The fabrication of micro and nano devices requires the use of several types of chemicals, both inert and hazardous.  OSHA requires specific information about a chemical to be on its label. This learning module provides information needed to interpret chemical labels and symbols used.  One such symbol is the NFPA diamond developed by the National Fire Protection Association.  Upon completion of this learning module one should be able to describe the information found on a NFPA diamond and a chemical label.
