The blowers of an inert gas generation system aboard a tanker, will be automatically secured if __________.

Correct Answer: Option D — all of the above

46 CFR 32.53 requires automatic shutdown of inert gas blowers upon loss of scrubber cooling water, loss of water seal integrity, or high discharge temperature. These safety interlocks prevent hot, non-scrubbed, or oxygen-rich gases from entering cargo tanks, which could lead to fire, explosion, or structural damage to tank coatings.
