The harm of copier dust to people, many offices will use copiers, so do you know the harm of copier dust to people? Let's take a look at the harm of copier dust to people with me. I hope it will help you.
The harm of copier dust to people 1 The harm of copier to people mainly comes from three aspects:
1 ozone of copier. (Gas harmful to human body)
Ozone strongly stimulates human respiratory tract, causing sore throat, chest tightness and cough, bronchitis and emphysema; Ozone can cause people's neurotoxicity, dizziness, headache, vision loss and memory loss;
Ozone can destroy vitamin E in human skin, leading to wrinkles and dark spots on human skin. Ozone can also destroy human immune function, induce lymphocyte chromosome lesions and accelerate aging.
2 from carbon powder (serious harm to human respiratory tract and lungs, be careful of the possibility of pneumoconiosis when it is serious)
A part of the toner of the copier will escape at high temperature and high speed, producing a certain amount of dust. The organic waste gas produced by toner heating is a strong carcinogen, which will cause various cancers and cardiovascular diseases.
Due to the use of polymer materials for development and fixing, a small amount of harmful organic gases (such as styrene) will be produced, which is also harmful to human body. These harmful substances inhaled by people will remain in the human body forever and cannot be ruled out. Long-term exposure can cause nervous system symptoms such as xerostomia, chest tightness, cough, bronchitis, toxic pulmonary edema, headache, dizziness and nausea.
Exposure lamp radiation (long-term radiation can cause hair loss, eye discomfort and other symptoms)
Exposure will emit ultraviolet light waves, which is harmful to radiation. Radiation pollution will affect the human circulatory system, immunity, reproduction and metabolism.
What we need to do is to take protective measures. Plants such as cactus, cactus, cactus finger and ruler can prevent radiation, absorb carbon dioxide and release oxygen.
This plant is placed next to the computer, which can effectively reduce radiation. The radiation of the computer will be absorbed by them, and it is beneficial to the growth of these plants, which is of great help to people who work near the computer for a long time and have high radiation in the working environment.
The harm of copier dust to people 2 1, ozone
Because of high voltage discharge, the copier will produce a certain concentration of ozone and odor. Ozone is a highly oxidizing gas, which reacts with nitrogen in the air to generate nitrogen oxides. This gas has a strong stimulating effect on human respiratory tract. If the operator inhales a lot of ozone for a long time, it will cause symptoms such as dry mouth and cough. If ozone and nitrogen-containing compounds stay in the lungs for a long time, they will also induce toxic emphysema and cause nervous system diseases.
2. Dust
When the copier is working, it will produce an invisible dust, which contains a lot of toner and carrier (an iron powder). Inhaling this dust for a long time will damage the lungs. The medical profession calls this disease ferrosilicosis.
Step 3 copy paper
At present, copy paper, especially high-grade copy paper, contains phenolic resin compounds, which are quite toxic. Long-term contact can lead to toxic reactions, such as redness of the skin, itching all over the body, sore throat and so on. This reaction can be naturally improved and recovered after being separated from the environment.
4. Strong light
When the copier is working, the strong light generated by the exposure lamp is harmful to the eyes. Long-term exposure to this strong light will reduce your vision.
The harm of copier dust to people. Radiation theory
It is said on the Internet that the radiation of photocopiers is particularly high, and long-term contact may cause fetal malformation.
This statement is groundless.
First of all, regarding the radiation safety of all kinds of electronic equipment, the state has relevant standards, and commodities must pass relevant national tests when they are listed.
One more thing, the radiation dose of mobile phones is many times higher than that of photocopiers and printers.
If you are worried about radiation effects, you might as well play less mobile phones.
Second, PM2.5
Laser copiers and printers will all involve dust pollution.
Similarly, if you use original consumables, or consumables produced by big brands that meet national standards, there is no problem.
But many companies or individuals, in order to save costs, add powder to the selenium drum for the second time.
Every time you add powder and clean the inside of the printer, there may be less dust pollution.
If you don't clean it, you will find that the inside of the printer is full of toner, and when you pull it out, the toner cartridges are leaking everywhere.
Therefore, it is recommended that you still use original or big brand compatible consumables to reduce secondary powder addition.
Third, harmful gases.
The composition of toner generally contains chemical components such as resin and paraffin, which will produce some harmful gases during fixing and heating.
Just like dust pollution, as long as you use the original factory or big brand compatible consumables and the products meet the relevant national standards, they are all safe.
However, the safety of toner produced by small factories is not guaranteed. You don't know whether the harmful components in toner will exceed the standard in order to ensure the printing blackness.
Fourth, light pollution.
In order to ensure the effect of copying and scanning, the scanning unit emits white light or green light, which is more dazzling. This kind of light pollution can be avoided.
Generally speaking, as long as the cover of the original is covered, the light of the scanning unit cannot be seen.
When copying or scanning thick documents or books, you can cover the light leakage with copy paper and other things.
Or when copying or scanning, look at other places when the light leaks to avoid direct light.
Verb (abbreviation for verb) ozone pollution
Generally, only large photocopiers will have ozone pollution.
When the copier works, it will charge the photosensitive imaging unit with high voltage.
In the process of charging, the air will be ionized and ozone will be produced.
In terms of equipment, manufacturers will take measures to absorb ozone, generally using activated carbon adsorption.
The adsorption of activated carbon will gradually decrease with the increase of time. Generally, it needs to be replaced when counting 15000.
