U.S. Steel’s Deadly Valve Flushing Failure | Lubbock News

A deadly 2025 explosion at U.S. Steel’s Clairton Coke Works—killing two and injuring eleven—was caused by a ruptured gas valve during routine water-flushing maintenance, a task performed without formal safety procedures. The valve, over 70 years old and made of brittle cast iron, failed under pressure, releasing combustible gas. Investigators blame years of informal, unsafe practices and poor site planning, including buildings directly above hazardous piping. The Chemical Safety Board now demands written protocols to prevent future disasters, while OSHA had previously fined the company $118,000 for outdated safety procedures—highlighting a pattern of negligence after a similar 2010 explosion injured 20 workers.
