The issue of the standard for evaluating F&EI's hazard level classification and the compensation coefficient C for safety measures using the Daohua method
Thread Content
What are the criteria for classifying F&EI hazard levels in Daohua method evaluation? If MF=10, F3=16, if F3 is taken as 8.0 as required, then the fire and explosion index F&EI=MF×F3=80, the hazard level is relatively light. If calculated directly as 16, it is 160. If it exceeds 159, the hazard level is very high. Does this calculation affect the hazard level classification? In addition, the safety measure compensation coefficient C is used when calculating the actual maximum possible property loss (actual MPPD) according to regulations. However, when I looked at the materials recently, I found that a company substituted C into the F&EI calculation (F&EI=MF×F3×C). The reason is that there are safety measures that can reduce the risk level. Is this wrong?
Dow chemical evaluation methods clearly explained: If F3>8, take 8.0 ； As for the safety measure compensation coefficient C, C can be substituted into the calculation of F&EI (compensated F&EI=MF×F3×C), thereby calculating the compensated system fire and explosion hazard index and determining the risk level of the system. The author can take a look at the relevant knowledge of this evaluation method.
