5.4. If an accident occurs, it is necessary to provide first aid to the victim; if necessary, call emergency medical assistance.

5.5. Providing first aid.

5.5.1. 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.

5.5.2. 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.

5.5.3. 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 (unconscious state after a blow to the head, bleeding from the ears or from the 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.

5.5.4. 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 (blister), the burned area is treated with alcohol or a 3% manganese solution or a 5% tannin solution.

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

5.5.5. First aid for bleeding.

5.5.5.1. Raise the injured limb up.

5.5.5.2. Close the 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).

5.5.5.3. 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.

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

5.7. 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. ... >>

Random news from the Archive If a bee stings a bacterium 05.03.2005 Bee venom may be able to replace antibiotics. The main component of bee venom, mellitin, a peptide (small molecule protein) consisting of 26 amino acids, has been shown to kill bacteria by destroying their shells. Moreover, bacteria that have developed resistance to antibiotics also succumb to it. Biochemists from the Queen's University in Belfast (Ireland) identified two types of mellitin: one is especially toxic to microbes, but destroys the shell of human red blood cells, the other does not harm red blood cells, but is not very dangerous for bacteria either. Scientists hope to use genetic engineering to combine both molecules into one, retaining only useful properties in this hybrid.
