给出重大事故危害阈值的定义和主要类型.通过对国内外相关文献的分析,确定出火灾、爆炸伤害准则,并对各种常见毒物紧急暴露阈值进行比较.在此基础上,给出各种事故场景下不同人员伤害程度下的伤害阈值.该伤害阈值标准按对人员伤害程度的不同,分为高致死、致死出现、不可逆效应和可逆效应4种.给出的伤害阈值可应用于重大危险源或工业园区的安全评价、安全规划以及应急规划等工作.
給齣重大事故危害閾值的定義和主要類型.通過對國內外相關文獻的分析,確定齣火災、爆炸傷害準則,併對各種常見毒物緊急暴露閾值進行比較.在此基礎上,給齣各種事故場景下不同人員傷害程度下的傷害閾值.該傷害閾值標準按對人員傷害程度的不同,分為高緻死、緻死齣現、不可逆效應和可逆效應4種.給齣的傷害閾值可應用于重大危險源或工業園區的安全評價、安全規劃以及應急規劃等工作.

The definition and categories of hazardous thresholds are put forward. According to the related literature at home and abroad, the harm criteria for fire and explosion are determined. Then, the emergency exposure thresholds for common toxic substances are compared. Based on this, the harm threshold criteria for different harms under different accident scenario are given, which are classified into threshold of high lethality, threshold of starting lethality, threshold of irreversible effect, and threshold of reversible effect. These hazardous thresholds can be applied to the fields of safety assessment, land use planning and emergency planning for major hazard installations or industrial zones.
