Major industrial disasters are not accidents. They are the logical outcome of systems operating exactly as designed.From Seveso to Fukushima, from Bhopal to AZF, from Piper Alpha to Deepwater Horizon, this book examines the most significant industrial catastrophes of modern history: chemical explosions, nuclear accidents, refinery disasters, factory collapses, mining accidents, oil spills, and large-scale industrial pollution.In every case, the same pattern emerges.The risks were known.Warnings existed.Audit reports, safety inspections, and technical analyses were available.Yet shutdowns were postponed. Compliance was delayed. Protective measures were compromised. Production continuity, economic pressure, political constraints, and organizational inertia consistently prevailed over safety.This book does not seek individual scapegoats or simplistic explanations. Instead, it dismantles the recurring mechanisms of industrial risk management failure: normalization of deviance, diffusion of responsibility, implicit economic trade-offs, performance-driven cultures, and the illusion of control created by procedures and paperwork. It shows how rational, structured, and sometimes exemplary organizations systematically produce major accidents.Each chapter is based on documented facts, technical data explained in accessible terms, and a rigorous analysis of the managerial and organizational decisions that led to disaster. A dedicated section explores post-accident consequences: regulatory changes, risk displacement, and the hidden continuities behind announced reforms.20 Industrial Disasters is written for professionals in industry, safety management, risk management, engineering, energy, chemicals, and nuclear sectors-but also for anyone seeking to understand why, in modern industrial societies, prevention fails precisely where everything appears to be under control.Human life becomes a priority only after the accident.When it is already too late.
