G-44 STORAGE AND HOLDING OF LPG/CNG QUESTIONS AND
ANSWERS
Asphalt Melter: - CORRECT ANSWER✅✅An approved device designed to heat asphalt, typically for
waterproofing operations, that, utilizing a flammable gas or a combustible liquid, generates an enclosed
flame that indirectly heats a vessel containing the asphalt.
CNG: - CORRECT ANSWER✅✅Compressed natural gas.
Compressed Gas: - CORRECT ANSWER✅✅A material, or mixture of materials, that is a gas at 68F or less
at 14.7 psia of pressure; and has a boiling point of 68F or less 14.7 psia that is either liquefied, non
liquefies or in solution at that temperature and pressure, except that gases which have no other health-
or physical-hazard properties are not considered to be compressed until the pressure in the packaging
exceeds 41 psia at 68F. Compressed gases shall be classified as follows:
Nonliquefied compressed gases: - CORRECT ANSWER✅✅Gases, other than those in solution, that are in
a packing under the charged pressure and are entirely gaseous at temperature of 68F
Liquefied compressed gases: - CORRECT ANSWER✅✅Gases that, in a packing under the charged
pressure, are partially liquid at a temperature of 68F
Compassed Gases in solution: - CORRECT ANSWER✅✅Nonliquefied gases that are dissolved in a solvent
Compassed gas mixtures: - CORRECT ANSWER✅✅A mixture of two or more compresses gases
contained in a single packaging, the hazard properties of which are represented by the properties of the
mixture as a whole.
Electric Barbecue: - CORRECT ANSWER✅✅Any device designed for heating or cooking food on an open
grate cooking surface above exposed heating elements. An electric grill that has its heating elements
embedded within a solid cooking surface is not an electric barbecue.
Flammable Gas: - CORRECT ANSWER✅✅A material which has a boiling point and becomes a gas at 68F
(20C) or less at 14.7 pounds per square inch absolute (psia) (101 KPa) of pressure which:
