'Tis the Season for Furnace Inspections
As we enter the home heating season, the U.S. Consumer Product Safety Commission (CPSC) urges
consumers to have a professional inspection of all fuel-burning appliances
including furnaces, stoves, fireplaces, clothes dryers and space heaters to
detect deadly carbon monoxide (CO) leaks.
These appliances burn fuels -- typically gas, both natural and liquefied
petroleum, kerosene, oil, coal and wood. Under certain conditions, these
appliances can produce deadly carbon monoxide. However, with proper
installation and maintenance, they are safe to use.
Carbon monoxide is a colorless, odorless gas produced by burning any fuel.
The initial symptoms of carbon monoxide poisoning are similar to the flu,
and include headache, fatigue, shortness of breath, nausea and dizziness.
Exposure to high levels of carbon monoxide can cause death.
"Carbon monoxide poisoning associated with using fuel-burning
appliances kills more than 200 people each year and sends more than 10,000
to hospital emergency rooms for treatment," said CPSC Chairman Ann
Brown.
CPSC recommends that the yearly professional inspection include checking chimneys, flues and vents for leakage and blockage by creosote and debris.
Leakage through cracks or holes could cause black stains on the outside of
the chimney or flue. These stains can mean that pollutants are leaking into
the house. In addition, have all vents to furnaces, water heaters, boilers
and other fuel-burning appliances checked to make sure they are not loose or
disconnected.
Make sure your appliances are inspected for adequate ventilation. A supply
of fresh air is important to help carry pollutants up the chimney,
stovepipe or flue, and is necessary for the complete combustion of any fuel.
Never block ventilation air openings.
CPSC recommends that every home should have at least one carbon monoxide
alarm that meets the requirements of the most recent Underwriters
Laboratories (UL) 2034 standard or International Approval Services 6-96
standard.
Recall Program to Replace Vent Pipes
Consumers should also have the vent pipes on their heating systems
inspected. In 1998, virtually the entire furnace and boiler industry
together with the manufacturers of high-temperature plastic vent (HTPV)
pipes joined with CPSC to announce a vent pipe recall program.
Take a look at U.S. Inspect's subsequent
story on the HTPV vent pipe recall to help
determine if you need to take action.
