BASIC REQUIREMENTS FOR ORGANIZING SAFE OPERATION OF ELECTRICAL INSTALLATIONS. Compiled by Karpova I.I. Occupational safety teacher

The first group is certified for persons who do not have special electrical training, but have a clear understanding of the dangers of electric current and safety measures when working on the serviced area, electrical equipment, and electrical installations. Certified persons must have practical knowledge of the rules of first aid.

Electrical safety is understood as a system of organizational and technical measures to protect people from the effects of damaging factors of electric current. Electrical injury is the result of exposure of a person to electric current and electric arc.

Electric current, passing through a living organism, produces: a thermal (thermal) effect, which is expressed in burns of individual parts of the body, heating of blood vessels, blood, nerve fibers, etc.; electrolytic (biochemical) effect - expressed in the decomposition of blood and other organic liquids, causing significant disturbances in their physical and chemical compositions; biological (mechanical) effect - expressed in irritation and stimulation of living tissues of the body, accompanied by involuntary convulsive contraction of muscles (including the heart, lungs).

Electrical injuries include: electrical burns (current, contact arc, and combined); electrical signs (“tags”), metallization of skin; mechanical damage; electroophthalmia; electric shock (electric shock).

The main factors determining the outcome of the lesion are: the magnitude of current and voltage; duration of current exposure; body resistance; loop (“path”) of current; psychological readiness to strike.

According to the degree of physiological impact, the following damaging currents can be distinguished: 0.8 – 1.2 mA - threshold perceptible current (that is, the smallest current value that a person begins to feel); 10 - 16 mA - threshold non-releasing (chaining) current, when due to convulsive contraction of the hands a person cannot independently free himself from live parts; 100 mA - threshold fibrillation current; it is the calculated damaging current. It must be borne in mind that the probability of injury from such a current is 50% if its exposure lasts for at least 0.5 seconds.

Work on live parts without the use of protective equipment is only possible when the voltage is completely removed!

Factors in a person’s condition that significantly increase the likelihood of a fatal electric shock include: everything that increases the rate of the heart - fatigue, excitement, taking alcohol, drugs, certain medications, smoking, illness; anything that reduces skin resistance - sweating, cuts, drinking alcohol.

Path (“loop”) of current through the human body. When investigating electrical accidents, the first step is to determine which path the current took. A person can touch live parts (or metal non-live parts that may be energized) with a variety of parts of the body. Hence the variety of possible current paths. The following are recognized as the most likely: “right arm - legs” (20% of cases of damage); “left arm - legs” (17%); “both hands and feet” (12%); “head - legs” (5%); “hand - hand” (40%); “leg - leg” (6%).

Stepping is the voltage between two points on the ground, caused by the spreading of current in the ground, while simultaneously touching them with a person’s feet. Moreover, the wider the step, the greater the current flows through the legs. To protect against step voltage, additional protective equipment is used - dielectric boots, dielectric mats. In cases where the use of these means is not possible, you should leave the spreading area so that the distance between your feet standing on the ground is minimal - in short steps. It is also safe to move on dry boards and other dry, non-conductive objects.

Precautions when using electrical appliances and networks To do this, it is necessary to: maintain the electrical network and electrical appliances connected to it in good condition; know and always comply with the basic requirements for the design of electrical installations and precautions when using them; If you feel the effect of electric current when touching metal structures, immediately take measures to prevent people from entering the dangerous place and report this to the manager.

Wire protection You cannot use any kind of surrogates in the form of a bundle of wire (the so-called “bugs”) and the like instead of plug fuses! You cannot exclude automatic releases (“automatic devices”) and RCDs from the circuit, even if they are constantly “knocked out”! If the fuse, as well as the automatic release, blows, it should be replaced with a new one of the SAME RATING (CURRENT).

Insulation serviceability It is always necessary to remember that touching exposed live wires, as well as faulty and damaged devices, appliances, and electrical fittings, poses a great danger to life. Repairs to electrical wiring should only be carried out by qualified workers when the section of wiring being repaired is completely disconnected.

The main task of adults is to ensure the safety of children. And it doesn’t matter at all where they will be: at school or at home, in the forest or on the road, in a car or on a train. Children receive their first safety lessons at school. Presentations on the topic of safety for children should be shown in every class so that students from grades 1 to 11 know that many emergency situations can be avoided if you know how to behave.

You have received a class and become a class teacher, which means you already need to download a presentation on the topic of safety at school, at home, on the street, in transport. For a long time, this topic was considered the most difficult when planning the educational process. Children are bored sitting at their desks and listening to safety instructions. Everything changed with the advent of IT in school life. Now the safety precautions described on the presentation slides arouse the child’s interest. He not only listens, but also remembers, takes an active part in discussing situations.

Our collection includes safety presentations for all grade levels and on any topic. For kids, you can download a presentation on the topic of safety at school, when roller skating and cycling in the form of fairy tales with pictures and music. In middle classes, presentations on the rules of safe behavior in unusual situations, when hostages are taken, in the forest would be appropriate. High school students, getting acquainted with safety rules, strive to learn something new. It's time to download presentations on safety precautions and security systems that are used in the world.

Life brings more than just joy. Sometimes there are so many surprises in it, but it is presentations with safety lessons that will save someone’s child’s life when trouble comes from somewhere or will prevent a meeting with this very trouble.

Do not think that ensuring children's safety is the primary task of parents. They do not have special education, and some simply do not assume that it is necessary to talk about such topics with a child. But the teacher has the opportunity to download for free from the website any presentation on the topic of safe behavior at school, electrical safety, personal safety of children and reveal to them the little secrets of preserving their own lives.

The danger must bypass the children, but it will not touch them only when its students know it by sight. Let every presentation on such a pressing topic as safety be in demand by the teacher at the beginning of the school year, and on the eve of the holidays, and on the eve of any holiday, and not only when the school reports another accident.

In addition to this section, presentations on safe behavior can be downloaded for free in the sections Traffic Rules, Fire Safety, Terrorism, Railway.

Every school should be safe. The presentation tells how to ensure safety at school for children not only in the classroom, but also in the locker room, library, cafeteria, gym, and school grounds. It is necessary to download a presentation on the topic of safety within the school walls in order to warn children about the dangers that occur due to their carelessness or carelessness.

As soon as the third quarter ends in the spring, the teacher should download a free presentation on safety rules during spring break. It can also be used at the end of the school year to provide instruction during class or life safety lessons for primary school students on the rules of safe behavior in the summer. Free presentation on safety precautions during spring and summer holidays - happy adventures for children without injuries or accidents.

Leaving a child at home alone is always scary. A presentation for children on the topic “Home Safety” contains fascinating advice from the wise Owl, who tells how to use the elevator, how to behave if a stranger rings the doorbell or telephone. A presentation for children in grades 1, 2 or preschoolers states that your safety, child, at school and at home depends on yourself.

A 16-slide presentation for children on the topic “Road Safety” talks about the dangers encountered when entering the roadway and how they can be avoided. By following all safety rules on the road, the road to school and to friends, to the store and the library will be completely safe.

Joking with electricity never led to anything good. A presentation for children on the topic of electrical safety, talks about the rules for handling electrical appliances at school and at home. In addition, the presentation draws attention to the rules of conduct near transformer booths and power lines.

A presentation on the topic “Rules of Safe Behavior” will save children’s lives, the slides of which talk about safe behavior in the forest, when crossing the street, when an unfavorable environmental situation occurs in the region, or even when children are taken hostage by terrorists. These presentation slides, which can be downloaded for free, do not scare children, but teach basic safety rules in and out of school. Children's lives depend on the implementation of such rules. The presentation contains all the rules of safe behavior from A to Z.

A presentation on the topic “Safety rules for children” will warn our nimble and restless students from misfortunes on the roads and streets, and will answer the question of why it is necessary to follow safety rules on the train and in the car, as well as when roller skating. These topics excite children so much that each slide of a presentation on safety rules will cause a shout out among children and will be remembered for a long time.

The presentation “Safety Lesson” teaches children the rules of behavior in everyday life. They seem simple, but you need to know them, because they inform you about the risks that lead to tragedy. You can download a safety lesson with a presentation for elementary school, as the material is fascinating and contains many illustrations.
