Risk includes three elements: risk source, risk factor, and risk event, among which the risk event is the core of the three elements. Risk events and accidents are two concepts of the same coin; a risk event is a potential accident, and an accident is the final transformation of a risk event. Therefore, accident analysis is the starting point of risk research and the basis for analyzing the formation mechanism, influencing factors, and consequences of risk.

摘要

Risk includes three elements: risk source, risk factor, and risk event, among which the risk event is the core of the three elements. Risk events and accidents are two concepts of the same coin; a risk event is a potential accident, and an accident is the final transformation of a risk event. Therefore, accident analysis is the starting point of risk research and the basis for analyzing the formation mechanism, influencing factors, and consequences of risk.
