What are the possible injuries that could happen if a person stood within the NOHD when a laser device was fired?

Standing within the No Hazard Distance (NOHD) when a laser device is fired poses a significant risk of eye injuries. Laser devices emit concentrated beams of light that can cause immediate damage to the retina and other sensitive structures in the eye. Depending on the power, wavelength, and exposure duration of the laser, the potential for vision loss, temporary blindness, or long-term visual impairment increases substantially.

The importance of the NOHD is rooted in safety protocols that are designed to protect individuals from these serious eye injuries. It is equally vital that those operating laser devices understand this risk and enforce strict guidelines to ensure that no one is within this hazardous zone during laser operations. While other potential effects, such as psychological trauma or physical injuries like burns and scrapes, may occur in different contexts, they are not the primary concerns associated with improper exposure to laser devices.
