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

Acrylonitrile is highly flammable, toxic and polymerizes violently. It has a flashpoint of 0ºC, which means that its vapours become flammable at any temperature above the freezing point of the water. Vapours also burn so rapidly that they appear to explode, specially in a confined area. It is toxic in both vapour and liquid form and can be lethal in high concentrations. The personnel from the chemical company monitored the atmosphere and the water. No traces of toxic fumes were recorded.
