Radiation is everywhere in our daily lives—computers, mobile phones, hair dryers, and copiers all emit radiation. While most radiation is minimal and manageable with proper precautions, the radiation from laser cutting machines requires special attention. In particular, laser radiation can cause serious eye damage if proper protection is not taken. Here’s what you need to know and how to stay safe.
Beginners often stare directly at the cutting head , watching sparks during operation. Prolonged exposure can cause eye irritation or even irreversible retinal damage. Laser beams are highly concentrated in both space and time. When focused onto the retina, the energy density increases dramatically, far exceeding what the cornea can handle. Even very low levels of laser energy can cause retinal burns.
Always wear certified laser safety goggles and never look directly at the beam or sparks.
If laser power is too strong, it can damage skin tissue. While minor burns may heal naturally, prolonged or repeated exposure can cause more severe injuries such as burns or scars. Although less dangerous than eye damage, skin safety should not be ignored.
Avoid exposing skin directly to the beam and never touch freshly cut parts immediately.
Laser cutting generates high temperatures and releases gases and fine dust particles. Cutting certain metals can produce chemical fumes that remain suspended in the air and harm the respiratory system.
Always operate with proper ventilation and dust extraction systems, and wear a mask when necessary.
Wear laser safety glasses designed to block specific wavelengths and prevent eye damage. Ensure that others in the workspace also avoid direct exposure.
Maintain a healthy diet with foods rich in Vitamin A, Vitamin C, and protein (such as carrots, bean sprouts, tomatoes, lean meat, and animal liver). Green tea is also beneficial for protecting the eyes against radiation.
Use dust removal systems and operate in a well-ventilated environment. Wearing masks can further reduce inhalation of harmful particles.
Darken the workspace walls and surroundings with darker paint to reduce reflection and secondary radiation exposure.
Avoid touching cut parts immediately after processing, as residual heat can cause burns.
By following these precautions, operators and staff can significantly reduce the risks associated with laser cutting machines, ensuring a safer, healthier, and more efficient working environment.
