Description of key information

No man-made mineral fibre has shown acute toxic effects even after very large inhalation and instillation studies where physical damage was avoided. No treatment related lethality or acute damage to any organ system has been detected in chronic or sub chronic studies with the fibres under discussion in this dossier.

Key value for chemical safety assessment

Additional information

The material from which these fibres are made is not itself toxic. Any toxicity is due to the fibres' morphology and this is unlikely to cause acute effects.

Justification for classification or non-classification

No acute effects have been detected. Dosing at extremely high levels is not feasible as aerosol generation is problematic and the substance could physically interfere with physiological functions including breathing and ingestion
