Emergencies, their types. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

Emergency - a state in which, as a result of the occurrence of a source of an emergency situation in a certain territory or water area, the normal conditions of life and activity of people are violated, their life and health are threatened, damage is caused to the population, the national economy and the natural environment.

Emergencies are divided into man-made, anthropogenic, natural, as well as by the types and types of events underlying these situations, by the scale of distribution, by the complexity of the situation, and the severity of the consequences.

Classification of emergency situations objects of the economy by potential hazard:

1) with the release of mechanical energy - explosions, damage or destruction of mechanisms, assemblies, communications, collapse of structures and buildings; hydrodynamic; dam failures with ensuing consequences;

2) with release of thermal energy - fires, explosions in buildings on technological equipment; fires at the objects of production, processing, storage of flammable combustibles, explosives; transport fires; fires in residential, social and cultural buildings; detection of unexploded ordnance; loss of flammable, combustible, explosive substances;

3) with the release of radiation energy - accidents at nuclear power plants, nuclear power plants for industrial and research purposes with the release or threat of release of radioactive substances; accidents with the release of radioactive substances at nuclear fuel cycle enterprises; accidents on transport and space vehicles with nuclear installations or with a cargo of radioactive substances; accidents with nuclear weapons or operation, storage or installation; loss of radioactive sources;

4) with the release of chemical energy - accidents with the release of highly toxic substances during production processing or storage; transport accidents with the release of toxic substances; the formation and spread of potent toxic substances in the course of chemical reactions that began as a result of the accident; chemical munitions accidents; loss of sources of potent toxic substances;

5) leakage of bacteriological agents: violation of the rules for the operation of water supply and sewerage facilities; violation of technology in the work of food industry enterprises; violation of the regime of work of institutions of a sanitary and epidemiological profile.

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 ... >>

sky fish 15.09.2010

Swiss inventors have created a prototype airship without motors and propellers. Inside this fish-shaped, eight-meter-long inflatable balloon, "artificial muscles" are stretched along their entire length, which contract when electrical voltage is applied to them.

Curving like a fish, the airship floats across the sky at a speed of half a meter per second.
