Environmental Hazards: Not classified as dangerous for the environment
Signal Word: None
Hazard Statements: May cause mechanical irritation to eyes, skin, or respiratory system
Precautionary Statements: Avoid breathing dust; wash hands after handling; wear protective equipment where dust creation is likely
Chemical Identity: Silica Gel
CAS Number: 112926-00-8
Concentration: >99% amorphous silica
Impurities/Additives: Color-indicator types may contain organic dyes (less than 1%); possible residual water content up to 10% by weight distributed in the pores
Inhalation: Move affected person to fresh air, rest and keep warm; seek medical attention if breathing is difficult or symptoms persist
Skin Contact: Remove contaminated clothing, wash gently and thoroughly with soap and water
Eye Contact: Rinse cautiously with water for at least 10-15 minutes, remove contact lenses if present, seek medical attention if irritation remains
Ingestion: Rinse mouth and drink small amount of water; do not induce vomiting, seek prompt medical advice, especially if large amounts swallowed
Suitable Extinguishing Media: Use media appropriate to surrounding materials; silica gel doesn’t support combustion
Special Hazards: Product is not combustible; dust in contact with water may create slippery surfaces at site
Protective Equipment: Use standard personal protective gear for chemical fires (self-contained breathing apparatus, protective clothing)
Firefighting Instructions: Prevent water run-off from entering sewers or water bodies; silica has no known hazardous decomposition products under normal fire conditions
Personal Precautions: Wear dust mask, safety goggles, and gloves to avoid skin or eye contact; ventilate area of spill
Environmental Precautions: Prevent product entry into drains or natural waterways in bulk form
Cleanup Methods: Sweep or vacuum up without raising dust, using methods that avoid airborne particles; collect in suitable containers for disposal or reuse
Other Advice: Wash spill areas with water to remove residual particles, but avoid making surfaces slippery
Handling: Minimize dust creation, use in well-ventilated spaces; avoid eating, drinking, or smoking during use
General Hygiene: Wash hands with soap and water after handling; remove contaminated clothing and launder before reuse
Storage Conditions: Store in tightly closed containers in dry, cool, well-ventilated locations away from moisture and incompatible substances like hydrofluoric acid
Container Advice: Use moisture-resistant packaging; check containers regularly for integrity; keep off floor to prevent moisture ingress in humid areas
Occupational Exposure Limits: OSHA PEL for amorphous silica 20 mppcf (million particles/ft3), ACGIH TLV 10 mg/m3 (inhalable fraction), 3 mg/m3 (respirable)
Engineering Controls: Use local exhaust or general room ventilation; employ closed systems if high levels of dust may be generated
Personal Protective Equipment: Dust mask or respiratory protection if dust is present; safety glasses or goggles; latex or nitrile gloves for prolonged handling
Environmental Exposure: Regular monitoring of airborne dust levels in workplace, good housekeeping practices to minimize dust accumulation
Appearance: White to off-white granular or beaded solid, can be transparent to slightly cloudy
Odor: Odorless
pH (in suspension): 4–8
Melting/Freezing Point: Not applicable (decomposes at >1600°C)
Boiling Point: Not applicable
Solubility in Water: Insoluble
Vapor Pressure: Not volatile
Bulk Density: 0.6–0.8 g/cm3 depending on bead size
Other Properties: Pore volume, surface area and specific adsorption characteristics define water absorption performance
Chemical Stability: Stable under standard conditions; moisture may cause gradual decline in desiccant performance
Reactivity: Non-reactive with most substances; avoid exposure to hydrofluoric acid, strong bases and strong oxidizers
Hazardous Decomposition Products: None identified under normal use or storage conditions
Conditions to Avoid: Contact with acids or strong bases, excessive moisture, temperature extremes, or exposure to strong oxidizers
Acute Toxicity: Silica gel considered non-toxic when ingested in small quantities; bulk ingestion can cause digestive discomfort
Skin Contact: Slight irritation possible in sensitive individuals
Eye Contact: Mechanical irritation (redness, watering) expected with dust exposure
Chronic Exposure: No known long-term adverse health effects from amorphous silica gel; crystalline silica dust not normally present in product
Sensitization: Not known to produce allergic reactions
Carcinogenicity: IARC and NTP classify amorphous silica as not classifiable as to carcinogenicity to humans; crystalline silica (not present) is a known human carcinogen
Aquatic Toxicity: Not toxic to aquatic organisms; product is insoluble, settles out of water
Persistence and Degradability: Chemically and physically stable, not biodegradable, persists in the environment as inert mineral
Bioaccumulative Potential: Not bioaccumulative
Mobility in Soil: Low mobility due to insolubility and adsorption to soil or sediment
Other Effects: Large spills may create localized pH changes due to adsorption of moisture, but broad ecological impact is considered minimal
Product Disposal: Dispose as non-hazardous solid waste, in accordance with national and local regulations; avoid dispersing large quantities to natural water bodies
Packaging Disposal: Rinse and discard packaging with other industrial waste, unless contaminated with dangerous substances
Recycling Opportunities: Used silica gel may be regenerated by heating and reused for drying applications; check local guidance for industrial recycling possibilities
Special Considerations: Contact local waste authority for advice on large-scale or industrial disposal scenarios
UN Number: Not regulated for transport
Hazard Class: Not classified as dangerous goods
Packing Group: Not assigned
Shipping Name: Silica Gel
Transport Labels: None required
Special Precautions: Ensure containers are well closed, protected from moisture uptake during transit, avoid pigment-impregnated materials mixing with food goods in shipment
EU Regulations: Not subject to registration under REACH due to naturally occurring, non-chemically modified mineral status
US Regulations: Listed on TSCA inventory; not subject to workplace-specific reporting or hazardous categorization under OSHA or SARA Title III
Labeling Requirements: Product labels must reflect hazard classification, precautionary advice, and contact information
Other Standards: Food-grade silica gel must comply with FDA and EFSA purity standards if used in applications involving packaging or storage of consumables
Workplace Guidance: Employers must provide safety training related to dust hazards, personal protective equipment and safe handling procedures as part of standard workplace safety protocols
