Carbon Monoxide Safety

• In 2023, the National Fire Incident Reporting System data included 82,245 CO incidents which required a local fire department response. This does not include the 79,051 CO alarm malfunctions and the 79,286 CO alarm activations where no CO was found present.
• A 2023 study by the U.S. Centers for Disease Control found unintentional non–fire-related CO poisoning between 2005 and 2018 to be annually responsible for approximately 101,847 emergency department (ED) visits (48.3 visits per 1 million), 14,365 hospitalizations (4.1 cases per 1 million), and at least 430 deaths.

• CO alarms should be installed in a central location outside each sleeping area and on every level of the home and in other locations where required by applicable laws, codes or standards. For the best protection, interconnect all CO alarms throughout the home. When one sounds, they all sound.
• Follow the manufacturer’s instructions for placement and mounting height.
• Choose a CO alarm that has the label of a recognized testing laboratory.
• Call your local fire department’s non-emergency number to find out what number to call if the CO alarm sounds.
• Test CO alarms at least once a month; replace them according to the manufacturer’s instructions.
• If the audible trouble signal sounds, check for low batteries. If the battery is low, replace it. If it still sounds, call the fire department.
• If the CO alarm sounds, immediately move to a fresh air location outdoors or by an open window or door. Make sure everyone inside the home is accounted for. Call for help from a fresh air location and stay there until emergency personnel.
• If you need to warm a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle or other fueled engine or motor indoors, even if garage doors are open. Make sure the exhaust pipe of a running vehicle is not covered with snow.
• During and after a snowstorm, make sure vents for the dryer, furnace, stove, and fireplace are clear of snow build-up.
• A generator should be used in a well-ventilated location outdoors away from windows, doors and vent openings.
• Gas or charcoal grills can produce CO — only use outside.

CO enters the body through breathing. CO poisoning can be confused with flu symptoms, food poisoning and other illnesses. Some symptoms include shortness of breath, nausea, dizziness, light headedness or headaches. High levels of CO can be fatal, causing death within minutes.

The dangers of CO exposure depend on several variables, including the victim's health and activity level. Infants, pregnant women, and people with physical conditions that limit their body's ability to use oxygen (i.e. emphysema, asthma, heart disease) can be more severely affected by lower concentrations of CO than healthy adults would be.

A person can be poisoned by a small amount of CO over a longer period of time or by a large amount of CO over a shorter amount of time.
