CBMNG

“CBMNG” Means Coal Bed Methane Natural Gas.
“Combustible liquid” means any liquid having a flashpoint at or above 100°F. (37.8°C.). (See definition of “Flashpoint”) Combustible liquids shall be divided into two classes as follows:
(A) “Class II liquids” shall include those with flashpoints at or above 100°F. (37.8°C.) and below 140°F. (60°C.) except any mixture having components with flash points of 200°F. (93.3°C.) or higher, the volume of which make up ninety-nine (99) percent or more of the total volume of the mixture. Example: Stoddard Solvent; No.2 Fuel Oil.
(B) “Class III liquids” shall include those with flashpoints at or above 140°F. (60°C.). Class III liquids are subdivided into two sub-classes:

  1. “Class IIIA liquids” shall include those with flashpoints at or above 140°F. (60°C.) and below 200°F. (93.3°C.), except any mixture having components with flashpoints of 200°F. (93.3°C.), or higher, the total volume of which make up ninety-nine (99) percent or more of the total volume of the mixture. Example: Fuel Oil No. 6.
  2. “Class IIIB liquids” shall include those with flashpoints at or above 200°F. (93.3°C.). Example: Ethylene Glycol.

(C) When a combustible liquid is heated for use to within 30°F. (16.7°C.) of its flashpoint, it shall be handled in accordance with the requirements for the next lower class of liquids.
