Development of a resilience safety culture model for the hazardous materials processing industry

Many previous cases have demonstrated that hazardous materials processing industry (HMPI) accidents always result in huge losses and HMPI companies which suffer accidents are difficult to quickly restore. This has demanded an effective way to solve the two problems. Resilience safety culture (RSC) combines conventional safety culture and resilience engineering. It aims at giving an organization the abilities of continually operating or timely recovering during or after a major unexpected event. RSC fits the safety demands of the HMPI well. The present study develops a RSC model for the HMPI. Firstly, through literature review, 12 model elements with 16 hypothesized relationships are developed. These hypothesis are then tested by 618 samples with structural equation modelling. Finally, an HMPI RSC model with 12 elements and 12 relationships is established. Model validity is verified by a comparison study on the proposed model and two existing models with the fuzzy analytic hierarchy process.

诸多既往案例均已证实，危险物料加工行业（Hazardous Materials Processing Industry，简称HMPI）事故往往会造成巨额损失，且涉事企业难以快速恢复运营。这一现状亟需有效方案破解上述两大难题。弹性安全文化（Resilience Safety Culture，简称RSC）融合了传统安全文化与弹性工程，其核心目标是使组织在重大突发意外事件发生期间或发生后，仍可维持持续运转或及时完成恢复。弹性安全文化恰好契合危险物料加工行业的安全需求。本研究针对危险物料加工行业构建了弹性安全文化模型：首先，通过文献综述梳理出12项模型要素与16条待验证假设关系；随后基于618份样本数据，运用结构方程模型（Structural Equation Modelling）对上述假设进行检验；最终确立了包含12项要素与12条关系的危险物料加工行业弹性安全文化模型。最后，通过将所提模型与两类现有模型开展对比研究，并结合模糊层次分析法（Fuzzy Analytic Hierarchy Process）验证了该模型的有效性。
