AS 1905.1-2005 -Components for the protection of openings in fire-resistant walls Fire-resistant doorsets

What are fire door regulations

Fire door regulations in Australian non-domestic buildings are primarily dictated by ordinances of the National Construction Code of Australia (NCC) or BCA Building Code Australia and specific Australian standards. These key elements include the BCA’s AS1428.1, which focuses on disabled compliance, Part D1 emphasizing on provision for escape, as well as Australian Standard AS 1905.1:2015

AS1428.1 provides the design norms to ensure access pathways, including doors, are accessible for people with disabilities. When it comes to fire doors, these regulations ensure all individuals, irrespective of their physical abilities, can safely evacuate a building in case of fire.

Part D1 of the BCA specifies the requirements for provision for escape or access to a safe place during emergencies, including during a fire. This section also includes the necessary measures and provisions to be taken into account when installing fire doors.

AS 1905.1:2015 sets out requirements for the construction, design, and installation of fire-resistant doorsets. It forms the backbone of fire door regulations ensuring fire doors comply with the necessary frameworks to prevent fires from spreading, maintain structural integrity, and protect escape routes in a fire event.

AS 1905.1 – 2015 “Components for the protection of openings in fire-resistant walls Fire-resistant doorsets”

Fire-resistant doorsets provide essential protection of openings in fire-resistant barriers. These doors are regulated under this Australian standard AS1905.1 – 2015.

AS1905.1 – 2015 specifically addresses fire-resistant doorsets used to safeguard openings in fire-resistant walls of buildings during a fire outbreak. The compliance with this standard guarantees that these doors can offer sufficient resistance to prevent the spread of fire, providing individuals enough time for evacuation.

Scope

AS1905.1 – 2015 is applicable to the design, construction, installation and maintenance of fire doors across Australia. It caters to stakeholders in the construction sector including:

  • Builders
  • Architects
  • Regulators
  • Door manufacturers

Definitions

  • Doorset: An assembly of components including the door leaf, door frame, associated hardware and any glazing or panels.
  • Fire resistance: The ability to resist a fully developed fire, while remaining intact and performing its given function during a particular period.
  • Fire Resistance Level (FRL): Expressed in minutes, the grading period that a building element, material, or structure when exposed to a standard fire test.

Requirements

This section outlines the requirements indicated in the AS1905.1 – 2015 standard.

  1. Doorset Design: The prescribed design of the doorset should be strictly followed. This includes elements such as:
    • The material of the door leaf and frame
    • The size and design of the glass vision panels
    • The details of the door hardware including hinges, latches, and closers.
  2. Installation: Fire doors need to be installed by licensed personnel who have been trained specifically in the installation of that particular product.
  3. Labelling: Each fire door must be labeled correctly to show that it has been tested and meets the stipulated requirements.
  4. Maintenance & Inspections: Fire doors should undergo regular inspections and maintenance by a competent person. Any repairs should also be conducted in accordance with the manufacturer’s specifications.

Compliance

Ensuring compliance with AS1905.1 – 2015 involves auditing to make certain that all aspects of the design, construction, installation, and maintenance requirements are met.

Steps for compliance include:

  1. Validation of the fire door’s design in compliance with the standard.
  2. Adherence to installation guidelines.
  3. Regular inspections and maintenance. (See below)

As per the Australian standards AS1851, all fire doors need to undergo testing at intervals of not more than every 6 months. The primary purpose of this testing process is to ascertain the doorsets’ functionality and efficiency.

An important aspect of FRL requirements is the duration for which a fire door can withstand heat exposure. According to the Australian Standards AS1905.1, a fire door has to endure heat exposure caused by a fire for 60 or 120 minutes. However, there are certain exceptions to this rule, such as doors that are permitted to be a –/60/30 self-closing fire door.

All doors, including their glazed parts, must not fail during the stipulated period for the FRL. This aims at ensuring the filled or glazed portion of the door can provide the same fire protection level as the rest part of the door.

It is crucial to comply fully with these regulations for the safety of the building occupants and to make certain that in the event of a fire, these doors offer a safe and secure evacuation route.

Each doorset, including both sides of double doorsets, should fully self-close from the fully open position and latch in its closed position.

All seals including edge, meeting and perimeter seals, should be inspected for integrity. Damaged or missing sections should be replaced.

All door hardware, including hinges, closer, latch & locks, need to be inspected for performance and wear & tear. Replace non-performing or worn out hardware.

Doorsets, including hardware, should be cleaned regularly to prevent dust and dirt accumulation that may impede performance.

Hinges, locks, and other moving parts should be lubricated at prescribed intervals to ensure smooth operation.

Proactive replacement of aged or defective components before failure.

Regular training and awareness programs for personnel to ensure they recognize the importance of maintaining the integrity of fire doors in their daily operations.

A record of these inspection results has to be kept on site for review by regulatory bodies. The log should detail the date of inspection, items inspected, faults identified, actions taken, due date for next inspection, and name/signature of the responsible personnel.

Summary

Compliance with AS1905.1–2015 is integral for fire safety in buildings. Stakeholders must adhere to design, construction, installation, and maintenance to ensure that in the event of a fire, these doors provide a safe and secure evacuation route. As each door set is expected to meet its stated Fire Resistance Level (FRL), it is imperative that consistent checks and maintenance are undertaken.
