How to reduce the damage of laser cutting machine radiation?

The radiation caused by laser cutting machine can not be underestimated, especially the blind damage to human eyes. So how can we protect ourselves from the radiation damage of the laser cutting machine?
1. Eyes
When people first contact the laser cutting machine, they often like to stare at the cutting head. If you watch the sparks generated by cutting for a long time, your eyes will feel stinging. In addition, during the processing of the laser cutting machine, the emitted laser can make the energy highly concentrated in space and time, and focus on the retina through the refractive medium of the eye to form an image, so that the energy density on the retina is 104-105 higher than the incident energy density on the cornea; In addition, the laser has good monochromatic property and small color difference in the fundus of the eye, so that extremely low laser energy irradiation can cause damage to the cornea or retina.
2. Skin
When the laser irradiates the skin, if the energy (power) is too large, it may cause skin damage, and long-term irradiation may cause burns and scars. This kind of damage can be repaired by tissues. Although the function has decreased, it does not affect the overall functional structure. Compared with the damage to the eyes, it is much lighter, but attention should also be paid to it.
3. Respiratory system
The high temperature generated by the laser is matched with the gas to complete various processing. At the same time, it also generates a large amount of dust. Especially when processing some special metal materials, the smoke generated contains a large amount of chemical components. Dust will be suspended in the air and harmful to human body after inhalation.
How to avoid the damage caused by the fiber laser cutting machine?
1. Necessary protective equipment for laser cutting machine, wear protective glasses to prevent laser damage to human eyes. Other personnel in the work area should not look directly at the laser during cutting.
2. Operators should pay attention to eating more foods rich in vitamin AC and protein such as carrots, bean sprouts, tomatoes, lean meat and animal liver as appropriate, and often drinking green tea, because these foods can help people better maintain their eyes, so that the human body can better maintain the human body under the irradiation of the laser cutting machine.
3. There should be a matching dust removal device, try to operate in a smooth air environment, and try to wear a mask.
4. When arranging the cutting site, the site and wall of the working environment shall be painted dark to reduce radiation.
5. Do not touch the cut parts immediately to avoid scalding due to residual temperature.
