1.1 本规程使用符号描述手动或计算机辅助设计（CAD）生成的建筑或工程图纸的安全系统和设备要求。所描述的符号包括一些已被普遍接受或已被标准编写机构（如美国国家消防协会）采用的符号。 1.2 由于图纸所需的详细程度可能会有所不同，因此不建议使用所有符号。在某些情况下，一类安全装置的通用符号可能就足够了。此外，需要在实际图纸中提供安全措施也可能表明需要使用通用符号，而不是描述正在安装的确切设备。 1.3 如果需要更高级别的细节，可以组合许多符号来创建达到所需级别的新符号。 虽然显示了一些符号的组合，但试图描述每个可能的符号组合是不切实际的。本实践的目的也是，随着行业技术水平的变化或重点的变化，符号能够不断扩展和修改。例如，很少注意安全符号中的文件安全性，因为此类要求在施工期间通常未完全满足，而是在随后制定和提供。由于这类设备大多未安装，而是“放置”的，例如家具，因此只建议使用一个符号（例如，用于文件粉碎机）。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This practice utilizes symbols to depict security systems and equipment requirements for architectural or engineering drawings that are produced either manually or by computer aided design (CAD). The symbols depicted include some symbols that have already been somewhat universally accepted or that have already been adopted by a standards-writing body, such as by the National Fire Protection Association. 1.2 It is not proposed that all of the symbols need to be utilized since the level of detail required for drawings is likely to vary. Generic symbols of a class of security device may be sufficient in some instances. Moreover, the need to provide a measure of security in the actual drawing may also suggest a need to utilize a generic symbol rather than to depict the exact device being installed. 1.3 In the event that a greater level of detail is required, it is possible to combine many of the symbols to create new symbols that achieve the desired level. While some combinations of symbols are shown, it would be impractical to attempt to depict every conceivable combination of symbols. It is also the intent of this practice that the symbols be capable of being continuously expanded and modified as the industry state of the art changes or as emphasis varies. For example, little attention is given to document security in the security symbols since such requirements are not generally fully met during construction periods but are rather developed and provided for subsequently. Since much of this equipment is not installed but is “placed,” such as furniture, there is only one symbol proposed (for example, for document shredders). 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
