Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information
This substance is void of any chemical structures commonly associated with explosive properties, such as metal peroxides, peroxo-acid-anions, azides, and halogen oxides. As2O3 is thermodynamically stable (no oxidation in air to form As2O5). Further, it is noted that despite long-term industrial use of the substance, it is not classified for explosive properties according to UN transport regulations (in accordance with section 1 of REACH Annex XI). Thus, any explosive properties are not plausible and experimental confirmation is scientifically unjustified.
Key value for chemical safety assessment

- non explosive
Additional information
Justification for classification or non-classification
This substance is void of any chemical structures commonly associated with explosive properties, such as metal peroxides, peroxo-acid-anions, azides, and halogen oxides. As2O3 is thermodynamically stable (no oxidation in air to form As2O5). Further, it is noted that despite long-term industrial use of the substance, it is not classified for explosive properties according to UN transport regulations (in accordance with section 1 of REACH Annex XI). Thus, any explosive properties are not plausible and experimental confirmation is scientifically unjustified.
In conclusions, As2O3 should not be hazard classified for explosive properties.
