CHEMCO Exit Exam • Set 8 Question 9 of 30

In which of the following conditions, the IG blower fans should shut down automatically?

✓

Direct Answer

Option D: High scrubber water level

High scrubber water level indicates a potential blockage or failure in the scrubber's drainage or circulation system. This condition can lead to the scrubber becoming ineffective, allowing excessive oxygen into the inert gas supply, thus posing a significant fire hazard. Automatic shutdown prevents this risk.

All Options

Oxygen content above 8%

Low water level in deck seal

Low water level in the scrubber tower

High scrubber water level (Correct Answer)

Detailed Explanation & Context

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