Who determines the boundaries of the Nominal Hazard Zone?

The boundaries of the Nominal Hazard Zone (NHZ) are determined by the Laser Safety Officer (LSO). The LSO is a designated individual responsible for overseeing the safety measures related to laser operations. This role includes conducting risk assessments to establish safe operating conditions and defining the NHZ, which is the area around a laser system where hazardous exposure may occur.

The LSO evaluates various factors, such as the type of laser, its power, potential hazards, and the environment in which it operates, to accurately delineate the boundaries of the NHZ. This ensures that appropriate safety measures are implemented to protect individuals from accidental exposure to laser radiation.

Other roles mentioned, like the Laser Technician, Facility Manager, and Health and Safety Officer, may have responsibilities related to laser operations or overall safety in the facility, but the specific task of determining the NHZ is primarily within the jurisdiction of the LSO. By governing this aspect of laser safety, the LSO helps prevent accidents and enhances safety protocols in laser use.
