Mutagenic Effects :
No data concerning any mutagenic in vivo or in vitro effect on cells of mammals has been found in the consulted documentary sources.
First Aid :
I-Inhalation :
Move the worker to fresh air. Seek medical care if the individual presents respiratory problems.
II-Ingestion :
If large amounts are ingested, give water to drink and seek medical advice.
III-Skin Contact :
Copiously wash the affected area with water. Ask for medical advice if irritation develops.
IV-Ocular Contact :
Copiously wash with running water. Ask for medical advice if irritation develops.
Québec's Exposure Limit :
VEMP = 10 mg/m³, as total dust containing less than 1% crystalline silica.
