Be on the lookout for any symptoms of CO poisoning. Call a qualified technician to inspect all equipment. Get immediate medical attention if anyone shows signs of CO poisoning. Safety checklist 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. If you need to warm up a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle, generator, or other fueled engine or motor indoors, even if garage doors are open.
