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

Pentachlorophenol is a very toxic biocide. 16 T of pentachlorophenol in 23 kg paper bags were lost inside containers. Containers were located with a colour video fish finder "Chromoscope", damaged with their content scattered at seabed. 90% of pentachlorophenol was recovered over 10 days, bay an airlift dredge, guided by a pile grid. The dredged mud-water mixture was treated by flocculation and an active carbon system in a barge.

Fate and weathering facts observed/reported

Three steel barrels of hydrogen bromide were knocked over board. Shortly after the collision, a white haze of hydrogen bromide enveloped Testbank. The crew secured the ship's ventilation system and took shelter below decks. The white haze was carried by the winds into a village where 75 residents were evacuated from their homes. An extensive search started for the sunk chemicals but the river water was muddy and the visibility very low. It was not until 8 days later that the each proved successful, thanks to a colour video fishfinder. Three barrels with hydrogen bromide were first very carefully salvaged and sealed in overpacks. It was finally tested in a clean water barge before being returned to the environment. Totally 1100 tons of dewatered solid waste residue was packaged in fibre drums for transportation to disposal sites.
