At present there is insufficient information to predict all of the situations and workplace scenarios that are likely to lead to exposure to nanomaterials. However, there are some workplace factors that can increase the potential for exposure. These include:
Potential exposure locations that should be considered in any guideline for working with engineered nanomaterials includes:
