OAKLAND -- A worker suffered fatal injuries Wednesday morning at the Port of Oakland after he was crushed while inspecting a crane, authorities said.

The man's name was not released.

Police said the man was with another worker inspecting a crane when he was crushed by a moving portion of the crane. The other man was not injured.

The apparent industrial accident happened around 9:30 a.m. at Berth 37, part of the Ben E. Nutter Terminal, which is operated by Evergreen Marine Corp. of Taiwan. The worker was taken to Summitt Medical Center where he later died.

The worker was crushed in the chest and suffered a head injury, according to Peter Melton of Cal OSHA.

The worker is a crane mechanic, affiliated with the International Association of Machinist and Aerospace Workers, according to port spokeswoman Marilyn Sandifur.

According to Robert Bernardo, the Port of Oakland's Manager of Media & Public Relations, the Ben E. Nutter Terminal was shut down and workers sent home while local agencies and Cal OSHA conducted their investigation. The port, which handled about $41 billion worth of cargo in 2011, is the fifth-busiest seaport in the United States.
