On 17 September 2023, at a chemical processing plant in North West Queensland, a release of pressurised hydrogen gas resulted in an explosion and fire injuring three workers and causing damage to plant. The incident occurred during the recommissioning of equipment after routine scheduled maintenance.
The injured workers included two workers who were completing the recommissioning and a store worker who was approximately 40 m from the location of the incident. The injured workers did not require hospitalisation; however, the event had the potential to cause a more significant adverse effect.
