What should I do if my FA6829S CO alarm sounds?

If the FA6829S alarm sounds:

1. Do not ignore it, even if you feel well
2. Move everyone, including pets, outside immediately
3. Leave doors open as you exit
4. Call 999 or the Gas Emergency number (0800 111 999) from outside
5. Do not re-enter the property until it has been checked and declared safe
6. Seek medical attention, as carbon monoxide poisoning can cause headache, dizziness, nausea, and confusion
