本文件概述了执行系统安全的标准实践。系统安全 本文定义的实践提供了评估已识别风险的一致方法。事故风险 必须进行识别、评估，并将其降低到合理可行的最低水平。这个 事故风险必须得到相关部门的认可，并符合联邦（和州）的规定， （如适用）法律法规、行政命令、条约和协议。程序 与减轻灾害风险相关的贸易研究必须考虑任何生命周期的总成本。 决定本文件旨在用作复杂项目的项目招标要素之一 需要对安全危害和缓解措施进行系统评估的系统。这个 管理当局可在招标书和系统规范中确定具体的系统 开发商应满足的安全工程要求。这些可能包括风险评估 以及验收标准、独特的分类和认证，或减少事故的需求 这是他们项目的独特之处。满足项目特定要求的其他信息如下: 位于附录中。

This document outlines a standard practice for conducting system safety. The system safety practice as defined herein provides a consistent means of evaluating identified risks. Mishap risk must be identified, evaluated, and mitigated to a level as low as reasonably practicable. The mishap risk must be accepted by the appropriate authority and comply with federal (and state, where applicable) laws and regulations, executive orders, treaties, and agreements. Program trade studies associated with mitigating mishap risk must consider total life cycle cost in any decision.This document is intended for use as one of the elements of project solicitation for complex systems requiring a systematic evaluation of safety hazards and mitigating measures. The Managing authority may identify, in the solicitation and system specification, specific system safety engineering requirements to be met by the Developer. These may include risk assessment and acceptance criteria, unique classifications and certifications, or mishap reduction needs unique to their program. Additional information in meeting program specific requirements is located in the Appendixes.
