Rescue operations at chemical facilities. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

Rescue work should begin immediately after the decision to carry out urgent work; be carried out using personal protective equipment for respiratory organs and skin, corresponding to the nature of the chemical situation, continuously day and night in any weather, in compliance with the mode of activity of rescuers appropriate to the situation until the work is completed. Pre-conducted reconnaissance of the emergency facility and the contamination zone, the extent and boundaries of the contamination zone, clarification of the state of the emergency facility, determination of the type of emergency (ES).

When carrying out rescue operations medical assistance is provided to the injured, they are evacuated to medical centers; localization, suppression or reduction to the minimum possible level of impact of damaging factors arising during an accident is carried out. At the same time, search and rescue operations are carried out in the contaminated zone by a continuous visual inspection of the territory, buildings, structures, workshops, vehicles and other places where people could be at the time of the accident, as well as by interviewing eyewitnesses and using special devices in case of destruction and blockages .

Rescue work in the contaminated zone is being carried out with the obligatory use of personal protective equipment for the skin and respiratory organs.

When rescuing the injured at chemically hazardous facilities are taken into account the nature, severity of the lesion, the location of the victim and the release of victims under the rubble of destroyed buildings and technological systems, as well as in damaged blocked premises; emergency termination of exposure to hazardous chemicals (OHS) on the body through the use of personal protective equipment and evacuation from the contaminated area; providing first aid to victims; evacuation of the injured to medical centers and institutions for the provision of medical care and further treatment.

Held localization of the emergency and the focus of the lesion by cessation of releases of OHV; creation of ascending heat flows in the direction of movement of the OHV cloud; dispersion and displacement of the OHV cloud by the gas-air flow; restrictions on the area of the strait and the intensity of OHV evaporation; collection (pumping) of OHV into reserve tanks; cooling the OHV strait with solid carbon dioxide or neutralizing substances; backfilling of the strait with bulk substances; thickening of the strait with special compounds, followed by neutralization and removal; burning the strait.

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 ... >>

Health from a young age 17.04.2002

According to a survey conducted in the United States, Internet pages devoted to health and a healthy lifestyle are very popular among American youth. In general, young people are more interested in health issues on the Internet than adults.

Obtaining medical, physiological and hygiene information from the Internet is no less popular among the 1209 young people aged 15 to 24 surveyed than downloading music or online games, and more popular than shopping in online stores.

Half of those surveyed have at one time or another consulted the Internet about specific diseases or medical problems, and 40% do so at least once a month. They are especially interested in acute issues for young people - contraceptives, prevention of AIDS and other venereal diseases. About 25% of those interested in medical sites are looking for information on the fight against obesity, psychiatric problems, drugs, alcohol and violence.

Many teenagers are embarrassed to address their parents, teachers or doctors with medical and physiological questions, and the impersonality of the Internet frees them from shyness.
