Closed Valve Likely Caused Fatal Houston Blast, Feds Say

A closed valve that allowed pressure to build probably caused the explosion that killed an employee and injured six others at a southeast Houston chemical plant, the U.S. Chemical Safety Board reported.

The board is continuing its investigation into the June 11 blast and likely will focus on the company's practices for managing, inspecting, and maintaining relief systems; training operators and accounting for workers during emergencies, said CSB Chairman John Bresland.
