increased level of electromagnetic radiation of very high (VHF) or ultra-high (UHF) frequencies;
increased noise level in the workplace;
increased air temperature in the workplace;
other factors determined by the geographical location of the RRS (desert, tundra, regions of the Far North, high mountains, etc.), its design (ordinary room, container version, recessed or located in a cabin on a tower, etc.).

1.7. Employees who carry out work on the adjustment of automation and telemechanics of the RRL must be provided with special clothing, special footwear and other personal protective equipment in accordance with applicable regulations and are responsible for their correct application, use and safety.

1.8. Each employee must study the fire and explosion safety requirements, comply with them and be able to use the primary fire extinguishing equipment available in the hardware.

1.10. For violation of the requirements of labor protection instructions, employees of enterprises are subject to disciplinary, administrative, and, in appropriate cases, material and criminal liability in the manner prescribed by current legislation.

2. Labor protection requirements before starting work

2.1. Prior to the start of work on the adjustment of RRL automation and telemechanics, it is necessary to obtain permission or an order from the RRL junction or terminal station. At the same time, the scope, start and end times of work must be precisely determined, and all persons responsible for the production of work must be appointed. Reception of equipment for setting up automation and telemechanics of the RRL is recorded in the journal of the shift supervisor.

2.2. The admission of the brigade is made after checking the implementation of technical measures in the amount corresponding to work without stress relief, and is carried out by the shift supervisor and is recorded in the operational log signed by the shift supervisor and the foreman.

2.3. When preparing a workplace for a team that adjusts RRL automation and telemechanics, the shift supervisor must hang warning and prescriptive posters, protect workplaces and live parts remaining energized if necessary.

2.4. Before admission, the shift supervisor must:

check the composition of the brigade, the adequacy of the qualifications of its members;

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. ... >>

Drone - helium balloon 20.11.2021

Despite the ease of use, multicopter drones make quite a lot of noise during operation, consume a lot of energy, and besides, they are potentially dangerous due to rotating blades. An alternative was presented by the Japanese company NTT Docomo, releasing a balloon-like drone that moves extremely quietly.

Classic drones with spinning blades pose some threat to humans, animals, and even other drones. Many of them use sensors and sophisticated algorithms for avoiding obstacles, some manufacturers create special casings to protect against the consequences of collisions and other solutions to maintain functionality even after an incident.

Docomo's idea is much simpler - get rid of the blades completely. The new drone is essentially a balloon filled with helium. The bottom-mounted camera allows you to take photos and videos, and the drone also has a multi-colored LED backlight that can be turned on as needed.

The main advantage of the novelty is that it practically does not make sounds in flight. In addition, there is no need to constantly maintain the device in the air due to the use of an inflatable ball in the design, which ensures a long time of autonomous flight.

An exclusive component of the Docomo drone is its propulsion system. Miniature ultrasonic modules are mounted on a lightweight frame, generating microvibrations in the air - they allow the drone to move in any direction.

Balloon drones have been around for quite some time, but some still use propellers and others are balloon-kite hybrids designed to operate at high altitudes. Docomo says its solution is perfect for use during any kind of event, indoors or outdoors (we can assume that the weather for this should be close to ideally calm).
