Description of key information

Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Additional information:

Classical skin sensitisation studies are not technically feasible as the substance is a gas at room temperature. However there is no reported evidence of skin sensitisation in humans, despite wide industrial use for many years.


Migrated from Short description of key information:
There are no animal studies addressing sensitisation. However there is no reported evidence of skin sensitisation in animals or humans.

Respiratory sensitisation

Endpoint conclusion
Additional information:

No data have been found concerning respiratory sensitisation and there is no evidence of respiratory tract sensitisation in either animals or humans.


Migrated from Short description of key information:
There are no specific data on respiratory sensitisation.

Justification for classification or non-classification

Although there are no specific data on respiratory sensitisation, there is no evidence that classification is warranted for this end-point under Dir 67/548/or GHS/CLP.
