Gas supply systems and gas pressure standards. Gas supply systems and gas pressure standards Rules for technical operation and occupational safety requirements in the gas industry of the Russian Federation

The health and life of people and the safety of their property directly depend on strict adherence to certain safety rules in gas management. Similar requirements are specified in special regulatory documents. This is direct responsibility for the long-term use of equipment and for maintaining all utilities in working order.

Basic requirements for gas operation

Modern safety rules in a certain way provide for certain responsibilities regarding the use of gas in everyday life. Here you can note such points as:

1. Completing training on the safe use of gas in organizations that are responsible for operating such a facility, as well as strict adherence to basic instructions for the use of gas equipment.
2. If necessary, you need to call an employee of the gas utility company. This is necessary to make certain changes to the taps of such engineering communications, during their operation, if some malfunctions are detected in the equipment used. At the same time, access to specialists must be ensured at any time. To ensure your own safety, it is necessary to check the presence of an official ID.
3. It is important to observe the most economical use of gas, as well as make timely payments. There is a requirement for competent and careful use of devices and for timely maintenance.
4. It is required to periodically check the head in winter time, thoroughly clean it of ice and frost.
5. Security in the building is required high-quality ventilation, in particular the installation of chimneys.
6. If breakdowns are discovered during thorough inspections, it is necessary to immediately organize repairs of gas equipment.

There are also some requirements that apply to construction companies. Moving into gasified apartments and houses is allowed only if you have all the necessary documentation, which will confirm that the owner of the apartment has undergone certain safety training, as well as whether the property complies with all safety requirements.

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 General rules industrial safety for organizations involved in the field of industrial safety, approved by the predecessor of Rostechnadzor - 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 at industrial enterprises and agricultural production facilities;
• CHP equipment, gas preparation, purification and drying stations;
• internal and external systems of district heating stations, as well as boiler houses various types, both built-in and placed 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 automatic control 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 to 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.

Where to find PB 12 529 03

In system "Technical expert: Industrial safety" You will find the text of the inactive PB 12 529 03 with the latest changes, comparative analysis PB 529 03 and new federal rules. Users of the system have access to original materials on topics such as:

• legislative initiatives in the field of industrial safety during the operation of gas networks;
• causes of emergencies at gas supply facilities.
