Hazardous Chemical
Storage Design
Hazardous chemical storage has been the source of three of the deadliest industrial events of the last twenty years: West Fertilizer 2013 (15 fatalities, ammonium nitrate detonation following fire), Tianjin Port 2015 (165 fatalities, mixed-chemical warehouse cascade), and Beirut Port 2020 (218 fatalities, 2,750 tonnes of ammonium nitrate stored adjacent to fireworks for 6 years). Modern storage design now combines NFPA 30 (flammable / combustible liquids), NFPA 400 (hazardous materials code), OISD-STD-118 (India), FM Global Data Sheets 7-29 / 7-32 / 7-95, COMAH / Seveso III major-accident inventory thresholds, segregation matrices per CGA and HSE guidance, and increasingly the EPA RMP and OSHA Process Safety inventory-coverage logic. The discipline integrates inherently-safer-design inventory minimisation, multi-layer segregation (cabinet → cell → room → building → site), engineered secondary containment (bunds typically 110% of largest tank or 25% of total inventory whichever greater), fire-resistance-rated walls and floors, controlled-ventilation regimes for toxic / flammable storage, automatic detection and suppression, and chemical-incompatibility-aware emergency response. The 2020s have added new pressures: lithium-ion battery storage (LIB) representing a new fire-and-thermal-runaway class, hydrogen and ammonia at industrial scale, and post-Beirut tighter regulatory inventory disclosure regimes globally.
