"The Coast Guard is now putting out a "safety alert" due to the fire on the diving vessel Conception, in California. Among other things:
Boat operators also should "reduce potential fire hazards and consider limiting the unsupervised charging of lithium-ion batteries and extensive use of power strips and extension cords," the bulletin said.
The batteries, found in millions of electronic devices around the world, charge and discharge by moving lithium particles between a negative and positive electrode. The particles are suspended in pressurized cells inside the batteries – filled with volatile, flammable chemicals. Incidents of rechargeable battery fires, however, are extremely rare.
"The intensity of the fire surprised people," Peter Goelz, former managing director of the National Transportation Safety Board, told USA TODAY. "If it was being fed by lithium batteries, that might explain it.""
