Mechanical

Pressure Equipment, Cranes and Passenger Ropeways

These activities are promulgated under the Health and Safety in Employment Act 1999 and administered by the Department of Labour. This Act specifies inspection bodies must be currently accredited to a recognised industry standard (AS/NZS ISO/IEC 17020) by a recognised Accreditation Body (IANZ). Department of Labour engineers are invited to every assessment and fulfil the role of Technical Experts.

Types of functions

  • Pressure equipment for industrial use, including: Boilers used in large buildings e.g. refineries; power stations; dairy, meat and other processing factories; hospitals, etc.
  • Traction engines
  • Compressed air at petrol stations, dry cleaners, etc.
  • Cranes for commercial uses, including:
  • Tower cranes e.g. construction sites, etc.
  • Mobile cranes e.g. container wharves, straddle carriers, high lift, etc.
  • Fixed to vehicles e.g. road carriers, boats, etc.
  • Workshops e.g. manufacturing, storage, etc.

Commercially operated passenger ropeways, including:

  • Gondolas e.g. Rotorua, Queenstown, Port Hills (Christchurch).
  • Cable cars.
  • Ski lifts.

Pipelines

High pressure gas and liquids transmission pipelines are promulgated by the Health and Safety in Employment (Pipelines) Regulations 1999, covered by the Health and Safety in Employment Act 1992 and administered by the Department of Labour. Major pipelines are operated by the petroleum industry throughout the country.

All pipelines are required to operate with a current Certificate of Fitness issued by a recognised Certifying Authority (Inspection Body), the purpose of which is to demonstrate that a designated pipeline and associated equipment is “fit for purpose”, covering design, construction, operation, maintenance and/or abandoned. Certifying Authorities are required by regulation to be accredited to a recognised industry standard (AS/NZS ISO/IEC 17020) by IANZ.

Off-Shore Structures

These are fixed installations promulgated in the Health and Safety in Employment (Petroleum Exploration and Extraction) Regulations 1999, covered by the Health and Safety in Employment Act 1992, and administered by the Department of Labour.

A verification scheme is operated to ensure that safety critical elements:

  • Remain in good repair and condition; and
  • Where they are yet to be provided, will be suitable.

Certifying Authorities carry out inspections and issue certificates of fitness; they are required by regulation to be accredited to a recognised industry standard (AS/NZS ISO/IEC 17020) by IANZ.

Fire Sprinklers and Alarms

There are three standards that require inspections to be undertaken by organisations accredited to ISO 17020:

  • NZS 4515: Design, material, fabrication and installation of fire sprinkler systems for residential occupancies; and the periodic testing and maintenance
  • NZS 4512: Design, installation, extension, modification, commissioning, testing and maintenance for fire detection and alarm systems in buildings.
  • NZS 4541: Design, performance, installation and maintenance of automatic fire sprinkler systems in buildings or structures or in fire cells which form part of a building.
