工艺危害分析的作用工艺危害分析(Process Hazard Analysis,简称PHA)是过程安全管理的核心要素,即有组织地、系统地对工艺装置或设施进行危害辨识,能够为消除和减少工艺过程中的危害、减轻事故后果提供必要的决策依据。工艺危害分析关注设备、仪表、公用工程、人为因素及外部因素对于工艺过程的影响,着重分析着火、爆炸、有毒物泄漏和危险化学品泄漏的原 The Role of Process Hazard Analysis Process Hazard Analysis (PHA) is the core element of process safety management. Organizational and systematic hazard identification of process equipment or facilities can eliminate and reduce hazards in the process , Mitigate the consequences of the accident to provide the necessary basis for decision-making. Process Hazard Analysis focuses on the impact of equipment, instrumentation, utilities, human factors and external factors on the process, focusing on the analysis of the original fire, explosion, toxicants and original hazardous chemicals
