• WHAT YOU SHOULD KNOW ABOUT CO Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas.
It is a cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn infants with no effect on the mother. • • An alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. Where bedrooms are separated and audibility of the alarm to occupants within the bedroom area could be seriously impaired, more than one alarm could be needed. • In general, install combination Smoke, CO and Gas Alarms: • WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS. • In or near bedrooms and living areas or wherever you suspect a smoke, natural gas or CO exposure is likely.
