Get to Know CO

Carbon monoxide is a deadly, odorless gas that’s very difficult to detect without a CO alarm. It's produced by fuel-burning appliances, like gas stoves and fireplaces.

Place Your Alarms Where They Matter

Make sure you have a CO alarm on every level of your home and outside of each sleeping area. Plus, add an explosive gas alarm to areas like kitchens and basements.

A graphic illustrating where a carbon monoxide alarm should be installed, and where a explosive gas alarm should be installed. Carbon monoxide alarms should be installed in the hallways outside of bedrooms, in the living room and in the basement. The explosive gas alarm should be installed in the kitchen and in the basement or over 6 ft away from a natural gas appliance.

Pack Peace of Mind

Not all hotels and rentals are required to have CO detection. For safer travels, take a CO alarm on your next trip.1
