The following checklist provides a general practice information:

• Carbon Monoxide (CO) alarms are not substitutes for smoke alarms. Smoke alarms react to fire by-products, before CO alarms would sound. Smoke alarms give earlier warning of a fire, providing more time to escape.
• To guard against smoke and fire, be sure that your home has working smoke alarms on every level and in or near all sleeping areas.
• Know the difference between the sound of the smoke alarms and the sound of the CO alarms.
• Have a home escape plan for any home emergency and practice the plan with all members of the household regularly, at least twice a year.
