In the area of underground utilities (electric cables, gas and water pipes, etc.), earthworks are allowed only with the written permission of the organization responsible for their operation. Soil development in the immediate vicinity of existing underground utilities is allowed only with the help of shovels, without sharp blows, it is prohibited to use impact tools (crowbars, picks, wedges, pneumatic tools, etc.).

3.2. If underground structures are found that are not indicated in the drawings, earthworks should be immediately stopped until the nature of the discovered structures is clarified and an appropriate permit for further work is obtained.

3.3. For the passage of workers into the pits and trenches, ladders or ladders should be installed.

3.4. The vertical walls of pits and trenches, if necessary, must be reinforced with ladder-type fasteners or wooden shields.

3.5. The place of work is fenced with the installation of warning inscriptions and signs, and signal lighting is installed at night.

3.5. Before opening the sleeves or cutting the cable, you must make sure that these operations will be performed on the cable on which you need.

3.6. The cable to be repaired should be determined by the joints of the building by tracing, checking the folds according to the diagrams and drawings when laying in the ground.

3.7. Before cutting the cable or opening the coupling, it is necessary to check the absence of voltage using a special tool. The puncture of the cable is carried out by the head of work or allowing under his supervision. The cable should be pierced with dielectric gloves using goggles.

3.8. The cable mass for pouring the couplings is heated in a special metal container from the roofs; oh and a nose. Heating unopened cans of cable mass is prohibited.

3.10. While soldering the cable cores, it is necessary to hold the clip-forms with pliers, remove carbon deposits from the surface of the molten solder with a spoon, which is heated before use. The mother of the clip-form is necessary only after the end of soldering and cooling them. When soldering, care must be taken not to burn the cable cover. To avoid overheating of the paper insulation, soldering must be done as quickly as possible (3-4 minutes). The outer jute covers must be carefully removed from the cables.

3.11. At night, the workplace should be lit.

4. Safety requirements after completion of work

4.1. After the completion of hot work, it is necessary to carefully inspect the workplace, pour water on burning materials and eliminate violations that could lead to a fire.

4.2. Tidy up the workplace, remove the tool, blowtorch, cleaning material.

4.3. Backfill an open pit or trench.

4.4. Bring the land occupied for installation and repair work to its previous state.

5. Safety requirements in case of emergencies

5.1. During earthworks, if explosive materials and ammunition are found, work is immediately stopped, work can be resumed only after they have been removed by sappers.

5.2. If malfunctions are detected in the form of leakage of the blowtorch reservoir, its deformation, etc. work must be stopped immediately and the lamp handed over for repair.

5.3. In case of ignition of the cable mass, to extinguish the fire, use an asbestos blanket made of non-combustible heat-insulating fabric, coarse woolen fabric or felt.

5.4. It is allowed to resume hot work only after all fire safety requirements have been met (availability of fire extinguishing equipment, cleaning the workplace from combustible materials, protection of combustible cable structures, etc.).

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. ... >>
