Household appliances: irreplaceable helpers or a hidden threat? Household appliances - irreplaceable helpers or hidden threats
How dangerous are electrical appliances?
Under certain conditions, when using well-known equipment and devices, dangerous situations can arise for you, for your loved ones and for your home.
Such situations can arise for two reasons. In the first case, you yourself can create a dangerous situation by violating the rules for using equipment and household appliances. In another case, a dangerous situation may arise regardless of you: the electrical voltage in the network has increased sharply, the faucet is leaking, turning off the water in the bathroom, etc.
In order for you to know how to avoid the occurrence of a dangerous situation in everyday life, and if it does occur, to reduce its harmful consequences, we will look at the main everyday situations in which certain rules must be followed.
Rules for using electrical appliances.
When electric current passes through the human body, it heats up and can cause burns. Electrical burns can cause serious damage to the internal tissues of the human body. In addition, electrical shock can cause cardiac arrest or respiratory arrest.
To prevent this from happening, in everyday life it is necessary to follow a number of general rules for the safe handling of electricity:
- do not use faulty electrical appliances, never leave a switched-on electrical appliance unattended;
- do not plug several electrical appliances into one outlet;
- follow the order of connecting an electrical appliance to the network: first connect the cord to the device, and then connect the cord to the network.
Switching off the device is done in the reverse order;
- do not touch the switched on electrical appliance with wet hands;
- remember: you cannot use electrical devices while in water;
- Immediately inform your parents or elders about detected malfunctions in electrical appliances, exposed or poorly insulated wires.
Remember!
Do not extinguish burning electrical devices connected to the electrical network with water.
A computer is a very useful and sometimes necessary thing. However, improper handling can be harmful to health.
Rules for working at the computer:
- make sure that the position of the monitor corresponds to the direction of view, the middle of the monitor screen is located on a horizontal line drawn at eye level or 10-20° below;
- do not work in a dark or semi-dark room.
- in accordance with established standards, the continuous duration of a student’s work at a computer should not exceed 25 minutes;
- After each long session on the computer, it is recommended to perform certain physical exercises.
Household gas and its properties
Perhaps, with your parents' permission, you use a gas stove for cooking. To use domestic gas, a gas pipeline is installed in the apartment and a gas stove or gas water heater is installed. You constantly use various electrical appliances: iron, lamp, TV, radio equipment. For this purpose, there is electrical wiring, and in certain places there are electrical sockets and room lighting switches.
Currently, household gas is widely used in everyday life. It can be used in gas stoves for cooking and in gas water heaters for heating water.
Gas used for domestic purposes can be of two types: liquefied gas in cylinders and city main gas.
Household gas has neither color nor odor, but in order to detect its leak, special substances that have a specific odor are added to it.
Rules for safe handling of gas appliances
A gas leak can lead to human poisoning and explosion of the premises. To prevent this, you must follow safety rules when using household gas. We list the main ones:
- to light a gas burner, first bring a lit match, and then smoothly and carefully open the gas tap.
- do not leave switched on gas burners unattended.
- make sure that the liquid heated on the gas stove does not flood the burner flame.
- if you notice an extinguished burner, do not try to light it again - this may lead to an explosion. Turn off the gas tap, open the windows and ventilate the kitchen properly. Report the incident to an adult.
The most ordinary gas stove in the kitchen can become a source of many troubles if you do not take certain precautions: after all, when burning, the gas releases various toxic substances into the air.
Therefore, while the gas is burning, keep the window or transom open, and be sure to close the kitchen door.
Make sure that the flame above the burner is blue, without any admixture of yellow or red.
Try to place teapots or pots with a wide bottom on a high stand, otherwise the access of air to the burner is reduced and the gas does not burn completely.
Gas is convenient and safe only if you handle gas appliances skillfully and correctly.
You must always remember and follow the rules for using it:
Do not leave switched on gas appliances unattended;
- do not allow preschool children to use gas appliances, as well as persons who do not know the rules for handling these appliances.
Keep gas appliances clean and in good working order.
During the period of soil freezing, the possibility of rupture of underground gas pipelines cannot be ruled out. Gas coming out of damaged areas can spread over long distances and penetrate into basements and first floors of even non-gas-free buildings. When going down into the basements, do not use open flames or electrical switches without making sure that there is no smell of gas.
If you smell gas, immediately report it by calling 04. Before the emergency vehicle arrives, take safety measures: do not allow open fire and, if possible, ventilate the room.
Be careful and careful!
Don't neglect safety measures. Save gas.
Do not allow gas burners to operate for long periods of time without utensils.
Adjust the flame of gas burners. Reduce the gas to the minimum flame size after the water in the pan boils.
If you have gas burners of different capacities, use the larger burner only when necessary.
Prevent scale formation in kettles. Boiling water for a long time increases scale deposits.
Cover dishes with lids while cooking; this technique allows you to save 15% of gas.
What to do if there is a gas leak?
Turn off the gas burners. Turn off the gas valve.
Avoid any actions that cause sparks and increase the room temperature. Do not touch electrical switches, this may also cause a spark. Ensure intensive ventilation of the room by opening all windows. Remove everyone present. Stop the gas supply if possible. Call the technician on 04.
Devices containing mercury
Household appliances containing mercury:
- fluorescent lamps (these are gas-discharge tubes containing inert gases and mercury vapor). All such lamps contain mercury - from 40 to 70 mg.
- mercury thermometers;
- instruments for measuring pressure (pressure gauges).
Thermometers are found in every home; they are made of glass and easily break if dropped. In this case, mercury balls easily roll into floor cracks or are sucked into the carpet.
Fluorescent lamps are often thrown together with household waste into trash cans, where they break easily and release mercury vapor into the surrounding atmosphere.
Children and teenagers who break such lamps out of hooliganism usually do not even suspect what gets into their lungs.
Poisonous properties of mercury
Mercury is a heavy liquid metal, silvery in color. It has a highly convex surface. In small quantities it collects into very mobile balls. It easily penetrates into the cracks of floors, furniture, walls, is absorbed by porous bodies, including wood, paper, fabric, plaster, remaining there for a long time, and is a source of indoor air pollution. Mercury freezes at -38.9°C. Mercury evaporates at room and even zero temperatures, mercury vapor is colorless and odorless.
Mercury and its compounds can enter the body through the lungs, gastrointestinal tract, and skin.
Mercury vapor and its compounds are very poisonous. Chronic poisoning with mercury and its compounds results in a metallic taste in the mouth, loose gums, severe salivation, excitability, and weakened memory. The danger of such poisoning exists in all rooms where mercury is in contact with air. The smallest drops of spilled mercury that have clogged up under baseboards, linoleum, furniture, and in floor crevices are especially dangerous. The total surface of small mercury balls is large, and evaporation is more intense.
Children, a few hours after they start inhaling mercury vapor, may develop severe pneumonia (pneumonia) - cough, shortness of breath, and fever. In case of severe poisoning, pulmonary edema is possible (this is a deadly condition). Possible diarrhea (diarrhea), drowsiness, followed by nervous excitement.
Actions in the event of a mercury spill
The smallest drops of spilled mercury that have clogged up under baseboards, linoleum, furniture, and in floor crevices are especially dangerous. The total surface of small mercury balls is large, and evaporation is more intense.
If the device breaks and mercury gets on the floor, you should carefully collect all visible balls in a hermetically sealed bottle, wipe the area of the mercury spill with a rag moistened with a solution of potassium permanganate, and then contact a specialized organization, which will check whether there are any mercury vapors left in the apartment, and if there are any left, it will help to remove them.
It is better not to use mercury fluorescent lamps (fluorescent lamps) in residential premises at all. Remember that one mercury fluorescent lamp, broken in a medium-sized room, can create a concentration of mercury vapor in the air above the permissible limit.
We live in peace with you electromagnetic fields, our children, argue about harm every moment, and you ask, how to protect yourself?
Our house has almost the entire set of electrical appliances. They help us by saving time and energy. As they say, time is money, it makes household chores easier, and gives access to information from anywhere.
They are necessary in any case, no matter how you look at them. It is now possible to pay more attention to children than was the case half a century ago. Making our daily life easier. You may ask how safe they are in our lives. How will their electromagnetic radiation threaten us?
Will a child stay in a house with many electrical appliances and wires? The most important question is probably how to protect your baby and yourself?
Radio waves are the most popular in their class. Surrounding us all everywhere, in the same house, work. They are emitted by the same electrical appliances and electrical installations. If you have ever seen high-voltage lines along the roads, we watch TV, and this signal is emitted by television towers, we listen to the radio, it is emitted by radio towers. You talk on mobile phones, these are cell stations. Connections Even the same wiring that is cut into the walls of our houses. You've probably noticed that the irons you use to iron your clothes are the refrigerators you use to store food. And the radiotelephones on which we talk while walking around the room, they are not the largest and largest emitters of electromagnetic waves.
They are constantly nearby our little toddlers. They are exposed to them around the clock; during the day, of course, they have a greater influence, but at night they have the least effect. What do you think threatens us and our children? Unfortunately, scientists have not yet fully studied the harm, thus we cannot know definitively whether they are harmful or not.
Laboratories in which multiple studies have been carried out for more than fifteen years have been studying this issue.
There are no final results of data on harm or refuting that electromagnetic waves are not harmful.
But, some opinions have already been made public. They wrote that some of the waves can be reflected from the human body, and the rest can be absorbed, causing heating of internal organs.
Proteins that in the body can sense changes in temperature.
The same molecular vibrations occurs due to electromagnetic radiation, and provoke complex nervous reactions. And no one in our time can predict or predict what this or that change in the body will lead to. Because, the study of these phenomena is studied and adjusted to each other every time.
There are also moments when taking the same device separately, it does not exceed the maximum limits of the Euro standard. But what happens when there are a lot of electrical appliances in the house? Together they emit a lot of electromagnetic radiation, making it difficult to calculate their total amount of harm to the human body.
Even if you measure radiation near your bed, you will have to call a specialist who can measure radiation with special instruments. It will be impossible to do this alone with virtually no knowledge. Experts and doctors advise placing as few electrical appliances as possible in the room and in the house as a whole.
Our favorite TV remains, probably, one of the largest radiation sources in particular. Even LCD monitors, which are quote-unquote safe, need to be placed from the place where you lie, from a meter to two meters. And turn on your TV as little as possible.
Thus, you will save your eyesight and nerves from watching the news.
Computers have become much safer these days, five or ten years ago. But this does not mean that you can put it in your room and work on it night and day later. If you have Wi-Fi access points, be sure to turn them off from the network.
Your refrigerator, which stores food, can emit various radiations. Namely, there is one very dangerous element such as “no frost”. Such refrigerators should be located at a distance of one and a half meters from eating areas. When from ordinary ones, half a meter is enough.
As for mobile phones, we can say this: They (mobile phones) have a certain place in our lives. During pregnancy, when the mother carries the phone in her pocket or talks on it, and at birth the child still experiences the effects of the phone. Doctors and doctors do not advise pregnant girls or women to talk on the phone while breastfeeding. And leaving it near a child’s bed is also unacceptable.
Remember, the most radiation occurs when calling a subscriber.
And as a reminder: children's bodies feel various electromagnetic radiation most of all. It’s better not to expose their so unprotected body anyway.
We wish you good luck and a safe environment in your home.
In our age of high technology, we are daily exposed to various electromagnetic radiation, which negatively affects our health. But we cannot refuse all the technical innovations that make our lives so much easier.
In order to somehow minimize the impact of electromagnetic field radiation on our body, we should, if possible, reduce the number of sources, reduce the time of their exposure, and stay at a safe distance when operating devices.
What devices with electromagnetic radiation are dangerous and how dangerous?
At what distance should you be from household appliances while they are operating?
1. Microwave - at least 30 cm. The most dangerous device. The most emitting place is in the lower right corner of the door.
2. Vacuum cleaner - at least 60 cm;
3. Electric stove - at least 30 cm. Do not press against it;
4. Electric kettle - at least 30 cm;
5. Washing machine - 60 centimeters;
6. Dishwasher - 40 centimeters;
7. TV - 1.5 m. For large TVs over 2 meters;
8. A table lamp is equal to a TV;
9. Electric iron - 20 centimeters. Dangerous when heated - try to distance yourself from it at this time;
10. Air conditioning - 1.5 m;
11. Computer - 80 centimeters from the screen;
12. Refrigerator - 30 cm. No-frost - further than 50 centimeters;
13. Radiotelephone and its wiring in the wall or along the wall. Talk on the radiotelephone as little as possible. Buy the most secure models;
14. Mobile phone - do not carry it close to your body and do not place it closer than 50 centimeters next to you at home or at work.
Properly installed electrical wiring does not pose a danger to residents. Avoid using extension cords if possible and do not bundle wires into rings. Do not overload sockets with tees and connections. You will have less headaches.
Remember - the lower the power of the equipment, the safer it is.
Electrical appliances also emit electromagnetic waves in standby mode. Try to keep the following switched off if possible: stereos, TVs, fans, microwaves and others.
Don't buy unnecessary electrical appliances. Do not turn on several powerful electrical appliances at once; you should not create an “electromagnetic storm” in the house. Use household appliances separately, for example, when working with a vacuum cleaner, turn off the TV.
In addition, household appliances contain the following dangers:
- Reproduction of bacteria in the microwave, refrigerator, household waste shredder, oven. All equipment must be washed promptly.
- The vacuum cleaner needs to be cleaned on time - dust mites multiply in it.
- Computer monitors and TVs cause eye fatigue - take several breaks from working and watching TV.
- Always remember that a glass-ceramic hob without a residual heat indicator may burn you.
- The washing machine and dishwasher can flood the neighbors below if the hoses break. Close the water supply taps. They can also give you an electric shock on a wet floor if the wiring is poor.
At first glance, it may seem that while at home, a person is completely safe from external harmful factors that can harm his health. But, being surrounded by household appliances, a person exposes himself to a greater risk than staying for a long time, for example, near a chemical plant or power line. Electromagnetic fields from the technology around us (TVs, refrigerators, microwaves, computers, etc.) negatively affect the central nervous, cardiovascular and reproductive systems. Such factors can cause cancer and even infertility. But since it is difficult, and sometimes even impossible, to refuse to use technology, you should know some rules that will help reduce the degree of harmful effects on the body.
One of the dangerous home appliances is the refrigerator. Some models are capable of emitting electromagnetic waves within a radius of up to 1.5-2 m, and walls are not a hindrance for them. Therefore, you should limit the time you spend near the refrigerator, and also do not place the bed against the wall, behind which this equipment is immediately located.
It is believed that a microwave oven (or microwave oven) is the most dangerous household appliance. But we hasten to note that modern technologies used to create this equipment do not allow electromagnetic radiation to spread far from the microwave oven body. Thus, a microwave oven is sometimes safer than a refrigerator. But you still shouldn’t be in relative proximity to the body when heating food.
The degree of harmful effects of a running washing machine is almost the same as that of a running refrigerator. For this reason, when washing, visit the bathroom where the washing machine is installed as little as possible and do not stay there for a long time.
You should definitely mention the TV and computer, without which it is now difficult to imagine the interior of the house. It is not recommended to watch a faulty TV that “ripples” or distorts colors - it can be very straining on the eyes. It’s better to look into your computer for a minute by entering http://rembitteh.ru/uslugi/remont-televizorov/ in your browser - here, on the website of the RemBytTech workshop you will find excellent TV repair specialists who will come to your home and Your TV will be repaired in no time. The newer the equipment model, the safer it is. Remember that TV should be viewed at a distance of at least 1.5-2 m, and a computer - 40-60 cm. Do not install equipment near the bed, especially at its head. Ventilate the room often when working on a computer. Try not to work on it at night, or watch TV in complete darkness, which is quite harmful to the eyes.
One of the most dangerous household appliances is a hair dryer, the electromagnetic radiation of which exceeds the norm tens of times. Its use is especially dangerous because the device is located near the head during use. The only advice that can be given in this situation is to use a hairdryer as little as possible (only if necessary).
All the best. Take care of your health.
We live in a time when electrical devices that emit electromagnetic radiation that is dangerous to humans surround us everywhere. In this review, we will identify the five most unsafe devices and appliances that can be found in every kitchen.
Energy-saving lamps.
These wonderful, economical light bulbs hide many unpleasant nuances. In addition to the fact that they contain mercury inside, and therefore the lamps cannot be thrown into a regular trash bin, they are also sources of ultraviolet and electromagnetic radiation. It is not recommended to be closer than one meter from the source of such light.

Microwave.
In the process of heating food, a microwave oven distributes powerful electromagnetic radiation in the microwave range around. Within a radius of 1 meter from a working oven, it is 10-20 times higher than the norm, so every time you start the microwave, you should leave the kitchen for a while.

Mobile phone.
Everyone has heard about the dangers of this device. Scientists have proven that during prolonged communication, the temperature in the ear area rises by 2-2.5 degrees, and this can harm brain cells. In addition, if at the beginning of a conversation the electromagnetic radiation increases slightly, then after 10 minutes it already becomes dangerous.

TV.
Many people still have old-style CRT televisions in their kitchens. Unlike new-fangled plasma panels, units with cathode ray tubes emit powerful electromagnetic radiation, and you should not get closer than one and a half meters to such colossuses. As for modern TVs, their radiation is lower and at a distance of more than 50 cm from the screen, you will be safe.
Sockets, extension cords and power supplies.
Sockets and extension cords, of course, also create an electromagnetic field, but a relatively weak one. However, if a powerful working device is stuck into them, the picture changes. For example, when you plug in a microwave oven, it emits a field that is 20 times higher than the standard one.
It is also worth noting that power supplies and chargers also emit electromagnetic radiation within a radius of 1 meter.
