As colder temperatures arrive across Iowa, state officials are reminding residents to take precautions against carbon monoxide poisoning as homes begin using furnaces, fireplaces and other heating equipment.
Governor Kim Reynolds has proclaimed November 2026 as Carbon Monoxide Awareness Month, highlighting the dangers of carbon monoxide (CO), a colorless, odorless gas that can be deadly.
Carbon monoxide is produced when fuels such as natural gas, propane, gasoline and wood do not burn completely. Without proper detection, the gas can build up inside homes and other buildings, putting occupants at risk.
State Fire Marshal Dan Wood is encouraging Iowans to make sure their homes have working carbon monoxide and smoke alarms before the winter heating season gets underway.
The Iowa State Fire Marshal Division recommends several steps to help prevent carbon monoxide poisoning:
- Check alarms: Install carbon monoxide alarms on every level of the home and outside sleeping areas. Test alarms regularly and replace them according to manufacturer recommendations.
- Inspect heating systems: Have furnaces, fireplaces and other fuel-burning appliances inspected and serviced by qualified professionals.
- Operate generators outdoors: Never use generators inside a home or garage. Keep them at least 20 feet away from windows, doors and vents.
- Keep vehicles out of garages while running: Never idle a vehicle inside a garage, even if the garage door is open.
- Know the warning signs: Symptoms of carbon monoxide poisoning include headaches, dizziness, nausea, weakness and confusion.
If a carbon monoxide alarm sounds or poisoning is suspected, everyone should immediately move outside to fresh air and call 911. Residents should not reenter the building until emergency responders determine it is safe.
Carbon monoxide exposure can be especially dangerous for pregnant individuals, infants, older adults and people with certain underlying health conditions.
Officials stress that carbon monoxide poisoning is preventable. Checking alarms and making sure heating equipment is operating properly can help protect Iowa families throughout the colder months.
