- Make sure appliances are installed and operated according to the manufacturer's instructions
and local building codes. Most appliances should be installed by qualified professionals. Have the
heating system professionally inspected and serviced annually to ensure proper operation. The
inspector should also check chimneys and flues for blockages, corrosion, partial and complete
disconnections, and loose connections.
- Never service fuel-burning appliances without proper knowledge, skill and tools. Always refer to
the owner’s manual when performing minor adjustments or servicing fuel-burning equipment.
- Never operate a portable generator or any other gasoline engine-powered tool either in or near
an enclosed space such as a garage, house or other building. Even with open doors and
windows, these spaces can trap CO and allow it to quickly build to lethal levels.
- Install a CO alarm that meets the requirements of the current UL 2034 safety standard. A CO
alarm can provide some added protection, but it is no substitute for proper use and upkeep
of appliances that can produce CO. Install a CO alarm in the hallway near every separate
sleeping area of the home. Make sure the alarm is not covered up by furniture or draperies.
- Never use portable fuel-burning camping equipment inside a home, garage, vehicle or tent unless
it is specifically designed for use in an enclosed space and provides instructions for safe use
in an enclosed area.
- Never burn charcoal inside a home, garage, vehicle or tent.
- Never leave a car running in an attached garage, even with the garage door open.
- Never use gas appliances such as ranges, ovens or clothes dryers to heat your home.
- Never operate unvented fuel-burning appliances in any room where people are sleeping.
- Do not cover the bottom of natural gas or propane ovens with aluminum foil. Doing so blocks the
combustion air flow through the appliance and can produce CO.
- During home renovations, ensure that appliance vents and chimneys are not blocked by tarps or
debris. Make sure appliances are in proper working order when renovations are complete.
