If a light switch is off, it’s very unlikely to cause a fire. For a fire to start, the switch has to be on, activating an electrical current, and the wiring must be faulty. However, the malfunctioning light switch could cause an intermittent current to move across the electrical wire. This issue could become a fire hazard with another device connected to the wire. You should replace the bad light switch as soon as you notice it or call an electrician.

Beyond having an inspection, it’s important to do chimney maintenance at least annually to be certain the chimney is safe to use. Cleaning the flue of any built-up particles, creosote, and soot reduces the risk of fire. Fortunately, the cost of hiring a pro to do a chimney inspection often includes a chimney cleaning, so you may not have an extra expense for maintenance.

There are several maintenance tips you should take to ensure your pellet stove's safety and proper maintenance. You should vacuum the ash pan every week to prevent overflowing and clean the stove and surrounding vents every three to four months. It’s also important to get a professional inspection every year and install a carbon monoxide detector close to your stove. Be sure to dispose of hot ashes in a closed metal container; store it outside, away from the house. Only use the pellets recommended by your stove's manufacturer, and follow any cleaning and maintenance instructions.

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.
