No material is genuinely fireproof, so there’s no genuinely fireproof safe. Any material would break down if exposed to a hot enough temperature for long enough. That said, safes can withstand certain house fires. Manufacturers use the term “fireproof” synonymously with “fire resistant.”

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.

When a carbon monoxide alarm goes off, you should always take it seriously. Infrequent and occasional chirps often point to a low battery, a faulty device, or dust buildup (this usually affects smoke detectors and not standalone CO detectors). A continuous alarm signals an emergency, and you should immediately evacuate and call 911. When it comes to carbon monoxide in your home, it’s better safe than sorry.

Testing a fire extinguisher by discharging even a small amount will void the warranty on the product. Pushing down the pressure pin on top and waiting to see if it pops up is the best way to ensure it’s still pressurized. If you’re concerned about your extinguisher, hire an expert for a professional inspection.
