Protection zone for a gas installation
In order for those operating in the protection zone for a gas installation to be aware of the existence, location and danger of the gas installation, Elering has marked all of its gas installations. To this end, appropriate signposts with the warning sign “Explosion hazard” are installed on the gas route to mark the underground gas pipeline. It is prohibited to destroy, damage or arbitrarily relocate gas installation signs.
Protection zone for a gas route
Warning sign for gas hazard
In the protection zone for a gas installation, it is prohibited without the permission of the owner of the installation to:
- make fire;
- grow trees;
- in the case of a gas installation located in a body of water, dredging work, anchoring a watercraft, moving with a dropped anchor, chains, logs, trawls and nets.
Always obtain Elering’s prior approval for any planned activities in the protection zone!
Protection zone for a gas pipeline
Considering the nominal diameter of the pipeline, the protection zone for a gas pipeline on both sides from the centre of the pipeline is:
- with nominal diameter of <200 mm – 3 meters;
- with a nominal diameter of ≥200 mm and <500 mm – 5 meters;
- with a nominal diameter of ≥500 mm – 10 meters.
Protection zone for underwater gas pipeline
When installing a gas pipeline underwater, the extent of the protection zone is twice as wide as the specified extent of the protection zone, i.e., taking into account the nominal diameter of the pipeline, the protection zone for a gas pipeline on both sides from the centre of the pipeline is:
- with nominal diameter of <200 mm – 6 meters;
- with a nominal diameter of ≥200 mm and <500 mm – 10 meters;
- with a nominal diameter of ≥500 mm – 20 meters.
Protection zone for gas stations
The protection zone around gas stations (regulating and distribution stations, metering stations, gas compressor stations) extends 10 metres from the fence, wall of the building or, in their absence, from the equipment.
