First Aid Measures

Eye Contact: Gently rinse with water for several minutes; remove contact lenses if present and easy to do; seek attention if irritation persists
Skin Contact: Wash with soap and plenty of water; obtain medical advice for persistent irritation
Inhalation: Move to fresh air; support breathing if needed; consult a physician if symptoms develop
Ingestion: Rinse mouth thoroughly; drink water; do not induce vomiting unless directed by medical personnel; seek medical help if ill effects develop
Advice to Physicians: Treat symptomatically; no antidote required

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Hazards from Combustion: Not combustible; substance itself does not burn, but containers may explode under extreme heat due to pressure build-up
Firefighting Instructions: Stay upwind; avoid contact with product; wear self-contained breathing apparatus and protective clothing
Flash Point: Not applicable
Explosion Limits: Not applicable

Accidental Release Measures

Personal Precautions: Wear dust mask, safety goggles, and gloves; avoid inhalation and contact with skin or eyes
Environmental Precautions: Prevent entry to drains, sewers, and watercourses
Methods for Cleanup: Avoid creating dust; sweep up or vacuum using equipment fitted with HEPA filter; place in appropriate waste container; ventilate area; wash spill site after material pickup

Handling and Storage

Handling: Operate in well-ventilated spaces; avoid generating dust; use proper personal protective equipment; keep containers tightly closed
Storage: Store in cool, dry, and well-ventilated area; keep away from incompatibles such as strong acids, bases, and oxidizing agents; containers should be clearly labeled and protected from damage

Exposure Controls and Personal Protection

Exposure Limits: OSHA PEL: 2 mg/m³ (as tin), ACGIH TLV: 2 mg/m³ (as tin)
Engineering Controls: Use local exhaust ventilation for dusty operations
Personal Protective Equipment (PPE): Wear safety glasses with side shields, gloves resistant to chemicals, and long-sleeved clothing; in high dust scenarios, wear a NIOSH-approved respirator
Hygiene Measures: Wash hands after handling; remove contaminated clothing and wash before reuse; avoid eating, drinking, or smoking in work area

Toxicological Information

Acute Toxicity: Not classified as acutely toxic; minimal evidence for oral, dermal, or inhalation toxicity in laboratory studies
Chronic Effects: Prolonged exposure to dust may cause mild respiratory irritation or produce benign pneumoconiosis
Carcinogenicity: Not considered a carcinogen by IARC, NTP, or OSHA
Mutagenicity: No mutagenic effects reported
Reproductive Toxicity: No evidence for reproductive or developmental toxicity
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion

Ecological Information

Persistence and Degradability: Inorganic material, does not biodegrade
Bioaccumulation Potential: Not expected to bioaccumulate in aquatic organisms due to low solubility
Mobility in Soil: Low mobility, remains in solid phase
Aquatic Toxicity: No known toxicity to aquatic life at normal concentrations
Other Adverse Effects: Avoid large releases to prevent physical accumulation in water or soil environments

Disposal Considerations

Waste Disposal Methods: Dispose according to local, state, and federal regulations; landfilling permitted under most jurisdictions for non-hazardous solids
Contaminated Packaging: Empty containers should be cleaned before reuse or disposal; packaging waste managed as industrial waste
Reuse/Recycle Options: Recover and recycle if possible; material can often be reprocessed for industrial uses

Transport Information
