Inhalation: Remove to fresh air, keep person calm, and seek medical advice if symptoms persist. Give oxygen if breathing is difficult.
Skin Contact: Remove contaminated clothing and thoroughly wash skin with soap and water. Seek attention for irritation or allergic reaction.
Eye Contact: Rinse immediately with gently flowing water for at least fifteen minutes, keeping eyelids open. Medical attention is important to prevent injury.
Ingestion: Do not induce vomiting unless directed by medical personnel. Rinse mouth with water, and seek urgent care. Activated charcoal may be recommended in certain cases.
Principal Symptoms: Digestive upset, respiratory distress, nervous system effects such as tremors and drowsiness, eye and skin irritation.
Advice to Physician: Symptomatic treatment; consult poison center for specific carbamate antidotes, such as atropine sulfate for cholinesterase inhibition.
Suitable Extinguishing Media: Use water fog, foam, dry powder, or carbon dioxide for small fires. Large fires may benefit from sprayed water to cool exposed drums.
Hazards From Combustion: Generates toxic and irritating fumes such as nitrogen oxides, carbon monoxide, and potentially isocyanate compounds. Runoff may be hazardous.
Protective Equipment: Full bunker gear and positive-pressure self-contained breathing apparatus for responders.
Special Precautions: Avoid direct stream on burning liquid to prevent further spread of toxic vapors.
Explosion Risk: Containers exposed to heat may burst. Keep away from all ignition sources.
Personal Precautions: Wear chemical resistant gloves, coveralls, goggles, and respirators if vapor or mist present. Prevent contact with skin, eyes, and clothing.
Environmental Precautions: Contain spillage, prevent entry into drains, sewers, or waterways, and avoid contamination of soil and vegetation.
Clean-up Methods: Use inert absorbent (sand, earth, vermiculite), gather solid waste in suitably labeled containers for disposal. Rinse area with minimal water to reduce environmental burden.
Notification: Report significant spills to local, regional, or national environmental authorities as required.
Safe Handling: Use appropriate chemical-resistant gloves, goggles, clothing, and hierarchies of controls including local exhaust ventilation. Do not eat, drink, or smoke in work area.
Hygienic Practices: Wash thoroughly after handling, especially before meals, breaks, and bathroom use.
Storage Conditions: Keep in original, tightly closed containers, store in cool, dry, well-ventilated areas away from direct sunlight, food, feedstuffs, fertilizers, reducing agents, acids, and bases. Post warning signs in storage zones.
Storage Limitations: Follow stacking and temperature guidelines provided by supplier to prevent caking, degradation, or container rupture.
Incompatibilities: Strong oxidizing agents, acids, bases, and certain metals can react and destabilize the compound.
Occupational Exposure Limits: Manufacturer sets suggested workplace limits; consult country-specific regulations for guidance.
Ventilation: Employ mechanical and/or local ventilation to minimize vapor, aerosol, or dust formation.
Respiratory Protection: Wear particulate or filter respirator (N95 or better) if airborne concentrations are likely to exceed exposure limits or during gross contamination.
Eye Protection: Chemical safety goggles, full-face splash shields where risk of splashing exists.
Hand Protection: Butyl or nitrile rubber gloves to prevent skin absorption.
Body Protection: Chemical-resistant coveralls and boots; change out of contaminated clothing promptly.
Other Protective Measures: Emergency eyewash stations and showers recommended near handling points.
Form: May appear as technical crystalline solid or as liquid in formulated state.
Color: Off-white to tan, varies with formulation.
Odor: Mild, chemical or faintly aromatic.
Melting Point: Approximately 90–105°C, depending on material purity.
Boiling Point: Decomposes before boiling, so direct measurement not practical.
Solubility: Readily dissolves in organic solvents (acetone, methanol), slight solubility in water.
pH (1% Solution): Typically neutral to slightly acidic.
Vapor Pressure: Very low at room temperature.
Density: 1.10–1.20 g/cm³ for technical grade.
Other Properties: Stable when stored in closed containers away from incompatible/damp areas.
Reactivity: Does not react violently under normal, controlled storage and use.
Chemical Stability: Shelf-stable for defined product life if not exposed to excessive moisture or heat.
Hazardous Reactions: Can react with strong oxidizing, reducing agents, acids, or bases, possibly leading to hazardous decomposition.
Hazardous Decomposition Products: Nitrogen oxides, carbon monoxide, carbon dioxide, and possibly acrolein and related irritants. Thermal breakdown at high temperatures releases highly toxic fumes.
Polymerization Risk: Not anticipated under normal conditions.
Routes of Exposure: Inhalation, skin, eye, and oral routes all present risk.
Acute Effects: High oral or dermal exposure may induce symptoms such as headache, muscle weakness, salivation, abdominal pain, twitching, or seizures from cholinesterase inhibition.
Chronic Effects: Long-term exposure may impair nervous system functioning or cause skin sensitization.
LD50 Values: Toxicity values adjusted depending on targeted species and product formulation, typically in rat studies oral LD50 ranges 50–200 mg/kg.
Carcinogenicity: Evidence does not indicate significant carcinogenic risk for this carbamate group.
Other Toxic Effects: Non-carcinogenic chronic risks may include liver and renal function changes.
Acute Aquatic Toxicity: Highly toxic to fish, aquatic invertebrates, and possibly algae; runoff from treated areas into water may cause significant impacts on aquatic habitats.
Persistence and Degradability: Degrades via hydrolysis and microbial action in soil and water, but breakdown products may still pose risks.
Bioaccumulation: Limited bioaccumulation predicted but impact on aquatic food chain should not be underestimated.
Mobility in Soil: Compound may migrate through soils with high water flow or sandy loams, increasing risk of groundwater exposure in vulnerable zones.
Other Environmental Concerns: Bee mortality, bird poisoning, and disruption of beneficial insect populations highlighted in field studies.
Waste Treatment Methods: Small quantities: Dilute and apply to approved, designated disposal areas using label rates. Large spills or residues: Collect in containers for hazardous waste treatment following regional guidelines.
Container Disposal: Triple rinse, puncture, and dispose per national pesticide container rules—never re-use containers for potable or food liquids.
Landfill or Incineration: Authoritative advice varies; high-temperature, controlled incineration preferred under controlled environments designed for chemical waste.
Disposal of Contaminated PPE: Wash reusable gear separately from other laundry; single-use PPE should go in hazardous waste streams.
UN Number: Depends on quantity and formulation; most concentrate products travel as regulated hazardous pesticides.
Proper Shipping Name: Pesticide, Liquid, Toxic, Organic, n.o.s. (including main compound name).
Transport Hazard Class: Usually assigned Class 6.1 (toxic substances) or similar.
