An assessment of the chemical structure of hexachlorocyclopentadiene did not show any functional groups associated with explosive behaviour (as described in “Guidance in the Application of the CLP Criteria”, Version 4.1, section 2.1.4.2). In addition, thermal testing of the substance showed no thermal event between 20°C and 600°C. Therefore, it can be concluded the hexachlorocyclopentadiene does not display any explosive properties without the need to confirm this experimentally.

Interpretation of results:
GHS criteria not met
Conclusions:
The expert assessment concluded that the substance does not display any explosive properties
Executive summary:

Hexachlorocyclopentadiene has been assessed for explosiveness. The assessment is based on an examination of the chemical structure of the substance for functional groups associated with explosive behaviour, in addition to analysis of thermal testing results. It was found that the chemical structure of the substance did not show any functional groups associated with explosive behaviour (as described in "Guidance on the Application of the CLP Criteria", Version 4.1, section 2.1.4.2). Additionally, thermal testing of the substance showed no thermal event between 20 °C and 600 °C. Therefore, it can be concluded that Hexachlorocyclopentadiene does not exhibit any explosive properties.

Description of key information

An expert assessment was performed to determine the explosiveness of the substance. It was concluded that Hexachlorocyclopentadiene does not display any explosive properties due to the lack of any functional groups associated with explosive behaviour, and the lack of any thermal event occurring between 20 °C and 600 °C.

Key value for chemical safety assessment

Explosiveness:
non explosive

Justification for classification or non-classification

Hexachlorocyclopentadiene has been assessed for explosiveness. The assessment is based on an examination of the chemical structure of the substance for functional groups associated with explosive behaviour, in addition to analysis of thermal testing results. It was found that the chemical structure of the substance did not show any functional groups associated with explosive behaviour (as described in "Guidance on the Application of the CLP Criteria", Version 4.1, section 2.1.4.2). Additionally, thermal testing of the substance showed no thermal event between 20 °C and 600 °C. Therefore, it can be concluded that Hexachlorocyclopentadiene does not exhibit any explosive properties.
