MSDS Commentary: Triphenyltin Acetate

Identification

Product Name: Triphenyltin Acetate
Chemical Formula: C20H18O2Sn
Common Use: Fungal pesticide for agriculture, wood preservation and antifoulant in marine paints
Appearance: White crystalline solid with faint odor
Chemical Family: Organotin compound
Synonyms: TPTA, Acetic acid triphenylstannyl ester

Hazard Identification

Acute Hazards: Toxic if swallowed, inhaled or absorbed through skin;
Chronic Hazards: Organotin compounds can impact nervous, immune, and endocrine systems with long-term exposure; reproductive toxicity is possible
Corrosivity: Causes skin and eye irritation, may cause burns
Flammability: Non-flammable in solid form, but may emit toxic fumes when burned
Environmental Risks: High toxicity to aquatic life, persistent and can bioaccumulate

Composition/Information on Ingredients

Main Ingredient: Triphenyltin Acetate (concentration varies by grade, commonly above 95%)
Impurities: Related organotin compounds, minor solvents from manufacturing

First Aid Measures

Inhalation: Remove person from exposure, seek medical attention if symptoms appear, supply fresh air
Skin Contact: Remove contaminated clothing, wash affected skin with plenty of water and soap
Eye Contact: Rinse cautiously for minutes with water, remove contact lenses, continue rinsing and consult a physician
Ingestion: Do not induce vomiting, rinse mouth, get immediate medical help; activated charcoal sometimes given by professionals

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam; avoid using water jets directly
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, tin oxides, organic tin fumes
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and chemical protective clothing
Fire-Fighting Considerations: Contain runoff, avoid exposure to toxic gases, remove containers if safe

Accidental Release Measures

Spill Handling: Evacuate area, ventilate, use personal protective equipment including gloves and respirator
Containment: Prevent product from entering drains or waterways
Cleanup Method: Absorb with inert material like sand or earth, then collect in sealable containers
Disposal: Dispose according to local hazardous waste regulations, decontaminate area

Handling and Storage

Handling: Only open and handle in well-ventilated areas; avoid any contact with skin, eyes, or mucous membranes
Storage: Keep in tightly sealed containers in a cool, dry, and well-ventilated place away from food and incompatible substances like acids and oxidizers
Incompatibilities: Avoid storing with strong acids, oxidizers, and bases to prevent hazardous reactions

Exposure Controls and Personal Protection

Engineering Controls: Work in fume hood or with local exhaust ventilation to prevent inhalation of dust or vapors
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, lab coat, and use respiratory protection where airborne exposure is possible
Occupational Exposure Limits: Keep exposure as low as possible; recognized authorities like OSHA and ACGIH have developed strict thresholds for organotins, but values differ by country

Physical and Chemical Properties

Physical State: Crystalline solid
Color: White to off-white
Odor: Slight, faint odor
Melting Point: Decomposes above 130°C
Solubility: Low solubility in water, soluble in most organic solvents
Vapor Pressure: Low at room temperature
Partition Coefficient: High potential for bioaccumulation

Stability and Reactivity

Chemical Stability: Generally stable under normal conditions
Reactive With: Strong acids, oxidizers, and bases
Decomposition: Produces hazardous fumes of organic tin compounds and acetic acid at elevated temperatures
Polymerization: Not known to occur

Toxicological Information

Acute Toxicity: Oral, dermal and inhalation exposure have caused poisoning symptoms in animal studies, such as convulsions, central nervous system effects, nausea and vomiting
Chronic Toxicity: Documented impacts on immune system, reproductive organs, and hormone function in test animals
Irritation: Eyes and skin can react with inflammation and damage, even at relatively low exposure levels
Carcinogenicity: Not officially classified by IARC, but ongoing research says organotin compounds deserve close scrutiny

Ecological Information

Aquatic Effects: Very toxic, even at low concentrations, to fish and aquatic invertebrates
Bioaccumulation: Tends to build up in sediments and tissues of aquatic organisms, raising concern along food chains
Soil Impact: Persists long-term, slowing breakdown in low-oxygen environments
Birds and Mammals: Exposures in wildlife can stunt growth, disrupt feeding, and interfere with reproduction

Disposal Considerations

Waste Handling: Collection and containment as hazardous chemical waste; avoid landfilling where leaching could pose risks
Disposal Method: Use approved incineration by licensed hazardous waste handlers, since standard treatment plants cannot neutralize organotin compounds
Container Disposal: Triple rinse containers, puncture or crush, then submit for hazardous waste disposal by authorities
Environmental Concerns: Uncontrolled dumping or incineration without emission controls releases toxic tin compounds into the environment

Transport Information

UN Classification: Toxic solid, organic, n.o.s. (contains triphenyltin acetate)
Packing Group: II or III, risk level depends on container size and concentration
Label Requirements: Toxic, marine pollutant markings are required
Transport Precautions: Keep sealed and upright, away from incompatible substances, and report any spills immediately to environmental authorities

Regulatory Information

International Controls: Restricted in many countries for marine use under International Maritime Organization; many territories ban application for antifouling on ships
Domestic Regulation: Subject to hazardous substance rules and pesticide management frameworks
Worker Safety Laws: Occupational exposure controls and mandatory PPE in many industries that use organotins
Reporting Thresholds: Many places require reporting of even small releases due to toxicity to both people and wildlife
Ongoing Review: Regulatory status can shift as new scientific evidence emerges regarding health and environmental impacts, with some agencies phasing out use entirely in sensitive applications
