Supplier Details: Name, address, and emergency contact number provided by manufacturer
GHS Classification: Not classified as hazardous under GHS; minimal toxicity hazard
Physical Hazards: Non-flammable, non-explosive
Health Hazards: Inhalation of dust may irritate respiratory tract, eye and skin irritation possible with prolonged contact
Environmental Hazards: Not known to cause significant ecological harm
Label Elements: No pictogram required; precautionary advice about dust precaution
Chemical Composition: Pure silicon dioxide (SiO2) in bead form
Purity: Typically over 99% SiO2
Impurities: Minor trace minerals and water molecules absorbed during manufacturing
Inhalation: Move to fresh air, drink water if throat irritation develops; seek medical attention if persistent discomfort occurs
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, consult a physician if irritation persists
Skin Contact: Wash with soap and water if irritation develops; remove contaminated clothing
Ingestion: Rinse mouth, drink water to dilute, seek medical attention if large amounts consumed accidentally
Suitable Extinguishing Media: Use extinguishing media appropriate for surrounding materials; silica gel does not ignite
Special Hazards: Product does not burn or emit hazardous fumes in a fire
Protective Equipment: Standard fire-fighting gear; avoid breathing dust created by large spills affected by fire water run-off
Personal Precautions: Avoid creating dust clouds, use personal protection for eyes and nose
Methods for Clean-up: Sweep, scoop, or vacuum the product; place into a suitable container for reuse or disposal
Environmental Precautions: Prevent release into drains as beads may swell and cause blockages, but no chemical hazard to groundwater
Handling: Use with adequate ventilation, avoid dust inhalation or direct prolonged contact
Storage: Store in cool, dry, well-ventilated area in sealed containers away from moisture, acids, and bases
Special Requirements: Keep away from children and pets due to possible choking hazard
Permissible Exposure Limits: OSHA PEL for amorphous silica: 20 mppcf (million particles per cubic foot of air) as an 8-hour TWA
Engineering Controls: General or local exhaust ventilation recommended for bulk handling
Personal Protective Equipment: Safety glasses, gloves, and dust mask in case of large-scale or industrial use; standard hygiene practices in everyday use
Appearance: Hard, translucent to white beads
Odor: Odorless
pH: 4-8 (in slurry)
Melting Point: 1610°C
Boiling Point: Not applicable
Solubility: Insoluble in water and organic solvents
Vapor Pressure: Not applicable
Density: 2.2 g/cm³
Molecular Formula: SiO2
Other Properties: Highly adsorptive, moisture capacity up to 35-40% of own weight
Chemical Stability: Stable under normal temperatures and pressures
Conditions to Avoid: Exposure to strong acids or bases may lead to product degradation and release of heat
Incompatible Materials: Hydrofluoric acid (reacts, forming toxic gas); strong alkalis
Hazardous Decomposition Products: None under recommended storage and handling conditions
Acute Toxicity: Low; oral LD50 values for rats above 5,000 mg/kg
Inhalation Risks: Prolonged exposure to dust could irritate respiratory system; chronic exposure to crystalline silica (not typical in desiccant form) linked to silicosis
Skin/Eye Contact: Mild irritation can result from repeated or prolonged contact; generally non-toxic by skin absorption
Chronic Effects: No evidence of carcinogenic hazard for amorphous silica; crystalline silica (not present) classified by IARC as group 1 carcinogen
Environmental Fate: Inert, insoluble in water, not bioaccumulative
Aquatic Toxicity: Practically none; does not leach into aquatic systems or cause harm to aquatic life
Persistence and Degradability: Non-degradable, remains as inert solid in environment
Disposal Method: Dispose of in accordance with local, state, and federal regulations; landfill disposal typical for non-contaminated beads
Special Considerations: Do not flush in large quantities to drains or sewers to prevent clogging; recycled or regenerated for reuse where possible
UN Number: Not regulated
Proper Shipping Name: None assigned
Hazard Class: Not hazardous for transport
Packing Group: None
Environmental Hazards: None anticipated
Special Precautions: Transport in sealed containers to avoid spillage and dust formation
Occupational Safety: Covered by OSHA for nuisance dusts; amorphous silica not classified as hazardous under US and EU regulations
TSCA Status: Listed
EINECS Number: 231-545-4
RoHS/WEEE: Compliant
California Proposition 65: Not subject to warning requirements except for products with crystalline silica contamination
SARA Title III: Not a reportable substance
Other Local Regulations: Observe all national, regional, and local provisions and standards regarding occupational exposure, environmental safety, and product labeling
