Lightning can cause massive damage, fires, and openings for other threats like bugs or fungal diseases. Barring any large fires or explosions, it’s difficult to tell how much damage a lightning strike has done until after a thorough inspection. Contact local authorities immediately if lightning strikes a tree in your yard and it causes a fire or explosion.

You should only use water to put out a fire in your fireplace in an emergency situation. Even then, it is better to use a fire extinguisher to put out a fire quickly. Make sure every room in your house that has a fireplace also has a fire extinguisher—and that everyone in your household knows how to use one.

If a light switch is off, it’s very unlikely to cause a fire. For a fire to start, the switch has to be on, activating an electrical current, and the wiring must be faulty. However, the malfunctioning light switch could cause an intermittent current to move across the electrical wire. This issue could become a fire hazard with another device connected to the wire. You should replace the bad light switch as soon as you notice it or call an electrician.

Fire doors are constructed to have certain resistance levels regarding fire. A traditional door can typically resist fire for less than one minute, whereas fire doors can resist it for 30 to 120 minutes, depending on the fire door rating. Fire doors give you and your family a better chance of safely escaping during a fire than standard doors.
