As we enter into the cold, harsh winter weather over the coming weeks, we will tend to find ourselves spending more and more time indoors. As we start to crave the warmth and heat of our homes we should also think of some of the potential hazards we may become exposed to . . . Number 1 being the silent killer — Carbon Monoxide.

The presence of Carbon Monoxide (CO) in our homes is extremely dangerous and can have fatal con-sequences. Carbon monoxide is an odorless, colorless and toxic gas. It is impossible to see, taste or smell and so has the potential to affect you before you are aware it is even in your home. At low levels of expo-sure, carbon monoxide causes health effects that can be mistaken for the flu. The symptoms associated with exposure to this harmful gas include headaches, dizziness, disorientation, nausea and fatigue. The effects of carbon monoxide exposure can vary greatly from per-son to person depending on age, overall health and the concentration of the gas and length of time the person is exposure to it.

Leaking chimneys, back drafting from furnaces, kerosene heaters, gas water heaters, wood stoves, fireplaces and tobacco smoke are some of the potential sources of carbon monoxide. Worn or poorly adjusted and maintained combustion devices (e.g., boilers and furnaces) can also be significant sources along with the flue being improperly sized, blocked, disconnected, or leaking.

However there are many steps you can take to reduce exposure to this sometimes harmful gas:

• Purchase a carbon monoxide detector.
• Have a qualified technician inspect chimneys and vents yearly for cracks, blockages (e.g., bird’s nests, twigs, old mortar), corrosion or holes.
• Check fireplaces for closed or blocked flues.
• Check with a qualified technician before enclos-ing heating and hot water equipment in a smaller room to ensure there is adequate air for proper combustion.
• Never use propane or natural gas stove tops or ovens to heat your home.
• Never start a vehicle in a closed garage; open the garage doors first.
• Avoid the use of a kerosene space heater indoors or in a garage.
• Regularly clean the clothes dryer ductwork and outside vent cover for blockages such as lint, snow, or overgrown outdoor plants.

A carbon monoxide detector is a very valuable piece of equipment for detecting the presence of carbon monoxide. However, they should only be seen as a second line of defense for protecting you and your family but every household should have at least one.

So as the temperatures drop around us and we spend less and less time outdoors and more indoors, think about the silent killer that may be building up in your home and take all precautions available to protect you and your family.
