Laser is a high-brightness, high-power, high-energy beam, intense laser radiation can cause burns on human skin, can also cause damage if directly into the eye, or from a glossy (mirror-like) surface reflection , will cause permanent eye damage until blindness. Therefore, any part of the body should be avoided by the laser into the optical path, in particular, should pay special attention to eye and skin protection, so as to avoid injury. Different types of laser, to harm the human body is different. In the laser processing, usually CO2, maximum use of fiber lasers. Fiber laser may damage the retina of the eye, because the high wavelength fiber laser eye transmittance, harm is greater. CO2 laser is mainly harm the eye cornea burns. Two kinds of laser irradiation are likely to cause eye cataracts, burns on the skin. Therefore, when adjusting the laser, according to the different types of laser, using appropriate protective measures. Also note that fire protection. Laser processing, often used auxiliary gas, coupled with the presence of sparks flying during processing, easy to cause a fire hazard, so the work area prohibit placing inflammable and explosive materials, but to have the appropriate preventive facilities.
