4. Safety requirements in emergency situations

4.1. When servicing and repairing electrical equipment, a fire may occur as a result of a malfunction of electrical equipment, electric shock to others as a result of a broken cable (wire) or ground fault, and other emergencies.

4.2. In the event of a fire in the power plant or a danger of electric shock or a short circuit, it is necessary to de-energize the installation, take measures to extinguish the fire and inform the foreman or work manager about this. Flames should be extinguished with carbon dioxide or powder fire extinguishers, asbestos blankets and sand.

4.3 When a ground fault is detected, it is forbidden to approach the fault location at a distance of less than 4 m in closed and less than 8 m in open switchgears (RU). Approaching this place at a closer distance is allowed only for operations with switching equipment to eliminate ground faults, as well as, if necessary, providing first aid to the victims. In these cases, it is imperative to use both basic and additional electrical protective equipment.

4.4 The electrician should remember that after the power failure in the power plant, it can be re-applied without warning.

4.5. In the event of an accident at work, it is necessary to quickly release the victim from the traumatic effect (high outside temperature, electric current, compressive weights, etc.), take measures to provide the victim with first aid and call a doctor.

4.6. To release the victim from the action of the current, it is necessary to quickly disconnect the current-carrying parts or wires that he touches. If it is impossible to turn off the power plant to separate the victim from current-carrying parts with a voltage of up to 1000 V, it is necessary to take measures of one's own safety, for which, in dry weather, pull the victim by the parts of clothing that are not adjacent to the body (sleeve, suit hems). If possible, remove the current-carrying part with an object insulator (dry board). You can isolate yourself from the action of the current, for which you need to stand on a dry board, a dielectric mat and put on dielectric gloves. It is safer to disconnect the victim and the current-carrying part with one hand.

At voltages in live parts above 1000 V, they also act, but in dielectric gloves and boots, using special rods and tongs designed for the appropriate voltage.

4.7. After the release of the victim from the action of the electric current, depending on his condition, he is provided with first aid. The victim should unfasten clothing that restricts breathing. When breathing stops and the heart stops, it is necessary to do artificial respiration, closed heart massage.

4.8. In all cases of injury or sudden illness, you must contact the health center of the enterprise (tel. _______), call a doctor or take the victim to the nearest medical facility.

4.9. In case of accidents and accidents, the manager should be immediately notified, and the safety of the situation should be ensured before the start of the investigation, if this does not pose a danger to the life and health of people.

4.10. The electrician is prohibited from leaving the workplace during the liquidation of the accident until it is completely eliminated without the permission of the work manager.

5. Safety requirements upon completion of work

5.1. At the end of the work, the electrician must:

• inspect the electrical installation on which the repair was carried out and make sure that no objects were left there that could lead to a short circuit or breakage at the time of energization;
• put the workplace in order, put the tools, devices and PPE in the places provided for storage;

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. ... >>

Random news from the Archive Innovative 4D NAND Flash 08.11.2018 Korean company SK Hynix, the second largest chip manufacturer in the world, introduced the first ever innovative 4D NAND flash memory. The novelty is a 96-layer TLC NAND memory that uses charge trap (CTF) and PUC (Peri. Under Cell) memory technologies. The density of the crystal is 512 Gbit. The prefix 4D means the use of not only the vertical integration of memory cells, but also the placement of peripheral circuits in the underlying layer. A similar layout has been seen before, as well as CTF technology. SK Hynix's innovation lies in the simultaneous use of both CTF and PUC. The new solution made it possible to reduce the size of the chip by more than 30%, while the number of chips per wafer, on the contrary, increased by 49% compared to 72-layer 3D NAND crystals of the same density.
