low air humidity and high temperature
insufficient illumination of the working area;
fire hazard;
falling personnel while working on ladders and ladders;
falling objects from a height (tools, equipment items).

3. Labor protection requirements during work

3.1. Maintenance of devices located in the upper parts of the cabinets should be carried out only from serviceable, marked stepladders.

3.2. It is forbidden to work from the two upper steps of step-ladders without railings or stops, as well as to be on the steps by more than one person.

3.3. Changing individual fuses should be done with only one hand, and the second or part of the body should not touch grounded structures.

3.4. The replacement of an ordinary fuse must be carried out by two persons, one of whom must stand at the bottom of the stepladder.

3.5. When changing individual fuses on racks, use pliers with insulated handles.

3.6. Equipment racks that have voltages greater than 42 V AC and 110 V DC must have dielectric mats in front of them.

3.7. It is forbidden to allow persons who are not related to their maintenance to the rectifiers; all repair work in the rectifier cabinet should be carried out only after disconnecting the DC and AC voltages from the rectifier or turning off the repair switch; keep the rectifier cabinet closed.

3.8. After turning off the rectifier or other equipment for preventive maintenance or current repairs, the voltage must be removed from the power switchboard with a repair switch, and a poster is posted on the switch drive: "DO NOT SWITCH ON - PEOPLE WORK!". This poster can only be removed by the worker who hung it after the work is completed.

3.9. It is necessary to disconnect the equipment from the diesel installation, which can automatically turn on in the event of a power failure in the supply network.

3.10. Before carrying out work on a compensating capacitor unit (CCU), it is necessary to discharge the capacitors with a discharge bar.

3.11. It is forbidden to use metal ladders.

3.12. Measurements with portable devices and current clamps must be carried out by two persons, one of whom must have an electrical safety qualification group of at least IV, and the second - at least III.

4. Labor protection requirements in emergency situations

4.1. Each employee who discovers a violation of the requirements of this instruction and labor protection rules or notices a malfunction that poses a danger to people is obliged to report this to the immediate supervisor.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean.

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. ... >>

25 inch nanotube TV 15.01.2006

Applied Nanotech showcased a working prototype of a 25-inch carbon nanotube color display built in collaboration with six Japanese companies.

Of course, there is still work to be done on the image quality, but at the same time, the fact is noted that such a display completely lacks the effects inherent in liquid crystal and plasma displays due to their inertia. The prototype resolution is only 280x200, but in fact, the technology is proposed to be used in larger displays with a diagonal of 60 to 80 inches and a resolution of 1280x720 (HDTV), on which the image will look much less grainy.

It is assumed that the use of displays based on nanotubes will significantly reduce the price of TVs with large diagonals due to the use of relatively inexpensive inkjet printing technologies in the production and the compatibility of such displays for the necessary control voltages with cheap CMOS binding.
