4.32. In electrical installations with voltage up to 1000 V, it is not allowed to use "control" lamps to check the absence of voltage due to the risk of injury from an electric arc and glass fragments.

4.33. Before performing work related to climbing to the support, the following safety requirements must be strictly observed:

  • immediately before climbing onto the support, you must make sure that it is stable and strong. If the strength of the support is in doubt (insufficient penetration, swelling of the soil, rotting of wood, concrete cracks, slope above the norm, etc.), it is not allowed to climb it without strengthening it;
  • check the strength of the support by digging out the support post to a depth of 30-40 cm below ground level; determine the degree of decay of wooden supports with the help of tools and fixtures, and for reinforced concrete supports and attachments - the integrity of the concrete.

Climbing and working on a support is allowed only in cases where there is full confidence in its sufficient stability and strength.

If the strength of the support is in doubt, then it must be strengthened with special stretch marks without climbing onto the support or working from a TV tower.

4.34. When climbing onto a support, it is necessary to use fitter's claws, manholes, safety belts. The safety belt lanyard should be wound behind the rack.

While working on a support, it is necessary to lean steadily on both pits (manholes) and be fixed with a safety belt.

4.35. On overhead lines, when checking the absence of voltage, performed from wooden or reinforced concrete supports with a voltage indicator of the UVN-10, UVN-80 type, it is necessary to ground its working part.

The voltage gauge should be used with dielectric gloves.

4.36. On overhead lines, when hanging wires at different levels, check the absence of voltage with a pointer and install a grounding rod from the bottom up, starting from the bottom wire. If the wires are suspended horizontally, the test should be started from the nearest wire.

4.37. It is not allowed to break the integrity of the wires and remove the bindings on the intermediate supports, if this will cause one-sided tension of the wires, without first strengthening the supports in order to prevent them from falling.

4.38. On corner supports with pin insulators, it is not allowed to climb and work from the side of the inner corner.

4.39. When performing work at height using a portable wooden ladder, it is necessary to verify its suitability by the test stamp and visual inspection.

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. ... >>
