LOS ANGELES, Sept 11 (Reuters) - The U.S. Coast Guard has issued a safety bulletin following the Labor Day fire on a California dive boat that killed 34 people, focusing on emergency escape routes, crew training and the charging of lithium-ion batteries.
The Coast Guard did not identify a cause of the early-morning blaze aboard the 75-foot (23-meter) Conception in the bulletin, and the incident remains under investigation by multiple local and federal law enforcement agencies.
But the document suggests that investigators may be looking into the possibility that the fire was ignited by passengers charging electronic devices in the below-decks sleeping quarters and could not escape once flames were raging in the cramped space.
"A Coast Guard Marine Board of Investigation (MBI) has been convened and will conduct a thorough and comprehensive marine casualty investigation to determine the causal factors that contributed to this tragic incident," the bulletin states.
It adds: "The Coast Guard and the maritime industry do not have to delay until the MBI has completed their investigation before taking immediate and positive action.
The Conception, owned by California-based Truth Aquatics, ignited at about 3:15 a.m. on Sept. 2, killing 33 passengers and a crew member as it sank off Santa Cruz Island.
ONE STILL MISSING
Five crew members who were above deck when the fire broke out survived by leaping overboard, telling investigators the fierce blaze made it impossible to rescue the passengers. The victims are believed to have died of smoke inhalation.
Divers have recovered the remains of 33 people and hope to retrieve the final body when the Conception is raised from the ocean floor as early as Thursday. Weather conditions have repeatedly delayed that operation.
The Coast Guard bulletin recommends that vessel owners "immediately" review crew training, make sure emergency escape routes are clearly identified and unobstructed and that required fire-fighting and live-saving equipment are on board.
The document also urges crews to "reduce potential fire hazards and consider limiting the unsupervised charging of lithium-ion batteries and extensive use of power strips and extension cords."
The Los Angeles Times has reported that investigators had identified possible safety lapses on the Conception, including the lack of a night watchman and failure to properly train the crew for emergencies.
Truth Aquatics has filed a petition in federal court in Los Angeles seeking to avoid liability by invoking a 19th-century law that has been used in such disasters as the sinking of the Titanic in 1912. (Reporting by Dan Whitcomb; Editing by Bill Tarrant and Sandra Maler)
