Safety Directions
1
Wear a dust mask or respirator to prevent inhaling fine particles, as prolonged exposure may irritate the respiratory system.
2
Use gloves and safety goggles to avoid irritation from contact with the skin and eyes.
3
Avoid sweeping or dry handling that may release dust. Use vacuum systems or damp methods for cleaning.
4
Do not eat, drink, or smoke while handling silica fume to avoid accidental ingestion.
5
Dispose of unused material and packaging in accordance with local regulations.
6
In case of eye or skin contact, rinse thoroughly with water and seek medical attention if irritation persists.
7
If inhaled, move to fresh air, and seek medical help if breathing difficulty occurs.
