Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Study period:
- 27 February 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Follows sounds scientific evaluation based on structure.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The oxygen balance is calculated from the empirical formula of the compound in percentage of oxygen required for complete conversion of carbon to carbon dioxide and hydrogen to water.
- GLP compliance:
- no
- Parameter:
- other: More sensitive to shock than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- other: no data
- Parameter:
- other: More sensitive to friction than m-dinitrobenzene
- Remarks:
- migrated information
- Remarks on result:
- other: no data
- Parameter:
- other: Explosive under influence of flame
- Remarks:
- migrated information
- Remarks on result:
- other: no data
- Parameter:
- other: Explosive (not specified)
- Remarks:
- migrated information
- Remarks on result:
- negative (not further specified)
- Interpretation of results:
- non explosive
- Remarks:
- Migrated information
- Conclusions:
- Calculation based on structure and oxygen balance was carried out and determined that the substance was not potentially explosive. In accordance with EU-REACH regulations no further study needs to be carried out.
- Executive summary:
The oxygen balance value is a greater positive than -200, suggesting that the substance may be potentially explosive, but this takes no account of the largely dissociated nature of the substance. In addition, the substance does not contain any groups which are a known structural alert for explosivity therefore, on the basis of structure, bismuth subnitrate is considered not to have the potential to be explosive. Therefore, in accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.11, an explosivity study does not need to be conducted.

Description of key information
Bismuth subnitrate is non explosive
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Calculation based on structure and oxygen balance was carried out and determined that the substance was not potentially explosive. In accordance with EU-REACH regulations no further study needs to be carried out.
Justification for classification or non-classification
The test item has been shown to have no explosive properties therefore the substance is not classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
