Though the numbers of major incidents have been low, there are each year a number of gas releases which occur as a result of mains failures.

There are potential hazards from these gas mains failures and HSE is working with Industry to mitigate the risks from these and major pipeline incidents

HSE is responsible for ensuring that those involved with the transmission, distribution and storage of natural gas comply with the relevant legislation.

HSE has employed a rolling operational strategy to identify major gas safety issues and, where possible, improve existing standards. The main current key programme is the mains replacement programme.
