Potential Hazards. Identify potential chemical and safety hazards using the Material Safety Data Sheet (MSDS) for the nanomaterial or parent compound. The toxicity of the nanomaterials may be greater than the parent compound. Special consideration should be given to the high reactivity of some nanopowders with regard to potential fire and explosion, particularly if scaling up the process. Consider the hazards of any precursor materials in evaluating the process. For more information, refer to the section on “Planning your research”.
