Safety at gas receiving station
As a connected party and owner of the connection building, you are responsible for safety. The safety regulations in the European Directive on safety in potentially explosive atmospheres (ATEX) apply to the installation in the gas receiving station as well as the space in which the installation is installed.
In the interests of safe working practices, you should always inform Gasunie of works within the zone. You can contact our operational work preparation personnel for that. For the telephone numbers, see “Safety Contact”.
Classification of the building and consequences for electrical equipment
The safety classification for indoor spaces and the associated standards depends on the ventilation factor of these spaces (the number of times per hour that the content of the space is ventilated). Almost all gas receiving stations are ventilated less than five times per hour. Consequently the gas pressure regulation space is classified as zone 1. The space within a one metre radius of the ventilation openings and door openings on the outside of the gas pressure regulation space also comes within zone 1.
Gasunie has produced drawings of the zones at the station, on which gas pressure regulation space and the outside up to one metre away are classified as zone 1. This has consequences for the equipment used in this zone. Gasunie ensures that its installation complies with these regulations. It is your responsibility to ensure that the part of the installation that you own complies with the regulations.
Gasunie has the complete electrical installation at the station tested once every 8 years. Gasunie will inform you of any defects in your installation and will ask you to rectify them.
You must be able to demonstrate that the installation has been designed, manufactured and inspected in accordance with the applicable legislation and regulations. You must be able to demonstrate that the installation has been maintained and inspected in accordance with the applicable legislation and regulations throughout its use.
New gas pipelines
Gas pipelines designed for a pressure of >500mbar must be constructed in accordance with the Pressure Equipment Directive (see http://www.rijksoverheid.nl/ministeries/szw ). Under this Directive, the design of a gas pipeline must be checked by an organisation designated by the Ministry of Social Affairs and Employment (Notified Body, NoBo for short). Go to http://www.rijksoverheid.nl/ministeries/szwl and search for - Warenwetbesluit drukapparatuur -. An EU Declaration of Conformity for the product or combination of products must be drawn up by the manufacturer or assembler as specified in the Pressure Equipment Directive.
Existing gas pipelines
The gas pipelines must be subjected to a proper quality system. NEN 2078, annex K can be used for this. By 2011 the NEN 2078 was expired and succeeded by the EN 15001-1 and EN 15001-2 (Detailed functional requirements for commissioning, operation and maintenance).
New standard gas appliances
Under the Gas Appliance Directive (GAD), new standard gas appliances, such as central heating boilers and hot air heating, are required to have a CE mark. For standard appliances, which have a CE mark, the installer must produce a report stating that the appliance has been set according to the manufacturer's settings. For standard appliances, or assemblies (cascade connections) being one combustion installation with a nominal capacity of >100 KW, which have a CE mark, a certified body must draw up a report stating that the appliance has been set according to the manufacturer's settings. The commissioning certificate must be in conformity with SCIOS (certification, inspection and maintenance body for combustion installations). For more information see: www.scios.nl.
New special gas appliances
For these appliances a complete manufacturing file must be prepared by the manufacturer and assessed by a certified body. The commissioning certificate must be in conformity with SCIOS. For more information see: www.scios.nl. The manufacturer or assembler of these appliances draws up an EU Certificate of Conformity.
Maintenance of existing appliances
Existing appliances should be maintained and inspected at the intervals specified by the manufacturer. Maintenance can also be carried out according to the SCIOS guideline. More information and a list of SCIOS-certified inspection and maintenance companies can be found on the organisation's website www.scios.nl.
Inspection of existing appliances and pipelines
Existing appliances and pipelines must be maintained and inspected at the intervals indicated by the manufacturer.
The Decree on Emission Regulation Mid-sized Combustion Plants [BEMS] expired on 01-01-2013 and was replaced by the "2013 ACTIVITIES DECREE".
What changes have been made with regard to combustion plants in the 2013 ACTIVITIES DECREE:
The term ‘combustion plant’ is now the same as in the Industrial Emissions Directive (Combustion plant: any technical apparatus in which fuels are oxidised in order to use the heat thus generated).
As a result, the following combustion plants are now also covered by the scope of the Activities decree:
- Plants in which the combustion gases are used solely to dry or treat products, such as brickworks, bakers’ ovens, cement ovens, plant used for roasting ores, drying hay and green fodder, asphalt mixing plants, pelletising plants, glass furnaces and so on.
- Combustion plants in which the heat is transferred to thermal oil, with the thermal oil acting as a medium for heat transport.
- Process ovens: combustion plants used primarily for purposes other than heating water or steam.
- Space heaters, used for heating (rooms).
- A new definition of ‘boiler plant’ has been added: combustion plant, consisting of a boiler in which fuel is burned primarily in order to generate power or transfer heat to water, steam or a combination of water and steam.
- Newly installed gas-fired boiler plants with a capacity of 400 kW or more must undergo an NOx test must take place within four weeks of commissioning. This requirement applies to all combustion plants with a capacity of 400 kW or more from 1 January 2017.
- The new Activity Regulations (art. 3.7 m) state that the test must be carried out by a firm holding a valid certificate issued by a body which is accredited by an accreditation body in accordance with the “Assessment Guidelines for the Performance of Maintenance and Inspections of Combustion Plants” which form part of the ‘Rules on the Certification of Inspection and Maintenance of Combustion Plants’ drawn up by the Netherlands Foundation for the Certification of Inspection and Maintenance of Boiler Plants (SCIOS).
In other words: the firm performing the test must have an SCIOS certificate for the plant which is to be tested. Equivalence has been abolished.
In addition, the emission requirements for combustion appliances using gaseous, liquid and solid fuel have been tightened and extended.
Foreign firms wishing to conduct inspections in areas covered by SCIOS can apply to the Accreditation Council for equivalence.

Pay particular attention to points 6 and 7 which are essential, which was not the case in the BEMS.
For information about maintenance and inspection of fuel pipelines, read the section headed What relevant legislation is there in this area.
If the gas equipment link is temporarily decommissioned at the request of the connected party for alteration, adjustment or repair of the gas equipment behind the gas transfer point, this alteration or repair must comply with the relevant legislation and regulations. This adjustment or repair must be carried out in a demonstrably integral manner. Integrity is demonstrated via a notified body under the terms of the Commodities Act Decree on Pressure Equipment or the user's inspection department.

After the transfer point, cathodic protection is your responsibility.
Control measurements must be taken in accordance with EN 12954. The frequency of the measurements depends on a number of different factors but annual measurements generally suffice.
A limited stream from the Gasunie network continues to be available.
The Gasunie cathodic protection posts behind the transfer point are removed.
