immediately stop work and disconnect the station from the mains, using the emergency shutdown controls if necessary;
Report all malfunctions and the measures taken to eliminate them to the work manager.

5.3. If an accident occurs during work, the driver is obliged to immediately turn off the station and provide first aid to the victim, report the incident to the work manager and take measures to preserve the situation of the accident, if this does not threaten the life and health of people.

5.3. If there are victims, it is necessary to provide them with first aid, if necessary, call an ambulance.

5.4. Providing first aid.

5.4.1. First aid for electric shock.

In case of electric shock, it is necessary to immediately release the victim from the action of electric current by disconnecting the electrical installation from the power source, and if it is impossible to disconnect it, pull it away from the conductive parts by clothing or using insulating material at hand.

If the victim has no breathing and pulse, it is necessary to give him artificial respiration and indirect (external) heart massage, paying attention to the pupils. Dilated pupils indicate a sharp deterioration in the blood circulation of the brain. In this state, the revival must begin immediately, and then call an "ambulance".

5.4.2. First aid for injury.

To provide first aid in case of injury, it is necessary to open an individual package, apply a sterile dressing material, which is placed in it, to the wound and tie it with a bandage.

If somehow the individual package was not found, then a clean handkerchief, a clean linen rag, etc. must be used for dressing. On a rag that is applied directly to the wound, it is advisable to drip a few drops of tincture of iodine to get a stain larger than the wound, and then apply the rag to the wound. It is especially important to apply the tincture of iodine in this way to contaminated wounds.

5.4.3. First aid for fractures, dislocations, shocks.

In case of fractures and dislocations of the limbs, it is necessary to strengthen the damaged limb with a splint, plywood plate, stick, cardboard or other similar object. The injured arm can also be hung with a bandage or handkerchief from the neck and bandaged to the torso.

In case of a skull fracture (unconsciousness after a blow to the head, bleeding from the ears or mouth), it is necessary to apply a cold object to the head (a heating pad with ice, snow or cold water) or make a cold lotion.

If a fracture of the spine is suspected, it is necessary to put the victim on the board, without lifting him, turn the victim on his stomach face down, while observing that the body does not bend, in order to avoid damage to the spinal cord.

In case of a fracture of the ribs, a sign of which is pain during breathing, coughing, sneezing, movements, it is necessary to tightly bandage the chest or pull it off with a towel during exhalation.

5.4.4. First aid for burns with acids and alkalis.

If acid or alkali gets on the skin, the damaged areas must be thoroughly washed with water for 15-20 minutes, after which the acid-damaged surface should be washed with a 5% solution of baking soda, and the burnt with alkali - with a 3% solution of boric acid or an acetic solution. acids.

In case of contact with the mucous membrane of the eyes of acid or alkali, it is necessary to rinse the eyes thoroughly with a stream of water for 15-20 minutes, wash them with a 2% solution of baking soda, and burnt alkali with a 3% solution of boric acid or a 3% solution of acetic acid. acids.

In case of burns of the oral cavity with alkali, it is necessary to rinse with a 3% solution of acetic acid or a 3% solution of boric acid, for acid burns - with a 5% solution of baking soda.

If acid enters the respiratory tract, it is necessary to breathe with a 10% solution of baking soda sprayed with a spray bottle, if alkali enters, a sprayed 3% solution of acetic acid.

5.4.5. First aid for thermal burns.

In case of burns with fire, steam, hot objects, in no case should you open the formed blisters and bandage the burns with a bandage.

For first-degree burns (redness), the burned area is treated with cotton wool soaked in ethyl alcohol.

For second-degree burns (blisters), the burned area is treated with alcohol or a 3% manganese solution.

For third-degree burns (destruction of skin tissue), the wound is covered with a sterile dressing and a doctor is called.

5.4.6. First aid for bleeding.

In order to stop bleeding, you must:

raise the injured limb up;
close the bleeding wound with a dressing (from a bag) folded into a ball, press it from above, without touching the wound itself, hold for 4-5 minutes. If the bleeding stops without removing the applied material, put another pad from another bag or a piece of cotton on top of it and bandage the wounded area (with some pressure);
in case of severe bleeding that cannot be stopped with a bandage, compression of the blood vessels that feed the wounded area is applied by bending the limb at the joints, as well as with fingers, a tourniquet or a clamp. In case of heavy bleeding, you should immediately call a doctor.

5.5. Follow the instructions of the head of work to eliminate the emergency.

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. ... >>

Gaming OLED TVs from LG 07.09.2019

In recent years, gamers have become one of the most powerful engines of the electronics industry. So, for example, while the market for personal computers and laptops is regularly declining, their gaming options, on the contrary, fly like hot cakes. Not surprisingly, many manufacturers are now asking the question: "What else would be released specifically for gamers?".

While some are churning out gaming smartphones, the Korean company LG decided to show originality and introduced special gaming TVs. A line of OLED models (model 65/55E9 and model 77/65/55C9) received support for Nvidia G-Sync technology. That is, if you connect a personal computer with an Nvidia video card to such TVs, you will receive automatic synchronization of the refresh rate of the graphics accelerator and the screen.

The new game line includes models with a diagonal of 55 to 77 inches. All of them have a resolution of 4K and a maximum frame rate of 120 Hz, which is very pleasant for games. The lag for 1440p content is 6 milliseconds, and for 4K video - 13 milliseconds, which is the best among all TVs of the brand.
