The U.S. Chemical Safety Board (CSB) has released a safety video of its investigation of the June 13, 2013 explosion and fire at the Williams Olefins Plant in Geismar, Louisiana, which killed two workers and injured an additional 167. The deadly explosion and fire occurred when a heat exchanger containing flammable liquid propane violently ruptured.

The 12-minute video entitled, “Blocked In,” includes a 3D animation of the explosion and fire as well as interviews with CSB investigator Lauren Grim and Chairperson Vanessa Allen Sutherland. The video is based on the CSB’s case study on the Williams incident and can be viewed on the CSB’s website and YouTube.
