National payment system(NPS) - is an association of financial transfer operators Money inside Russia. NPS is an alternative to the well-known Visa and MasterCard.
Attempts to create an NPS in Russia were made back in the early 1990s, but this idea was taken seriously only in the 2000s. The Federal Law "On the National Payment System" was adopted in 2011. Federal Law as amendeddescribed NPS as the entire set of money transfer operators, defined basic concepts, regulated the procedure for providing payment services, and so on. However, it did not provide for the creation of a national payment card system.The law acquired its final form and force afterSigned on May 5, 2014 the federal law on the creation of a national payment card system (NSCP).

Why was the NPC needed?
The reason for the creation of the NPS was a difficult situation, which occurred on March 21, 2014 and was provoked by sanctions against Russia. On this day payment Visa systems and MasterCard blocked plastic cards a number of Russian banks whose owners were subject to US sanctions. Then operations on the cards of Rossiya Bank, Bank, SMP Bank and Investkapitalbank were stopped.
Later, Visa and MasterCard still unblocked the cards, but in order to prevent such incidents, they took up the issue of putting the Russian payment system into operation closely. In addition, from now on, Russian banks are already carrying out intra-Russian operations on MasterCard cards through National system payment cards (NSCP).
The official message from the Central Bank states:
The first five banks, including regional ones, began from January 30, 2015 to process part of domestic transactions on MasterCard cards through the NSPK processing center with settlements for these transactions through.
Bank Rossiya, as well as Alfa Bank, UBRD and Gazprombank began working in test NPS mode.
According to experts, the final transition to a unified national payment system will not be noticeable for the average user. The card holder will be able to do everything as before financial operations within Russia using cards he already has.
However, in the long term, the project involves the creation of a full-fledged system, with the replacement of cards, re-equipment of ATMs, and so on. But the financiers themselves do not yet know what the final version will look like.
One thing remains obvious: once the NPS is fully operational, anyone will still be able to use the capabilities of Visa, MasterCard and other foreign operators.

Fire-fighting equipment should be stored in locations specified in the layout and periodically inspected to ensure it is ready for immediate use. Working with faulty fire extinguishing equipment is not permitted.
It is necessary to constantly monitor pipelines and equipment for leaks in connections. All leaks in connections must be eliminated. All noticed malfunctions are recorded in the logbook. Any repair work on operating equipment is prohibited!
If it is necessary to carry out work on site, where possibleO formation of a flammable mixture of vapors and air, in order to avoid And To avoid sparking from impacts, the use of hand tools that cause sparking is prohibited.
All work in existing pumping stations is carried out only withwhat new supply-in s heavy ventilation.
Operating personnel should remember that when workingV Shoes lined with iron nails or with metal heels are not allowed in fire hazardous areas.
The oil pumping rooms are equipped with telephone communications and sound alarms to alert operating personnel.
Oiled or oil-impregnated cleaning material is collected in special metal boxes with tight-fitting lids and removed at the end of the shift.
Doors on escape routes open freely in the direction of exit from the building.
The NPS territory has a sound warning system in case of an accident or fire.
All PS buildings and structures, fire reservoirs, hydrants, as well as approaches to firefighting equipment and supplies must be provided with free access.
In winter, roads, driveways, entrances, and fire hydrants must be cleared of snow and ice, and hydrants and fire reservoirs must be insulated.
Automatic protection means located on switchboardsTO I&A have inscriptions defining their purpose, and the permissible parameters are clearly marked on the instrument scales.
The pressure gauges are installed so that their readings are clearly visible to operating personnel, while their scales are located vertically or tilted forward up to 30° to improve the visibility of the readings.
With remote and local control, pumping station equipment is taken out of operation or standby after permission and registration from the dispatcher, except in cases of obvious danger to people, as well as in cases of emergency.
All types of oil pumping station structures are protected from direct lightning strikes, its secondary manifestations and from static electricity arising during the movement of oil, while grounding devices for protection against static electricity are combined with grounding devices for electrical equipment.
To protect operating personnel from electric shock due to insulation breakdown, protection from dangerous sparking, static electricity and the dangerous effects of lightning, a complex protective device is installed on the pump station, consisting of neutral protective conductors, equalizing conductors and grounding conductors and grounding conductors.
All conductive parts, third-party conductive parts, solidly grounded neutral points of transformers and generators on side 0.4To B, as well as lightning rods To and must be connected to the KZU with a metal connection.
Stay on NP From persons who are not directly related w Any interference with its maintenance is prohibited.
7.3. Safety measures when stopping pumping equipment
When stopping pumping equipment, the following safety requirements must be observed:
- stopping the pump for repairs and disassembling it must be done with the permission of the station manager or the person replacing him and in accordance with current instructions;
- upon completion of pumping, the valves at the pump intake and discharge must be closed.
Atswitchingpumps from working to standby and vice versa, the following safety requirements must be observed:
- when switching from an operating pump to a standby one, the correct opening of the corresponding valves and the readiness of the pump for start-up must be checked;
- If it is necessary to repair a pump that is in reserve, the electric motor drive must be de-energized, and a sign “Do not turn on - people are working” should be posted on the electric motor starting device. The sign can be removed only with the permission of the pump station dispatcher or the person replacing him. It is prohibited to operate the unit with a warning sign posted;
- repair of a hot pump put into reserve should begin only after its housing temperature does not exceed 45 °C;
- standby pumps must be constantly in such a state that they are ready to start as soon as possible after stopping the working pump.
All of the above operations for starting, operating and stopping pumps should be carried out taking into account the requirements of the manufacturer's instructions for operating specific equipment.
