Carbon monoxide (CO) has been called the “silent and invisible killer” because it doesn’t have a smell, color, or taste. It’s one of the most prevalent causes of death due to poisoning in America. Any time you burn something—like gasoline, natural gas, wood, oil, propane, or charcoal—carbon monoxide is released into the air.
In outdoor spaces, this usually isn’t a health hazard because there is enough area for the CO to dissipate, so particles never amount to a toxic level. The danger comes when carbon monoxide is released in a contained area like your home, RV, or garage.
Anything that burns will create carbon monoxide. It’s not just your stove, fireplace, or grill either. Here are some of the things that can create carbon monoxide when turned on:
- Appliances
- Gas grills
- Gas stoves
- Gas or oil-burning furnaces
- Fuel-burning water heaters
- Pressure washers
- Generators
- Non-electric cars, trucks, and boats
- Chain saws
- Non-electric space heaters
- Tools
- Snowblowers
- Lawnmowers

Lighting a fire in your fireplace is okay if it’s properly ventilated. However, keep the following in mind or you could cause a dangerous level of carbon monoxide to build in your home:
