GASCO Exit Exam • Set 7 Question 12 of 30

What is the IGC code definition for a liquefied gas?

✓

Direct Answer

Option A: Product having a saturated vapor pressuree of 2.8 bar absolute at 37.8°C/100°F

The correct answer is Product having a saturated vapor pressuree of 2.8 bar absolute at 37.8°C/100°F. This complies with established gas tanker operational standards, thermodynamics, and the IGC Code safety requirements.

All Options

Product having a saturated vapor pressuree of 2.8 bar absolute at 37.8°C/100°F (Correct Answer)

Product having a saturated vapor pressuree of 1.76 bar absolute at 37.8°C/ 100 ° F

Product having a saturated vapor pressuree of 1.76 bar absolute at 38.7°C/1029 F

Product having a saturated vapor pressuree of 2.8 bar absolute at 38.7°C/102° F

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • Advanced Training for Liquefied Gas Tanker Cargo Operations (GASCO).
