The degree of safety achieved in a system depend on the importance it is given by system designers,manager ,and operator .the effort necessary to assure that sufficient emphasis is placed on system safety are often organized into formal program .the objective of such program are to recognize ,evaluate ,and control system hazard as early in the life cycle as possible .adequate safety input during the initial phase is the key to produce an inherently safe system .effective system safety program also eliminate the schedule delay and costly change that often result in system that do not have adequate safety planning .系统安全水平取决于系统设计者、经理及系统操作人员赋予系统的重要性,确保强调系统安全的重要性要经常加入到正式的程序中,这些程序的目标是在系统生命周期中尽快的识别、评估和控制系统风险.adequate在初始阶段是生产的关键一种固有的安全体系.在系统最初阶段保证足够的安全投入是实现本质安全化的关键。高效的系统安全程序也消除了日程安排的延迟和代价惨重的的变化,这些变化通常会导致系统没有足够的安全计划。 |
