Safe Operation

Introduction

Working on cutting machines can be accompanied by a number of harmful and dangerous production factors, including:

electricity;
small chips and aerosols of cutting fluid;
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 a 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 Production processes. General safety requirements; GOST 12.3.025-80 Metal cutting. security requirements, etc.

bring the saw blade to the workpiece at the beginning of cutting carefully, smoothly, without bumps;
prevent splashing of oil and coolants.

3.2. While working on the machine, it is prohibited:

work in mittens or gloves, as well as with bandaged fingers without rubber fingertips;
take and feed any objects through the working machine, tighten nuts, bolts and other connecting parts of the machine;
blow the workpiece with compressed air from a hose;
stand in the plane of disk rotation during machine operation;
support the cut end of the workpiece with your hands;
eject chips from disc segments on the go;
use local lighting with a voltage higher than 42 V;
work on a machine that is faulty and does not have the necessary guards;
work with a faulty disk (with broken segments and teeth, unsharpened, having cracks, as well as welded or drilled cracks);
be between the part and the machine when installing the part with a crane;
remove chips directly by hand;
during operation of the machine, open and remove guards and safety devices;
lean on the machine during its operation and allow others to do it;
fix the workpiece during the rotation of the disk;
during the rotation of the disk, correct the position of the tube of the cooling system;
leave keys, fixtures and other tools on a running machine.

4. Labor protection requirements in emergency situations

4.1. In the event of a breakdown of the machine, failure of the control panel, turn off the machine and inform the foreman about it.

4.2. In case of fire of rags, equipment or a fire, immediately turn off the machine, inform the administration and other workers of the workshop about the incident and proceed to eliminate the source of fire

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. ... >>

Robot Experimenter 14.08.2005

The robot, which itself builds hypotheses about the function of a particular gene in the gene set of a yeast cell and itself develops experiments that can test its hypotheses, was created at the University of Wales (Great Britain).

There are about 6000 genes in a cell of ordinary baker's yeast, and the function of 30 percent of them is not yet clear. To understand why a particular gene is needed, biologists remove it from a single cell, and then watch how this cell grows and multiplies on different nutrient media.

This is what the robot does, which contains information about yeast and their biochemistry. It mixes chemicals, creating different nutrient media with the presence of one or another substance that is not required by ordinary yeast, but is supposedly needed by mutants with one missing gene. Spilling the resulting nutrient mixtures into special flat vessels, the robot places mutant cells there and watches how they multiply.

Scientists can only accept the results of the experiment from the robot. The results of the research will be important not only for the baking industry, but also for medicine, since many yeast genes are also present in the human gene set.
