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

74 containers were lost, sinking in waters 3000 m deep. Fourteen containers carried products classified as marine pollutants. One contained carried 3 laboratory irradiators with their radioactive sources. The Caesium protective cells, designed to resist a pressure of 20 atm, would have exploded during container sinking. The French Institute of Protection and Nuclear Security (OPSN) carried out assessments of the possible impact on human beings and on fauna of the area, concluding that because of the great depth, a high dilution capacity limited the exposure. The risk to human consumers was considered minimal, as trawling in the zone is carried out at a depth of less than 2000 m.
