Description of key information

Green liquor is always manufactured as an aqueous solution of alkaline inorganic salts. None of these salts, in wet or dry form, are classifiable as explosive. In dry forms, these salts may pose a danger of explosion if heated.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

The molecular/ionic structure of GL and its constituents do not indicate the presence of highly reactive or unstable groups. The known structure does not indicate that GL presents a danger of explosion when submitted to the effect of a flame or shock under the conditions of the test as described in Test Guideline A.14 of EC Regulation No 440/2008.

Green liquor is always manufactured as an aqueous solution of alkaline inorganic salts. None of these salts, in wet or dry form, are classifiable as explosive according to C&L rules or presents any other danger of explosion in normal handling conditions. Dry salts e.g. Na2S may be hazardous and explode if it is heated to very high temperatures.

The available information is adequate to decide that green liquor should not be classified for explosivity and there is no need for further actions regarding this assessment end point.
