安全管理“事不过三”的数学原理

The Mathematical Principle of “Three and Out” in Security Management

事不过三是日常工作中用来警告人们不要同样的错误一犯再犯,做事情要把握好度,不能超越一定的次数,否则量变积累到一定程度就会引起质变。通过对海因里希法则的分析,发生三次无伤害事件,还可以认为处在相对安全状态,当第四次事件发生时,就被认为处在不安全状态,事故风险超过临界值,以此得出"事不过三"的结论。运用"事不过三"的数学原理,可以有效控制事故的发生,提高企业安全管理水平,达到预防和控制事故的目的。

＂Three and out＂is used to warn people not to repeat the same mistakes in daily work.Otherwise,quantitative change accumulates into a certain degree,it will result in the qualitative change.Through the analysis of Heinrich law,when harmless incidents have happened for three times,it can still be considered to be a relatively secure status.If the fourth accident happens,it will develop into an insecure status with accident risk exceeding critical values,which results in the conclusion of＂Three and Out＂.The application of this mathematical principles can effectively control the accident occurrence and improve the Enterprise＇s safety management proficiency,realizing the goal to prevent and control accidents.
