New Heating and Air Conditioning units are extremely safe. Internal safety controls protect the equipment from damaging itself and they protect the home owners from certain catastrophic events. The equipment today is much safer than older equipment; however, there are dangers which the equipment cannot detect. The most severe dangers are CARBON MONOXIDE, NATURAL GAS and FIRE.
Fire is a less frequent problem than Carbon Monoxide or Natural Gas Leaks. Fire is infrequent due to safeties incorporated into furnaces. Furnaces will shut down if the temperature inside the furnace is higher than it should be. Occasionally a motor bearing will overheat and ignite wiring inside the furnace. If at any time you find smoke coming from your HVAC system call the fire department immediately. Never open a furnace compartment that is smoking or hot to the touch the compartments are often sealed and the fire will, in most cases, extinguish itself. If you are not in any danger and can shut off electrical and gas to the heating unit,do so. If there is any chance of endangering yourself call a professional and allow the professional to do their jobs.
IF YOU SMELL A STRONG NATURAL GAS SMELL LEAVE YOUR HOME AND CALL THE FIRE DEPARTMENT IMMEDIATELY. Natural Gas can leak at joints, through gas valves, and cracks in pipe. If you think you smell gas, call the fire department or the gas company. Your gas company has equipment that can detect even the smallest of leaks.
Carbon monoxide (CO) is an odorless, colorless gas that interferes with the delivery of oxygen in the blood to the rest of the body. It is produced by the incomplete combustion of fuels.
Carbon monoxide is produced as a result of incomplete burning of carbon containing fuels including coal, wood, charcoal, natural gas, and fuel oil. It can be emitted by combustion sources such as unvented kerosene and gas space heaters, furnaces, wood stoves, gas stoves, fireplaces and water heaters, automobile exhaust from attached garages, and tobacco smoke. Problems can arise as a result of improper installation, maintenance, or inadequate ventilation.
Carbon monoxide interferes with the distribution of oxygen in the blood to the rest of the body. Depending on the amount inhaled the gas can impede coordination, worsen cardiovascular conditions, and produce fatigue, headache, weakness, confusion, disorientation, nausea, and dizziness. High levels can cause death
The symptoms are sometimes confused with the flu or food poisoning, Infants, elderly, and people with heart and respiratory illnesses are particularly at high risk for the adverse health effects of carbon monoxide.
An estimated 1000 people die each year as a result of carbon monoxide poisoning and thousands of others end up in the hospital emergency rooms.
- Ensure that appliances are properly adjusted and working to manufacturers’ instructions and local building codes
- Obtain annual inspection for heating systems, chimneys, and flues and have them cleaned by a qualified technician
- Open flues when fireplaces are in use.
- Use proper fuel in kerosene space heaters
- Do not use ovens and gas ranges to heat your home.
- Do not burn charcoal inside a home, cabin, recreational vehicle, or camper.
- Make sure stoves and heaters are vented to the outside and that exhaust systems do not leak.
- Do not use unvented gas or kerosene space heaters in enclosed spaces
- Never leave a car or lawn mower engine running in a shed or garage, or in any enclosed space
- Make sure your furnace has adequate intake of outside air
Don’t ignore symptoms, especially if more than one person is feeling them. If you think you are suffering from carbon monoxide (CO) poisoning you should;
Get fresh air immediately. Open doors windows. Turn off combustion appliances and leave house.
Go to an emergency room. Be sure to tell the physician that you suspect CO poisoning.
Be prepared to answer the following questions: Is anyone else in your household complaining of similar symptoms? Did everyone’s symptoms appear about the same time? Are you using any fuel burning appliances in the home? Has anyone inspected your appliances lately? Are you certain they are working properly?
Carbon monoxide (CO) detectors can be used as a backup but not as a replacement for proper use and maintenance of you fuel-burning appliances. CO detectors are not generally considered to be as reliable as smoke detectors. You should not choose a CO detector solely on the basis of cost; do some research on different features available.
Carbon monoxide detectors should meet Underwriters Laboratories Inc. standards, have long-term warranty, and be easily self tested and reset to ensure proper functioning. For maximum effectiveness during sleeping hours, carbon monoxide detectors should be placed close to sleeping areas.
If Your CO Detector Goes Off:
- Make sure it is the CO detector and not smoke alarm
- Check to see if any member of your household is experiencing symptoms.
- If they are, get them out of the house immediately and seek medical attention
- If no one is feeling symptoms, ventilate the home with fresh air and turn off all potential sources of CO.
- Have a qualified technician inspect your appliances and chimneys to make sure they are operating correctly.
