Description

C Protection from Fire Verification Method C/VM2 Second Edition provides a performance-based framework for demonstrating compliance with Clauses C1 to C6 of the New Zealand Building Code through fire engineering design.

It is intended for buildings where a verification method is preferred over prescriptive acceptable solutions particularly for complex or unique fire safety designs.

The second edition references the Building Product Specifications and includes minor amendments for clarity and usability without altering performance requirements.

Scope

This verification method can be used for the specific design of buildings with:

  • a) simultaneous evacuation procedures where occupants evacuate immediately to the outside; and
  • b) typical fire growth rates.

Items outside the scope of this document

This verification method does not include buildings that:

  • a) do not have simultaneous evacuation schemes that evacuate immediately to the outside; or
  • b) require a managed evacuation; or
  • c) contain fire hazards that are not defined in Part 2. Rules and parameters for the design scenarios.

The control of hazardous substances is not covered by this verification method and it does not  provide for any use, storage or processing of hazardous substances. Compliance with Verification Method F3/VM1 and the Hazardous Substances and New Organisms Act 1996, and the Health and Safety at Work (Hazardous Substances) Regulations 2017 is required where applicable in addition to the requirements of this verification method.
