On the application of the Safety Rules for Gas Distribution and Gas Consumption Systems (PB 12-529-03)
PB 529 12 03 - a set of safety rules that must be observed during the operation of gas distribution and gas consumption systems, was in force for 10 years and was canceled in November 2013 by order of Rostechnadzor. Thus, as of today, PB 12 529 03, which came into force on March 18. 2003, have the status of an inactive document.
For what purpose did they approve PB 529 12 03
PB 12 529 regulated all stages of work with gas distribution networks: from the development of design documentation, construction of systems, their installation, maintenance, debugging to reconstruction and overhaul. Along with PB 12, the rules for working with gas networks are enshrined in the General Industrial Safety Rules for organizations involved in the field of industrial safety, approved by Rostechnadzor’s predecessor, Gosgortekhnadzor, in November 2002.
The PB for gas supply applied to gas pipeline facilities located:
- in settlements and inter-settlement areas;
- external and internal systems installed in industrial enterprises and agricultural production;
- CHP equipment, gas preparation, purification and drying stations;
- internal and external systems of district heating stations, as well as boiler houses of various types, both built-in and located on the roof;
- gas control points, gas distribution stations, cabinet points, gas control units;
PB 529 12 03 replaced the federal standards of Rostechnadzor
Safety rules in the gas industry (PB 12 529 03) also applied to means of protecting gas pipeline systems from corrosion, to means of automatic control of the supply and distribution of raw materials, as well as to buildings located on gas pipeline networks. PB 12 529 03 did not apply to gas pipelines and equipment installed at metallurgical enterprises, as well as at automobile compressor stations.
Having lost force according to the order of Rostekhnadzor, the safety regulations for gas distribution and gas consumption were replaced by federal rules for the safety of gas distribution and gas consumption networks. Federal regulations, which became the successor to PB 529, came into force on July 28. 2014. New safety rules for gas distribution and gas consumption systems left in the past an entire section containing technical requirements for boiler houses: industrial and heating. The updated version of the rules, unlike PB 12 529 03, does not contain a block with gas distribution terminology, as well as certification requirements for employees and managers.

Safety rules for gas distribution and gas consumption systems pb 12-529-03
Safety rules for gas distribution and gas consumption systems regulate industrial safety requirements in the field of gas distribution and gas consumption of natural hydrocarbon gas (methane).
These Rules, developed for the first time, take into account the provisions of the existing legislation of the Russian Federation in the field of industrial safety, as well as the requirements of current regulatory legal acts.
1. General provisions Basic terms and definitions
For the purposes of these Rules, the following terms and definitions are used.

On-site gas pipeline- a section of the gas distribution pipeline (input) that provides gas supply to the industrial consumer, located inside the production territory of the enterprise.
Product (technical device)- a unit of industrial product for which the documentation must comply with the requirements of state standards ESKD, ESTD and ESPD, which establish the completeness and rules for the preparation of accompanying documentation. The requirements of building codes and regulations do not apply to the design of the product and accompanying documentation.
Design pressure- the maximum excess pressure in the gas pipeline, for which strength calculations are made when justifying the main dimensions, ensuring reliable operation during the design life.
Estimated service life- the total operating time of an object from the start of its operation or resumption after repair until the transition to the limit state.
Estimated service life- calendar duration from the start of operation or resumption after repair until the transition to the limit state.
Connecting parts (fittings)- elements of a gas pipeline intended to change its direction, connections, branches, and connections of sections.
Diagnostics- a field of knowledge covering the theory, methods and means of determining the technical condition of objects (gas pipelines and structures).
Maintenance- a set of operations or an operation to maintain the functionality or serviceability of a product (technical device) when used for its intended purpose, waiting, storage and transportation.
Repair- a set of operations to restore the serviceability or performance of products (gas pipelines and structures) and restore the resources of products or their components.
Gas control point (GRP), installation (GRU)- a technological device designed to reduce gas pressure and maintain it at specified levels in gas distribution networks.
Cabinet gas control unit (GRP)- a technological device in a cabinet design, designed to reduce gas pressure and maintain it at specified levels in gas distribution networks.
Block gas control point- a fully factory-ready technological device in a transportable block design, designed to reduce gas pressure and maintain it at specified levels in gas distribution networks.
Gas hazardous work- work performed in a gas-filled environment or in which gas may escape.
Hot work- work involving the use of open fire.
Dangerous concentration of gas- concentration (volume fraction of gas) in the air exceeding 20% of the lower control limit of flame propagation.
Unbrakable control- determination of the characteristics of materials without destroying products or removing samples.
Certification of welding (soldering) technology- a procedure for determining the indicators and characteristics of welded (brazed) joints of pipes and connecting parts, carried out to confirm the technical and organizational capabilities of the organization to carry out welded (brazed) joints using the certified technology that meet the requirements of regulatory and technical documentation.
