- Endpoint:
- explosive properties of explosives
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1
- GLP compliance:
- not specified
- Parameter:
- other: Handbook data
- Remarks on result:
- other: Based on UNRTDG N° 1449, class:5.1(6.1), PG II, the substance BaO2 is not classified as explosive, though containing oxygen atoms adjacent to each other as chemical groups associated with explosive properties present.
- Parameter:
- other: Handbook data
- Remarks on result:
- other: The substance decomposes slowly with air. The substance is a strong oxidant which reacts violently with combustible and reducing materials. The contat with combustible substances or reducing agents may provoke a risk of fire and explosion.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance decomposes slowly with air. The substance is a strong oxidant which reacts violently with combustible and reducing materials. The contact with acids induces decomposition of the substance BaO2 producing oxygen and hydrogen peroxide which may provoke a risk of fire and explosion.
Based on UNRTDG N° 1449, class:5.1(6.1), Packaging Group II, the substance BaO2 is not classified as explosive, though containing oxygen atoms adjacent to each other as chemical groups associated with explosive properties present. - Executive summary:
The substance is not classified explosive as it is classified according to UNRTDG N° 1449, class:5.1(6.1), Packaging Group II (oxidizer).

- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Qualifier:
- according to guideline
- Guideline:
- other: no guideline available (Handbook data)
- GLP compliance:
- not specified
- Parameter:
- other: handbook data
- Remarks on result:
- other: Barium peroxide may ignite or explode in contact with reducible substances.
- Remarks:
- It reacts with dilute acids to form hydrogen peroxide.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Barium peroxide may ignite or explode in contact with reducible substances. BaO2 reacts with dilute acids to form hydrogen peroxide, unstable substance.
According to CLP Guidance (Annex I:2.1.1.1, a substance or mixture which is not itself an explosive but which can form an explosive atmosphere of gas, vapour or dust is not included in this class (i.e. explosive).

Description of key information
The test item is not classified explosive according to GHS criteria.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Justification for classification or non-classification
The substance decomposes slowly with air. The substance is a strong oxidant which reacts violently with combustible and reducing materials. The contact with acids induces decomposition of the substance BaO2 producing oxygen and hydrogen peroxide which may provoke a risk of fire and explosion.
Based on UNRTDG N° 1449, class:5.1, PG II, the substance BaO2 is not classified as explosive, though containing oxygen atoms adjacent to each other as chemical groups associated with explosive properties present.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
