The Importance of Keeping Fire Doors Closed

How Fire Doors Protect Your Building

A closed, latched fire door divides a building into fire-resistant sections. Each section holds back flames and smoke, keeping them from reaching the rest of the building. That containment protects hallways and stairwells. It gives everyone inside more time to get out safely. It also helps firefighters do their job. In many cases, closed fire doors greatly reduce property damage along with the time a business spends shut down.

The National Fire Protection Association (NFPA) sets fire door standards. NFPA 80 requires fire doors to stay in good working order, free of anything that blocks them from closing. It also calls for fire door assemblies to be inspected and tested at least once a year. A door that’s propped open can’t do its job. Even a small gap lets smoke and heat move freely into other parts of the building, defeating the whole purpose of the fire-rated barrier.

That’s why every employer should know the risks of open fire doors, plus a few simple habits to prevent them.

The Risks of Open Fire Doors

When fire doors stay open, smoke spreads quickly into nearby spaces. Visibility drops, raising the risk of smoke inhalation for anyone trying to get out. Flames and heat reach areas a closed door would have protected.

Exit routes and stairwells can fill with smoke, cutting off safe ways out of the building. The chance of injuries rises sharply. Firefighters arrive to find a larger fire that’s much harder to control.

The fire also reaches more of the building. Property damage climbs, repairs take longer and reopening gets pushed further out.

What Open Fire Doors Mean for Your Insurance

From an insurance perspective, a propped-open fire door can turn a contained fire into a major claim. Damage spreads further, repairs cost more and downtime stretches longer. Business interruption losses can grow quickly. Keeping fire doors closed protects your people, your property and your ability to stay open. It also shows insurers your business takes risk management seriously.

Why Fire Doors End Up Open

Employees rarely prop a fire door open to create a hazard. In most cases, everyday pressures are to blame.

Comfort is a common reason. In spaces with poor airflow or uneven heating and cooling, an open door can feel like an easy fix. Convenience is another. When people move carts, pallets and equipment through a doorway all day, propping the door open saves time. Some employees see a closed fire door as a nuisance that slows down routine tasks.

Many workers simply don’t know what fire doors do. Without that understanding, it’s easy to underestimate the danger of leaving one open. Broken equipment plays a part too. A damaged or worn self-closing mechanism may keep a door from shutting properly. Instead of reporting the problem, employees often just leave the door open.

Best Practices for Fire Door Safety

Fire doors work best with consistent use, regular maintenance and clear expectations for everyone in the workplace. A few simple habits can reduce fire risk, support code compliance and limit the size of a loss.

• Keep fire doors closed. Never prop a fire door open. The only exception is a door with an approved automatic hold-open device. These devices release the door when a fire alarm sounds, letting it close on its own.
• Make sure doors close fully. Every fire door should close all the way and latch with nothing in its path. A door that doesn’t latch can’t hold back fire and smoke.
• Inspect fire doors regularly. Check doors and their hardware according to NFPA standards, at least once a year. Look for damage, missing parts and anything that could keep a door from working.
• Repair problems right away. Fix damaged hinges, closers, seals and latches promptly. Small problems can weaken a door’s fire rating.
• Train your team. Help employees understand why fire doors matter. When people know how a closed door protects them, they’re far more likely to keep it shut.
• Post clear signs. Simple, visible signs remind everyone to keep fire doors closed.
• Add fire doors to your safety checks. Include fire doors in routine safety audits and facility inspections. Regular checks build accountability and keep your building in compliance.

A Simple Step With a Big Payoff

Keeping fire doors closed costs nothing. It’s one of the most effective ways to protect your people, your building and your business. When used as designed, fire doors save lives, limit damage and help you get back to work faster. When they’re propped open or neglected, a small fire can become a serious, costly loss.
