Emergency crews on Wednesday are trying to extinguish the fire that erupted after an explosion on a natural gas rig in the Gulf of Mexico that forced the evacuation of 44 workers, the U.S. Coast Guard reported.

Coast Guard Petty Officer Carlos Vega said that the blast produced a huge fireball on the rig, located 88 kilometers (55 miles) off the southern coast of Louisiana.

CBS reported that participating in the firefighting efforts are personnel from Wild Well Control Inc., who are determining the best way to bring the blaze under control.

The Coast Guard and the Federal Aviation Administration are keeping sea- and air-traffic away from the rig.

The 44 evacuated workers were placed on board a floating drilling platform owned by Hercules Offshore, a contractor for Walter Oil and Gas. EFE
