G40 Use Liquefied Petroleum Gas or Compressed Natural Gas for Tar Kettles The G40 focuses specifically on LPG and CNG fuel systems for tar kettles, whereas broader gas safety certifications cover general appliance installation across multiple industries. This narrow specialization means you’ll study pressurized fuel handling, regulator maintenance, and kettle-specific safety protocols—details that generic gas certifications gloss over. Contractors working in roofing and road construction rely on this distinction to operate equipment legally and safely.
