What are the hazards of industrial lasers and how to protect them?

The laser is a high-brightness, high-power, high-energy beam. Intense laser exposure can cause burns to the human skin. If it is directly injected into the eye or reflected from a bright (mirror) surface, it can also cause damage. Will cause permanent damage to the eyes until blindness. Therefore, it should be avoided to place any part of the body in the light path of the laser. In particular, special attention should be paid to the protection of the eyes and skin to avoid injury.

Different types of lasers cause different damage to the human body. In laser processing, CO2 and YAG lasers are usually the most used. The YAG laser may damage the retina of the eye, and the wavelength of the YAG laser is extremely high in the transmittance of the eye, and the damage is also greater. The hazard of CO2 laser is mainly the burn on the cornea of the eye. Both kinds of laser irradiation may cause cataract in the eyes and burns on the skin. Therefore, when adjusting the laser, the corresponding protective measures should be adopted according to the type of laser.

Also pay attention to fire protection. When laser processing, auxiliary gas is often used, and there is spark splash during processing, which is easy to cause fire hazard. Therefore, it is forbidden to place flammable and explosive materials in the work area, and at the same time, it must have corresponding preventive facilities.
