Ashes can hold embers long after a fire appears out. Let them cool, then place them in a metal container with a tight-fitting lid; store it outdoors away from the home and combustibles, following fire-safety guidance.

Ontario recommends annual professional inspection and cleaning of fuel-burning appliances, chimneys and vents before cold weather. The technician can advise whether cleaning is needed based on the system’s condition and use.
