An expert testified that when something goes wrong with a well, the fail-safe device's shears are supposed to clamp down, cut and seal the drill pipe, preventing the oil from escaping.

A worker on the rig which exploded in the Gulf of Mexico claimed Monday he found a fault in a key piece of safety equipment weeks before the disaster, a British television report said.Tyrone Benton told the BBC the fault on the Deepwater Horizon rig was not fixed and instead the device, known as a blowout preventer, was shut down and a second one used.He told the BBC that repairing it would have meant stopping drilling work at a time when it was costing 500,000 dollars a day to operate the rig, the source of the massive oil spill.
