What is the primary purpose of evaluating the Nominal Hazard Zone?

The primary purpose of evaluating the Nominal Hazard Zone (NHZ) is to define the space where control measures are required. The NHZ represents the area around a laser where a person could be exposed to hazardous levels of laser radiation, which necessitates appropriate safety measures to protect individuals. This includes setting up barriers, implementing access controls, and ensuring that safety equipment is in place to prevent unintended exposure.

Understanding the NHZ helps Laser Safety Officers and other personnel make informed decisions about how to manage and mitigate hazards associated with laser use. By clearly identifying this zone, organizations can implement necessary safety protocols effectively.

While other options relate to laser safety management, they do not capture the primary intent of NHZ evaluation as accurately. For instance, defining a laser's intensity, identifying areas for administrative controls, or determining laser classification play roles in overall safety measures, but the NHZ specifically focuses on pinpointing the physical space that requires immediate attention and control mechanisms to safeguard users and bystanders.
