Inhalation: Remove to fresh air, keep victim comfortable and under observation, seek medical attention if symptoms like dizziness, headache, or nausea happen
Skin Contact: Remove contaminated clothing immediately, wash skin thoroughly with soap and water, flush for at least 15 minutes, seek medical help if irritation develops
Eye Contact: Flush eyes with plenty of water for at least 15 minutes, lift eyelids regularly, consult ophthalmologist for ongoing irritation
Ingestion: Rinse mouth, do not induce vomiting, drink water if alert, seek medical supervision without delay
Symptoms of Exposure: Redness, irritation, burning sensation, nausea, confusion, headache, gastrointestinal distress
Suitable Extinguishing Media: Dry powder, carbon dioxide, foam, do not use direct water jets
Specific Hazards: Produces toxic vapors including tin oxides and carbon monoxide under fire conditions, high vapor densities can travel and ignite at a distance
Protective Equipment: Use full-face self-contained breathing apparatus, chemical-resistant suit
Fire-Fighting Procedures: Evacuate area, cool nearby containers with water spray, contain and collect runoff
Fire Characteristics: Flammable, may form explosive mixtures in air
Personal Protection: Don suitable gloves, chemical goggles, face shield, and protective clothing
Evacuation: Evacuate non-essential personnel, ventilate area
Containment Methods: Stop leak if safe, prevent entry into drains, sewers, or water bodies
Cleanup Procedures: Absorb with sand or inert absorbent, transfer residue to labeled chemical waste drums, wash down contaminated surfaces avoiding runoff into the environment
Environmental Precautions: Notify authorities if risk of contamination exists, follow up with remediation as necessary
Handling: Work in well-ventilated fume hoods, avoid inhaling vapors, prevent skin and eye contact at all times, employ proper transfer techniques to minimize spillage and vapor generation
Storage: Store in tightly closed containers made of compatible materials, keep away from heat, sparks, open flame, and oxidizers, maintain in a cool, dry, well-ventilated space, segregate from acids and strong oxidants
Incompatible Materials: Strong oxidizing agents, acids, halogens
Special Precautions: Use grounding and bonding protection for pumping and decanting, keep storage containers clearly labeled and checked regularly for leaks
Occupational Exposure Limit (OEL): ACGIH TLV for organic tin compounds: 0.1 mg/m³ (as Sn)
Engineering Controls: Use fume hoods, local exhaust ventilation, flame and explosion-proof equipment
Personal Protection: Wear chemical-resistant gloves (nitrile, neoprene), protective splash goggles, laboratory coat or chemical apron, closed footwear
Respiratory Protection: Suitable NIOSH/MSHA-approved organic vapor respirator when handling away from ventilation
Hygiene Measures: Wash hands and face before breaks and after handling, prohibit food, drink, or smoking in areas using tetraethyltin
