电气和电子设备的机械结构. 通道柜安全壳. 第3部分: 操作和人身安全方面

[中文适用范围]： 本文档定义了IT机柜通道封闭结构的操作安全和个人安全要求。其目的是通过使用“可用性”和“安全”标准，为封闭结构内安装的IT设备提供物理安全。要求适用于所有操作、工作和维护程序。本文档不适用于普通人使用设施和设备的情况。此处描述的要求旨在确保授权人员能够进入并保持在该封闭结构内（作为可访问设备），并在无风险的情况下维护或升级安装在封闭结构内的系统。还应能够在任何时候（特别是在发生火灾或其他危险情况时）快速、安全地撤离封闭结构，同时将人员健康风险降至最低。涉及计算、数据处理、数据存储、建筑物保护或数据中心本身的方面不属于本文档的范围。仅考虑整合通道封闭结构后出现的额外方面。集成在数据中心内的通道封闭结构的设计和定位对以下不同方面的操作安全产生影响：a) 逃生和疏散计划；b) 逃生路线；c) 紧急出口；d) 逃生门的功能方面；e) 照明条件；f) 逃生路线的照明和标志；g) 防火保护。在本文档中，这些操作安全要求和建议均予以考虑。为了达到最高效率，在设计通道封闭结构时，应尽可能考虑所有这些要求。本文档适用于正常运行，而不适用于封闭结构的初始安装。 [外文原描述]： IEC TS 62966-3:2021 defines the requirements for operational and personal safety of aisle containments for IT cabinets. The aim is to provide physical security for the IT equipment installed in the containment using the criteria “availability” and “safety”. The requirements apply to all operational, working and maintenance procedures. This document does not apply to ordinary persons, when using installations and equipment. The requirements described herein are also intended to ensure that it is possible for authorized personnel to enter and remain in the containment (as accessible equipment) and to maintain or upgrade the systems installed in the containment without risk. It should also be possible to evacuate the containment quickly and safely at any time, especially in the event of a fire or any other hazardous situation, whilst reducing the health risk to personnel to a minimum. Aspects relating to computing, data processing, data storage, building protection or the data centre itself do not fall within the scope of this document. Only those additional aspects arising from the integration of an aisle containment are considered. The design and positioning of an aisle containment, which is integrated in the data centre, has influence on the following different aspects of operational safety: a) escape and evacuation plans; b) escape routes; c) emergency exits; d) functional aspects of escape doors; e) lighting conditions f) lighting and signposting of escape routes; g) fire protection. In this document, these operational safety requirements and recommendations are considered. To achieve the highest effectiveness, all these requirements are considered as much as possible during the design of an aisle containment. This document applies to normal operations, not to the initial installation of the containment.
