Status of Compliance Documents

Compliance Documents are prepared by the Department of Building and Housing in accordance with section 22 of the Building Act 2004. A Compliance Document is for use in establishing compliance with the New Zealand Building Code.

A person who complies with a Compliance Document will be treated as having complied with the provisions of the Building Code to which the Compliance Document relates. However, a Compliance Document is only one method of complying with the Building Code. There may be alternative ways to comply.

Users should make themselves familiar with the preface to the New Zealand Building Code Handbook, which describes the status of Compliance Documents and explains alternative methods of achieving compliance.

Defined words (italicised in the text) and classified uses are explained in Clauses A1 of the Building Code and in the Definitions at the start of this Compliance Document.

New Zealand Building Code

Clause F6 Visibility in Escape Routes

The mandatory provisions for building work are contained in the New Zealand Building Code (NZBC), which comprises the First Schedule to the Building Regulations 1992. The relevant NZBC Clause for Visibility in Escape Routes is F6.

SR2007/124

Clause F6-Visibility in escape routes

Provisions

Objective

F6.1 The objective of this provision is to help safeguard people from injury in escape routes during failure of the main lighting.

Functional requirement

F6.2 Specified features in escape routes must be made reasonably visible by lighting systems, other systems, or both, during failure of the main lighting.

Performance

F6.3.1 Specified features in escape routes must, when the systems for visibility are at their design level, be reasonably visible.

F6.3.2 The systems for visibility must operate to the following percentages of their design levels within the following times after failure of the main lighting:

(a) 80% in 0.5 seconds in locations (examples of which are given by performance F6.3.3) where there is a high risk of injury due to delay in operation of the systems for visibility; and
(b) 10% in 0.5 seconds, and 80% in 30 seconds, in stairs and in locations that are unfamiliar to users; and
(c) 10% in 20 seconds, and 80% in 60 seconds, in all other locations.

F6.3.3 Examples of locations (referred to in performance F6.3.2(a)) where there is a high risk of injury due to delay in operation of the systems for visibility include:

Limits on application

Requirement F6.2 does not apply to Detached Dwellings, household units within Multi-unit Dwellings, Outbuildings, or Ancillary buildings.

Performance F6.3.1 does not apply to specified features in the initial 20 metres of an escape route if the risk of injury, or impediment to movement of people, due to the specified features not being visible is low (for example, because people are familiar with the escape route, the escape route is level, and people do not require assistance to escape).
