(AP) Officials from the south Louisiana chemical plant where an explosion and fire killed one worker and injured dozens say a crew is securing equipment and making sure the plant is shut down properly.
The president and CEO of plant owner Williams Companies Inc., held a news conference in Gonzales on Friday. Alan Armstrong says the extent of the plant's damage is unknown and it is unclear when operations will resume. He also says the cause isn't yet known.
Company officials say they are cooperating with officials from the U.S. Labor Department's Occupational Safety and Health Administration, which is investigating the explosion.
Witnesses described a chaotic scene of towering flames and workers scrambling over gates to escape the plant Thursday after the explosion.
