Use these additional tips to help ensure your safety. If you warm your car engine, do not leave the car in a garage, even if the door is open. Normal air circulation does not provide adequate ventilation. Have fuel-burning heating equipment checked each year before cold weather begins. This includes fireplaces, wood stoves and space heaters.
Ventilation is very important when using heating devices.
When using a fireplace, open the flue. Open a window slightly when using a kerosene or gas heater. Only use barbecue grills outside, never in the home or garage. Carbon monoxide detectors can provide an early warning of gas accumulating in the home. The National Fire Protection Association suggests installing a carbon monoxide detector in homes that have a fuel-burning appliance, fireplace or an attached garage.
