The offshore supply vessel Island Captain spilled hydroholic acid in North Sea and caused water pollution. The accident happened during well maintenance works off Esbjerg. The quantity of spilled acid is unknown, but the crew of the ship reported about the accident and took all the corrective action to restrict the spill. At the scene of the accident was dispatched rescue boat with water cleansing equipment. The vessel returned to Esbjerg for check and cleansing, which were carried out by special team and vehicles. The crew left the ship until cleansing completed, as the acid is very dangerous for human health. There are no injured people, but all the crew members will be medical examined.
Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride (HCl) in water. It is a highly corrosive, strong mineral acid. Hydrogen chloride (HCl) is a monoprotic acid, which means it can dissociate only once to give up one H+ ion (a single proton). Concentrated hydrochloric acid forms acidic mists. Both the mist and the solution have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines irreversibly. Upon mixing hydrochloric acid with common oxidizing chemicals, such as sodium hypochlorite or potassium permanganate, is produced the toxic gas chlorine.
