The Deepwater Horizon oil split has been recognised as the one of the worst environmental disasters, if not the worst in the US History. On April 20, 2010, an offshore oil rig leased by British Petroleum's (BP) in the Gulf of Mexico exploded in a ball of flames on, killing 11 employees. While much of the nation was riveted by the attempts to cap the mile-deep well, the hidden tragedy was the cloud of tens of millions of barrels oil that was slowly creeping toward land. BP and others worked for over a year to clean up the beaches and wetlands affected by the spilled oil. The impact of this was felt by coastal wildlife and those who made their business working in the Gulf and along the shore.

In the case of the Deepwater Horizon, there were many things that ultimately lead to the failure of the rig and the release of the oil. Discuss the types of control Managers can take to prevent these disasters from occurring, provide examples to support your answer.
