WorkSafe Hazardous Substances Compliance

Stationary container system certifiers

Stationary Container Systems (SCS) & Location Compliance Certification

Keeping hazardous substance installations compliant in New Zealand requires more than routine tank inspections. Under the Health and Safety at Work (Hazardous Substances) Regulations 2017, many facilities are legally required to obtain Stationary Container System (SCS) and Location Compliance Certificates issued by an authorised WorkSafe Compliance Certifier.

At 3PI, we specialise in helping businesses achieve and maintain compliance through independent engineering assessments, inspections, and certification services. From fuel terminals and chemical processing plants to food manufacturing and bulk liquid storage facilities, our experienced Compliance Certifiers deliver practical solutions that protect your people, your assets, and your business.

Stationary Container System (SCS) Certification

A Stationary Container System extends well beyond the storage tank itself. It includes transfer pipelines, process vessels, pipework, valves, instrumentation, safety systems, and associated equipment that form part of the installation.

Our certification services include:

  • Existing and new Stationary Container Systems

  • Pre-2006 stationary container systems (up to 60,000 L)

  • Engineering review of new installations

  • Tank testing, inspections, modifications, and relocations

  • Secondary containment (bund) assessments

  • Transfer pipelines (wharf lines, bunker lines, etc)

  • Pipework integrity assessments

  • Tank foundations and structural supports

  • Pressure relief and emergency venting systems

  • Overfill prevention systems

  • Safety separation distance assessments

  • Tank identification and regulatory signage

Where compliance issues are identified, we provide practical engineering recommendations to help achieve certification efficiently and minimise operational disruption.

Location Compliance Certification

Our WorkSafe Compliance Certifiers assess hazardous substance locations to verify compliance with regulatory requirements for the storage and handling of dangerous goods.

Typical assessments include:

  • Hazardous substance inventories

  • Separation distances

  • Hazardous area classification

  • Emergency management requirements

  • Fire protection provisions

  • Secondary containment systems

  • Environmental protection measures

  • Security and controlled access

  • Hazardous substance compatibility

  • Signage and package compliance
