Where and How to Install Smoke and Carbon Monoxide Detectors.

Proper placement of smoke and carbon monoxide (CO) detectors is key for safety. Smoke detectors should be installed in every bedroom, outside sleeping areas, and on every level, mounted high on walls or ceilings, away from windows, vents, and fans. CO detectors should be on every level, especially near sleeping areas, placed 10–15 feet from fuel-burning appliances, and can be mounted at any height. Avoid bathrooms, kitchens, and garages to prevent false alarms. For combination units, follow smoke alarm placement guidelines.
