Euro Power: Far curves stable after US election result, spot prices mixed

Federal investigators looking into a deadly explosion at a fertilizer plant in West, Texas are blaming state and federal regulators for not properly overseeing how chemicals were stored.

A U.S. Chemical Safety Board report released Tuesday concluded that there are three main scenarios for the explosion, which killed 150 and injured more than 160 in 2013.

The report focused heavily on how the plant was storing its ammonium nitrate, CBS Dallas reported Tuesday. The study also blamed the heat, pressure and debris from a fire for helping cause the explosion.

The study also faulted the facility's insurance company with failing to conduct a proper safety inspection of the plant. There were “shortcomings” in the emergency response to the incident, the study said, including for the volunteer firefighters who responded to the fire.
