Office electrical equipment
Bring ozone electromagnetic radiation
■ Status quo: When you walk into the office building, especially the popular big office platform, you will see the most equipment, such as computers, photocopiers, printers and so on. These necessary office equipment in modern offices not only bring great convenience to our work, but also may pose a potential threat to our health.
■ Hidden danger: Generally speaking, the biggest threat of electrical equipment to health is the generation of ozone, which will consume oxygen in the air. If ventilation is not good, ozone will compete with people's lungs for limited oxygen, making air quality worse. In this "competition", people are at a disadvantage, so they are prone to dizziness and nausea. Therefore, how to get the use value of these devices while avoiding possible health threats has become the first concern of office workers.
1. Copier Copier is the office equipment that produces the largest amount of ozone in the office. This is because the current photocopiers are generally electrostatic copying, and the electrostatic voltage is very high, so it will produce a lot of ozone. If the ventilation is poor and the ozone concentration in the office environment is high, it will easily have an adverse impact on people's health.
Ozone is a gas with a strong pungent smell. Ozone can not only cause cancer, but also stimulate people's respiratory tract, causing respiratory tract irritation symptoms, such as cough and bronchitis. In addition, ozone will also threaten people's nervous system, causing dizziness, headache, nausea, decreased vision, decreased memory and other problems, undermining human immunity, easily aging people, and people's skin is also prone to dark spots. If pregnant women are exposed to high ozone concentration for a long time, fetal malformation may also occur.
2. Printers, mainly inkjet printers, pose a threat to human health. Because the ink particles ejected by the inkjet printer are very small, they are not easy to see with the naked eye, but they will float in the air. If the ventilation is not good, this inhalable particulate matter will also cause harm to people's respiratory system.
3. Computers are also necessary electrical equipment in the office now. The main pollutants produced by computers are ozone and electromagnetic radiation, as well as dust. Studies have found that computer radiation has adverse effects on pregnant women and fetuses, because too much electromagnetic radiation may affect people's fertility. The research also shows that long-term low-intensity electromagnetic radiation can cause many kinds of damage to the central nervous system, cardiovascular system, blood system, visual system and immune function of human body.
In addition, excessive electromagnetic radiation can also cause excessive tension, neurasthenia, insomnia, inattention, memory loss, slow response, headache, dizziness, dreaminess, irritability, loss of appetite, abnormal blood pressure, leukopenia and other problems. In addition, if you don't pay attention to eye care, using a computer may also reduce people's vision.
Countermeasures
For the needs of work, we can't throw computers, photocopiers and printers out of the office, but learn to get along with them.
1. Ensure the fresh air volume in the office environment and dilute harmful gases.
2. Pay attention to the cleanliness of the office environment and clean it in time.
3. Pregnant women should try to stay away from computers or computers with LCD screens. If possible, they can wear radiation protection suits.
situation
Miss Wang, 27, is an employee of a company.
My job in the company is mainly secretarial work. Therefore, I use computers more. I open it almost every day as soon as I get to class. I have to work around the computer, input files, print and copy. After a long time, especially typing on the computer for a long time, I feel numb, and my reaction to talking to people is half a beat.
Our office is a big platform, and people are so concentrated that we really bow our heads and don't look up. And people's activities are particularly large. However, because the air conditioner is used and the temperature is quite suitable, the window is rarely opened. Especially this winter, it's cold with the windows open. As a result, sometimes at the end of the day, I don't know if I am tired or bored, and I feel dizzy and have no strength after work. Moreover, if you come back from work outside, you will obviously feel that the air in the office is very turbid. ...
interior decoration
The harmful gas it brings.
★ Grounding
1. Carpets In many office buildings, there are all kinds of carpets on the ground, such as chemical fiber, pure wool or cotton. Carpet beautifies the office environment, but it is the easiest place to hide evil people and practices in the office. Gao Xudong pointed out that although many offices use vacuum cleaners to clean carpets every day, it is difficult to achieve deep cleaning, so the hygiene of carpets often fails to meet the hygiene requirements, and there will be mites, bacteria and dust inside, which is conducive to the spread of diseases.
Countermeasures: In addition to daily vacuuming, it is best to clean carpets regularly and use fungicides and disinfectants. In addition, the carpet had better be replaced regularly.
2. Marble floor In some office buildings, you can see the bright marble floor. Although it looks clean and gorgeous, the marble floor will emit radioactive substances, which is very harmful to human body.
Countermeasures: Suggest simple decoration.
★ Other interior decoration
In addition to the carpets and marble floors mentioned above, almost all the office platforms of office buildings have been renovated, and ceilings and wallpapers are also common. This will inevitably bring pollution to some decoration materials. Decoration materials, especially non-environmental protection building materials, may contain volatile gases such as formaldehyde and benzene. For example, artificial boards such as paints and floors used in decoration may contain harmful substances such as formaldehyde, toluene and xylene, and other volatile organic compounds, which are harmful to people's health. In addition, some offices work while decorating or enter the office immediately after decoration, which is not conducive to the release of harmful gases. For example, in some renovated office buildings, harmful gases are likely to enter other floors through pipelines, posing a threat to people who are working and expanding the pollution surface.
Experts pointed out that formaldehyde is a colorless and harmful gas, which was declared as a suspected carcinogen by the World Health Organization. Formaldehyde has a great influence on human nervous system, respiratory system and digestive system. It is easy to cause allergic reactions, asthma, rhinitis, pharyngitis and other diseases. Long-term exposure may also cause cancer of nasal cavity, mouth, throat, skin and digestive tract. Benzene is also a recognized carcinogen, and too high benzene concentration may lead to cancer, such as leukemia. Women who inhale benzene for a long time will suffer from many diseases. Long-term inhalation of benzene by women of childbearing age will lead to abnormal menstruation, mainly manifested as menorrhagia or disorder. In addition, benzene can also cause fetal congenital defects. When pregnant women are exposed to the mixture of toluene, xylene and benzene, the incidence of pregnancy complications such as pregnancy-induced hypertension syndrome, pregnancy vomiting and pregnancy anemia increases obviously, and even leads to abortion.
Countermeasures: If possible, try to reduce the office density, simplify the decoration and choose environmentally friendly materials. In addition, if it is a local decoration, it is best to stop using central air conditioning during decoration and seal it properly to minimize pollution.
The air is not smooth
Resulting in poor air quality.
The desks, chairs, bookcases and filing cabinets in the office are mostly wood-based panels, such as particleboard, density board, three-ply board and five-ply board, which may contain volatile organic compounds such as formaldehyde, toluene and xylene. This will affect the air quality in the office.
In addition, in most office environments, people are relatively concentrated, and some people smoke in the office, but the use environment of air conditioners is mostly closed. This makes the indoor air quality poor, oxygen is relatively insufficient, and carbon dioxide exceeds the standard. At present, most office buildings use central air conditioning, and many central air conditioners also need ventilation pipes. The pipeline is dark and humid, and it is particularly easy to breed bacteria, such as Legionella. After a long time, there will be a lot of dust, which will also cause an increase in indoor inhalable particles.
Countermeasures: 1. Open more windows. It is best to open the window first thing after work every day to naturally ventilate and improve the air quality in the office.
2. If work permits, it is best to go to a place with good ventilation or outdoor activities every once in a while, especially those who work in the basement should pay attention to this.
3. Advocate wet cleaning when cleaning, that is, use a wet mop or rag when mopping the floor, wiping the desktop and windowsill.
4. It is recommended to use the central air conditioning ventilation system, and the central air conditioning must be cleaned and maintained in accordance with national regulations.
5. For an office building with an underground garage, it is best to keep the air pressure positive, and it is best to use an axial fan in the underground garage to exhaust automobile exhaust as much as possible.
6. Put some green plants indoors.
insect pest
In addition to the above-mentioned office pollution, pests can not be ignored. Cockroaches are common pests in the office environment where electrical equipment is widely used. Cockroaches breed quickly and spread diseases easily.
Countermeasures: pay attention to cleaning and clean up the garbage in time. Regularly kill cockroaches with drugs in office buildings.
I didn't expect to see such an exquisite post today!
