Nanomaterials are extremely small and have dimensions roughly between 1-100 nanometres (nm). A nanometre is 1 billionth of a metre.

Nanomaterials are in the workplace and in the home:

Are nanomaterials hazardous? The best approach is the precautionary principle - the need to take prudent action in the face of potentially serious risk, without waiting for the completion of further scientific research.
