was drafted by China National Institute of Standardization, National Safety Supervision Bureau, Institute of Psychology, Chinese Academy of Sciences, Institute of Building Physics, China Academy of Building Research, and Fire Protection Department of Ministry of Public Security. The main drafters of this part are Chen Yongxiao, Bai Dianyi, Yang Guopo, Zhang Liang, Sun Xiuru, Zhang Shaona, and Hao Zheng. GB/T2893.1—2004
In order to make the system of conveying safety information understandable and rely as little as possible on language, it is necessary to standardize it. With the continuous growth of trade, tourism and labor mobility, it is very necessary to establish a universal way of conveying safety information. The lack of standardization of the system of conveying safety information may lead to confusion and even accidents. Publicity and education are an essential component of any system of conveying safety information. Although safety colors and safety signs are essential in any system of conveying safety information, they cannot replace the use of correct working methods, instructions, accident prevention measures and training.

Suitable for expressing the information given by the graphic symbol
The process of developing graphic symbols for safety signs in standards should start with a clear definition of the specific information to be conveyed. The sign scheme should be designed in accordance with the colors, geometric shapes and other criteria specified in this part of GB/T 2893. In the case of only one scheme, art designers should be encouraged to provide alternative schemes. According to GB/T12103, the process of selecting symbol schemes for comprehension testing should be: simplify the symbol schemes with very similar contents into one scheme among the collected symbol schemes; exclude the symbol schemes that have been tested or included in GB/T5465.2, GB/T10001, GB/T16273 and ISO7000 or IEC60417-2;
Ensure that the colors and shapes comply with the basic rules of this part; exclude the symbol schemes whose graphics are similar to or repeated with the standardized graphic symbols or graphic elements. ISO7010 gives the acceptable criteria for the standardization of safety signs. 7 Design of safety signs
7.1 General
Safety colors, contrasting colors and geometric shapes (see Chapter 5) should only be used in the following combinations to obtain five basic types of safety signs (see Figures 1 to 7).
GB/T2893.1—2004
When there is no suitable graphic symbol to express the desired specific meaning, the corresponding general sign (see Figures 1 to 3) and the auxiliary sign (see Figures 8 to 16) should be used to express the meaning. In order to contrast the safety signs and (or) auxiliary signs with the surrounding environment, it is recommended to use a lining. As shown in Figures 1 to 10, the value of the lining is 0.025 to 0.05 times the size of the geometric shape (ds, bs, us, and the rectangular sign uses the size as). For practical reasons, d is equal to dsb and bs within a deviation of 5%. The brightness of the lining of the translucent safety sign should not be greater than the brightness of the contrasting color. 7.2 Prohibition signs
Prohibition signs should comply with the design requirements given in Figure 1. 45
The color of the sign should be:
