Exhaust Fumes Overcome 2 in Boat Parade

Boaters in the Newport Harbor Christmas Boat Parade should beware of carbon monoxide fumes on the slow-moving craft, officials warned Wednesday after two passengers were overcome.

Two women, who were not identified, were rendered unconscious while riding in the rear of a sport-fishing boat during the parade Monday, said Newport Beach Fire Marshal Dennis Lockard.

Both women, age 55, were treated for carbon monoxide poisoning at Hoag Memorial Hospital Presbyterian in Newport Beach after tests found the level in their blood more than 100 times than normal, Lockard said.

Lockard said engine exhaust normally left behind by moving boats can gather on board when boats are traveling slowly or idling. He said there were three cases of carbon-monoxide poisoning during last year’s parades.

“The exhaust of most of the larger marine vessels goes right out through the rear transom,” he said.

Lockard warned boaters to ride in well-ventilated areas and recognize the early signs of carbon-monoxide poisoning: headaches, nausea, faintness and breathing difficulties.

The 86th annual parade runs nightly through Friday.
