Skin Contact: Wash exposed skin with soap and water; use lotion if dryness develops
Ingestion: Rinse mouth, drink water; obtain medical help for discomfort
Notes for Physicians: Treat symptoms; no known systemic toxicity
Suitable Extinguishing Media: Silica gel does not burn; use dry chemical, foam, water spray, carbon dioxide for surrounding materials
Specific Hazards: Product remains stable in fire; dust may contribute to slipping hazard
Protective Equipment: Wear self-contained breathing apparatus and protective clothing for chemical fires
Special Precautions: Manage runoff water as it may carry traces of adsorbed hazardous material
Personal Precautions: Avoid dust formation; ventilate area; wear respiratory and skin protection
Environmental Precautions: Prevent product entering drains or water systems in large amounts
Methods for Cleanup: Sweep up; collect in labeled, sealable containers; use vacuum or wet methods if needed; clean affected area with water to remove dust residue
Disposal: Dispose according to local, state, federal regulations
Handling: Avoid contact with eyes, ingestion, inhalation of fine dust; minimize dust generation; ensure efficient ventilation
Storage: Store in cool, dry, well-ventilated area; keep containers closed and upright; segregate from strong bases and hydrofluoric acid; protect from moisture absorption
Hygiene: Wash hands, face after handling; do not eat, drink, or smoke in storage or handling areas
Occupational Exposure Limits: OSHA PEL (TWA) Total Dust 15 mg/m³, Respirable Fraction 5 mg/m³
Engineering Controls: Use local exhaust ventilation to reduce airborne concentration
Personal Protection: Respirator for dust, protective gloves, safety goggles, coveralls or long-sleeved clothing
