Regular inspections, using dry wood, and installing chimney caps help maintain efficiency and safety.

After a house fire, you should not reenter your home unless the fire crew has told you it’s safe to do so. In the longer term, you should not attempt to make repairs to the house on your own. Professional crews are trained to clean up after a fire (including smoke and soot damage), dry out any water damage from the firefighter crews, and make the necessary structural, plumbing, and electrical repairs—and this is all likely covered by insurance.

No, it is not safe to use an outlet that sparked. A spark from an outlet could indicate a short circuit, loose or frayed wiring, or other serious damage. Continuing to use an outlet that sparks can increase the risk of electrical shock, electrical fires, and other hazards. It's important to turn off the power to the outlet at the circuit breaker if possible and avoid using the outlet until a licensed electrician has inspected and repaired it.

Your smoke detector might be too high in some homes or circumstances to reach yourself. If you feel unsafe getting on a ladder to replace your hardwired smoke detector, call a licensed electrician or local handyman to knock this project off your to-do list. If you have a battery-operated smoke detector, your local fire department can change the batteries or help you replace the detector—just make sure you call the non-emergency number.

In any case, do not let this project go unresolved, as it could turn into a huge safety issue.
