本标准提供了通过职业安全和健康管理体系中的设计概念进行预防的指南。通过应用这些概念，与职业危害和风险有关的决策可以纳入工作场所、工具、设备、机械、物质和工作流程的设计和重新设计过程，包括其施工、制造、使用、维护和最终处置或再利用。本标准为生命周期评估和设计模型提供指导，该模型在设施、工艺或产品的整个生命周期内平衡环境和职业安全与健康目标。 图1展示了系统生命周期阶段的一个示例。

This standard provides guidance on including prevention through design concepts within an occupational safety and health management system. Through the application of these concepts, decisions pertaining to occupational hazards and risks can be incorporated into the process of design and redesign of work premises, tools, equipment, machinery, substances, and work processes including their construction, manufacture, use, maintenance, and ultimate disposal or reuse. This standard provides guidance for a life-cycle assessment and design model that balances environmental and occupational safety and health goals over the life span of a facility, process, or product. Figure 1 illustrates an example of the lifecycle phases of a system.
