The Importance of Fire Door Resistance Ratings in Building Safety
Fire resistance ratings are crucial for ensuring the safety and integrity of building elements, especially in construction and existing infrastructure.
Understanding the fire resistance of operational fire doors in older buildings is essential, as these doors help secure escape routes and must be part of any fire risk assessment.
This is a legal duty under the Regulatory Reform Fire Safety Order (RRFSO) 2005 in England and Wales.
The Fire Safety Act 2021 expands the scope of the RRFSO to include flat entrance doors and fire doors in common areas of multi-occupancy residential buildings, mandating their inclusion in fire risk assessments. Additionally, the Fire Safety (England) Regulations 2022, effective from 23 January 2023, introduce further responsibilities for Responsible Persons in multi-occupancy buildings, including requirements for informing residents about fire doors and conducting regular checks.
Challenges in Establishing Fire Resistance
One major challenge for Responsible Persons is the lack of records for fire doors in older buildings, making it difficult to verify their fire resistance ratings. Without documentation or identifiable markings, assessing the doors’ fire resistance becomes complex and reliant on expert opinion, as many construction details may be hidden.
Maintenance also poses issues; alterations and replacements over time may not be well-documented, complicating assessments of the doors’ current condition and compliance. Under Article 17 of the RRFSO, maintaining fire safety provisions, including fire doors, is a legal duty. If the fire resistance rating cannot be verified, the doors must undergo thorough inspection and assessment.
Replacing Inadequate Fire Doors
If fire doors are found to have inadequate or indeterminable fire resistance, appropriate fire-resisting doorsets must be specified and installed as replacements. It’s essential that these replacements are supported by solid test evidence. However, a test report alone only covers the specific designs tested; it doesn’t guarantee that the product supplied matches the tested design or that any design changes are acceptable.
For replacements, it’s recommended to source from manufacturers that adhere to accredited third-party certification schemes. These voluntary schemes provide additional assurance that products meet required fire resistance standards, offering benefits such as:
1. Independent verification of the product’s construction through sampling before testing.
2. Regular inspections of factory production processes to ensure consistency with the tested product.
3. Marking and labelling to identify performance and manufacturer, aiding in risk assessment and maintenance.
4. Periodic audit testing to confirm ongoing product performance.
Certification is typically extended through an assessment by a qualified body, such as a UKAS-accredited laboratory, ensuring the product’s conformity to the necessary standards.
Installation Matters
The installation of replacement doorsets is as crucial as the doors themselves. Poor installation can undermine the fire resistance rating, making the doors ineffective and non-compliant. Accredited certification schemes for installation offer additional assurance on the quality and compliance of the installation process.
Best Practices for Building Managers
Building owners and managers must ensure that fire resistance ratings of fire doors are diligently verified. If ratings are unclear, suitable replacements must be sourced and properly installed, supported by robust test evidence and, ideally, third-party certification. This approach ensures optimal safety and compliance with legal requirements.
