As the weather becomes colder, families preoccupy their time with a variety of indoor activities which often take place in the comfort of their home. As the amount of time spent at home increases so does the use of heating and cooking equipment and fuels such as gasoline, wood, coal, natural gas, propane, oil and methane; all potential sources of carbon monoxide, an invisible, odorless, and colorless gas created when fuels burn incomplete; often referred to as the silent killer. Vehicles and generators can also produce dangerous levels of carbon monoxide when operating in an enclosed area such as an attached garage.
A person can be poisoned by a small amount of CO over a longer period of time or by a large amount of CO over a shorter amount of time. In 2010, U.S. fire departments responded to an estimated 80,100 non-fire CO incidents in which carbon monoxide was found; an average of nine such calls per hour. Since 2003, these incidents have increased by 96 percent. According to the National Fire Protection Association (NFPA), this increase can be attributed to the increased use of CO detectors which alert people to the presence of carbon monoxide.
Prince William County Department of Fire and Rescue (www.pwcgov.org/fire) in conjunction with NFPA suggests the following safety tips to protect you and your family from carbon monoxide poisoning:
- CO alarms should be installed in a central location outside each sleeping area and on every level of the home and in other locations where required by applicable laws, codes or standards. For the best protection, interconnect all CO alarms throughout the home.
When one sounds, they all sound.
- Follow the manufacturer’s instructions for placement and mounting height.
- Choose a CO alarm that has the label of a recognized testing laboratory.
- Call your local fire department’s non-emergency number to find out what number to call if the CO alarm sounds.
- Test CO alarms at least once a month; replace them according to the manufacturer’s instructions.
- If the audible trouble signal sounds, check for low batteries. If the battery is low, replace it. If it still sounds, call the fire department.
- If the CO alarm sounds, immediately move to a fresh air location outdoors or by an open window or door. Make sure everyone inside the home is accounted for. Call for help from a fresh air location and stay there until emergency personnel arrive.
- If you need to warm a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle or other fueled engine or motor indoors, even if garage doors are open. Make sure the exhaust pipe of a running vehicle is not covered with snow.
- During and after a snowstorm, make sure vents for the dryer, furnace, stove, and fireplace are clear of snow build-up.
- A generator should be used in a well-ventilated location outdoors away from windows, doors and vent openings.
- Gas or charcoal grills can produce CO — only use outside.
