Mike Page the Grand Junction Fire Department’s Public Information Office demonstrates the new carbon monoxide breathalyzer this morning at Fire Station No.1.The new device at the Grand Junction Fire Department allows fire fighters to test people who may have been exposed to carbon monoxide poisoning. While calls are up as the detectors go off, the department has no way of telling if a person has been affected. The breathalyzer is a new tool to measure how much a person has taken in.
