BP admitted last night that it had fallen short of safety standards after the death of another worker at its Texas City refinery this week. William Joe Garcia, an operations supervisor with 32 years’ experience, died on Monday in the third fatality at the refinery since a massive blast nearly three years ago claimed 15 lives... A spokesman for BP...said that the company was investigating the accident. He said: “Our efforts have been ongoing and we have succeeded in driving safety levels. Our overall safety performance in 2007 will be the best ever.”... However, critics of BP..[asserted] that the latest death was symptomatic of a lax approach to safety... Brent Coon, the lawyer representing the victims of the 2005 disaster, said...the company’s safety record, of one fatality a year, was the same now as it was before 2005.
