A chimney liner isn’t required for an outdoor fireplace; you don’t technically need one if the masonry chimney uses the proper dimensions and is built to code. However, a chimney liner does serve as a protective coating for the flue. Adding a liner could improve performance, safety, and durability. In short, while not necessary, it wouldn’t hurt.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

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.

Yes, fire extinguishers eventually expire. However, the good news is that a properly stored fire extinguisher can last a decade or longer. They don’t have an expiration date on the canister, but you can check the manufacturing date on the “UL” nameplate near the classification information. Maintenance will also give your fire extinguisher longevity. Check the gauge at the top of the extinguisher every month. You'll want to make sure the gauge needle is in the green section, and if a hose or nozzle has been used or damaged, you need to replace it.
