BP has agreed to pay a record $50.6m (£32.5m) fine for failing to correct safety hazards at its Texas City plant. An explosion at the refinery in 2005 killed 15 people. The US Occupational Safety and Health Administration (OSHA) said the penalty "rightly reflects BP's disregard for workplace safety". BP said it had worked to enhance safety at the plant. OSHA is still working to collect another $30m from the company for other penalties that BP is contesting…BP also agreed to spend $500m on fixing safety problems at the refinery. "We respect OSHA's concerns and have addressed them in this agreement," said Iain Conn, BP's global head of refining.
