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 of recovery, it is necessary to start 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.

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 torso 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 rinsed with a stream of 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.

If acid or alkali gets on the mucous membrane of the eyes, it is necessary to thoroughly rinse the eyes with a stream of water for 15-20 minutes, then rinse with a 2% solution of baking soda, and if the eyes are damaged by alkali, with a 2% solution of boric acid.

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 a 10% solution of baking soda sprayed with a spray gun, 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 bubbles that form and tie 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, a 3% manganese solution or a 5% tannin solution.

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

5.4.6. First aid for bleeding.

5.4.6.1. Raise the injured limb up.

5.4.6.2. Close the bleeding wound with a dressing (from a bag) folded into a ball, press down 2 from above, without touching the wound itself, hold for 4-5 minutes; if the bleeding has stopped, then, 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).

5.4.6.3. With severe bleeding that cannot be stopped with a bandage, squeezing of the blood vessels that feed the wounded area is applied by bending the limbs at the joints, as well as with fingers, tourniquet or twist; in case of heavy bleeding, it is necessary to urgently call a doctor.

5.5. If a fire occurs, start extinguishing with the available fire extinguishing equipment. If necessary, call the fire department.

5.6. Follow all instructions of the head of work to eliminate the danger.

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. ... >>

Found a way to hear the fish inside the aquarium 31.01.2018

Physicists from Japan and South Korea have developed a metamaterial that transmits about 30 percent of the energy of sound waves.

The new metamaterial will make it possible to use sensitive condenser microphones for recording underwater sounds and significantly increase the quality of such recordings.

If the fish were constantly screaming, then people would still not notice it - 99,9 percent of the energy of sound waves is lost when passing through the water-air border. The metamaterial significantly reduces these losses: when using it, about a third of the wave energy passes through the interface. With it, conventional air microphones can be used to record underwater sounds. In this way it will be possible to hear the sounds inside the aquarium.

The fact is that the water-air interface transmits sound very poorly. The acoustic resistance of water is 3600 times greater than that of air, and therefore the energy of a sound wave when passing through their border decreases by almost three orders of magnitude. This is easy to check for yourself by tapping, for example, with two stones in the air and under water - if you hear how the stones click when hit in the water, the sound will reach your ears through your hands and body rather than through water and air.
