Prevent and Protect from CO Poisoning
Carbon monoxide Safety Tips
CO poisoning is preventable. Learn how to protect yourself, your loved ones, and your business. With colder temperatures and heating systems running for hours, the risk of carbon monoxide (CO) poisoning increases.
Dangers
Fumes can come from multiple sources such as furnaces, kerosene heaters, vehicles “warmed up” in garages, stoves, lanterns, and gas ranges, portable generators, even burning charcoal and wood. From these sources it can build up in enclosed or partially enclosed spaces. People and animals in these spaces can be poisoned and can die from breathing CO.
How to recognize symptoms
The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. People who are sleeping or who have been drinking alcohol can die from CO poisoning before ever having symptoms.

Prevention tips
Check or change the batteries in your CO detector every six months. If you don’t have a battery-powered or battery back-up CO detector, buy one soon.
- Have your heating system, water heater and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
- Keep vents and flues free of debris. Debris can block ventilation lines.
- Never leave the motor running in a vehicle parked in an enclosed or partially enclosed space, such as a garage.
- Never run a motor vehicle, generator, pressure washer, or any gasoline-powered engine less than 20 feet from an open window, door, or vent where exhaust can vent into an enclosed area.
- Never use a charcoal grill, hibachi, lantern, or portable camping stove inside a home, tent, or camper.
- Never run a generator, pressure washer, or any gasoline-powered engine inside a basement, garage, or other enclosed structure, even if the doors or windows are open.
- If you suspect CO poisoning, call 911 or a health care professional right away!
