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.

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.

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.

You should schedule a fireplace inspection at least once a year, per the National Fire Protection Association (NFPA). However, this is the minimum requirement even if you’re diligent with fireplace maintenance between uses. If you suspect your fireplace is malfunctioning, schedule one sooner to avoid fire hazards or the release of harmful emissions like carbon monoxide in your home.
