Anyone in the household who is elderly, has anemia, heart disease,
respiratory problems, emphysema, or chronic bronchitis, is at a higher
risk of CO poisoning and health problems from exposure to CO. If any-
one in the household is at high risk for CO poisoning, we urge you to
take extra precaution to prevent possible poisoning. You should consid-
er a more sensitive alarm for your home safety. If the unit alarms or if
CO readings are shown on the digital display, remove the at-risk person
from the premises. Ventilate the area.
The high-risk person(s) should not re-enter the residence until the
source of the CO problem has been identified and corrected.
