Occupational Safety and Health / Providing first aid to the injured

In case of accidents while working on VL supportswhen the victim is unconscious, you need to be able to quickly remove him from the support. For this, the team conducting work on the overhead line must be equipped with special devices:

single-roller block with a device for attaching it to a support;
nylon or cotton rope with a diameter of at least 10 mm and a length of at least twice the height of the support (20 m or more);
electrical protective equipment corresponding to the voltage of the overhead line on which the work is carried out.

Block, designed to lower the victim from the support, must be constantly ready for use and tucked in with a rope.

When starting to lower the victim from the support, it is necessary to take measures to exclude the possibility of electric shock and falling from the height of the person providing assistance. To prevent the possibility of electric shock, it is necessary to observe the permissible distances to the wires of the overhead lines under voltage, defined by the "Safety Rules for the Operation of Electrical Installations". If the allowable distances cannot be observed, then the overhead line must be turned off by a switching device or by creating an artificial short circuit by means of a surge on overhead lines with a voltage of up to 20 kV inclusive. You can climb to the victim using special mechanisms (towers) or devices for climbing supports (manholes, claws). Be sure to use a fitter's belt and a protective helmet.

Climbing onto the support, you should take with you the block prepared for lowering the victim (assembly).

The block must be securely fastened to the structural elements of the support (traverse, hooks, etc.) above the victim. Then tie one end of the rope on the fitter's belt of the victim or pass a loop under his hands so that during the descent he is in a vertical position and does not slip out of the loop. Lower the other end of the rope to the ground. The end of the rope that falls to the ground should be wrapped 1-2 times around any cylindrical element of the support (stand, hook, traverse, etc.) to create a braking moment during descent and avoid additional injury to the victim.

Having climbed onto the support, you should quickly determine the condition of the victim and, if necessary, take resuscitation measures, make two blows into his lungs, and then, without delay, lower him to the ground. To do this, a person standing on the ground must, by pulling the rope, slightly raise the victim in order to enable him to free him from the claws (manholes) and the fitter's belt on which he hangs. After detaching the victim from the support, he must be quickly and carefully lowered to the ground and continue first aid.

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. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Discovered a new way to preserve vitamins in food 12.12.2022

Boiling, freezing, drying foods and many other factors destroy vitamins. Therefore, such food becomes less useful.

Scientists from the Massachusetts Institute of Technology have developed a new way to fortify food with vitamin A. This will help improve the health of millions of people around the world.

In a new study, they showed that encapsulating vitamin A in a protective polymer prevents the nutrient from being destroyed during food preparation or storage. Scientists plan to include such vitamins in flour or bouillon cubes.

"We wanted to check whether vitamin A can retain its effect during cooking, and whether it will be destroyed under the influence of various factors," said Anna Jaklenek, the author of the study.

To protect the vitamin from degradation, the scientists mixed it with a polymer to form particles 100 to 200 microns in diameter. They also coated them with starch to prevent sticking. These encapsulated particles were incorporated into flour and bouillon cubes. It turned out that foods enriched with vitamin A remained useful even after boiling and under the influence of high temperatures.

"Food fortified with our vitamin A can provide the recommended daily allowance, even after prolonged storage or exposure to high temperatures," adds Wen Tang, co-author of the study.
