Table No. 1

2. Labor protection requirements before starting work

2.1. The machine must be used in accordance with its intended use.

2.2. Before starting work, you need to check:

• tightening of threaded connections;
• reliable fastening of the cartridge and drill;
• no damage to the cable insulation;
• serviceability of the plug;
• the general condition of the insulation by running the electric drill idle for one minute;
• checking that the mains voltage corresponds to the machine engine voltage indicated on the consumer labeling plate;
• checking the operation of the switch.

2.3. If the following malfunctions are detected, the machine must not be operated:

• damage to the plug, cable or its protective tube;
• fuzzy operation of the switch;
• sparking brushes on the collector, accompanied by the appearance of a circular fire on its surface;
• the appearance of smoke or smell characteristic of burning insulation;
• damage to the working tool;
• breakage or appearance of cracks on body parts, handle;
• leakage of gearbox lubricant from the gearbox or ventilation ducts;
• the appearance of a knock.

3. Labor protection requirements during work

3.1. During work it is forbidden:

• ground the car
• operate the machine from ladders;
• operate the machine in an explosive or chemically active environment that destroys metals and insulation, under conditions of exposure to drops and splashes, as well as in open areas during rain or snowfall;
• leave unattended the machine connected to the power supply network;
• pull and twist the cable, subject it to stress.

3.2. Before starting work, the operator must ensure that clothing and other foreign objects do not come into contact with moving parts of the machine.

3.3. The surface to be treated must be cleaned of foreign objects.

3.4. The workpiece must be securely fastened in clamps or vise.

3.5. Before turning on the machine, make sure that the key is removed from the chuck.

3.6. During operation, it is necessary to monitor the heating of the machine to avoid overheating and failure of the electric motor.

3.7. Protective goggles must be worn when working with an electric drill.

3.8. The machine must be disconnected from the mains using a plug (with the switch first disconnected):

• when adjusting or changing the working tool;
• installation of nozzles;
• when moving a machine from one workplace to another;
• during a break in work;
• upon completion of work.

3.9. Drilling holes in the walls where electrical wiring is located should be done after disconnecting these wires from the power source and taking measures against its erroneous supply.

4. Labor protection requirements at the end of work

4.1. After finishing work, the machine must be cleaned of dust and dirt.

4.2. The machine body and cable must be inspected for damage. If defects are found, eliminate them or report them to the person responsible for storage.

4.3. To deposit the machine, the machine must be stored in a dry place.

5. Labor protection requirements in emergency situations

5.1. The machine must be turned off by the switch in the event of a sudden stop (due to loss of voltage in the network, jamming of moving parts, detection of extraneous noise).

5.2. When a person gets under voltage, it is necessary to use the First Aid Rules, having previously freed the victim from the action of electric current.

5.3. At voltages up to 1000 V, a rope, stick, board or some other dry object should be used to separate the victim from live parts or wires. You can pull the victim by the clothes, by the legs, avoiding touching the clothes, shoes of the victim without good hand insulation (put on dielectric gloves, wrap a hand with a scarf, pull a jacket sleeve over your hand). If an electric current passes into the ground through the victim and he convulsively squeezes the wire in his hand, then it is easier to interrupt the action of the current by separating the victim from the ground. You can cut the wire with an ax with a dry wooden handle or make a break using a tool with insulating handles.

5.4. When providing first aid, it is first necessary to assess the condition of the victim. If the victim has no consciousness, no breathing, no pulse, the skin is bluish, and the pupils are dilated, you should immediately begin to restore the vital functions of the body by performing artificial respiration and external cardiac massage.

If one person is providing assistance, he is located on the side of the victim and, bending over, makes two quick energetic blows (using the “mouth to mouth” or “mouth to nose” method). Then he unbends, places the palm of one hand on the lower half of the sternum, stepping back two fingers higher from its lower edge, he places the palm of the second hand on top of the first and presses, helping by tilting his body. If one person revives, then for every two deep breaths he makes 15 pressures on the sternum. When two people participate in resuscitation, the ratio “breathing - massage” is 1:5, i.e. after one deep insufflation, five compressions are applied to the chest. Artificial respiration and external cardiac massage must be carried out until the recovery of stable independent breathing and cardiac activity in the victim or until he is transferred to medical personnel.

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. ... >>

Random news from the Archive Waste sorting machines 17.07.2006 The English company "Kinetic" has created an automatic line for sorting household waste. Waste coming through the conveyor is inspected in turn by sensors and analyzers: wide range spectrometers, photometers, metal detectors, video cameras and other devices. Many of the sensors used here were originally developed for the military as target detection and acquisition sensors in fighters and tanks. The data is sent to the computer. A special recognition program allows him to decide which category of garbage this item belongs to, and a jet of compressed air dumps it into the appropriate container. The system can recognize paper and plastic bags for drinks, magnetic and non-magnetic metals, glass and plastic. The automatic line can process 36 tons of garbage per year. Now sorting is done manually, and in England 23% of all municipal solid waste is sorted and somehow disposed of. The task was set to bring this share to at least 2010% by 30.
