Carbon Monoxide Poisoning: Tips for Staying Safe

Carbon monoxide, or CO, is a gas that you cannot see or smell but can cause sudden illness. CO is formed from nearly all combustion sources such as those produced by oil-, coal- or gas-burning furnaces and appliances, stoves, gas ranges, or by burning charcoal and wood. CO poisoning in Maine often occurs when people use gas-powered generators improperly, work on running engines in enclosed spaces, or run heating appliances that are not maintained or have blocked vents. When the power goes out, sometimes people use alternative sources of heating or cooking inside like portable generators and charcoal grills. This improper use of heating and cooking devices can cause CO to build up in a home and lead to CO poisoning.
 

Every year in Maine, CO poisoning is responsible for 1-3 deaths and approximately 100 emergency department visits. Sixty-eight percent of CO poisonings occur in the winter months between November and March. The Maine Tracking Network provides data from 2001-2016 on CO-related emergency department visits and hospitalizations, data on CO-related deaths from 2001-2015, and data on the prevalence of homes with a CO detector from 2004-2016. While the best way to prevent CO poisoning is to not let CO gas build up in your home, having CO detectors with a battery back-up near every sleeping area can save lives and is especially important when heating your home. These data show that as of 2016, an estimated 70% of households in Maine had a CO detector, nearly double the percentage in 2004.

 

The Maine Tracking Network helps public health officials to better target prevention efforts, design and implement protective policies, and understand the relationships between important environmental and health problems.

You can prevent carbon monoxide exposure.

  • Do have your heating system, water heater, and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
  • Do install a battery-operated CO detector near every sleeping area in your home and check them regularly. If the detector sounds, leave your home immediately and call 911.
  • Do seek prompt medical attention if you suspect CO poisoning and are feeling dizzy, lightheaded, or nauseous.
  • Do have a plan during power outages to run your generator outside at least 15 feet from any window, door, or vent. Make sure you have enough extension cord and a way to keep it protected from the weather.
  • Don’t use a generator, charcoal grill, camp stove, or other gasoline or charcoal-burning device inside your home, basement, garage, or near a window. Don’t heat your house with a gas oven.
  • Don’t run a car or truck inside a garage attached to your house, even if you leave the door open.
