Hazard Identification

Definition

Hazard identification is the process of recognizing and evaluating potential sources of harm or adverse effects associated with materials, processes, or activities. This step is crucial in understanding the risks involved, particularly in the context of nanoparticles, as they can pose unique health and safety challenges due to their size, reactivity, and ability to penetrate biological barriers.
