What are the proposed changes?

We’re proposing changes to NCC Volume One to minimise the risk that a person becomes trapped in a fire-isolated exit.

These changes include:

  • Expanding the list of building classifications to which the provisions for re-entry from fire-isolated exits relate (D3D27(1)).
  • Requiring at least every second floor where re-entry is not available, to include a sign stating where they can re-enter the building. This would apply to fire-isolated exit doors fitted with a fail-safe device that automatically unlocks the door upon the activation of fire alarm. (D3D27(2)(a)(ii)).

Why are these changes proposed?

People who inadvertently enter a fire-isolated exit may become disoriented or potentially trapped. Examples of instances where people were trapped in these exits show the results can be catastrophic in terms of their health, and in some cases lead to a fatality.

How were the changes developed?

These changes stem from a Proposal to Change the NCC we received from a state government body. The proposal included evidence of fatalities and adverse health outcomes for people who had been trapped in fire-isolated exits.

We undertook a technical assessment of the proposed changes that showed expanding the provisions to a broader set of building classifications and introducing signage requirements could address the problem.

Who has been involved?

We consulted with members of our peak technical committee, the Building Codes Committee.

What are the impacts?

These cost-effective changes will mean safer fire-isolated exits from buildings, such as apartment buildings, hotels and shops, and will minimise the risks associated with someone becoming trapped.

To read the full details of the changes, please review the NCC 2025 Volume One PCD and Section A.
