预先危险性分析法(PHA)是一种常用的定性安全评价方法,但由于其对危险等级的判定没有量化的指数作为依据,因而在实际应用中往往不免存在主观臆断的因素。然而基于风险矩阵(Risk Matrix)的预先危险性分析评价方法,使PHA评价法可以量化评判指数,使安全评价更加科学合理。
The pre-hazard analysis (PHA) is a commonly used method of qualitative safety assessment. However, due to its non-quantified index of the determination of the hazard level, PHA can not be subjectively assumed in practice. However, based on the Risk Matrix pre-hazard analysis and evaluation method, the PHA evaluation method can quantify the index of judgment and make the safety assessment more scientific and reasonable.
