A home fire sprinkler system reduces heat, flames, and smoke within seconds. Fire sprinkler systems hide in walls with sprinkler heads running along the piping throughout your home.

When the air surrounding a sprinkler reaches a specific temperature, the heads closest to the fire activate and release anywhere from 10 to 25 gallons of water per minute.

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.

Regular inspections, using dry wood, and installing chimney caps help maintain efficiency and safety.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door.
