A dock worker was killed today in an accident at a Port of Los Angeles container terminal, port officials said.

The incident, which also resulted in serious injury to another worker, took place at 7:25 a.m at Fenix Marine Services container terminal at Pier 300.

The accident involved a top loader container handler, according to initial reports.

The injured worker was taken to Harbor UCLA Medical Center.

The names of the two workers, both members of the International Longshore and Warehouse Union, are not yet available, port officials said.

“My heart goes out to the families of the victims of this tragic accident and to all the brothers and sisters of the International Longshore and Warehouse Union,” port executive director Gene Seroka said.

“It’s particularly tragic that this accident occurred on the day of the ILWU’s annual ‘First Blood’ event, which honors those who have lost their lives working on the waterfront.”

Port police, California's Division of Occupational Safety and Health and the US Coast Guard have begun an investigation into the accident.

The Fenix Marine Services container terminal is currently closed.

"Today is a tragic reminder of the danger that thousands of workers face every day working on our docks," Los Angeles city councilman Joe Buscaino said.

"My office will continue to work with the agencies investigating this accident.”
