What changed

The Connecticut Department of Public Health (DPH) has issued a public health advisory warning residents about the dangers of carbon monoxide (CO) poisoning and heart-related emergencies due to snow shoveling during an anticipated major winter storm. The advisory emphasizes the risks associated with improper use of generators and heating equipment, as well as the physical strain of clearing snow in cold temperatures. In 2023, Connecticut saw 126 emergency department visits and 17 hospitalizations from unintentional CO exposure, with an average of seven deaths annually linked to CO poisoning.

Residents are urged to take preventative measures, including never using fuel-burning equipment indoors, placing portable generators at least 20 feet from homes, installing CO alarms, and ensuring heating systems are inspected. For snow shoveling, individuals are advised to pace themselves, take breaks, push snow rather than lift, and stop immediately if experiencing chest pain or shortness of breath. The DPH also provides contact information for the Connecticut Poison Control Center and relevant health resources. While this is a public health advisory and not a regulatory rule, adherence to these safety recommendations is crucial to prevent serious injury or death during winter weather events.

What to do next

Ensure carbon monoxide alarms are installed on every level of the home and near sleeping areas.
Verify that dryer vents, exhaust pipes, and vehicle tailpipes are clear of snow.
Advise individuals engaging in snow shoveling to pace themselves, take breaks, and stop if experiencing cardiac symptoms.

Press Release Homepage Ahead of major winter storm, DPH warns of carbon monoxide and snow shoveling risks Unintentional carbon monoxide exposure hospitalized 17 Connecticut residents and sent more than 100 to emergency departments in 2023 1/23/2026 HARTFORD, Conn. — With a major winter storm expected to impact Connecticut from Sunday into Monday, the Connecticut Department of Public Health is warning residents about the dangers of carbon monoxide poisoning and heart risks linked to snow shoveling and heavy exertion. “Winter storms increase risks both inside and outside the home,” said DPH Commissioner Manisha Juthani, MD . “Using generators or heating equipment the wrong way can cause carbon monoxide poisoning, and heavy snow shoveling can trigger heart emergencies. Taking simple precautions can save lives during this storm.” Carbon monoxide, or CO, is a colorless, odorless gas that can be deadly. It is produced when fuels such as gasoline, natural gas, propane, wood, charcoal, or kerosene do not burn completely. Power outages and increased use of heating equipment during storms raise the risk of exposure. Carbon Monoxide Safety Tips DPH urges residents to take the following steps to prevent carbon monoxide poisoning: Never use generators, grills, or fuel-powered equipment inside homes, garages, basements, or near open windows or doors. Place portable generators at least 20 feet from the home, with exhaust pointing away from buildings. Install carbon monoxide alarms on every level of the home and near sleeping areas. Keep dryer vents, exhaust pipes, and vehicle tailpipes clear of snow. Have heating systems and fuel-burning appliances inspected yearly by qualified professionals. Carbon monoxide alarms are the only way to detect the gas. Alarms should be maintained according to manufacturer instructions and replaced every 7 to 10 years. In 2023, Connecticut recorded 126 emergency department visits and 17 hospitalizations due to unintentional carbon monoxide exposure. In a typical year, about seven deaths in the state are linked to carbon monoxide poisoning. Symptoms of carbon monoxide poisoning include headache, dizziness, fatigue, confusion, nausea, and loss of consciousness. If multiple people in a home feel sick at the same time and feel better outdoors, carbon monoxide may be present. Anyone with symptoms should leave the home immediately, call 911, and contact the Connecticut Poison Control Center at 1-800-222-1222 . Snow Shoveling and Heart Safety DPH also warns that snow shoveling can trigger heart attacks, especially in cold temperatures. Residents should pace themselves, take breaks, push snow instead of lifting when possible, and stop immediately if they experience chest pain, shortness of breath, dizziness, or extreme fatigue.
