At the beginning of the 21st century nanotechnology, more specifically artificial nanomaterials (ENM) would form an important market in the world. In this way, the industry would transform the raw material to a tiny scale and it would be the workers who would be exposed to the potential risks that the handling of materials at this scale could generate. That is why it is necessary to use all the necessary tools to provide safe working environments, and thus the evaluation of risks becomes relevant by identifying hazards and evaluating risks to achieve an efficient treatment of these.
