Persons who have reached the age of 18, have passed a medical examination and have no medical contraindications, have been theoretically and practically trained according to a special program (including on the topic: "Releasing the victim from electric current, providing him with first aid") after certification are allowed to work in electrical installations. qualification commission. Subsequently, the medical examination is repeated once every 2 years. Recertification of workers - annually, and engineering and technical workers - every 3 years. The qualification group of personnel is confirmed by a certificate (except for group I). There are five qualification groups in total. The most responsible of them is Group V. Only persons with a qualification of at least group II are allowed to service electrical installations. Persons servicing technological equipment with an electric drive must have knowledge in the scope of I or II group.

Enterprises should develop local instructions in which it is recommended to provide sections based on the "Rules for the operation of electrical installations of consumers" and "Safety regulations for the operation of electrical installations of consumers" and other Safety Rules according to the following schemes.

For operational and maintenance personnel when servicing electrical installations with voltage up to 1000 V:

inspection of electrical installations; operational switching; manufacturing jobs; technical measures to ensure the safety of work; production of outages; placement of warning posters, fencing of the workplace; voltage absence check; the procedure for applying and removing grounding; organizational measures to ensure the safety of work; filing a job assignment; supervision during work; registration of a break and end of work; work without removing the voltage and in emergency cases.

A list of persons of the administrative and technical personnel of workshops and departments of the enterprise who have the right to give oral, telephone and written orders for the performance of work in electrical installations with voltage up to 1000 V should be attached to the local instructions.

For operating and maintenance personnel when servicing electrical installations with voltages above 1000 V:

operational requirements. and maintenance personnel production of operational switching; manufacturing jobs; organizational measures to ensure the safety of work; technical measures to ensure the safety of work; measures to ensure the safety of work without removing the voltage near and on live parts under voltage.

The indicated local instructions are reproduced (preferably in a typographical way), issued against receipt for execution and control, to each employee; posted in safe working areas.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Handheld x-ray scanners 17.01.2013

Engineers at the University of Missouri have developed a compact X-ray source that is about the size of chewing gum. This development will create hand-held X-ray machines needed by doctors and security services.

Modern x-ray machines are too bulky and consume a lot of electricity. The new device is based on lithium niobate crystals, which have piezoelectric properties and act as voltage boosters. During the experiments, the new device was able to raise the voltage from 10 volts to 100 thousand volts. The lithium niobate crystal is an X-ray source: vibration energy is extracted in the form of a high-voltage electron beam, which is decelerated by a metal plate and produces X-rays.

The developers believe that in 3 years, based on the new technology, they will be able to create a compact X-ray machine, which is needed in many industries. A handheld X-ray scanner is useful for searching for defects in various designs, for examining luggage, on space technology, such as rovers. In medicine, portable x-ray machines are especially needed: imagine that dangerous radiation when taking a picture of a tooth will not be directed into the oral cavity, but vice versa - a “pill” emitter will be attached from the inside. It is possible that the power of the emitter can be increased hundreds of times, and then the military and special services will be interested in this invention, because the piezoelectric X-ray emitter will become a powerful secretive weapon that can kill a person.
