How Putrefaction process is connected to Carbon Monoxide?

✓

Direct Answer

Option B: Putrefaction process depletes the oxygen in the tank due to chemical reaction

Putrefaction, the anaerobic decomposition of organic matter, primarily depletes oxygen within enclosed spaces like cargo tanks. This oxygen consumption creates an oxygen-deficient atmosphere, a significant hazard for personnel, as highlighted in ISGOTT, rather than directly generating carbon monoxide.
