Why must sea water NEVER be ingested by survivors in a life raft?
Direct Answer
Option A: High salt concentration causes kidney dehydration, rapid delirium, and fatal kidney failure
In accordance with SOLAS Chapter III survival guidance, seawater contains high solute concentrations that exceed human renal excretion limits. Processing this excess salt forces the kidneys to draw water from body tissues, causing accelerated dehydration, acute electrolyte imbalance, rapid delirium, and terminal renal failure.
