Endpoint summary
Administrative data
Description of key information
Lithium nitride is regarded as corrosive to the skin.
Key value for chemical safety assessment
Skin irritation / corrosion
Link to relevant study records
- Endpoint:
- skin irritation / corrosion, other
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- GLP compliance:
- not specified
- Irritation parameter:
- overall irritation score
- Remarks on result:
- probability of severe irritation
- Interpretation of results:
- Category 1 (corrosive) based on GHS criteria
- Endpoint:
- skin corrosion: in vitro / ex vivo
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study need not be conducted because the available information indicates that the criteria are met for classification as corrosive to the skin or irritating to eyes
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
Lithium nitride reacts with water and moisture (e.g. on the skin) forming alkaline solutions of ammonia and lithium hydroxide. Both substances are able to irreversibly damage eyes, skin and respiratory tract. Additionally, ammonia is officially classified as skin corrosive cat. 1B (H314) according to Annex VI of Regulation (EC) No 1272/2008. Thus, lithium nitride is classified as skin corrosive.

Lithium nitride reacts with water and moisture (e.g. on the skin) forming alkaline solutions of ammonia and lithium hydroxide. Both substances are able to irreversibly damage eyes, skin and respiratory tract. Lithium nitride is therefore classified as skin corrosive.
Endpoint conclusion

- study scientifically not necessary / other information available
- Justification for data waiving:
- the study need not be conducted because the available information indicates that the criteria are met for classification as corrosive to the skin or irritating to eyes

Additional information
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VII, section 8.1 and 8.2, studies for eye and skin irritation do not need to be conducted if the available information indicates that the criteria are met for classification as corrosive to the skin or irritating to eyes.
According to the Hommel handbook data, lithium nitride reacts with water and moisture (e.g. on the skin) forming alkaline solutions of e.g. ammonia and lithium hydroxide. Both substances are able to irreversibly damage eyes, skin and respiratory tract. Additionally, ammonia is officially classified as skin corrosive cat. 1B (H314) according to Annex VI of Regulation (EC) No 1272/2008. Thus, lithium nitride is classified as skin corrosive and severely eye damaging.
Justification for classification or non-classification
The available data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance needs to be classified as skin corrosive cat 1B and as severely eye irritating cat. 1 (H314, causes severe skin burns and eye damage) according to Regulation (EC) No. 1272/2008.
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.
