EMERGENCY OVERVIEW
May cause cancer by inhalation.
Potential Health Effects
Eye:
Dust may cause mechanical irritation.
Skin:
Dust may cause mechanical irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Prolonged exposure to respirable crystalline quartz may cause delayed lung injury/fibrosis (silicosis). Cobalt compounds may cause cancer based upon animal studies.
