In some cases, you can use a fireplace once the insert has been removed. However, before burning a fire, you must have a professional inspect it and the chimney to make sure they're functioning properly and no damage has occurred from removing the insert. That’s because using a fireplace without an insert could create fire hazards due to issues with airflow and heat dispersion, depending on the fireplace design and material. A professional can advise on whether you should make certain repairs or modifications before using your fireplace as an open hearth.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

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.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.
