One of the best ways to know your chimney is good to go on any given night is to simply look up into your flue with a flashlight. If you see a thick buildup of creosote—a shiny, dark substance that looks like tar—it’s best to have your fireplace professionally cleaned before you go ahead with the burn. Additionally, having your fireplace professionally inspected once per year can also help increase your peace of mind and keep your family and your home safe.

Short circuits can cause fires, electrical burns, and electrocution, which can lead to serious injury or even death. That’s why it’s important to take preventative measures to prevent short circuits, like getting annual electrical maintenance and an electrical inspection every two to five years, depending on the age of your home.

You should not attempt to disable a smoke alarm unless you’ve already activated a replacement unit. To stop a hardwired smoke alarm from beeping, reset the device or silence the alarm. If you’re removing a hardwired alarm, shut off the power, turn the unit counterclockwise to remove it from the ceiling, and disconnect the wiring.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.
