KEENE, N.H. (MyKeeneNow) As the cooler months approach, New Hampshire officials are warning residents about the risks of carbon monoxide (CO) poisoning and home heating fires.

With temperatures dropping, many households are firing up their heating systems, a period that fire departments say often leads to an increase in emergency calls.

State Fire Marshal Sean P. Toomey emphasized the importance of fire safety, noting in a news release that heating equipment has been linked to nearly 2,000 fires in the state over the past five years. Toomey advises homeowners to keep anything flammable at least three feet away from space heaters, fireplaces, and wood stoves.

In addition to the fire risk, carbon monoxide poses a serious threat. CO is a colorless, odorless gas produced by devices that burn fuels like oil, wood, gas, and kerosene—common heating sources in New Hampshire homes, the release said. The gas can quickly replace oxygen in the bloodstream, potentially leading to fatal poisoning if undetected. Toomey stressed the importance of working CO alarms, as the symptoms of poisoning, such as dizziness, headache, and nausea, can often be subtle.

“Do not ignore these symptoms, especially if more than one person is affected,” Toomey warned. “If you suspect carbon monoxide poisoning, get outside to fresh air immediately and call 911.”

Essential Safety Steps for the Heating Season

Fire and emergency officials are urging New Hampshire residents to take preventive measures as the heating season begins. Key tips include:

  • Install and Maintain Alarms: Smoke alarms should be placed inside and outside of bedrooms, with at least one on each level of the home. CO alarms should be located centrally outside sleeping areas and on every floor. Both types of alarms need to be tested monthly.
  • Annual Inspections: Heating systems and chimneys should be inspected and cleaned by professionals annually to ensure safety.
  • Safe Heater Use: Flammable objects should be kept at least three feet from heaters. Residents are reminded never to use an oven for heating purposes.
  • Follow Instructions: Always use the proper fuel for heating devices and carefully follow the manufacturer’s guidelines.

According to national data, almost half of home heating fires occur during winter. Additionally, only 14% of homes are believed to have properly functioning CO alarms, according to the National Carbon Monoxide Awareness Association.

Sources of Carbon Monoxide

Common sources of CO in and around the home include heating systems, stoves, fireplaces, and vehicles idling in attached garages. Gas-powered tools and generators, often used outdoors, can also pose a risk if they are operated too close to buildings.

To reduce the risk of carbon monoxide exposure, residents should:

  • Properly maintain gas appliances.
  • Never use gasoline-powered engines or generators in enclosed spaces.
  • Avoid idling vehicles in garages.
  • Ensure tight seals on wood stove doors.
