Home fires are common during the holidays, many the result of holiday lighting.
Test your smoke detectors to make sure they’re working properly and replace any that have stopped working.
Keep live trees adequately watered. If you can pull needles from a tree with little effort, the tree needs more water.
If you’re using an artificial tree make certain that it is fire rated.
Look carefully at all strings of lights before you hang them. Replace any with frayed wiring. Covering frayed wires with electrical tape isn’t worth the risk to your home.
