(WAFB) - A deadly explosion at the Williams-Olefins plant in Geismar on Thursday, June 13, 2013 left two people dead and injured 114 others.

According to reports, the fire was a result of a rupture in an off-line reboiler that was in standby mode, next to a boiler that was in operation.

The final report by the US Chemical Safety Board (CSB) states that "Process safety management program deficiencies at the Williams Geismar facility during the 12 years leading to the incident allowed a type of heat exchanger called a 'reboiler' to be unprotected from overpressure, and ultimately rupture, causing the explosion."
