Which entity determines the nominal ocular hazard distance?

The nominal ocular hazard distance (NOHD) is determined by the Laser Safety Review Board. This entity is responsible for evaluating the potential hazards associated with laser operations and establishing safety guidelines. The NOHD is the distance at which the level of laser radiation is considered safe for the eyes during exposure. Accurate assessment of the NOHD is crucial for implementing safety measures in environments where lasers are used, ensuring that personnel and equipment are kept at safe distances to prevent eye injury from laser radiation.

The Laser Safety Review Board typically includes experts in laser safety who consider various factors such as the type of laser, its power output, and potential exposure scenarios when establishing the NOHD. This ensures that all operations involving lasers are conducted with the utmost safety precautions in mind, mitigating risks associated with laser exposure for individuals working in that environment.
