Label Elements: Warning sign, exclamation mark icon
Hazard Statements: Causes mild eye irritation, may cause an allergic skin reaction, may cause respiratory irritation if handled improperly
Precautionary Statements: Avoid breathing dust and fumes; wash hands thoroughly after handling; wear protective gloves and eye protection
Routes of Exposure: Inhalation, skin contact, ingestion
Most Important Symptoms: Itching, redness, mild cough, sneezing
Chemical Identity: Proprietary organotin compound blend
Main Ingredients: Methyl tin mercaptide (CAS: 57583-35-4, 25–35%), Organic stabilizer additives (proprietary, 60–70%), Lubricants, fillers and processing aids
Impurities Contributing to Hazard: Trace amounts of methyl mercaptan
Mixture or Substance: Mixture
Physical Form: White to off-white powder or granular substance
Inhalation: Move affected person to an area with fresh air right away; keep breathing normally; contact medical staff if irritation or symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin with running water and mild soap, avoid harsh scrubbing, seek medical advice if rash or redness occurs
Eye Contact: Flush eyes gently under flowing water for at least 15 minutes, lift upper and lower eyelids occasionally, avoid rubbing eyes, get medical attention for lingering symptoms
Ingestion: Rinse mouth, do not induce vomiting, offer water to dilute if conscious, take the person to the nearest clinic or hospital
Note for Physicians: Treat symptoms based on clinical judgment; no antidote available
Suitable Extinguishing Media: Water spray, foam, carbon dioxide (CO₂), dry chemical powder
Unsuitable Extinguishing Media: High-volume water jets
Hazards from Combustion: Releases carbon monoxide, tin oxides, sulfur oxides, organic vapors, hydrogen chloride on burning
Special Protective Equipment: Firefighters need full protective gear, self-contained breathing apparatus
Firefighting Advice: Move containers from fire area if possible without risk, cool closed containers near flames
Explosion Hazard: Risk exists if dust builds up and ignites
Personal Precautions: Wear gloves, goggles, dust mask, avoid contact with skin and eyes, ventilate area if dust present
Environmental Precautions: Prevent product from reaching drains, surface water, or soil
Methods for Containment: Collect spilled material in sealable containers using non-sparking tools, use damp cloths to minimize dust
Cleanup Procedures: Clean remaining traces with water, avoid dry sweeping, dispose of as hazardous waste
Large Spills: Notify authorities as required by regulations
Handling: Use in well-ventilated spaces, keep containers closed, prevent dust generation, avoid contact with skin and eyes, do not eat or drink during use
Storage: Store in original packaging, in cool, dry, well-ventilated space out of direct sunlight, separate from food and incompatible chemicals (acids, oxidizers)
Storage Temperature: Maintain below 30°C for maximum stability
Specific Storage Risks: Moisture causes product caking and degradation, strong odor emerges if exposed to high temperature
Occupational Exposure Limits: TWA (as tin): 0.1 mg/m³
Engineering Controls: Local exhaust ventilation, enclosures for dusty processes, use of explosion-proof electrical systems
Personal Protective Equipment: Chemical safety goggles, impervious gloves (nitrile or PVC), long-sleeve clothing, respiratory protection (dust mask or P2 filter)
Hygiene Measures: No eating, drinking, smoking in handling areas; hands washed before meals or after handling
Environmental Controls: Collect wash water resulting from process spills, avoid discharge to sewers
Appearance: White or pale yellow powder
Odor: Mild sulfurous scent
Odor Threshold: Not established
pH: Not soluble in water, no pH value available
Melting Point/Freezing Point: >120°C
Boiling Point: Not relevant (decomposes before boiling)
Flash Point: >200°C (closed cup, estimated)
Evaporation Rate: Not applicable
Flammability: Not easily flammable
Vapor Pressure: Negligible at room temperature
Relative Density: 1.25–1.35 g/cm³
Solubility: Insoluble in water, soluble in aromatic hydrocarbons
Partition Coefficient n-octanol/water: Not available
Auto-Ignition Temperature: Not determined
Decomposition Temperature: >200°C
Viscosity: Not applicable
Chemical Stability: Stable under normal use and storage conditions
Reactivity: Not reactive at room temperature, but reacts strongly with acids, oxidizers, strong bases
Hazardous Decomposition: Produces tin oxides, carbon monoxide, hydrogen sulfide, chloride fumes during decomposition
Incompatible Materials: Exposure to acids, strong oxidizers or reducing agents leads to potentially hazardous reaction
Conditions to Avoid: Moisture, strong heat, direct sunlight, dust buildup
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Toxicity: LD50 (oral, rat) >2000 mg/kg
Skin Corrosion/Irritation: Mild irritant
Serious Eye Damage/Irritation: Causes mild eye discomfort
Respiratory/Skin Sensitization: Sensitizer for certain individuals
Chronic Effects: Repeated skin contact may cause allergic dermatitis
Carcinogenicity: No components listed as carcinogenic by IARC, NTP, OSHA
Mutagenicity: No evidence found in existing data
Other Health Effects: Overexposure may lead to headaches, dizziness, respiratory irritation
Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in aquatic environments (LC50 96hr - fish: 5–15 mg/L, EC50 Daphnia 10–20 mg/L)
Persistence and Degradability: Low biodegradability, tends to persist in sediments
Bioaccumulation Potential: Moderate, due to organotin content
Mobility in Soil: Binds to soil particles, low leaching potential
Other Harmful Effects: Releases tin compounds and sulfur compounds when degraded, which can be toxic to the environment
Waste Disposal Methods: Dispose as hazardous chemical waste using licensed facility; do not dump in drains, waterways, or ground
Contaminated Packaging: Rinse containers thoroughly, offer for recycling if possible, otherwise dispose as per local regulations
Disposal Regulations: Follow local, regional, national, and international guidelines; check waste codes for organotin compounds
Further Caution: Keep waste away from incompatible materials during storage and transport
UN Number: 3077
Proper Shipping Name: Environmentally hazardous substance, solid, n.o.s. (contains organotin compound)
Transport Hazard Class: 9 (Miscellaneous Dangerous Substances)
