Hazardous materials emergency incidents: public health considerations and implications

Objective: Hazardous materials (HAZMAT) incidents, including the deliberate release of toxic chemicals, can cause a significant drain on resources as well as heightened anxiety in the community. Recent high‐profile incidents, including the 2018 illegal waste storage fire in Victoria, Australia, have highlighted the complexity but also the value of multidisciplinary approaches to HAZMAT events. This brief report examines issues from a public health perspective and reflects on the experience of such events in South Australia. Methods: The type, location and time of HAZMAT incidents for the period 2001 to 2018 (inclusive) in South Australia were compiled and classified from a database of the state Technical Advice Coordinator. Results: The profile of HAZMAT events was diverse, including fires, spills, unknown chemicals, sabotage and suicides. Incidents frequently occurred around transportation corridors and storage facilities. Public health agency involvement was most evident for known or suspected biological agents (toxins) and chemical toxicants with persistent exposures. Conclusion and implications for public health: Public health agencies are likely to have a greater future role in HAZMAT management as the complexity of incidents increases (e.g. mass casualty events and events involving vulnerable subpopulations). There is a need for a national HAZMAT surveillance database to coordinate agency responses on a national level. A unified approach to risk communication for vulnerable communities is also critical.
