Certified fire door inspectors should inspect fire doors. These professionals receive training to specifically assess the condition, functionality, and compliance of fire doors. They often hold credentials from groups like the Door and Hardware Institute (DHI) or the International Fire Door Inspector Association (IFDIA). While fire marshals won’t usually do hands-on inspections, they’ll check that doors are being maintained properly during routine safety audits. If a building relies on fire doors for code compliance, it needs someone who understands the details—the difference between a cosmetic issue and a safety failure—and standards to sign off with confidence.

While your forced heating system runs, it can pick up dirt, dust, hair, and other particles from inside your house. Changing your furnace filters regularly is key to preventing this debris from getting stuck in your ducts and swirling around your home. With some types of furnaces, there’s also the potential for carbon monoxide leaks. However, staying up-to-date with your HVAC inspections and installing carbon monoxide sensors can help mitigate this risk.

The primary disadvantage of a ventless fireplace is that it doesn’t have an exterior venting system. This means that the byproducts from combustion are emitted into your home, which raises some safety concerns. In addition, ventless gas fireplaces produce moisture as they burn—and if there’s no ventilation, you could end up with a mold problem.

You should change the batteries in your smoke detectors at least once per year. Mark it on your calendar or make it a holiday or birthday tradition so that you always remember it. You should also be testing your smoke alarms monthly to ensure they’re working properly and can alert you in case of an emergency.
