Major hazard facilities
Australian Government agencies and statutory authorities, and self-insured licensees, must follow requirements for major hazard facilities. This includes notification and licensing.
Major hazard facilities explained
Major hazard facilities are sites that store, handle and process large quantities of hazardous chemicals and dangerous goods. This includes explosives that exceed allowed limits.
Common examples of major hazard facilities
- Chemical manufacturing and storage
- Explosive storage depots
- Explosive and munitions manufacturing facilities
- Gas processing plants
- LPG storage and distribution facilities
- Some warehouses and transport depots
- Fuel storage depots.
How we manage risks at facilities
The key risks at major hazard facilities are explosion, fire, and the release of chemicals in the facility or surrounding area.
We help manage these risks through:
- mandatory licensing of major hazard facilities
- requiring facilities to notify Comcare when they have more than a specific quantity of chemicals.
For more information, see:
Notification and threshold quantities
Each hazardous chemical has a notification and threshold quantity.
- At the notification quantity, a facility must notify Comcare.
- At the threshold quantity, a facility must apply for a major hazard facility licence.
- Between the notification and threshold quantity, Comcare may determine that the facility requires a major hazard facility licence.
Quantities of common hazardous chemicals
Table 1 provides the quantities for some common hazardous chemicals.
A full list of the notification and threshold quantities for hazardous chemicals is available in schedule 15 of the Work Health and Safety Regulations 2011.
|Hazardous chemical||Threshold quantity|| Notification quantity|
(When to notify Comcare)
5,000 tonnes or more
250 tonnes or more
2 tonnes or more
20 tonnes or more
2.5 tonnes or more
Notification of chemical quantities
Meeting your obligations to notify
The Major Hazard Facilities Notifications and Determinations guide provides information to help operators of facilities meet their obligations. This includes operators who are, or are likely to become, a major hazard facility.
This guide assists operators to:
- provide prompt notification for an existing facility
- provide timely notification for a new or proposed facility
- accurately calculate the quantity of schedule 15 chemicals present or likely to be present at the facility
- supply all the information required in a notification.
When you need to notify
You must notify Comcare when your facility reaches or exceeds the notification quantity for any of the chemicals listed in schedule 15 of the Work Health and Safety Regulations 2011.
How to notify
Submit the Major Hazard Facility Notification form (PDF, 83.7 KB) to notify Comcare if your facility controls schedule 15 materials greater than the 10 per cent threshold quantity.
The form includes more information about the process.

Major hazard facility licence
When you need to apply for a licence
A major hazard facility licence is required when a facility has chemicals listed in schedule 15 of the Work Health and Safety Regulations 2011 present, or likely to be present, and:
- the quantity exceeds the threshold quantity, or
- the quantity is between the notification and threshold quantity and Comcare has determined that the facility is a major hazard facility and requires a licence.
When we determine if a facility is a major hazard facility, we consider:
- the amount and combination of schedule 15 chemicals
- the type of activities at the facility
- land use and other activities in the surrounding area.
How to apply for a licence
Operators of a major hazard facility must apply to Comcare for a licence to operate the facility.
Submit the Operate a Major Hazard Facility application form (PDF, 175.2 KB) to apply for a licence to store, handle or process large chemicals in a major hazard facility.
The form contains more information about the application process.
Develop a safety case and have it assessed
In the licence application, you must develop a safety case for the facility and have this assessed by an approved assessor.
The assessor must prepare an assessment of the safety case for the major hazard facility together with an executive summary.
The major hazard facility operator then submits the executive summary to Comcare in support of the licence application.
