Hazardous and Noxious Substances Spill Incidents

Advanced Search

On this database it is collected information on the fate and weathering of hazardous and noxious substances (HNS) accidentally spilt at the sea around the world. It gathers and systematizes existing information to assist stakeholders involved in spill preparedness and response, and builds return of experience datasheets for the chemicals involved. It will facilitate the incorporation of lessons from past incidents on the decision process to improve preparedness.

Fate and weathering facts observed/reported

Part of the content was spilled onto plastic materials on deck and the rain began to fall. The sodium peroxide, is a powerful oxidizer, which reacted vigorously with the wet plastic sheets, caused a fire that spread rapidly to other spills of peroxide on deck and thereafter to the cargo. Sodium peroxide also reacts with organic material. It decomposed by heat and may cause fire and explosion in contact to other combustibles. Sodium cyanide and potassium cyanide, which were also on board, are very toxic solids. In contact with water, moisture, oxidants or acids, they emit hydrogen cyanide, an extremely poison compound.
