Fate and weathering facts observed/reported
The cargo was full of HNS (including diphenyl methane, di-isocyanate, o-cresol, aniline) but only sodium spilled. Sodium is a are very reactive metals which floats and reacts violently with water, forming flammable hydrogen gas mixtures with air. The heat of the reaction often causes the hydrogen to ignite and explode. The ship went on fire when the containers filled with sodium on the deck cargo came into contact with seawater. On board there were 126 tons of sodium in 1430 drums.
