"Federal investigators are blaming company safety culture, flawed emergency response and inadequate federal regulations for a 2012 fire at a Chevron Corp. refinery in California.

The conclusions were the result of an extensive investigation of the incident at the Richmond, Calif., refinery from the Chemical Safety Board (CSB). The board released its draft report Thursday and will meet next week to make it final.

The incident also created a vapor cloud that engulfed 19 workers, and 15,000 local residents sought medical treatment after the fire, the CSB said."
