3.7. When working with a powder mandrel, the operator must know a comfortable and stable position in such a way that the axis of the mandrel and charging rod and the recoil trajectory of the hammer do not intersect with the operator’s body and eliminate the possibility of hitting nearby objects and structural parts with his hand.

3.8. It is not allowed to drive dowels into building foundations whose strength is higher than the strength of the dowels, as well as into foundations that are fragile.

3.9. When working with a powder impact column, you should hold it strictly perpendicular to the wall or ceiling (base) in which the hole is to be punched.

3.10. During charging, the guide cylinder of the column must be held by the cylindrical part so that an accidental shot does not cause injury to your hand.

remove or replace the locking and safety mechanism of the tool;
point a pyrotechnic instrument at yourself or towards other persons, even if it is not loaded with a cartridge;
leave a pyrotechnic instrument and cartridges for it without supervision;
transfer a pyrotechnic instrument and cartridges for it to other persons, including those who have a certificate for the right to use this instrument;
charge the tool until the workplace is fully prepared;
unload the tool immediately after releasing the firing pin, if the shot does not occur. You can only discharge after 1 minute.
to disassemble and clean the pyrotechnic instrument.

3.14. Before submitting for repair or inspection or returning to the storeroom, the operator must check and make sure that the tool is unloaded (the cartridge has been removed).

3.15. A pyrotechnic instrument can only be handed over to the storekeeper (who issued the instrument) or to a responsible person entrusted by the administration of the organization with monitoring the correct use of the pyrotechnic instrument.

3.16. Before starting work on punching holes, it is necessary to clarify the location of voids in the concrete.

3.17. During charging, the guide cylinder of the powder percussion column must be held by the cylindrical part so that in case of an accidental shot there is no injury to the hand.

3.18. Before firing, it is necessary to check the reliability of the locking of the powder striking column, take a comfortable position (during the shot, significant recoil forces will be transferred to the hands), and a protective shield should be put on the face.

3.19. When working with powder presses of the PPO-95 type, you should not use a powder charge of greater power than recommended in the instructions.

3.20. Before firing, it is necessary to check that the powder press is locked, and the tip or cable core is completely in the matrix socket and clamped by the casing.

3.21. It is not allowed to shoot from a powder press if the tip or cable core is not clamped by the casing or is not pressed tightly against it.

3.22. To withdraw the members of the brigade from the place of work for the duration of breaks during the work shift, while the work permit remains with the responsible performer of the work. Resume work after a break, only personally inspecting the workplace.

4. Labor protection requirements in emergency situations

4.1. If you find defects in the operation of a pyrotechnic instrument that pose a danger to human life, immediately stop work, take measures to eliminate the accident, and report the incident to your supervisor.

4.3. In the event of a fire, immediately call the fire brigade, take people to a safe place and, if possible, remove combustible substances, start extinguishing the fire with primary fire extinguishing equipment, extinguishing with dry sand or a carbon dioxide fire extinguisher. Report the fire to the manager.

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. ... >>

Concrete will become stronger 12.04.2020

Concrete is called "artificial stone" for its strength. But can it be made even stronger? Australian scientists can say for sure and answer this question in the affirmative. They have developed a technique that makes traditional concrete 17% stronger, which can be extremely important when pouring critical and large structures. At the same time, the technology is relatively low-cost and has a positive effect on the environment.

The researchers drew attention to how the properties of the concrete mix ... slag. We are talking about steel production waste. It turns out that in the process of smelting steel alloys, a lot of slag remains, which is often not used in any way. On a global scale, we are not talking about 130 tons of steel slag that need to be disposed of. The Australians claim that now construction companies will buy it themselves as a valuable additive in concrete.

The fact is that slags are something like a sponge that absorbs metals until completely saturated. They also absorb water, pre-purifying it of impurities. If such slag is added to the prepared concrete, then its strength increases significantly. The best results are achieved if the water driven through the slag masses has been pre-enriched with phosphorus.

This technology has room for development. It has been established that phosphorus in agriculture plays the role of waste that is harmful to the environment. By using such waste to enrich the water used to soak the slag, several complex problems can be solved at once with minimal cost. Scientists are confident that the development and implementation of such techniques will improve the ecology on Earth.
