May cause irritation of the digestive tract.
May cause allergic respiratory tract irritation. Inhalation of dust may cause respiratory tract irritation.
May cause skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material.
Dust may cause mechanical irritation. Dusts may cause persistent eye irritation and conjunctivitis. Prolonged exposure to respirable crystalline quartz may cause delayed lung injury/fibrosis (silicosis).
If victim is conscious and alert, give 2-4 cupfuls of milk or water Never give anything by mouth to an unconscious person. Get medical aid immediately.
Remove from exposure to fresh air immediately. If not breathing give artificial respiration. If breathing is difficult, give oxygen Get medical aid.
