On a clear morning in 1947, a small fire broke out in the cargo hold of a ship docked in Texas City. Onlookers gathered to watch the colorful smoke. They didn't know the ship was packed with over 2,000 tons of ammonium nitrate—the same chemical compound used in massive bombs. The resulting explosion vaporized the ship, triggered a localized tidal wave, and killed nearly 600 people. The Texas City Disaster remains the deadliest industrial accident in United States history. Yet, it was the tragic culmination of willful corporate negligence, a complete lack of chemical regulation, and post-war logistical chaos. The devastating chain reaction leveled entire chemical plants and shattered the illusion that heavy industry could police itself. This book chronicles the terrifying timeline of the blast and the heroic, doomed efforts of the local fire department. It dissects the subsequent legal battles, marking a turning point that forced the government to completely overhaul hazardous materials shipping and industrial zoning laws. Explore the explosion that changed American industry. Understand how the catastrophic mishandling of fertilizer led to thousands of casualties and birthed the modern safety regulations that protect workers today.
