Lawsuits, multiple investigations on the state and federal level, plus the USW Union and BP's own investigation created thousands of pages of documents related to the 2005 explosion at the Texas City refinery that killed 15 people and injured more than 170.
Below is a selection of some of the most critical of those documents related to the tragedy.
|In November 2014, about four months before the fatal explosions, then BP Texas City refinery manager Don Parus traveled to BP corporate headquarters in London and presented a slide show entitled "Texas City is not a safe place to work."
