Compliance Certifiers are the only people approved by WorkSafe to inspect sites and issue compliance certificates required under the Regulations that confirm:

  • equipment meets the standards in the Regulations.

  • locations where hazardous substances are stored or used when the quantities held trigger certification meet the requirements relating to safe design and position of dangerous goods on site.

  • workers handling hazardous substances have appropriate qualifications.


Our Certifiers have had extensive experience with the Regulations and the practical issues arising from compliance. Where we do not breach the “conflict rules” in the Regulations, we can provide consultancy services in relation to many aspects of site design and process.

The Regulations are promulgated pursuant to the Health and Safety At Work (Hazardous Substances)  Regulations 2017  (HSWA).




Stationary tanks or process containers that hold hazardous liquids or gases over specified quantities require a Stationary Container System Compliance Certificate that confirms compliance with specific HSWA requirements, which can include:

  • the design and construction of the tank or process container.

  • requirements for emergency management, including any secondary containment.

  • signage.


Location Compliance Certificates are required for flammable, oxidising, toxic or corrosive substances above certain quantities. To obtain a Location Compliance Certificate a business must demonstrate that the site complies with HSWA requirements specified in the regulations.

Trigger quantities for a Location Certificate are:

  • 50 litres for any high-risk solvent or flammable liquid (in use).

  • 250 litres in a storage situation.

  • 100 kg for any high-risk flammable gas (such as LPG, methane, etc).

The trigger quantity for chlorine for a Compliance Location Certification is:

  • 500 kg or litres when in storage.

  • 50 kg or litres when in use.


Class 6.1A/B/C and Class 8.2A/B substances now require formal certification by a Compliance Certifier.

These audits are comprehensive and may require from half a day to a full day. Our Compliance Certifiers will examine your processes and personal protective equipment, storage locations, staff training and emergency preparedness to ensure you are compliant with the new Regulations.


Acutely toxic substances, 6.1 A/B, require certified / approved handler certification.

Class 6.1A/B above certain thresholds now requires formal location compliance certification.

If your site has substances that trigger the need for qualified Certified Handlers (such as Class 6.1A / B substances that are not agrichemical, fumigant, veterinary medicine and vertebrate toxics) a qualified Approved Handler or Certified Handler must be present or available on-site at all times.

A Certified Handler’s Certificate is a new requirement under the Regulations, different from the past Approved Handler Certificate. If you have any questions or concerns, please do not hesitate to contact us.


A Certified Handler must know and be able to explain:

  • the purpose and principles of the HSWA Act.

  • the HSNO classification system.

  • the HSWA controls (safety items).

  • the importance of safety data sheets (SDS).

  • the enforcement and potential fines, etc.

  • the handling procedures for the particular substance.

  • all precautions required to prevent injury to a person or damage to the environment by any of the substances.

  • the procedures to be followed in the event of an emergency.
