BP management paints a grim picture of the poor state of the Texas refinery that exploded in 2005, according to the conclusions of a wide-ranging internal report conducted into the fatal blast.

Copies of BP's interview summaries, seen by the FT, quote various levels of management saying the Texas City refinery had a high acceptance of risk; employees worked weeks, if not months, of 12-hour days without a day off; maintenance was deferred; and training had been scaled back before the explosion, which killed 15 and injured 500 in and around the facility.
