Number of WA gas related incidents per million population

There were 32 incidents per million people, of these 12 incidents per million resulted in some form of injury.
 
All the incidents recorded can be broadly classified into gas utilisation and supply incidents. 74% of all incidents in the reported period were related to gas utilisation. The high number of reported gas utilisation incidents may be due to the legislative requirement to report gas incidents.

For supply incidents, there is a requirement to report incidents which have a major discharge of gas. Figure 3 below provides information on the number of incidents reported to EnergySafety each year.
