Hazard Identification

Main Health Risks: Eye irritation and skin sensitization reported, especially with repeated or prolonged contact
Environment Risk: Toxic to aquatic life, particularly fish and aquatic invertebrates
Chronic Exposure: No firm evidence in humans, but animal studies point to possible reproductive and developmental effects at high dosing

Composition / Information on Ingredients

Active Ingredient: Hexythiazox (pure or as a technical-grade compound)
Formulation Additives: Wetting agents, solvents or carriers often included in commercial products, but percentages differ
Impurities: Usually trace levels, precise breakdown sometimes not published outside manufacturer safety documentation

First Aid Measures

Inhalation: Move to fresh air, support breathing if necessary, seek medical advice if symptoms persist
Eye Contact: Rinse cautiously with clean water for several minutes, remove contact lenses, keep rinsing eyes
Ingestion: Rinse mouth thoroughly, do not induce vomiting without medical direction, seek medical attention promptly
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water

Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical or carbon dioxide recommended
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, nitrogen oxides, sulfur oxides, hydrogen chloride, and possibly other irritating gases
Personal Protective Equipment: Use self-contained breathing apparatus and protective clothing
Fire Control Recommendations: Keep containers cool by spraying with water, avoid breathing smoke or vapors

Accidental Release Measures

Personal Protection: Gloves, chemical goggles, and protective clothing
Containment: Prevent further leakage if safe, avoid runoff into drains and surface waters
Clean-up Methods: Sweep up spillage without causing dust, place in disposal containers, ventilate area
Decontamination: Wash contaminated surfaces with plenty of water and soap

Handling and Storage

Handling: Minimize dust generation, wear recommended PPE, keep away from food and drink, avoid direct contact
Storage: Store in a cool, dry, well-ventilated area, keep containers tightly closed, separate from incompatible substances such as strong acids
Special Precautions: Do not reuse empty containers, avoid contamination of water sources upon disposal

Exposure Controls and Personal Protection

Occupational Exposure Limits: Not formally established for general workplaces, but local guidelines or recommended levels sometimes apply
Engineering Controls: Local exhaust ventilation commonly used in mixing and loading settings
Protective Equipment: Gloves (nitrile or neoprene), chemical-resistant coveralls, boots, goggles, and where needed, respirators

Physical and Chemical Properties

Physical State: Solid
Color: Off-white or pale yellow
Odor: Mild or none
Melting Point: 108-109°C
Solubility in Water: Practically insoluble; more soluble in organic solvents like acetone
Vapor Pressure: Very low
Density: Approx. 1.45 g/cm³
Partition Coefficient (log Kow): About 2.5-3.3, indicating moderate bioaccumulation potential

Stability and Reactivity

Stability: Generally stable under normal storage and handling conditions
Incompatible Materials: Strong oxidizers, strong acids, and bases
Hazardous Reactions: No hazardous polymerization expected
Degradation: Decomposes at elevated temperatures, or in contact with strong acids or bases

Toxicological Information

Acute Toxicity: Oral and dermal toxicity considered low for humans
Irritation: Mild skin and serious eye irritant in several animal studies
Sensitization: Repeated contact may lead to skin sensitization
Long-term Effects: No conclusive human data, animal research raises concerns for reproductive impacts at high exposure
Carcinogenicity: Not classified as carcinogenic by IARC or US EPA

Ecological Information

Aquatic Hazard: Highly toxic to fish and aquatic invertebrates, can persist in certain environments
Soil Mobility: Low water solubility and moderate soil adsorption, so tends to bind to soil particles
Persistence: Moderate degradation in soil under field conditions, but breaks down faster in high heat or sunlight
Bioaccumulation: Log Kow values suggest possible build-up in aquatic organisms, though extensive data limited

Disposal Considerations

Waste Disposal: Avoid flushing into sewers, watercourses, or natural waters
Recommended Method: Incineration or landfill at approved facilities, complying with local regulations
Triple Rinse: Empty containers should be rinsed three times then punctured or crushed before disposal
Environmental Precautions: Keep waste out of water sources, minimize dust generation during handling of waste

Transport Information

ADR/RID Classification: Not always regulated for overland transport, but this depends on quantity and concentration
Proper Shipping Name: Pesticide, Solid, Toxic, n.o.s., if regulated
Packing Group: III (minor hazard, if regulated)
Label Requirements: Toxic substance label may be required on large shipments

Regulatory Information

US EPA: Registered for agricultural use on listed crops; not allowed for residential uses
EU Status: Included in Annex I of EU Council Directive 91/414/EEC for certain uses
Restrictions: Some countries restrict use due to aquatic toxicity
Worker Protection Standard: PPE, reentry intervals, and application restrictions required under federal law
