10 main causes of electric shock in everyday life
What is electric current?
The concentrated course of charged particles in space under the influence of an electric field. That is how the term electric current is explained. What about the particles? So they can be absolutely any, for example: electrons, ions, etc. It all depends on the object in which this very particle is located (electrodes / cathodes / anodes, etc.). If we explain according to the theory of electric chains, then the cause of the electric current is the “targeted” course of charge holders in a conducting environment when exposed to an electric field.
How does electricity affect the human body?
A strong electric current, which is passed through a living organism (human, animal), may cause a burn, and can cause damage from electricity through fibrillation (when the ventricles of the heart contract not synchronously, but each “on its own”) and eventually it will to death.
But if you look at the other side of the coin, electric current is used in therapy, for resuscitation of patients (during fibrillation of the ventricles they use a defibrillator, a device that simultaneously reduces the muscles of the heart by means of electricity, and thereby making the heart beat in its “usual” rhythm), etc. D., but this is not all. Every day, starting from our birth, electricity "flows" into us. It is used by our body in the nervous system to transmit impulses from one neuron to another.
Electrical Appliance Rules
In fact, we will offer you a list of rules of what is impossible and what needs to be done when children interact with electrical devices, BUT this does not mean that as an adult you can neglect these rules! So, let's begin!
When interacting with electrical appliances DO NOT:
- Touch bare wires.
- Activate broken electrical appliances, because in which case they can cause a fire or electric shock.
- Touch the wires with wet hands (especially if they are bare).
REQUIRED:
- Remember that in no case can you pull on the wire in order to pull it out of the socket.
- When leaving home, check to see if any electrical appliance is left on.
- If you are a child, be sure to call an adult if, during plugging into an electrical outlet, you saw that the wire or the appliance itself began to smoke.
The main causes of electric shock
An electric shock can occur while a person is near the place where live parts included in the network are located. It can be described as irritation or the interaction of body tissues with electricity. In the end, this will lead to absolutely involuntary (convulsive) contractions of the human muscles.
There are a number of causes of electric shock to a person, such as: the possibility of damage when replacing a light bulb in a lamp connected to the network, the interaction of a person’s body with equipment that is connected to the network, long (uninterrupted) operation of electrical appliances, and of course people who don’t repair everything themselves depending on whether it is successful or not (in other words, "Homemade"). Let's start by listing the main causes of electric shock, and then in order we will figure out what the essence of these problems is.
The main causes of electric shock are:
- Human interactions with faulty household electrical appliances.
- Touching bare parts of the electrical installation.
- Erroneous supply of voltage to the place of work. That is why in production you need to hang out a special electrical safety signas in the picture below:
- Appearance of voltage on the equipment case, which should not be energized under normal conditions.
- Electric shock due to a faulty power line.
- Replacing the light bulb in the lamp connected to the network. People can be injured due to the fact that during the banal replacement of the bulb, they simply forget to turn off the lights. It must be remembered that before changing the bulb, the first thing to do is turn off the light.
- The interaction of the human body with equipment that is connected to the network. There were cases when people were injured from this option. Everything is simple here. When interacting with an electrical appliance (for example, a washing machine), you hold with your second hand a piece of the house that is grounded (for example, a pipe). Thus, a current will pass through your body, which will cause damage. To prevent this from happening, it is recommended make a potential equalization system.
- Long (continuous) operation of electrical appliances. In fact, cases of damage in this way are minimal. The problem is this: appliances such as a washing machine can break down after a long period of work and at least leak in the case of a washing machine. In order to avoid such incidents, just check that the devices are working properly more often. About, what to do if the washing machine is electrocuted, we told in the corresponding article.
- People who fix everything themselves. This is considered the most common problem of all, because today with the help of the Internet you can find a lot of instructions like "How to ...", even on our website in the section electronic homemade. However, the majority of people who begin to design something do not have the proper knowledge and, due to the usual carelessness, are injured or even maimed.
- Power surges can be very dangerous for you or your equipment, in the end, voltage drops can cause a fire or worse - a cause of electric shock. So how do you deal with this? Today, there are three main ways to reduce the effects of power surges, namely: Voltage regulator, uninterruptable power source Well voltage relay. These three things in life will serve you and your equipment as protection against power surges.
Finally, we recommend watching a video on the topic:
So we examined the main causes of electric shock and protective measures against this danger in everyday life. Be careful and be sure to check out rules of first aid in case of electric shock!
