Fireplace Dangers

Maintenance for Fireplace Safety

Safe Supply of Fireplace Air

A fireplace fire requires about 5 times as much air as most houses need for liberal ventilation. With today's tightly-constructed houses incorporating weather-stripped doors, caulked windows and self-closing exhaust vents, a fireplace can set up reverse draft and suck poisonous carbon monoxide fumes from combustion-type (natural gas, etc.) water heaters or furnaces and discharge them into the living area. In tight homes, the fireplace may also consume enough oxygen from the air in the house to cause problems to occupants. To be safe, a positive source of outside air should be supplied to all fireplaces and wood-or-coal burning stoves to bring in enough fresh air for efficient burning. This can be provided by installing an outside air vent or opening a window when the fireplace or stove is being used. To keep smoke from entering the room, turn off kitchen and bathroom exhaust fans and close the registers of forced air heating systems which are near the fireplace.
