4. Safety requirements after finishing work

4.1. Clean the cement truck from dirt, check the condition of the components, eliminate the identified malfunctions, put the cement truck in the place intended for parking and brake with the parking brake.

4.2. When uncoupling the tractor and tank-semi-trailer, the driver must:

4.2.1. Lower the supporting device of the tank-semi-trailer to the stop to the surface of the road (site) and move the tractor in reverse until the supporting devices are transferred to the forward position.

4.4. Wash hands, face with warm water and soap; shower if possible.

4.5. Report to the head of work on all the shortcomings that occurred during work.

5. Safety requirements in emergency situations

5.1. An emergency situation, in addition to those set out in the instructions for truck drivers, may additionally arise in the event of: failure of the compressor, coupling device; rupture of air ducts; failure of safety and check valves; depressurization of the tank; getting cement in the face and so on.

5.2. If this situation occurs, you must stop working.

5.3. Report what happened to the supervisor.

5.4. If an accident occurs, provide first aid to the victim; if necessary, call an ambulance.

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 (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.

5.5.4. First aid for burns with acids and alkali.

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.

5.5.5. First aid for bleeding.

5.5.5.1. Raise the wounded ending 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, squeezing of the blood vessels that feed the wounded area is applied by bending the ends in the joints, as well as with fingers, tourniquet or twist. In case of heavy bleeding, you should immediately call a doctor.

5.6. In the event of a fire, call the fire brigade and start extinguishing the fire with primary fire extinguishing equipment.

5.7. In all cases, follow the instructions of the head.

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 Nanowires for silicon photonics 24.04.2014 IBM developers have succeeded in creating gallium arsenide nanowires that have properties useful for silicon photonics. Today, work with elements from groups III-V of the periodic system is considered as one of the possibilities for ensuring further progress in the development of semiconductor technologies. The most commonly used of these groups are gallium and indium arsenide alloys. These alloys are distinguished by high electron mobility and can be used as a basis for various tunneling effects, which implies the ability to operate at very low energy levels. The IBM division in Zürech has been able to exploit other interesting properties of these alloys. IBM developers have created sections on an ordinary silicon wafer that include nanowires of mechanically strained gallium arsenide. By changing the mechanical load on the nanowires (compressing and stretching them), it was possible to achieve such a change in the electrical properties of the "wires" that they either emitted photons or absorbed them. This property is well suited, for example, to create a so-called. silicon photonics, when optical transceivers are built directly into processors and controllers. In this case, it is possible to change the radiation spectrum by dosing the mechanical load, thereby compacting the data transmission channel.
