Specific Hazards: Product is non-flammable and non-combustible; may emit fine dust in dry conditions
Special Protective Equipment: Firefighters should wear standard protective equipment, dust mask or respiratory protection if large volumes of dust form
Combustion Products: None hazardous; may produce minor amounts of silicon oxides at very high temperatures
Personal Precautions: Use personal protective equipment to avoid breathing dust and skin contact; ventilate area
Spill Cleanup Methods: Scoop or shovel material into appropriate container, avoid generating unnecessary dust, wash area with water after material has been removed
Environmental Precautions: Prevent large amounts from entering drains, surface water, or sewers
Disposal: Collect spillage in sealable containers for proper disposal
Handling: Avoid breathing dust, avoid contact with eyes and prolonged contact with skin, practice good hygiene, ensure proper ventilation in work area
Storage Conditions: Store in a cool, dry, well-ventilated area, keep container tightly closed when not in use, protect from moisture
Incompatible Materials: Strong acids, hydrofluoric acid
Safe Handling Advice: Handle with care to prevent spills and dust release
Occupational Exposure Limits: OSHA PEL for respirable crystalline silica (not applicable for amorphous silica gel): 0.05 mg/m³; ACGIH TLV: 10 mg/m³ (total dust), 3 mg/m³ (respirable fraction)
Engineering Controls: Provide general or local exhaust ventilation as needed to minimize dust levels
Personal Protective Equipment: Use eye protection (goggles or safety glasses) if handling large quantities or in dusty conditions, dust mask or respirator in poorly ventilated areas, gloves for sensitive skin
Hygiene Measures: Wash hands thoroughly after handling, avoid eating or drinking near product
Appearance: White or off-white granules or beads, semi-transparent

Chemical Stability: Stable under recommended storage and handling conditions
Possibility of Hazardous Reactions: None under normal use
Conditions to Avoid: Strong acids, especially hydrofluoric acid, which can react with silica
Hazardous Decomposition Products: Silicon tetrafluoride (with hydrofluoric acid), otherwise none expected
Reactivity: Unreactive with common materials
Acute Toxicity: Low toxicity by ingestion, inhalation, or skin contact based on animal and human data
Skin Corrosion/Irritation: May cause mild mechanical irritation
Eye Damage/Irritation: May cause temporary irritation if dust enters eyes
Chronic Effects: Long-term exposure to respirable crystalline silica dust can cause silicosis, but amorphous silica gel presents minimal risk when used as directed
Sensitization: Not known to cause skin or respiratory sensitization
Carcinogenicity: Not classified as carcinogenic; amorphous silica is not listed by IARC or NTP
Mutagenicity: No evidence in current literature
Reproductive Toxicity: No evidence in current literature
Ecotoxicity: Not expected to be toxic to aquatic or terrestrial organisms
Persistence/Degradability: Chemically inert, does not biodegrade but can disperse in environment as an inert mineral
Bioaccumulation: Does not bioaccumulate
Mobility in Soil: Insoluble, remains on soil surface or settles in sediment
Other Adverse Effects: No significant adverse environmental effects expected from normal consumer use or small releases
Waste Disposal Methods: Dispose as non-hazardous solid waste in accordance with local, state, and national regulations
