Eye Contact: Rinse immediately with plenty of water for at least 15 minutes. Remove contact lenses. Get medical attention if irritation persists.
Skin Contact: Wash off with soap and water, rinse off dust particles. Seek medical advice if irritation develops.
Inhalation: Move person to fresh air. Blow nose gently, rinse mouth. Seek attention if coughing or discomfort continues.
Ingestion: Rinse mouth with water. Drink water to help clear particles from throat. Rarely causes harm, but consult doctor if large quantities swallowed or symptoms develop.
Most Important Symptoms: Eye and upper airway discomfort. Medical observation generally not necessary unless symptoms are severe.
Suitable Extinguishing Media: Product itself is non-flammable. Use water spray, foam, CO₂, or dry powder on surrounding materials.
Specific Hazards During Fire: Product does not burn or support combustion. Heating in fire can generate traces of crystalline silica.
Protective Equipment: Firefighters wear self-contained breathing apparatus in confined space. Standard protective gear.
Hazardous Combustion Products: None. Silica gel produces no hazardous fumes. Dust may become airborne.
Firefighting Precautions: Contain run-off from fire control to prevent environmental contamination.
Personal Precautions: Avoid inhaling dust. Wear safety goggles, masks, gloves.
Environmental Precautions: Prevent material from entering drains in dust form. Sweep up to minimize dust generation.
Methods for Clean-up: Use damp sweeping or HEPA-filter vacuum to limit dust. Wipe with wet cloths, dispose of in suitable containers.
Spill Response: Small spills—sweep and transfer to waste containers. Large spills—eliminate ignition sources, ventilate area.
Protection for Cleaners: Recommend use of NIOSH-approved dust mask in enclosed spaces.
Precautions for Safe Handling: Work in well-ventilated area. Minimize dust, avoid contact with eyes. Use local exhaust if dust produced.
Hygiene Measures: Wash hands before eating, drinking, or smoking. Avoid using compressed air to clean equipment.
Storage Recommendations: Store in original containers, tightly sealed. Keep dry and away from incompatible materials.
Incompatibilities: Hydrofluoric acid reacts with silica; avoid co-storage.
Storage Temperature: Store at room temperature, away from moisture.
Packaging: Reseal opened containers promptly to prevent contamination or absorbing moisture.
Exposure Limits: OSHA PEL for amorphous silica: 20 mppcf (6 mg/m³). ACGIH TLV: 10 mg/m³ (inhalable), 3 mg/m³ (respirable)
Engineering Controls: Use local exhaust ventilation or general room ventilation to keep airborne dust below allowable limits.
Personal Protective Equipment: Safety glasses, dust mask or respirator (NIOSH-approved), gloves to protect skin
