The hazard that prevails in the chemical storage area of a process industry is exceptionally high in contrast to other different areas. In the present scenario, upcoming process industries handle different hazardous chemicals for processing, due to which the chemical storage area draws more attention with regard to safety. It is very hard to repair the damages brought about unintentionally in a chemical warehouse. Resilience-based Integrated Process System Hazard Analysis (RIPSHA) approach is a recently developed methodology to examine the varied nature of an accident. In this study, storage areas of chemicals, namely sulfuric acid, phosphoric acid, hydrochloric acid, caustic (sodium hydroxide), ammonia in an edible oil refinery in South India were considered for resilient analysis. The results of the study were made in RIPSHA worksheet and represented graphically. The existing risk has been adequately investigated in both plant system layers and managerial system layers, and it has been found that the safety precautions and structural design of the chemical storage area needed development.
