Molecular Formula: C10H15OPS2
Other Components: Solvent (if present), may include water, non-hazardous inactive components
Inhalation: Move victim to fresh air, keep person comfortable and at rest, seek medical attention if respiratory symptoms persist
Skin Contact: Remove contaminated clothing, wash exposed skin with soap and plenty of water for at least 15 minutes, seek medical advice for persistent irritation
Eye Contact: Flush eyes cautiously with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do, continue rinsing, seek ophthalmic care
Ingestion: Rinse mouth with water, do not induce vomiting, never give anything by mouth to an unconscious person, seek immediate medical help
Most Important Symptoms/Effects: Nausea, vomiting, headache, respiratory distress, eye and skin irritation
Special Treatment: Symptomatic and supportive care; physicians should monitor for respiratory, hepatic, and renal complications
Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam, do not use water jets directly on fire
Special Hazards: Fire releases toxic fumes including phosphorus oxides, sulfur oxides, carbon monoxide, carbon dioxide
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear, control runoff water, containers exposed to fire may explode from pressure build-up
Combustion Products: Irritating and highly toxic gases, including oxides of phosphorus, sulfur compounds, aromatic hydrocarbons
Explosion Risk: Vapor/air mixtures can be explosive above flash point
Personal Precautions: Evacuate area of non-essential personnel, ventilate area, wear appropriate chemical-resistant gloves, goggles, protective clothing
Environmental Precautions: Prevent release to drains, surface water, and soil, dike area if needed, report significant release to regulatory agencies
Methods for Clean-up: Absorb spill with inert material like sand or earth, shovel into suitable closed container for disposal, wash spill area with soap and water, ventilate effectively
Disposal of Collected Material: Follow local, national, and international disposal regulations as contaminated waste
Precautions for Safe Handling: Minimize dust, vapor, and mist formation, avoid direct contact with skin and eyes, wash hands thoroughly after handling, no eating, drinking, or smoking in work area
Storage Conditions: Store only in original, tightly sealed containers in a cool, dry, well-ventilated place, keep away from heat sources, sparks, open flames, and incompatible chemicals
Storage Incompatibilities: Strong oxidizers, acids, and bases
Recommended Packaging: Drum, bottle, or can of material compatible types (such as glass or chemical-resistant plastic)
Engineering Controls: Local exhaust ventilation, eyewash stations, safety showers near work area
Personal Protection: Chemical-resistant gloves (nitrile, neoprene), splash goggles, face shield, impermeable clothing, boots
Respiratory Protection: Approved respirator for organic vapors/fumes if ventilation is inadequate
Occupational Exposure Limits: No workplace exposure standard set for this compound, but exposure should be minimized as with similar organophosphonates
Hygiene Measures: Wash hands, face, and exposed skin after use; do not touch eyes or face before washing

Respiratory Sensitization: May cause irritation to nose, throat, and lungs
Chronic Effects: Prolonged contact may trigger dermatitis, possible liver or kidney impacts with systemic exposure
Carcinogenicity: Not evaluated as a confirmed carcinogen by IARC, NTP, or OSHA
Other Information: No significant data on reproductive toxicity or teratogenic effects; professional judgment suggests caution with repeated exposures
Ecotoxicity: Highly toxic to aquatic organisms, fish LC50 (96h) below 1 mg/L, risk of acute and long-term damage
Persistence and Degradability: Slow in environment, persistent due to low water solubility and bioaccumulation
