Inhalation: Move victim to fresh air immediately. Provide artificial respiration if breathing has stopped. Call emergency medical services. Oxygen may be given if difficulty in breathing.
Skin Contact: Remove contaminated clothing. Rinse skin with copious running water for 15 minutes. Seek medical advice. Remove chemical from skin thoroughly.
Eye Contact: Flush eyes with gently flowing water for at least 15 minutes, lifting eyelids. Remove contact lenses if present and easy to do. Get urgent medical attention.
Ingestion: Rinse mouth with water, do not induce vomiting. Keep victim calm and call poison control center or physician at once. Give nothing by mouth to an unconscious person.
Symptoms/Effects, Acute and Delayed: Severe irritation or burns to eyes, nose, throat, and skin; headaches, dizziness, nausea, convulsions, potential loss of consciousness.
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide. Water spray only to cool fire-exposed containers.
Specific Hazards: Tin fumes, carbon monoxide, carbon dioxide, and organic vapors develop under combustion. Fire may produce irritating, corrosive vapors.
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear. Remove sources of ignition and prevent contamination runoff entering drains.
Advice for Firefighters: Fight fire from safe distance or a protected location. Use water spray for cooling, avoid direct contact with released material.
Personal Precautions: Isolate spill area and restrict access. Wear appropriate gloves, face protection, and chemical resistant clothing.
Environmental Precautions: Prevent releases to surface water or drainage systems, avoid soil contamination, alert local environmental authority if spill is significant.
Containment/Cleanup: Cover spill with inert absorbent (sand or vermiculite). Scoop up material, place in non-metal container for disposal. Ventilate area. Wash spill area after collection.
Disposal of Clean-Up Materials: Handle all materials according to local hazardous waste protocols.
Handling: Operate in well-ventilated fume hood. Minimize skin and eye contact. Avoid inhaling dust, vapors, or mist. Keep away from sources of ignition, heat, and incompatible materials.
Storage: Store in tightly sealed containers in a cool, dry, well-ventilated area. Keep away from light. Protect from physical damage and segregate from oxidizing or acidic materials.
Incompatible Materials: Strong oxidizers, acids, alkalis, moisture, chlorinating agents.
Hygiene Measures: Wash hands after handling and before eating or drinking. Change contaminated clothing. No food or beverages in work area.
Engineering Controls: Use chemical fume hood or exhaust ventilation. Local exhaust at points of emission.
Exposure Limits: Triethyltin compounds: ACGIH TLV-TWA 0.1 mg(Sn)/m³, OSHA PEL 0.1 mg/m³ (as tin).
Personal Protective Equipment: NIOSH-approved respirator if exposure likely, chemical splash goggles or face shield, butyl rubber or nitrile gloves, lab coat with closed sleeves, chemical-resistant apron.
Work Practices: Implement eyewash stations and safety showers in areas of use. Prohibit eating, drinking, smoking during use.
Appearance: Colorless or slightly yellow liquid, faint characteristic odor
Boiling Point: 177–180°C at 760 mmHg
Melting Point: Below room temperature
Flash Point: 65–70°C (closed cup)
Vapor Pressure: 0.1 mmHg at 20°C
Solubility: Insoluble in water, miscible with organic solvents (e.g. ether, acetone, benzene)
Density: ~1.36 g/cm³ at 20°C
pH: Not applicable (non-aqueous)
Partition Coefficient (log Kow): Estimated 2.1–3
Auto-Ignition Temperature: Not measured
Chemical Stability: Stable under recommended storage conditions, but reacts with strong oxidizing agents and acids.
Reactivity: May decompose under prolonged exposure to moisture and UV light, generating flammable, corrosive vapors.
Hazardous Reactions: Contact with acids liberates toxic gases. Builds pressure if container is sealed and heated.
Decomposition Products: Ethyl tin compounds, acetic acid, carbon oxides, tin oxides.
Conditions to Avoid: Heat, flames, sparks, static discharge, moisture, direct sunlight.
Acute Toxicity: Oral LD50 (rat): 16 mg/kg. Generates severe systemic toxicity in low doses. Inhaled vapor or dust triggers high toxicity with possible fatal outcomes.
Skin Corrosion/Irritation: Causes burns and tissue destruction with direct contact.
Eye Damage/Irritation: Severe, persistent eye injury with possible permanent damage.
Respiratory Sensitization: Inhalation produces respiratory tract burns, coughing, and difficulty breathing.
Chronic Toxicity: Neurological symptoms (tremors, confusion, ataxia), potential reproductive or developmental effects, kidney and liver impairment seen in animal studies.
Carcinogenicity: No strong human evidence, but related organotin compounds show tumorigenic effects in rodent studies.
Mutagenicity and Teratogenicity: Evidence for genetic damage and developmental toxicity from laboratory tests.
Target Organs: Nervous system, liver, kidneys, reproductive system.
Aquatic Toxicity: Highly toxic to aquatic life (EC50 for Daphnia magna: 0.01–0.1 mg/L). Persistent in the environment with risk of bioaccumulation.
Persistence and Degradability: Not readily biodegradable, toxic breakdown products linger in soil and sediment for extended periods.
Bioaccumulative Potential: Strong tendency to accumulate in food chains, raising environmental risk.
Mobility in Soil: Low to moderate mobility depending on soil composition, but poses long-term risks to groundwater and surrounding systems.
Other Adverse Effects: Disrupts aquatic invertebrates and algae, impacts fish health and development, potentially toxic to birds and mammals consuming contaminated food.
Waste Disposal Methods: Collect and store excess material or contaminated absorbents in labeled hazardous waste drums. Dispose through licensed hazardous waste contractor following local, state, and federal regulations.
Contaminated Packaging: Triple rinse or puncture, then dispose as hazardous waste. Do not reuse empty containers.
Precautions: Do not allow material to enter natural waterways. Avoid discharge to sewer or municipal waste streams.
Regulations for Disposal: Reference EPA Resource Conservation and Recovery Act (RCRA), European Waste Catalogue (EWC) codes for organotin waste.
