The fatal accident frequency rate is declining over the reporting period, but there is an increasing trend in the area of serious injury. Cookers, recreational equipment and hot water systems were found to be most commonly involved in incidents resulting in serious injury. Trends for minor injuries show a decreasing rate over the reporting period.

Analysis of gas utilisation incidents shows that the majority of incidents occur in a non- workplace environment, with natural gas being the primary gas source. The most common types of equipment found in utilisation incidents are water heaters (hot water systems), followed by LPG (storage) cylinders and recreational equipment. Component failure and lack of maintenance were the common causes of most utilisation incidents indicating that more information or education in this area may be necessary to prevent such incidents.

Over the reporting period there were not many incidents related to auto gas or butane. However, lunch box cookers with butane canisters pose a safety risk. This was evident where an incident resulted in four people being seriously injured.

Gas supply incidents show the inverse of utilisation with the majority occurring in a workplace environment. Gas workers accounted for just 5% of these incidents and workers from other occupations accounted for approximately 75% of these incidents. The majority of these incidents are the result of third party strikes or damage to the network by people not residing at the premises nor the owner of the network. Most gas supply incidents resulted from damaged piping due to excavations or people digging and inadvertently hitting a gas pipe. Overall, supply incidents have a higher safety outcome compared to utilisation.
