Information for Physician: Atropine or pralidoxime may be necessary, monitor cholinesterase activity, supportive therapy as necessary
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, do not use direct water stream
Specific Hazards: Emits toxic fumes including oxides of phosphorus, nitrogen, and sulfur under fire, risk of contamination to water sources
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear
Special Procedures: Approach fire from upwind, prevent chemical runoff, avoid inhalation of combustion byproducts
Personal Precautions: Evacuate area, avoid dust generation, ventilate area, prevent unprotected persons from entering
Protective Equipment: Nitrile gloves, chemical-resistant suit, goggles, face shield, approved respirator
Environmental Precautions: Prevent run-off into sewers, waterways, soil; notify environmental authorities if large spill occurs
Cleanup Methods: Absorb with inert material (sand, earth, vermiculite), avoid raising dust and vapors, collect and place into sealed containers for disposal, flush spill area with soap and water solution while containing effluent
Safe Handling: Work in chemical fume hood, avoid inhalation, ingestion, skin, and eye contact, minimize exposure, keep containers tightly sealed
Storage Conditions: Store in cool, dry, well-ventilated place, away from incompatible substances such as strong oxidizers and bases, maintain label integrity
Incompatible Materials: Avoid storage near food, feed, acids, alkalis, oxidizers
Packing Requirements: Use clearly labeled, tightly closed chemical-resistant containers; secondary containment recommended for larger volumes
Engineering Controls: Fume hood, local exhaust ventilation, safety showers, eye-wash stations required
Personal Protective Equipment: Nitrile or butyl rubber gloves, full-sleeved lab coat, chemical splash goggles, face shield for large quantities; use only approved respirator for potential vapor or dust exposure
Exposure Limits: Specific occupational exposure limits not established, apply stringent chemical safety guidelines, minimize duration and frequency of exposure
Hygiene Measures: Do not eat, drink, or smoke during handling, wash thoroughly after use
Physical State: Liquid or crystalline solid (depends on purity and ambient conditions)
Color: Off-white to pale yellow
Odor: Pungent, characteristic of organophosphates
pH: Not applicable in anhydrous state
Melting Point: Data not widely published; estimated 25-40°C (literature varies)

Conditions to Avoid: Prolonged exposure to heat, moisture, direct sunlight, ignition sources, incompatible materials
Potential Routes of Exposure: Ingestion, inhalation, skin absorption, eye contact
Acute Toxicity: Extremely toxic; LD50 (oral, rat) estimated <5 mg/kg
Chronic Effects: Repeated exposure may lead to nerve damage, neurological effects, cholinesterase inhibition, respiratory depression, possible fatality
Symptoms of Overexposure: Headache, vomiting, sweating, numbness, confusion, convulsions, respiratory distress, pinpoint pupils, blurred vision
Sensitization: Risk of skin and respiratory sensitization
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Long-term effects not sufficiently studied; treat as possible risk until more data available
Acute Ecotoxicity: High toxicity to fish, aquatic invertebrates, birds; may cause mortalities at low concentrations
Persistence and Degradability: Slow degradation in environment; breakdown products may remain hazardous
Bioaccumulation: Potential to accumulate in organisms due to moderate to high partitioning
Soil Mobility: Potential for leaching depending on soil properties; strong binding to organic matter possible
Aquatic Toxicity: Expected to cause toxic effects on aquatic environments at trace levels
Other Environmental Hazards: Not volatile under normal conditions, but improper disposal may severely harm local ecosystems
Waste Disposal Methods: Collect residues in sealed, labeled containers; subject all material to hazardous waste disposal regulations; incinerate at authorized facility capable of handling organophosphates
Contaminated Packaging: Treat empty containers as hazardous; triple rinse with appropriate solvent, destroy to prevent reuse, dispose according to local regulations
Do Not: Release into the environment or public landfills; avoid incineration in open fires
