Carbon Monoxide

Carbon monoxide, or CO, is a gas that can cause sickness, coma or death when it builds up in enclosed spaces. It is not seen, does not smell and cannot be tasted. Warning signs of poisoning include headache, nausea, vomiting, dizziness, drowsiness, and confusion, but no fever. Carbon monoxide exposure results in over 100 emergency department visits each year in Maine. Every home in Maine should have a carbon monoxide detector--about half of Maine homes do not have a carbon monoxide detector.
