An investigative team from the U.S. Chemical Safety Board is deploying to the scene of a fire and explosion that occurred Thursday at the William Olefins Inc. plant in Geismar.

The investigative team will be led by CSB Western Regional Office Director Don Holmstrom and is expected to arrive in Louisiana over the weekend, according to a CSB news release.

The CSB is an independent federal agency charged with investigating industrial chemical accidents. CSB investigations look into all aspects of chemical accidents.
