Safe Operation

1. General safety requirements

1.1. Persons at least 18 years of age, trained and certified in the prescribed manner, who have passed a medical examination and briefing at the workplace, who have a certificate with a photograph for the right to perform this type of work, who have passed a knowledge test on safety rules in the gas industry, are allowed to drain liquefied gas into group installations .

1.2. Personnel must comply with the internal labor regulations, fire safety rules and this manual.

1.3. Persons admitted to draining liquefied gas into group installations must know the Rules for the Design and Safe Operation of Pressure Vessels and the Safety Rules in the Gas Industry in regard to the transportation, storage and use of cylinders filled with gas under production conditions.

1.4. Workers performing work on draining liquefied gas in their work must use the following personal protective equipment:

cotton robe;
combined gloves.

1.5. At the same time, overalls and other PPE must be clean and free of oil stains.

1.6. Persons responsible for the storage, receipt from the warehouse and transportation of compressed gases are appointed by order of the head of the organization.

2. Safety requirements before starting work

2.1. Put on the appropriate overalls, safety shoes.

2.2. Inspect the workplace, free it from foreign, combustible materials.

2.3. Prepare the necessary tools, fixtures, gaskets.

3. Safety requirements during work

3.1. The truck tank must be grounded when draining.

3.2. When draining liquefied gas from road tanks, both emptying and filling tanks must be constantly monitored.

3.3. Removing the plugs from the drain fittings of the tank is allowed after the engine is stopped, and the engine is turned on only after the sleeves are disconnected and the plugs are installed.

3.4. The value of the maximum filling of the tank with liquefied gas at a temperature of plus 10°C and above should not exceed 85% of the geometric capacity.

3.5. In case of overfilling of the tank, excess gas in excess of the established rate must be drained. Excess gas must be released into special containers slowly so that a dangerous concentration of gas is not created.

3.6. Draining gas from a tank truck into a group installation is carried out in the following sequence:

turn off the engine of the tanker, ground it;
connect the hose at one end to the gas phase valve of the tank truck, and the other end to the gas phase valve of the group installation;
connect the liquid phase hose with one end to the tank drain valve and the other end to the group unit's executive valve.
open the gas phase valve from the group unit and the drain valve on the tank truck and observe the gas discharge;
gas discharge can occur due to the difference in liquid levels in the tank and the tank, if the tanker is equipped with a pump - forcibly;
in summer, when the gas pressure in the tanker is much higher than in group installations, it is not necessary to connect a vapor phase hose.

3.7. After the group installation is filled with liquefied gas to the established norm, it is necessary:

close the drain valve on the tank truck;
lifting the filling hose, drain the remaining gas from it into a container and close the filling valve on it;
open the valve of the bypass line and discharge the remaining gas from the hose into the gas network, close the valve on the bypass line;
close the gas phase valves on the tank truck and the group plant;
carefully disconnect the hose from the tank and the tanker, releasing the constantly remaining vapors of liquefied gas;
after disconnecting the hoses, the valve fittings must be plugged with special plugs and tested for density with a soapy emulsion.

3.8. Safety covers of group installation must be locked and sealed.

3.9. During the discharge of liquefied gas, there should be no unauthorized persons on the territory of the group cylinder installation so that there is no open fire within a radius of 15 m.

3.10. Control over the operation of a group installation is carried out by persons determined by the order for the enterprise on whose balance sheet the group installation is located, trained in safety rules in the gas industry and passed a knowledge test in a commission with the participation of an inspector.

4. Safety requirements in emergency situations

4.1. When receiving a thermal burn, if the victim's clothes caught fire. You need to quickly throw any dense fabric on it or bring down the flame with water.

4.2. In case of small-sized burns of the 1st and 2nd degree, a sterile bandage should be applied to the burnt area of the skin and the victim should be sent to a medical institution. Notify the work manager. In case of severe and extensive burns, the victim must be wrapped in a clean cloth or sheet without undressing him, covered warmer, and calm until the doctors arrive.

5. Safety requirements upon completion of work

5.1. After completion of work, carefully check the condition of the workplace.

5.2. Wash your hands with soap and take a shower.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The dangers of 5G communications for the health of bees 30.05.2019

Currently, insects are on the verge of extinction due to the use of various pesticides by farmers and advances in technology. However, according to experts, the real situation can worsen at times: insects are unlikely to survive the new generation of mobile communications. A real miracle will happen if they do survive.

Experts have been talking about the disappearance of bees for a long time. They are negatively affected by 2G, 3G, 4G, and soon the list will be replenished with 5G. The new communication standard will be a ticking time bomb. Researchers from the Swiss organization "Pro Natur" found that radiation affects the antennae of insects, raising the temperature of the entire body. Maybe in the near future there will be no bees and invertebrate arthropods at all. This will result in a real collapse of civilizations.

The new generation of communications will operate at 120 GHz, while existing standards operate at 6 GHz. Frequencies above 10 GHz are used by insects. Therefore, 5G has the potential to change the physiology and behavior of arthropods.

Scientists call on the authorities of the countries where the launch of the technology is planned to present operators with increased requirements for environmental control. Otherwise, the world will starve.
