What is the primary hazard of Ammonia ($NH_3$) when carried on gas tankers?
Direct Answer
Option B: High toxicity, corrosive nature, and stress corrosion cracking in steel
Ammonia is highly toxic and corrosive, posing severe health risks upon inhalation or skin contact. Furthermore, it causes stress corrosion cracking in carbon-manganese steels, requiring specialized material selection and strict moisture control within cargo tanks as specified in the IGC Code for the carriage of toxic liquefied gases.
