A Resilience Index of Chemical Facilities
Safety should always come first in the chemical process industry (CPI). Traditional methods used to assess safety will obtain a result that only represents a system’s static property. Therefore, it is rather difficult for chemical companies to efficiently detect any deviation of safety toward edges of incidents or disasters while attempting to produce in the most efficient ways for maximizing profits under intense market competitions. In order to efficiently monitor the dynamic property of safety, the term “Resilience can be introduced into CPI. In this paper the Resilience Index (IR) of a chemical facility is proposed. IR is the ratio of hazard tolerance index (IHT) to potential hazard index (IPH). IHT represents the tolerance capacity of the chemical facility against hazards. IPH represents the potential adverse impact of the facility. Generally, IPH increases when production pressure or scale goes up. In order to keep the balance between production and safety, IHT has to be increased through, e.g., tightening up PSM when IPH goes up or stabilizing the production. As a dynamic and explicit indictor, IR can assist managers to make a proper decision to balance production pressures and safety, and therefore avoid or reduce the loss of accidents that could not be seen before what seems quite clear after with hindsight.
