3. Safety requirements during work

3.1. Persons who are not related to the operation of the DPP equipment should not be in the DPP premises. They may be admitted accompanied by a person designated by the head of the RRS.

3.2. When stopping the diesel power plant for inspection, cleaning and repair, measures must be taken against erroneous start-up or involuntary movement. The generator connected to the combustion engine must be completely disconnected from all possible extraneous voltages.

3.3. When inspecting and repairing engines, special attention should be paid to the correct tightening and fastening of the nuts of the connecting rod bolts and the correct fastening of the crankshaft. The nuts of the connecting rod bolts must be tightened evenly, without distortion. It is forbidden to put pipes on the wrench or use sledgehammers to hit the wrench. After tightening the nuts of the connecting rod bolts must be cottered. The condition of the pistons, valves and seals of the engine must be such that the possibility of gas penetration into the room is excluded.

3.4. Heavy equipment must be lifted by a permanent or temporary lifting device.

3.5. Service tanks for diesel generator (DG) fuel at RRS are filled from the fuel storage by an electric pump, which is turned on manually or automatically as filling is required. When manually turning on the pump, the service fuel tank must be equipped with a transparent filling level control tube. When the pump is automatically turned on, in order to avoid overfilling the supply tank with fuel, it is necessary to strictly control the operability of the pipeline fuel return overflow valve.

3.6. Manual filling of fuel tank DES should be carried out in daylight or when using lamps of a safe design before the engine starts or after it stops and cools down. Pouring fuel into the tank of a running engine is prohibited.

3.7. Spilled fuels and lubricants on the floor should be wiped up immediately. Cleaning materials should be stored in closed metal boxes, located away from engines, generators, panels and heaters.

4. Safety requirements in emergency situations

4.1. In the event of malfunctions of equipment, tools, injury, the employee is obliged, depending on the specific case, to stop the work performed, notify the head of the RRS about the malfunctions that have arisen, and take measures to eliminate them.

4.2. During the operation of diesel installations, a characteristic malfunction is the jamming of the regulator rail of the high-pressure fuel pump (in a single-plunger pump, jamming of the regulator earring). At the same time, with an increase in the speed of the diesel engine, the fuel supply increases, the speed increases, the process takes on an avalanche-like character (the diesel engine goes into overdrive). For an emergency stop of the engine, it is necessary to shut off the air supply to the cylinders (simply shutting off the fuel supply does not give the desired result, since the recharge continues from the filters and the sump).

4.3. In the event of an accident with a workmate, the employee must be able to provide him with first (pre-medical) aid, call a doctor if necessary.

4.4. In case of injury, inform the management, consult a doctor.

5. Safety requirements at the end of work

5.1. Put the workplace in order, check the availability and compliance of tools, materials, protective equipment, operational documentation and instructions.

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. ... >>

Fullerene balls in the energy sector 08.02.2015

In 1985, chemists first synthesized a soccer ball. It consisted of 60 carbon atoms connected in a three-dimensional geometric figure formed by regular five- and hexagons. This molecule was called fullerene, and for thirty years it has been closely studied in laboratories.

Chemists have learned to do the most virtuoso tricks with a carbon ball - fix various molecules on its surface, put metal atoms inside it, and even showed that solar batteries can be made based on fullerene. In every scientific article devoted to fullerene, scientists stated that it can be used in a wide variety of areas, but the matter never came to a real application. Fullerene remained an amusing toy in the hands of researchers. However, now there is a real chance for the molecular ball to be useful to humanity.

Swedish researchers from Chalmers University of Technology have shown that fullerene can increase the resistance of insulation used to make high-voltage cables. Until the era of wireless electricity has come, the most reliable way to transfer energy over distances is a regular cable. Kilometers of power lines stretch from various power plants to consumers. Most household appliances are powered by 220 volts. Industrial equipment often uses 380 volts. And although both voltages are dangerous and can even be deadly, they belong to the low-voltage class.

The fact is that high voltages - hundreds of thousands of volts - are required to transmit energy over long distances. For example, to transmit electricity from Siberian power plants to industrial enterprises in the Urals, in the 80s of the last century, an ultra-high voltage power line was built - up to 1,1 million volts. High voltage has to be used to reduce losses during the transmission of electricity through wires: the higher the voltage, the less energy is lost along the way from the power plant to the consumer.

There are overhead power lines - these are bare wires hanging on poles and masts. Where it is impossible to use them, cable lines are laid. The cable can be laid underground or underwater. In a cable, a metal wire carrying current is surrounded by a layer of insulator, a non-conductive material. For the production of high-voltage cables, polyethylene insulation is used, the same polymer from which conventional packaging bags are made. But the insulating capabilities of polyethylene are not unlimited: if a certain limit is exceeded, a breakdown will occur and the cable line will completely fail. And replacing a cable laid underground or under water is a troublesome business.

So what's the deal with carbon soccer balls? It turned out that if fullerene molecules are added to polyethylene, then its insulating qualities increase. Fullerene-modified cable withstands higher voltage than conventional cable - 26% higher. And this means that 26% more energy can be transmitted through it. To achieve this effect, Swedish chemists have created an insulating material in which there is one gram of fullerene per kilogram of polyethylene.

Fullerene has very peculiar electronic properties. It can trap high-energy electrons that destroy the insulating properties of polyethylene. Fullerene accepts such electrons, saving the polymer from possible breakdown. Although this discovery is not one of those that make a revolution in the energy sector, but in industry, increasing efficiency by every percent saves tons of materials and megawatts of power.
