HOUSTON (AP) -- Federal officials are investigating the causes of a June explosion that killed one employee and injured several others at a Houston synthetic rubber plant.
The U.S. Chemical Safety Board announced Wednesday that it will look at the rupture of a heat exchanger at the Goodyear plant. Investigators will likely focus on the company's pressure relief systems and how it trains operators and accounts for workers during emergencies.
CSB officials have finished conducting interviews at the plant and gathering other evidence.
The body of production supervisor Gloria McInnis was found about seven hours after the morning blast. The plant was evacuated for several hours after the explosion on June 11.
