Personal Precautions: Use personal protective equipment, avoid skin and eye contact, dust inhalation
Environmental Precautions: Prevent runoff to waterways, soil, and drains
Methods for Clean-up: Mechanically collect spillage, place in appropriate containers for disposal, wash spill area with water while preventing entry to sewers
Notification: Inform authorities if large releases are likely to reach environment
Handling: Work in well-ventilated areas, minimize dust generation, avoid breathing vapors or mist, wash hands after use

Skin Corrosion/Irritation: Can irritate skin on prolonged or repeated contact
Eye Damage/Irritation: Causes irritation to eyes
Respiratory or Skin Sensitization: No known sensitization reported, though dust may aggravate asthma
Chronic Toxicity: Prolonged exposure may affect kidney, liver, and gastrointestinal tract due to tin accumulation
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, OSHA
Mutagenicity: No evidence in available studies
Reproductive Toxicity: No evidence or reports of reproductive toxicity from occupational exposure
Aquatic Toxicity: Harmful to aquatic organisms, may cause long-term adverse effects in aquatic environment
Persistence and Degradability: Inorganic compound, does not undergo biological degradation, tin species may persist
Bioaccumulative Potential: Potential for accumulation of tin in aquatic species
Mobility in Soil: High water solubility leads to significant mobility
Other Ecological Effects: Avoid discharge to natural waters, small quantities concentrated through food chain may present risk to wildlife
