Reference
Endpoint:
explosiveness
Type of information:
other: Expert statement
Adequacy of study:
key study
Study period:
2015
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Expert statement
Qualifier:
no guideline followed
Principles of method if other than guideline:
The screening procedure described in the following guidances was used:
- CLP, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3
- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria
- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3
GLP compliance:
no
Parameter:
other: Presence of chemical structures associated with explosive properties
Remarks on result:
other: no structures associated with explosive properties are present in the molecule
Parameter:
other: Oxygen balance
Value:
-130.58
Remarks on result:
other: higher than the trigger value of -200.
Parameter:
other: Exothermic decomposition energy
Remarks on result:
other: The curve displays one exothermic peak between 300 and 350 °C representing substance decomposition. As a result, the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Screening evaluation

Analysis of the above depicted molecular structure revealed, that no such chemical alert structures are present in the molecule.

Calculation of the oxygen balance according to the above mentioned formula is -130.58 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy

The curve displays one exothermic peak between 300 and 350 °C representing substance decomposition. As a result, the overall energy release is below a critical trigger level of 500 J/g and the onset of energy release is below 500 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
FAT 41001 is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
Executive summary:

No experimental test data for assessment of explosiveness according to EU Method A.14 or comparable methods for Reactive Blue 049 are available. Hence an expert judgment based on the screening procedure as described in below mentioned guidelines was conducted:

- CLP Regulation, Annex I, Part 2, paragraphs 2.1.4.2 and 2.1.4.3

- Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria

- Technical Guidance Document on the Information Requirements for REACH, Part 2 EWG 1-7, REACH Implementation Project (RIP) 3.3 Phase 2, chapter 7.1.11.3

Analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.

Description of key information

Analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
