Product Name: Big Wide Pore Silica Gel
Chemical Name: Silicon Dioxide, Amorphous
CAS Number: 7631-86-9
Recommended Uses: Adsorbent, desiccant, catalyst support
Supplier Information: Full address, phone number, and emergency contact for the manufacturer or distributor must be clearly listed on every container; workers tend to look for these details in a hurry during workplace emergencies.
Emergency Phone Number: Always 24-hour access for accidental exposure or incidents involving spills.
Classification: Not classified as hazardous under GHS, although fine dust calls for vigilance.
Physical Hazards: Can cause eye and respiratory irritation, especially with powders.
Health Hazards: Inhalation may cause coughing, sneezing, or aggravate asthma; dry skin contact leads to roughness or minor irritation; ingestion is generally non-toxic in small amounts, but product should never be consumed.
Environmental Hazards: Not known to be dangerous in soil or water, yet high releases can change local conditions for aquatic life due to high absorption capacity.
Warning Pictograms: None required.
Signal Word: None.
Chemical Identity: Amorphous Silicon Dioxide
Synonyms: Silica Gel, Silicon Dioxide Gel
Content: More than 99% pure SiO₂
Impurities: Trace elements such as sodium, aluminum, or calcium may appear but rarely exceed 1%.
Other Additives: No additives or binders expected; coloring agents used for indicating gels should be separately identified.
Inhalation: Shift person to fresh air promptly—often enough, dust gets in during transfer or filling. Persistent coughing means checking with a health professional.
Skin Contact: Rinse with water and mild soap to prevent drying out.
Eye Contact: Flush with large amounts of water and pull eyelids apart to ensure removal of dust particles; avoid rubbing.
Ingestion: Give a glass of water to drink. No vomiting needed unless significant discomfort arises.
Further Medical Attention: For any ongoing symptoms, especially for sensitive or asthmatic individuals, a doctor’s advice always makes sense.
Flammability: Product does not burn but containers may melt in fire.
Extinguishing Media: Use any available firefighting material—water spray, foam, dry powder, or CO₂ all work.
Special Hazards from Combustion: Decomposition does not generate dangerous fumes; main risk is from heated containers or surrounding materials.
Firefighting Advice: Standard protective gear for fire personnel is usually enough; avoid inhaling unknown smoke.
Explosion Risk: None under normal conditions.
Personal Protection: Wear dust mask and safety goggles, keep hands protected with gloves; ventilation is helpful even for low-dust granules.
Spill Management: Collect with shovel, dustpan, or industrial vacuum—don’t sweep dry if fine dust is present.
Environmental Precautions: Avoid flushing large spills into drains; scoop and bag material for reuse or disposal.
Cleanup Guidance: Wet down dusty residues to stop airborne particles. Good housekeeping matters for slip risk reduction.
Handling: Pour and move in a way that minimizes dust; stick to enclosed transfer where possible.
Personal Hygiene: Wash hands after completing work. Store food and drinks well away from the substance.
Storage: Keep in airtight containers or sealed drums, in a dry and cool spot. Label all storage drums or bags with content and hazard details.
Storage Temperature Limits: No strict temperature requirement, but less humidity preserves effectiveness.
Incompatibility: Avoid storing near hydrofluoric acid, strong bases, or sources of contamination.
Occupational Exposure Limits: Typical limit for amorphous silica dust falls under 10 mg/m³ (inhalable) as an 8-hour TWA.
Ventilation: General ventilation keeps dust out of breathing zones. Local exhaust extraction smart near filling or blending lines.
Personal Protective Equipment: Gloves (nitrile or similar), dust goggles, and P2 (N95) masks in areas of airborne dust, lightweight lab coats in routine work.
Respirator Use: Required if visible dust clouds form or for bulk handling/shoveling in enclosed spaces.
General Hygiene Controls: No eating or drinking in work areas, and always keep wash stations nearby.
Appearance: White, translucent to opaque granules or beads, sometimes large-pored with high surface area.
Odor: None.
pH: Neutral (6–7 in water suspension).
Melting Point: Exceeds 1500°C.
Boiling Point: Not applicable, as the material does not boil under normal conditions.
Flash Point: Not relevant.
Solubility: Insoluble in water and common solvents.
Bulk Density: Typically ranges 400–800 kg/m³.
Molecular Weight: About 60.08 g/mol.
Porosity: Pore diameter as specified for wide pore types, often between 60–150 angstroms or more.
Chemical Stability: Very stable in dry storage—even after years, shows little degradation.
Reactivity: Unreactive toward most chemicals, but gets attacked by strong hydrofluoric acid.
Possibility of Hazardous Reactions: No hazard under normal use.
Conditions to Avoid: Prolonged exposure to acids like hydrofluoric, soaking or flooding that reduces adsorption power.
Incompatible Materials: Strong alkalis, hydrofluoric acid.
Hazardous Decomposition Products: None under normal temperatures and pressures.
Possible Exposure Routes: Inhalation, skin and eye contact, accidental ingestion.
Acute Effects: Short-term overexposure leads to irritation of eyes, throat, or skin; coughing happens with significant dust.
Chronic Effects: Non-crystalline (amorphous) silica does not carry the lung fibrosis or silicosis risk associated with crystalline forms.
Carcinogenicity: Amorphous silica not classified as carcinogenic by IARC or OSHA.
Sensitization: No evidence for allergic reaction or sensitization in workers handling this on a regular basis.
Mutagenicity/Teratogenicity: No reported effects.
Medical Conditions Aggravated by Exposure: Individuals with chronic respiratory trouble or asthma may notice more symptoms with repeated dust exposure.
Aquatic Toxicity: Not harmful to aquatic animals under normal use.
Persistence and Degradability: Highly persistent, does not break down or dissolve in the environment.
Bioaccumulation Potential: None; does not bioaccumulate.
Soil Mobility: Remains at point of release; no movement through soil or water expected.
Additional Environmental Notes: The product poses no risk to compost, landfill, or wastewater treatment when volumes are limited.
Waste Treatment Methods: Dispose of as non-hazardous solid waste if free from contaminants; reuse as appropriate for industrial drying or absorption recovery.
Disposal Containers: Strong, sealed bags or drums; regular industrial waste process works.
Recycling: Regeneration and reuse possible in many drying applications.
Landfill Guidance: Safe for landfill, provided it hasn’t been contaminated with hazardous substances during use.
Incineration: Not required or recommended; material won’t combust or break down by burning.
Local Regulations: Follow local, regional, and national regulations—the specifics sometimes call for record-keeping in certain industries.
UN Number: Not assigned; product not considered hazardous for transport.
Proper Shipping Name: Silica Gel
Transport Hazard Class: Not regulated.
