APPENDIX C
                  NFPA CLASSIFICATION OF SOME COMMON
                     LIQUIDS USED IN LABORATORIES

The list below contains commonly used liquids in research settings.
This list is not exhaustive. The chemical classification system of the
National Fire Protection Association (NFPA) is used to classify
laboratory fire hazards based on the types and quantities present. Use
this appendix in conjunction with a chemical inventory and Figure 3-5-
4 and Figure 3-5-1 to classify the fire hazards and construction
requirments of a particular laboratory.
