A complete understanding of the scope and limitations of NFPA 30 is desirable when using it as a guide and essential where it is referenced in laws or ordinances. The words "flammable" and "combustible" have essentially the meanings of common usage, subject to the limitations given in this section and the definitions given in Section 1-7 of NFPA 30. Additional commentary on this topic is offered in Section 1-7.
The words "including waste liquids" were added in 1990 to emphasize that NFPA 30 applies to these liquids as well. It must be recognized that the fire hazard properties of a given liquid will generally be the same, regardless of whether that liquid is virgin material or a waste material that is destined for disposal or recycling.
1.1.2 This code shall not apply to the following:
(a) Any liquid that has a melting point equal to or greater than 100℉ (37.8℃) or that does not meet the critieria for fluidity given in the definition for "Liquid" in Section 1-6 of this code;
