WorkSafe Hazardous Substances Compliance
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.
-
We conduct comprehensive risk assessments to identify potential hazards associated with the use of stationary containers, including evaluating the impact of hazardous substances, the integrity of the containers, and environmental risks.
-
Our compliance certifiers perform thorough inspections of stationary container systems to verify their integrity and operational safety. If they’re satisfied, they issue certification, confirming that the systems meet safety standards.
We provide detailed reports documenting our findings, including any identified deficiencies, recommended corrective actions and compliance status.
-
You must have a comprehensive compliance plan for existing stationary container systems that hold up to 60,000 litres, under Regulation 17.91 and Schedule 1 Clause 45 of the Health and Safety at Work (Hazardous Substances) Regulations 2017.
We can provide a plan that specifies the measures necessary to ensure that your stationary container systems meet current health and safety regulations. This plan will help you effectively manage the risks associated with the storage and handling of hazardous substances, and ensure the safety of your employees, the public and the environment.
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
