GHS Classification: Not classified as hazardous under GHS for most uses Physical Hazards: Dust may cause mechanical irritation to eyes, nose, and throat Health Hazards: Prolonged or repeated inhalation may cause mild respiratory discomfort Environmental Hazards: Not known to cause significant environmental harm Pictogram: None required Signal Word: None required Precautionary Statements: Avoid breathing dust, wash thoroughly after handling, use in well-ventilated areas if dust forms
Chemical Name: Silica, Amorphous Concentration: Typically >98% Impurities: Trace water (<2%), minor natural inorganic compounds Stabilizers/Additives: None for White Non-Indicating type Other Information: Does not contain heavy metals or added cobalt chloride
Inhalation: Move exposed person to fresh air, rinse mouth with water, seek medical attention if symptoms persist Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easily done Ingestion: Rinse mouth with water, drink plenty of water, seek medical advice if large amount swallowed Symptoms: Dust may cause temporary irritation to mucous membranes, no chronic effects known for short-term exposure
Suitable Extinguishing Media: Product itself does not burn; use media suitable for surrounding fire, including water fog, foam, dry chemical, CO2 Hazardous Decomposition Products: None, does not decompose in fire Protective Equipment: Standard firefighter turnout gear, avoid inhalation of dust drifting in air from damaged packaging Special Procedures: Cool containers with water spray, avoid stirring up dust during firefighting
Personal Precautions: Use personal protective equipment to prevent dust contact with skin, eyes, and respiratory system Environmental Precautions: Prevent material from entering drains in large quantities; sweep or vacuum up solid particles, avoid creating dust clouds Cleanup Method: Collect spilled material in suitable containers for reuse or disposal, ventilate area, wash spilled surface with water after cleanup Advice for Emergency Responders: Wear dust mask or respirator if dust generation is high, use safety goggles and gloves
Handling: Avoid contact with eyes and skin, prevent dust generation, handle in a dry area away from incompatible materials, do not eat or drink during use Storage: Store in a tightly sealed container in a cool, dry place away from moisture, incompatible with hydrofluoric acid and strong alkalis, keep out of reach of children and pets Incompatible Materials: Hydrofluoric acid, strong bases Packaging Materials: Preferably packaged in moisture-proof, airtight containers or bags
Occupational Exposure Limits: OSHA PEL for amorphous silica—20 mppcf (80 mg/m3 ÷ % SiO2) Engineering Controls: Ensure adequate ventilation, use local exhaust if dust develops, implement dust control measures in bulk handling Personal Protective Equipment: Dust mask or NIOSH-approved respirator, chemical-resistant gloves, goggles or face shield to prevent eye contact, work clothing that covers skin Hygiene Measures: Wash hands after handling, remove contaminated clothing, avoid touching eyes or face
Appearance: White or translucent beads/granules Odor: Odorless pH: Neutral, typically 6–8 when dispersed in water Boiling Point: Not applicable (solid, does not boil) Melting Point: 1,710°C (3,110°F) Flash Point: Not flammable Explosive Properties: None Vapor Pressure: Negligible Solubility: Insoluble in water and most solvents Bulk Density: Varies, typically 450–750 kg/m3 Particle Size: Beads or granules commonly 1–5 mm diameter Specific Gravity: 2.1–2.3
Chemical Stability: Stable under recommended handling and storage conditions Conditions to Avoid: Exposure to strong acids or alkalis, contact with hydrofluoric acid, excessive heat over 1,600°C Materials to Avoid: Hydrofluoric acid dissolves silica, avoid strong alkalis Hazardous Reactions: No dangerous reactions under normal conditions Hazardous Decomposition Products: None known under normal conditions
Acute Toxicity: Oral LD50 (rat) >5,000 mg/kg, no acute toxicity under normal exposure Inhalation Effects: Short-term exposure to dust may cause mild irritation, no confirmed chronic effects expected from amorphous silica Skin Irritation: Prolonged contact may cause dryness or mild irritation Eye Effects: Mechanical irritation can occur due to dust Carcinogenicity: Amorphous silica is not classified as a human carcinogen by IARC or NTP Repeated Dose Toxicity: No significant adverse effects observed in studies of amorphous silica Sensitization: Not expected to cause allergic reactions
Eco-Toxicity: No acute aquatic toxicity expected, not hazardous to aquatic environment in solid form Persistence and Degradability: Chemically inert, does not break down in the environment Bioaccumulation Potential: Not bioaccumulative Mobility in Soil: Remains in granular form, limited mobility except by water transport as particle Other Effects: No known significant toxicity to plants, animals, or microorganisms
Waste Treatment Methods: Dispose according to local, regional, and national regulations; can be sent to landfill as non-hazardous waste Reuse: Product can be regenerated by heating to release absorbed moisture, where permitted by application Contaminated Packaging: Recycle or dispose of packaging following official guidance Avoid Release: Do not dispose in watercourses, avoid release of large amounts into natural environment
UN Number: Not regulated for transport Proper Shipping Name: None assigned, classified as non-dangerous goods Transport Hazard Class: Not classified Packing Group: Not applicable Marine Pollutant: No Transport Precautions: Protect packaging from moisture and rough handling to avoid breakage of containers and dust release
US TSCA: Listed (Silicon Dioxide) EINECS/ELINCS Number: 231-545-4 OSHA Hazard Communication: Not hazardous per OSHA criteria REACH Status: Registered Chemical Safety Assessment: Not required for this product Other National and International Regulations: Product complies with applicable environmental, health, and safety regulations; specific handling or use restrictions may apply depending on legislation in the country of use
