Do photomachine influen to the health?

People who contact photocopiers for a long time are at risk of respiratory diseases such as coughing, dry throat, difficulty breathing. At a higher level, neurological diseases such as headaches, dizziness, amblyopia and immunity will appear.

According to Prof. Le Huy Ba, Center for Ecology and Environment, photocopiers are used based on the basic principle: taking advantage of extremely high voltage impulse to discharge electricity, taking advantage of light to form a closed printing section to make photo document. When using the machine, high-pressure mercury lamps or sparks (containing a large amount of ultraviolet light) have the effect of converting oxygen in the air into ozone .

According to published research results, human body's response to ozone is very sensitive . For example, when working in an environment with an ozone concentration of 10mg / m3 or more, if there is no protection, the lungs will have a large amount of ozone and lead to pneumonia. Particularly for those who contact photocopiers for a long time, there is a risk of respiratory diseases such as coughing, dry throat, difficulty breathing. At higher levels, neurological diseases such as headaches, dizziness, amblyopia and immunity will appear.

Not to mention the photocopies of photocopiers (water level, toner powder) also have significant harm to health. For example, the squid is produced from special black coal. The aromatic carbon oxide in black coal not only changes the structure of normal chromosome cells but can also cause cancer. The water level is made from powdered ink mixed with carbon oxide solution. This solution is easy to boil at low temperatures, easily evaporates, and if it is not well ventilated in the room, black coal dust clinging to the room increases the risk of causing illness for people working with the machine.

To reduce the harmful effects of photocopiers, the person directly standing in the camera should avoid looking at the light emitted from the machine, cover the machine before operating , this way will help limit the release of ozone outside. Next, pay attention to the location of the machine, do not place many copiers too close together in a closed office. Machine reservations need to be clear, if there is natural wind and sunlight, the better. To ensure health, the operator should wear a mask when operating the machine, avoiding continuous shooting. Standing for about an hour, you should stop for 5-10 minutes. In addition, the ink should choose a less toxic ingredient such as lead or persistent organic matter (POP).
