Symptoms of CO poisoning include the following:

WARNING

Any appliance that burns natural gas, propane gas, fuel oil, wood or coal is capable of producing carbon monoxide (CO). Carbon Monoxide (CO) is a gas which is odorless, colorless and tasteless but is very toxic. CO is lighter than air and thus may travel throughout the building.

BRIEF EXPOSURE TO HIGH CONCENTRATIONS OF CO, OR PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY RESULT IN CARBON MONOXIDE POISONING. EXPOSURE CAN BE FATAL AND EXPOSURE TO HIGH CONCENTRATIONS MAY RESULT IN THE SUDDEN ONSET OF SYMPTOMS INCLUDING UNCONSCIOUSNESS.

Symptoms of CO poisoning include the following:

 

dizziness

vision problems

shortness of breath

headache

loss of muscle control

unclear thinking

nausea

weakness

unconsciousness

The symptoms of CO poisoning are often confused with those of influenza, and the highest incidence of poisoning occurs at the onset of cold weather or during flu season. A victim may not experience any symptoms, only one symptom, or a few symptoms.

Suspect the presence of carbon monoxide if symptoms tend to disappear when you leave your home.

The following signs may indicate the presence of carbon monoxide:

Hot gasses from appliance, venting system pipes or chimney, escaping into the living space.

Flames coming out around the appliance.

Yellow colored flames in the appliance

Stale or smelly air.

The presence of soot or carbon in or around the appliance.

Very high unexplained humidity inside the building.

If any of the symptoms of CO occur, or if any of the signs of carbon monoxide are present, VACATE THE PREMISES IMMEDIATELY AND CONTACT A QUALIFIED

HEATING SERVICE COMPANY OR THE GAS COMPANY OR THE FIRE DEPARTMENT.

ONLY QUALIFIED, LICENSED SERVICE CONTRACTORS SHOULD PERFORM WORK ON YOUR BIASI RIVA HEAT ONLY BOILER.
