The main harm of laser to human body is eyes and skin. Laser irradiation of any part of the human body will cause burns.
Especially long time laser processing and observation will seriously damage the retina of the eyes, so operators must strictly wear laser protective glasses! It is forbidden to operate and observe the equipment with naked eyes! Avoid exposing any part of the body to the light path of the laser equipment in operation to avoid damage to the eyes caused by the laser.
Eye and skin protection: In the process of laser processing, CO2, YAG and fiber lasers are usually used. Different types of lasers cause different injuries to the human body. The wavelength of YAG and fiber laser has a high transmittance to the eyes, causing greater damage to the eyes and possibly damaging the retina of the eyes. The main harm of CO2 laser is to burn the cornea of the eye. Both types of laser irradiation can lead to the risk of eye cataracts and skin burns. Therefore, corresponding protective measures should be taken according to different types of lasers, and protective glasses should be strictly worn.
Fire prevention: When laser cutting, oxygen is often used, and the sparks are splashed during the cutting process, it is easy to cause fire hazards. Therefore, there should be no flammable and explosive materials in the working area, and there should be corresponding fire prevention facilities.
