本文件描述了一种人为因素工具，可供运行工厂使用，作为将人为因素原则纳入由人员操作和维护的设备设计的辅助工具。本文件中描述的人为因素原则适用于新设备设计；然而，在可行的情况下，该工具中提供的许多想法可用于改善现有电厂的运行。 本文件仅侧重于设备设计。人为错误、基于行为的安全和操作程序问题等项目不在范围内。该工具涵盖了上游生产和下游生产操作所共有的设备。与特定活动相关的设备，如钻机，没有具体说明。

This document describes a Human Factors Tool that may be used by operating plants as an aid to incorporate human factors principles in the design of equipment that will be operated and maintained by people.The human factors principles described in this document are intended for new equipment designs; however, many ideas provided in this Tool may be used to improve the operation of existing plants, where feasible. This document focuses only on equipment design. Items such as human error, behavior-based safety, and operating procedure issues are not in the scope.The Tool covers equipment that is common to both upstream producing and downstream manufacturing operations. Equipment associated with specific activities, such as drilling rigs is not specifically addressed.
