no more than 2,0 g/m when performing hot work without the presence of workers inside the tank.

2.9. Carrying out hot work both inside and outside the tanks is allowed only after their appropriate preparation, if there is a completed act on the readiness to carry out repair of the tank with hot work.

2.10. When carrying out hot work, it is prohibited to use overalls with traces of oil, gasoline, kerosene and other combustible liquids.

It is forbidden to perform welding and flame cutting without overalls, goggles, special shields.

3. Labor protection requirements during work

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. ... >>

Space weather threatens self-driving cars 28.03.2018

Scientists say driverless vehicles, if designed too tightly tied to GNSS, could be severely damaged by powerful space weather events and not function as they should.

Scott McIntosh, director of the High Altitude Observatory at the National Center for Atmospheric Research in Boulder, Colorado, is warning engineers to prepare driverless cars for changes in solar activity. If these machines rely heavily on satellite navigation, they won't be able to do so if a solar storm destroys communications. Cars will have to pull over to the side of the road and wait for communication to re-establish.

GNSS disruptions can also cause magnetic particles to escape from coronal holes.

At the same time, artificial intelligence experts argue that machines are made with redundant capabilities, which can help them even with poor connectivity.

"With very detailed measurements like lane changes and bike lanes, you won't have time to take all that data, send it to the cloud, and get it back," says Danny Shapiro, director of Nvidia's automotive division. ask what is the closest route to Starbucks."
