Product information

    Carbon monoxide, or CO, is a poisonous gas emitted from household items that are defective, and as a result are burning fuel incompletely. Common sources of CO include ovens, boilers, BBQ's, open and solid fuel fires, gas or paraffin heaters and blocked or broken chimneys and flues. Carbon monoxide cannot be smelt, tasted or seen, and can be deadly - the only way to be alerted to CO is with an audible CO alarm.
