The explosion of a BP oil rig which has resulted in the biggest oil spill in U.S. history over the last two months could have been prevented, according to a company employee who was aboard the rig.

Tyrone Benton, a rig worker aboard BP’s Deepwater Horizon rig, told several news outlets that he saw a leak in the rig’s safety equipment weeks before the blast and instead of it being fixed, the device was shut down, forcing the rig to use a backup device which eventually failed.

“We…saw that there was an angular fitting that had a leak on it,” Benton told CNN. “What was connected to the angular fitting wasn’t , but there was an angular fitting that did have a leak.”

“It wasn’t taken care of,” he said. “In order to take care of it, you have to pull the whole , which will shut down production. From like I said, from my understanding, they just shut down one pod and work off the other.”

Benton said he notified Transocean, the subcontractor in charge of the rig, and BP of the issue. That subcontractor may share some of the blame for the disaster, BP said

“Other parties besides BP may be responsible for costs and liabilities arising from the oil spill, and we expect those parties to live up to their obligations,” BP CEO Tony Hayward said, according to The Huffington Post.

Benton’s statements are just the latest in a series of media blunders for BP. Hayward recently called the people of the Gulf Coast “small people”; he took a high-profile yachting vacation last weekend in the midst of the crisis, which drew great criticism; and at a recent hearing at the U.S. Capitol, Hayward claimed to not be a part of much of BP’s decision-making process.

“I wasn’t part of the decision-making process,” Hayward said during the hearing. “I’m not a cement engineer, I’m afraid. I am not a drilling engineer…I’m not an oceanographic scientist.”

His claimed ignorance of the company’s practices frustrated congressmen at the hearing.

“You’re kicking the can down the road and acting as if you had nothing to do with this company and nothing to do with the decisions,” said Rep. Henry Waxman, D-Calif., chairman of the House Energy and Commerce Committee. ” I find that irresponsible.”
