Home - What are the requirements for storing significant quantities of hazardous chemicals?
June 23, 2022 on chapter Chemical safety

We have recently purchased a business in Queensland that stores more than 10,000kg of hazardous chemicals. What are the requirements for storing this amount of hazardous chemicals?

Your workplace may be either a manifest quantity workplace or a major hazard facility depending on the hazardous chemicals you are dealing with.

For a manifest quantity workplace, Schedule 11 of the Work Health and Safety Regulation 2011 (Qld) (Regulation) lists the manifest quantities of hazardous chemicals. Section 347 of the Regulation provides that, if a quantity of a schedule 11 hazardous chemical stored at the workplace exceeds the manifest quantity, a person conducting a business or undertaking (PCBU) must:

  • prepare a manifest of schedule 11 hazardous chemicals; and
  • amend the manifest as soon as practicable if the type or quantity of schedule 11 hazardous chemical that must be listed in the manifest changes or there is a significant change in the information required to be recorded in the manifest.

A PCBU must keep the manifest in a place determined in agreement with the primary emergency service organisation, available for inspection under the Work Health and Safety Act 2011 (Qld), and readily accessible to the emergency service organisation.

Also, a PCBU must ensure that the regulator (Work Health and Safety Queensland) is given written notice if a quantity of a schedule 11 hazardous chemical that exceeds the manifest quantity is stored at the workplace (section 348).

You may be a major hazard facility if schedule 15 chemicals are present or likely to be present in a quantity that exceeds their threshold, or if determined by the regulator to be a major hazard facility.

A major hazard facility must be licensed (section 535) and the operator of a major hazard facility must notify the regulator of this circumstance (section 536).
