Safe Operation

1. Introduction

Metal turning may be accompanied by the presence of a number of harmful and dangerous production factors, which include:

electricity;
small chips and aerosols of cutting fluid;
flying pieces of metal;
high surface temperature of workpieces and tools;
increased level of vibration;
moving machines and mechanisms, moving products, blanks, materials;
insufficient illumination of the working area, the presence of direct and reflected brilliance, increased pulsation of the light flux.

When developing this Standard Instruction, the following labor safety system standards were used: GOST 12.0.003-74 "Hazardous and harmful production factors. Classification", GOST 12.1.004-91 "Fire safety. General requirements", GOST 12.3.002-75 "Processes production. General safety requirements", GOST 12.3.025-80 "Metal cutting. Safety requirements", etc.

When performing work in accordance with their qualifications, turners are required to comply with the safety requirements set out in this Standard Instruction.

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. ... >>
