Laser Safety

“Most lasers are capable of causing eye injury to anyone who looks directly into the beam or specular reflection. Even diffuse reflections of a high-power laser beam can produce permanent eye damage. High-power laser beams can burn exposed skin, ignite flammable materials, and vaporize materials, possibly releasing hazardous fumes, vapors, or gases. The equipment and optical apparatus required to produce the lasing action and control and direct the laser beam may introduce additional hazards. These hazards may include high voltage, high pressure, cryogenics, noise, radiation, and toxic fluids.”
