Can Internal Fire Doors Be Locked?

Key Takeaways

Introduction

Fire doors play a crucial role in protecting lives and property during a fire by containing the spread of smoke and flames. As such, it's essential to ensure that these doors function properly and are not compromised by incorrect hardware or locking mechanisms. A common question that arises is whether internal fire doors can be locked. In this blog post, we'll explore the regulations surrounding fire door locks and discuss the appropriate locking solutions for these critical safety features.

Fire Door Regulations

According to UK building regulations, fire doors should be kept closed and unobstructed at all times to maintain their effectiveness in preventing the spread of fire and smoke. While it is not illegal to lock a fire door, it is essential to use the appropriate locking mechanisms that do not impede the door's ability to function as intended during a fire.

The main concern with locking fire doors is that they may prevent or delay the escape of occupants during an emergency. Therefore, any locks used on fire doors must be carefully considered and comply with relevant safety standards.

Suitable Locking Solutions for Fire Doors

1. Fire-Rated Locks

Fire-rated locks are specifically designed for use on fire doors. These locks have been tested to ensure they maintain the fire door's integrity and do not compromise its fire-resistant properties. When selecting a fire-rated lock, ensure that it is compatible with your specific fire door and has been independently tested and certified.

2. Panic Hardware

In public buildings or commercial spaces, panic hardware is often used on fire doors to allow for quick and easy evacuation in an emergency. Panic bars or push pads release the lock when pressed, enabling occupants to exit swiftly without the need for a key or special knowledge.

3. Electromagnetic Locks

Electromagnetic locks, also known as maglocks, use an electromagnetic force to secure the door. In the event of a power failure or when triggered by a fire alarm system, these locks automatically release, allowing the door to be opened freely. This ensures that the fire door remains unlocked and accessible during an emergency.

Locks to Avoid on Fire Doors

1. Standard Locks

Standard locks, such as nightlatches or mortice locks, should not be used on fire doors as they can impede emergency access. These locks may require a key to open from both sides, which can delay evacuation and put lives at risk during a fire.

2. Unapproved Modifications

Any modifications to a fire door, including the addition of non-fire-rated hardware or the alteration of the door's structure, can compromise its fire-resistant properties and may render the door non-compliant with safety regulations.

Conclusion

In summary, while it is possible to lock internal fire doors, it is crucial to use appropriate locking solutions that comply with fire safety regulations and do not hinder the door's ability to function effectively during an emergency. Fire-rated locks, panic hardware, and electromagnetic locks are all suitable options for fire doors, depending on the specific application and building requirements.
