There are a few things you should definitely avoid doing when it comes to fire doors to ensure they work properly and maintain their fire-resistant properties:
1. **Put open fire doors**: Fire doors are designed to automatically close in the event of a fire to prevent the spread of smoke and flames. Holding them open with wedges, rocks or any other object will prevent them from closing properly when needed, thus affecting their effectiveness.
2. **Remove the self-closing device**: Some fire doors are equipped with self-closing mechanisms such as door closers. Removing or tampering with these devices can prevent doors from closing automatically during a fire, which is critical for controlling fire and smoke.
3. **Install non-fire-resistant hardware**: Fire-rated doors are tested and certified with specific fire-resistant hardware, including hinges, locks, and handles. Installing non-fire-resistant hardware may compromise the integrity of the door, reducing its effectiveness during a fire.
4. **Paint Over Intumescent Seals**: Intumescent seals are typically installed around the edges of fire doors to expand in the presence of heat and seal the gap. Painting these seals can prevent them from functioning properly during a fire, allowing smoke and flames to pass through.
5. **Gap around the door**: Fire doors are installed with specific gaps and clearances to ensure normal operation and sealing in the event of a fire. Modifying these gaps or not maintaining them may affect the door’s ability to provide adequate protection.
6. **Use of Unsuitable Materials for Repairs**: If repairs are required to a fire door, fire resistant materials and components approved for use on fire doors must be used. The use of non-compliant materials may reduce the fire resistance rating of the door.
7. **Neglecting regular inspections and maintenance**: Fire doors should be inspected regularly to ensure they are functioning properly. Neglecting maintenance, such as not checking hinges, latches, and closures, can lead to malfunctions that render the door ineffective during a fire emergency.
8. **Ignore Building Codes and Regulations**: Fire doors must comply with specific building codes and regulations regarding their installation, maintenance and use. Ignoring these regulations can result in fines, penalties, or worse – putting building occupants at risk during a fire.
By avoiding these common mistakes and ensuring that fire doors are properly installed, maintained and used according to regulations, you can help maximize the effectiveness of your fire doors in protecting life and property during a fire emergency.
