Endpoint summary
Administrative data
Description of key information
Key value for chemical safety assessment
Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation, other
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is classified as skin corrosion (Category 1, 1A, 1B or 1C)
- other:
Reference
Endpoint conclusion
- Endpoint conclusion:
- no study available
- Additional information:
A waiver is proposed for this endpoint as HF is corrosive. There are no animal data which suggest that HF or fluoride are skin sensitisers; the local effects of HF exposure will be dominated by irritation/corrosion. Similarly there is no evidence of skin sensitisation from occupational exposure reports of delayed dermal effects in some accidental exposures cases are due to irritancy rather than sensitisation.
Migrated from Short description of key information:
A waiver is proposed for this endpoint as HF is corrosive.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
- Additional information:
There is currently no recognised test guideline for respiratory sensitisation. The local effects of HF exposure will be dominated by irritation/corrosion. Similarly there is no evidence of respiratory sensitisation (asthma) from occupational exposure.
Migrated from Short description of key information:
No data are available.
Justification for classification or non-classification
No classification is proposed in the absence of any indication that HF can cause sensitisation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
