Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that provides no warning signs, even when enough is present to cause serious health effects—or even death. Often called the “silent killer,” carbon monoxide is created when fuels are burned without sufficient ventilation. When these fumes build up indoors, they can quickly become harmful; sometimes without anyone realizing it.

Carbon monoxide can come from common household appliances like furnaces, water heaters, fireplaces, generators, and space heaters. Unvented, fuel-burning space heaters can be especially risky because they release gases directly into the room. It’s important to never use a gas stove or oven to heat your home. This can cause dangerous levels of carbon monoxide to build up, and lead to serious health problems such as brain damage, heart problems, and even death.

The good news is that carbon monoxide poisoning is preventable. Make sure fuel-burning appliances are properly installed and well maintained. Never run cars, grills, or generators inside your garage or home and make sure to keep generators at least 20 feet away from the doors and windows of your home.

To prevent carbon monoxide poisoning, New York State law requires carbon monoxide alarms to be installed in all single- and multiple family homes. Alarms should be installed near sleeping areas and on each level of the home. Ensure carbon monoxide alarms are operational by testing battery-operated alarms monthly and using the “Time Change, Battery Change” saying to ensure batteries are checked or replaced when the time changes— it’s a simple step that can save lives.

If your carbon monoxide alarm goes off, or if anyone feels symptoms like headache, dizziness, nausea, or confusion, go outside for fresh air and call 911 right away. Trust your alarm and take action--your safety comes first.
