Choose hardwood, such as oak, maple or beech. It must be dry for at least six months. To check if it is dry, make sure that there are cracks in the ends of the logs.
In a building, firewood must be stored in a manner that does not interfere with an escape route, door, window or staircase. It must also be located away from the fireplace or wood stove. The distance to be respected and the quantity of firewood allowed in a building must be checked with the insurance company of the owner of the building where the wood is stored. In any case, it is preferable to bring only a few armloads of wood at a time into the building.
Outside a building, store the cords of wood away from the house. Cover the logs to protect them from the weather. Wet wood is detrimental to combustion and increases deposits of creosote, a carcinogen.
Safe way to dispose of hot ashes
The ashes must be placed in a metal receptacle with a raised base and a cover, all non-combustible.
They must be stored outdoors a minimum of one (1) metre from any combustible material. The ashes must be completely cold before you dispose of them.
Note that the ash can remain warm for up to 72 hours.
