Parameter:

other: Presence of chemical structures associated with explosive properties

Value:

0

Remarks on result:

other:

Remarks:

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.

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 -57.23 and therefore higher than the trigger value of -200.

Determination of the exothermic decomposition energy:

The curve displays one exothermic peak between 340 and 350 °C with an energy release of 21.18 J/g. This peak is considered to represent substance decomposition energy. As a result, 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:

The substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008.

Executive summary:

The explosiveness of Reactive Orange 35 was assessed in an expert statement using the screening procedure as described in:

- 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

Analysis of the chemical structure revealed no alerts for explosive properties. The calculated chemical oxygen balance was 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

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

Reactive Orange 035 is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008, hence no classification is warranted according to the criteria set by the Regulation (EC) No. 1272/2008.
