本文件定义了为符合ISO 14300中定义的安全政策而实施的安全计划和技术安全要求？2.其目的是保护飞行人员和地面人员、运载火箭、相关有效载荷、地面支持设备、公众、公共和私人财产以及环境免受与空间系统有关的危害。ISO 14620描述了发射场的操作？2和ISO 14620中的飞行安全系统？3.安全政策通过实施系统安全计划来应用，并得到风险评估的支持，风险评估可总结如下。a)通过反复执行系统安全分析，识别并逐步评估具有潜在危险故障影响的危险特性（系统和环境危害）和功能。b)与系统特性和功能故障相关联的潜在危险后果经受危险降低序列，由此:从系统设计和操作中消除危害；危害最小化；和应用并验证危害控制。c)逐步评估应用消除和减少危害过程后仍然存在的风险并进行风险评估，以便:显示符合安全目标；支持设计行业；识别风险贡献者并对其进行排名；支持项目资源的分配以降低风险；评估降低风险的进展；和支持安全和项目决策过程（如豁免批准、剩余风险接受）。d)正式验证所应用的危害和风险控制措施的充分性，以支持安全性验证和风险验收。e)安全合规性由项目和从相关机构获得的安全批准进行评估。

This document defines the safety programme and the technical safety requirements that are implemented in order to comply with the safety policy as defined in ISO 14300？2. It is intended to protect flight and ground personnel, the launch vehicle, associated payloads, ground support equipment, the general public, public and private property, and the environment from hazards associated with space systems. Launch site operations are described by ISO 14620？2 and flight safety systems in ISO 14620？3.

The safety policy is applied by implementing a system safety programme, supported by risk assessment, which can be summarized as follows.

a) Hazardous characteristics (system and environmental hazards) and functions with potentially hazardous failure effects are identified and progressively evaluated by iteratively performing systematic safety analyses.

b) The potential hazardous consequences associated with the system characteristics and functional failures are subjected to a hazard reduction sequence whereby:

1. hazards are eliminated from the system design and operations;
2. hazards are minimized; and
3. hazard controls are applied and verified.

c) The risks that remain after the application of a hazard elimination and reduction process are progressively assessed and subjected to risk assessment, in order to:

1. show compliance with safety targets;
2. support design trades;
3. identify and rank risk contributors;
4. support apportionment of project resources for risk reduction;
5. assess risk reduction progress; and
6. support the safety and project decision-making process (e.g. waiver approval, residual risk acceptance).

d) The adequacy of the hazard and risk control measures applied are formally verified in order to support safety validation and risk acceptance.

e) Safety compliance is assessed by the project and safety approval obtained from the relevant authorities.
