Typically, hazards identified in the PHA are further assessed with other risk management tools such as those in this section.

通常情况下, PHA确定危害会通过其他风险管理工具(如本工具)进行进一步评估。

Potential Areas of Use(s) PHA might be useful when analyzing existing systems or prioritizing hazards where circumstances prevent a more extensive technique from being used.

潜在用领域在分析有系统或确定危险优先等级时（当情况不用更广泛技术时），PHA 可能会很有用。

PHA is most commonly used early in the development of a project when there is little information on design details or operating procedures; thus, it will often be a precursor to further studies.

PHA 最常用于项目开发早期阶段, 当时关于设计细或操作程序信息很少;因此, 它通常将是进一步研究前奏。
