This multidisciplinary study assesses risks in a high-pressure vessel storing flammable n-heptane. Using failure diagrams, corrosion modeling, and hazard zoning, it provides a holistic safety evaluation. Results show structural integrity is highly pressure-sensitive, with 60 MPa causing near-critical stress versus safe operation at 30 MPa. Corrosion modeling predicted a 0.92 mm wall loss over 20 years, remaining within safety limits. Vapor dispersion ranged from 2.99–13.86 m, informing electrical and ventilation designs. The research underscores integrating engineering disciplines for predictive safety strategies and promotes inherent safety over add-on measures.
