Washington, June 17 (RHC)-- Federal regulators probing the worst offshore oil spill in U.S. history are warning a failed safety device could pose a risk of future catastrophic spills.
A report by the Chemical Safety Board cites improper testing and other key issues surrounding the blowout preventer, an emergency device that should have staunched the flow of oil during the 2010 BP oil spill.
Devices with the same design are currently in use on at least 30 other drill rigs around the world.
