Other substance (HAZMAT)



Radiologic​al substance

​Intermittently, global events see renewed interest in the potential use of radiological material, including their deliberate use on the civil population. Public health and safety experts continue to ensure the state is safeguarded from CBR risks.

Radiatio​n​: Nuclear powered warship

​Response plans are in place to manage the hazards presented when nuclear warships traverse Western Australian waters. It is possible that human error, equipment failure or misdeed may create a radiation escape within the state’s jurisdiction. Arrangements are in place to limit the consequences.​

Rail ​​​crash 


​Western Australia has more than 5000 km of freight rail network. Despite ongoing maintenance, it is not possible to eliminate the risk of derailment, collision, malicious act or other rail incidents on the network. Such an event could significantly disrupt the flow of vital services. ​

On a typic​​al weekday, more than 1000 passenger train services operate within Western Australia, with additional trains servicing regional centres. A derailment or collision on such a service could result in a mass casualty incident requiring substantial resources and coordination.​

Road cra​sh​

​Vehicl​e accidents occur daily. Planning and contingencies are in place should such an accident be of sufficient size or impact to overwhelm local resources or require significant coordination of multi-agency resources.​

Spac​​e re-entry​ debris​

Space debris has been descending out of orbit at an average rate of about one object per day for the past 50 years [1]. In 1979 debris from Skylab landed south-east of Perth and was found between Esperance and Rawlinna.

Storm

​Storms can occur almost anywhere in Western Australia and at any time of the year. They routinely cause damage to dwellings and structures, sometimes as an isolated event and at other times causing widespread or severe damage. Due to the frequency, unpredictability and widespread geographical areas involved, storm is a major hazard for Western Australia​.

​​Terr​orism​

A number ​​of terror organisations and terror cells have been identified as operating in Australia. Their activities have varied from fundraising and providing material support for terror activities overseas, to plotting and undertaking domestic terrorism. The emergence of Islamic state has raised concerns globally.

Tsunami

Earth​​quakes happen regularly near the volatile volcanic region around the south coast of Indonesia and have at times caused tsunamis that have inundated parts of the Western Australian coast. The geological instability of this area, along with other potential causes of tsunamis, means that tsunamis remain an ongoing hazard.
