Wet the roof and watch for outside fires caused by sparks. Have your chimney inspected before putting it back into service. Baking soda can be used to help suffocate a fire in the absence of a fire extinguisher. Check with your local fire department for the availability of fire extinguisher sticks. These devices emit large amounts of smoke to help smother a fire.
Chimney fires are a real and dangerous possibility when heating with wood.
A 1982 study by the U.S. Consumer Product Safety Commission reported that wood-burning appliance fires accounted for 20 percent of all residential fires and 5 percent of all fire deaths. While most chimney fires are confined to the chimney itself, the intense heat sometimes ignites surrounding building materials and furnishings. While we re talking safety, let's not forget disposal of ashes. Ashes must be stored in a metal container with a tight lid. The closed container should be placed on a non-combustible floor or on the ground well away from all combustible materials.
