Description of key information

In accordance with column 2, section 9.4 of REACH Annex IX, a test on the sediment toxicity does not need to be conducted as the chemical safety assessment according to Annex I indicates that this is not necessary.  When in contact with water/moisture calcium carbide instantly decomposes hydrolytically, yielding calcium hydroxide and and acetylene. Therefore, the assessment has to based on relevant decomposition products.
