Carbon monoxide fumes from snow-blocked heater vent send Bar Harbor family to hospital

BAR HARBOR, Maine — A woman and her three children were treated for carbon monoxide poisoning Tuesday morning at a local hospital after fumes built up inside their apartment because a heater vent was blocked by snow.

The woman and her children called 911 a few minutes before 8 a.m. after they started feeling sick, according to Bar Harbor Fire Chief Matt Bartlett, who declined to identify the family.

The fire chief said a deep snowdrift outside the apartment on lower Rodick Street blocked a vent to a propane heater inside the dwelling, causing the invisible and odorless gas to build up inside.

Bartlett, whose department also provides ambulance services to the town, said the first thing emergency responders did was turn off the exterior propane tanks and take carbon monoxide readings inside the apartment. The family did not have a carbon monoxide detector, he said.

“We got some pretty high readings” the fire chief said.

After determining that the gas concentrations were making the family ill, they were taken to MDI Hospital in Bar Harbor to be checked out, according to Bartlett. He said they are expected to be fine.

Responders cleared away the snow from the exterior vent, Bartlett said, and called the propane provider to come check on the heater and make sure it was functioning properly.

Public safety officials have cautioned that the recent low temperatures and heavy snowfall throughout the state and region could create problems from heaters being improperly used or vented.

Symptoms of carbon monoxide poisoning include headaches, nausea and fatigue. Exposure to high levels of carbon monoxide can be fatal after just a few minutes.

Last week, a Yarmouth man was rushed to the hospital after he was found suffering from the effects of carbon monoxide fumes in his home, which also had snow-covered heating vents and no carbon monoxide detector. Last year, a Whitefield man died after he and his wife were overcome by carbon monoxide fumes from a generator running in a garage attached to their home.

The deadly fumes also can build up in motor vehicles that have the engines running but the exhaust pipes are blocked by snow or other obstructions, as in a 2013 incident in which a boy died in Boston.

Bartlett said people need to make sure their heat sources are properly vented and that they are not using portable generators or heaters in any part of their home, including garages and basements. It also is important to have properly operating carbon monoxide detectors in every house, he said.

“You really need to make sure your exhaust [vents] are open and free,” the fire chief said.
