Gas leaks may occur in the form of seepage of natural gas from pipelines or stations. Natural gas is nontoxic and, being lighter than air, it rises into the air. But leaking natural gas is flammable. If a fire is lit, or there is a spark near the seeping gas, the result could be a fire.
If there is a gas leak at one of our installations, the gas will be detected by the many gas detectors installed. The systems will then shut down in fail-safe condition.
The Danish gas transmission network is monitored 24/7 from our control centre in Egtved, and there are always many employees on call to respond to the faults and alarms that may occur at our installations.
Gas leaks are extremely rare. Since the 860 km long transmission network was built in the 1980s, only one incident has been reported. This was a very small gas leak that did not have any serious consequences. But Energinet.dk is prepared for all contingencies, having prepared a long line of contingency plans in collaboration with the police and the fire de-partment. These plans are tested on a regular basis.
Our emergency preparedness exercises may occasionally give rise to various kinds of in-convenience, for example in the form of noise. But we ask our neighbours to be under-standing, also when our exercises take place at night.
