3.10. The absence of extraneous dangerous voltage on the torso and cable should be checked. Check with a voltage indicator. To check the presence of extraneous voltage on the cables and cables of the communication line and wire broadcasting, which have overhead intersections with power lines with voltages above 1000 V, it is necessary to use high-voltage indicators.

After it is established that there is no extraneous voltage above 1000 V on the cables and cables of communication and wire broadcasting, using a low voltage indicator, you must make sure that there is also no extraneous voltage below 1000 V on the cables and cables of communication and wire broadcasting. only one low voltage indicator of the type INN-1 to determine the presence of extraneous voltage on cables and cables for communication and wire broadcasting that intersect with power lines with voltages above 1000 V is prohibited

3.11. It is forbidden to work on a cable support when approaching or during a thunderstorm, with a wind of more than 15 m per second, during snowstorms.

3.12. On overhead cable communication lines and wire broadcasting, the steel cable to which the cable is suspended must be grounded.

4.1.1. Immediately stop work and notify the person responsible for the work;

4.1.2. Under the guidance of the person responsible for the production of works or personally to the electrician, take measures to eliminate the causes of accidents or accidents;

4.1.3. About victims of accidents (injured) or those who have undergone a sudden illness, it is necessary to notify the head, report to the first-aid post and take measures to provide the necessary first aid.

5. Labor protection requirements at the end of work

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

5.1.1. Tell the person. responsible for the completion of work, and about all the shortcomings noticed during the work and the measures taken to eliminate them.

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. ... >>

High-strength steel for buildings and armored vehicles 19.11.2012

A research team at Wayne State University has developed the toughest bainitic steel with microstructures composed of ferrite and stabilized carbon austenite.

Despite significant progress in the creation of new grades of high-strength steel, various industries feel an urgent need for lighter and stronger structures. New metals should improve energy efficiency, reduce environmental pollution, improve transport safety, and so on.

American scientists have been working on the creation of new materials with high yield strength, high impact strength and ductility. As a result, it was possible to create a new material consisting of bainitic steel and ductile iron of isothermal hardening. The new material has all the desired characteristics, in particular, excellent resistance to fatigue wear, which can ultimately lead to unexpected collapses of structures and deaths.

The secret of the new metal lies in a special processing technique based on isothermal hardening with holding in the bainite region (austempering). This type of heat treatment is more energy efficient and does not require subsequent additional heat treatment, which saves energy. The new steel has extremely fine-scale microstructures consisting of ferrite and austenite, and also contains a large amount of silicon.

The new metal is made from traditional raw materials and can be processed in common ways. At the same time, it has excellent characteristics and can be used in a variety of areas. So, during ballistic tests in Canada, the new steel demonstrated excellent armor qualities in terms of protection against the effects of a blast wave and shrapnel. Thus, the strength and durability of the new steel allows it to be used for the manufacture of armored vehicles and strengthening buildings.
