Failures and their effects are investigated during the design phase,but it is only when the craft is operating that its safety can be truly established with the multitude of possibilities of machinery layouts,and the wide variety of directional control devices and their configurations,it is impossible to rigid safety criteria.Each design must be adopt considered on its own merits and thoroughly analyzed.
在设计阶段就要研究失败以及由此带来的影响,但是只有当工艺产品开始运行的时候,建立在机械布局的多种可能性上及各种各样的定向控制装置及其配置之上,安全性才可能得到保障.想要严格规范安全标准是不可能的,每一个设计都必须根据自身情况深思熟虑并彻底分析.
