In the production of gas hazardous work, in addition to the requirements set forth in this instruction, the requirements of the "Instruction on the general rules of labor protection and fire safety", as well as the requirements of other instructions for professions and types of work, depending on the nature of the work performed, must be met.

1.3. Gas hazardous work includes work carried out under the following conditions:

in the presence or possibility of release into the air of the working area of toxic, explosive and flammable substances in quantities that can cause poisoning of people, explosion or fire;
when the oxygen content in the air is less than 20% by volume.

1.4. The greatest probability of accumulation of explosive gases and vapors of petroleum products is possible in the following places:

pumping stations for pumping oil products;
reservoirs for storage of oil products and the territory immediately adjacent to them;
loading and unloading racks, berthing facilities, especially at the time of unloading and loading of oil products;
isolated and non-ventilated premises where equipment is located or where oil product or gas pipelines pass, as well as in similar premises without equipment and communications;
technological pits and wells;
trays with process pipelines, industrial sewage wells.

The accumulation of explosive gases and vapors of petroleum products is also possible under the following circumstances:

leakage of oil products and penetration of their vapors through leaks in hatches, covers, seals;
malfunctions of shut-off, control, safety valves and other oil product pipeline equipment;
carrying out drainage of commercial water from tanks;
evaporation of oil products in settling tanks, traps, ponds;
spill of oil products due to violation of the technological regime and for other reasons;
emergency situations.

1.5. The list of gas-hazardous places and gas-hazardous works is approved by the chief engineer of the enterprise, indicating the released toxic and gas-hazardous substances.

1.6. In rooms where the release of flammable gases, as well as vapors of flammable liquids, is possible, the concentration of harmful substances in the air should be determined using gas analyzers.

The places and frequency of air sampling for the analysis of the content of combustible gases and vapors in it must be approved by the chief engineer of the enterprise.

1.7. Appropriate posters and warning signs must be posted in gas hazardous areas.

1.8. Depending on the degree of danger, gas hazardous work is divided into 2 groups:

Group I

1) work related to the depressurization of process equipment and communications, from which toxic, explosive and fire hazardous substances have not been removed or the possibility of their release is not ruled out;

2) work in oil traps, silt pits, settling tanks and other similar places;

3) work carried out in closed containers (inside tanks, boilers, cisterns), pipeline collectors, wells, tunnels, etc.

Group II

1) open drainage of commercial water from tanks, containers, pipelines;

2) sampling, manual measurement of the level in tanks, containers, tanks;

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. ... >>

Methane beer festival 26.12.2019

The contributions of humanity to the formation of a warm blanket of our planet from greenhouse gases, although insignificant, are numerous. And methane, which, in terms of its harmfulness, that is, its heat-holding capacity, gives a twenty-fold head start to carbon dioxide, is one of the most important. This means that the fight against methane emissions is a serious task for climate advocates. And in order to fight seriously, you need to study the enemy well. It would seem that he noted for himself that cows give a hundred million tons of methane per year, became a vegetarian and calmed down in the hope that he had made a feasible contribution to the uncompromising struggle for the cold. But even in this case, you can’t relax, because the enemy has many faces and can lurk in an unexpected place.

Let's take folk festivals. It would seem, where is the emission of methane? But Chen Jia and Florian Dietrich from the Technical University of Munich, with the help of Dutch colleagues and smart devices, got close to the famous Munich beer festival - Oktoberfest. According to them, for 16 days on the central square of Munich, 2018 million people fell to the sources of the foamy drink in 6. They drank 8 million liters of beer, spent 100 million liters of water flushing sewage, 2,9 million kW of electricity and 201 liters of natural gas, of which 79% went to cooking and the rest to heating visitors and vendors.

Before the start of the holiday, methane emission was almost zero, and during the holiday it increased to 6,7 micrograms per second per square meter. Over the weekend, the issue rate doubled, as did the number of visitors. It would seem that this directly indicates that the source of methane is people who excrete it like ruminants. An no. Although methane can be seen in the exhalation of half the people, its amount is small: Oktoberfest attendees could breathe in only 0,13 micrograms of gas per second per square meter of area. The sewage system, although it took 100 million liters of water and 8 million liters of drunk beer, produced negligibly little methane during the holiday - the processing of waste by bacteria requires much more time than 16 days. There remains the spent natural gas, which, in terms of methane, amounted to 134 tons. To ensure the calculated emission, 16 tons had to fly into the atmosphere in 1,47 days, that is, 1,1% is a completely normal estimate for gas leaks.

The conclusion follows from this: it is not beer at the holiday that contributes to global warming, but gas. Abandoning it, say, switching to spirit lamps or gasoline stoves, will significantly improve the situation. True, there was a question for the authors of the work. Usually for portable burners, namely they are used in mobile pavilions, bottled gas is used. And this is not methane at all, but a mixture of propane and butane. If just such a gas was used at Oktoberfest, then the search for a source of festive methane will have to continue.
