Zones of influence of negative factors. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

The danger zone has externally defined, spatial areas of manifestation and is characterized by an increase in the risk of an accident. There are the following zones of influence of negative factors:

1) areas for the processing of bulk materials, areas for knockout and cleaning of castings and plasma processing, processing of plastics, fiberglass and other brittle materials, areas for crushing materials, etc.;

2) vibration platforms, vehicles and construction tools, as well as vibration tools, control levers of transport vehicles, as well as areas around them;

3) areas near impact process equipment, devices for testing gases, vehicles, power machines;

4) zones near ultrasonic generators, flaw detectors;

5) areas near electrical equipment at direct current, areas near power lines, high-frequency transformers and induction drying, electric lamp generators, television screens, displays, antennas, magnets;

6) heated surfaces, molten substances, flame radiation;

7) lasers, reflected laser radiation;

8) nuclear fuel;

9) electrical networks, electrical installations, distributors, transformers, equipment with electric drive, etc.;

10) areas of movement of ground transport, conveyors, underground mechanisms, moving parts of machine tools, tools, gears;

11) areas near high pressure systems, containers with compressed gases, pipelines, pneumatic and hydraulic installations;

12) construction and assembly areas of work, maintenance of machines and installations;

13) zones of leakage of toxic gases and vapors from leaking equipment, evaporation from open containers and spills, emissions of substances during depressurization of equipment, spray painting, drying of painted surfaces;

14) welding zone and plasma treatment of materials containing chromium and manganese, pouring and transportation of dispersed materials;

15) galvanic production, container filling, liquid spraying, etc.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy.

This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

artificial snowfall 27.12.2018

American scientists have learned to please the inhabitants of the United States with snow, which is called on Christmas Eve.

Colorado State professor Barbara Jefferies claims that through a process called cloud seeding, scientists can artificially create snow. Cloud seeding programs currently exist in at least nine states in the Western United States and in 50 countries around the world, including Australia, India, and Saudi Arabia. While weather control may seem like science fiction, the technology has been around for decades.

Scientists in a laboratory experiment found that dry ice (solid carbon dioxide) causes moisture to crystallize. Then, with the help of aircraft, dry ice granules fall into the clouds and initiate artificial snowfall.
