Carbon Monoxide - The deadly threat of carbon monoxide can be stopped by a yearly professional inspection.
Washington, D.C. -- Having your home inspected each year at the beginning of the heating season can help avoid deadly carbon monoxide gas from leaking into your home, according to Chairman Ann Brown of the Consumer Product Safety Commission.
"CO poisoning from the use of fuel burning appliances kills at least 200 people each year and sends more than 5,000 to hospital emergency rooms for treatment," Brown said. "Consumers can avoid this tragedy by having their fuel-burning appliances inspected by a qualified technician each year, and by purchasing and installing CO detectors that meet the requirements of the Oct. 1, 1995 Underwriters Laboratories standards."
CO is a colorless, odorless gas produced by burning any fuel. The initial symptoms of CO poisoning are similar to the flu, and include dizziness, fatigue, headache, nausea and irregular breathing. High level exposure to CO can cause death.
"Modern heating equipment is sophisticated and requires special training and tools for proper maintenance," Brown said. "CPSC recommends that consumers should not service their own appliances, but instead have a qualified professional perform an inspection."
A yearly inspection of your home by a professional should include a careful look at the following sources of carbon monoxide:
"Carbon monoxide is a deadly threat, but it can be avoided by having a yearly professional inspection of your home fuel burning appliances and by installing a CO detector that meets the most recent UL standards," Brown said.HOW DOES CO ENTER THE HOME?
Carbon monoxide can escape from any fuel-burning appliance, furnace, water heater, fireplace, woodstove, or space heater.
Most newer homes are built very air-tight, thus cutting down on the supply of fresh air to your furnace - and creating an oxygen starved flame. Tight closing replacement windows and doors, as well as additional insulation can cause similar problems in older homes.
Carbon monoxide can spill from vent connections in poorly maintained or blocked chimneys. If the flue liner is cracked or deteriorated, CO can seep through the liner and into the house - slowly creeping up to dangerous levels. If a nest or other materials restrict or block the flue, CO will mostly spill back into the house.
Improperly sized flues connected to new high-efficiency furnaces and water heaters can also contribute to CO spillage. (Many new furnaces and water heaters are installed using the existing chimneys which may be the wrong size to allow the furnace to vent properly.)
Warming up vehicles in an attached garage, even with the garage door opened, can allow concentrated amounts of CO to enter your home through the car port door or near-by windows.
WHAT TO DO IN A CO EMERGENCY.
If you are suffering from chronic flu-like symptoms, see your doctor and ask him if it could be a low-level CO poisoning.
If you have a CO detector, and it alarms, open windows and ventilate your home w/ fresh air, have your heating system checked by a professional.
If your alarm sounds and you are feeling drowsy or dizzy, leave the house and call 911 from your neighbors home. You may need medical attention for CO poisoning.
Carbon Monoxide Detectors w/ PPM Displays and Battery Backup
Although all home carbon monoxide detectors use an audible alarm signal as the primary indicator, some versions also offer a digital readout of the CO concentration, in parts per million.
Typically, they can display both the current reading and a peak reading from memory of the highest level measured over a period of time.
The digital models offer the advantage of being able to observe levels that are below the alarm threshold, learn about levels that may have occurred during an absence, and assess the degree of hazard if the alarm sounds.
They may also aid emergency responders in evaluating the level of past or ongoing exposure or danger.
