Acute Toxicity: inhalation
Administrative data
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Section 2 of REACH Annex XI, this study does not need to be conducted as testing is not technically possible. It is not possible to produce a powdered form of the substance suitable for testing as the powdered form is flammable.
It is not possible to generate an atmosphere of test material that would be suitable for testing. The smallest size of substance that can be generated without the risk of fire would be too dense to produce a test atmosphere for testing.
Furthermore, exposure of humans via inhalation will not occur as the substance is not used in powdered form and the powdered form of the substance will not be generated during substance use.
