Nanomaterial Occupational Risk Management Matrix

This section provides a conceptual framework for occupational risk management designed to control and minimize exposures to engineered nanomaterials in the presence of uncertainty. Each organization should have a management structure to assess and minimize risk.

Below is the GoodNanoGuide OHS matrix in which the potential handling hazards of nanomaterials are rows labeled by the leftmost column, and the various physical forms of the nanoparticles are in four vertical columns (if you would like to approach this topic in a narrative style, please refer to the OHS Reference Manual.
