Boating Accident/Carbon Monoxide Poisoning, Lake Winnipesaukee, Alton

On Saturday, July 21, 2018 at approximately 12:16 P.M. New Hampshire State Police – Marine Patrol received a call of an unresponsive 8-month old child on a boat on Lake Winnipesaukee in Alton. The adults on the boat were attempting to resuscitate the child. They were aboard a 35 foot Carver, operated by an adult male from Hampstead, New Hampshire.

When the vessel arrived at the Alton town docks, the 8-month old infant was responsive and crying. The child was transported to Lakes Region General Hospital, treated and released. The cause of the accident is believed to have been from carbon monoxide poisoning.

Shortly after arriving at the dock, an Alton Fire Department fire fighter was checking the boat for carbon monoxide levels. He opened the door to the forward V-birth on the vessel and found a 2-year old boy crying. The 2-year old was also transported to Lakes Region General Hospital, treated and released.

According to the Centers for Disease Control and Prevention, carbon monoxide (CO) is an invisible, odorless, colorless gas which can be fatal if too much is inhaled. Symptoms of CO poisoning include nausea, vomiting, headache, dizziness, loss of consciousness, weakness, chest pain, and confusion. On boats, CO can be caused by generators, gasoline engines, vessels traveling at slow speeds or improper angles causing CO build up in cabin areas, and wind bringing CO from the back of the boat to enclosed spaces.

New Hampshire State Police-Marine Patrol wants to remind boaters to make sure all safety equipment is working correctly before going out on the water. It is recommended that vessels with enclosed areas have a carbon monoxide detector, check it regularly, and replace it according to manufacturer recommendations.
