What is the primary danger of Nitrogen gas used for inerting chemical tanks?
Direct Answer
Option D: Oxygen displacement causing rapid asphyxiation and unconsciousness without warning
Nitrogen, while inert, displaces oxygen. Its primary danger is rapid asphyxiation. In enclosed spaces like cargo tanks, a lack of warning signs means crew can lose consciousness quickly and without distress, a critical hazard addressed by MARPOL Annex II and ISGOTT.
