Name: Sulfuryl Fluoride
Chemical Formula: SO2F2
Common Uses: Fumigant for structural pest control, food processing plants, and grain storage
Physical Appearance: Colorless, odorless gas under normal temperature and pressure
Detection Method: Specialized gas detectors since the gas is odorless and not immediately irritating
Acute Hazards: Inhalation harms the respiratory system and central nervous system; very high concentrations cause death
Chronic Hazards: Repeat or prolonged exposure brings risk of long-term lung or neural issues
Symptoms of Exposure: Coughing, shortness of breath, nausea, dizziness, weakness, tremor, in severe cases, convulsions
Environmental Risks: Not flammable, but heavier than air; collects in low-lying areas, endangering workers who do not use monitors
OSHA Class: Poisonous gas, subject to regulations targeting acute and chronic exposure
Main Ingredient: Sulfuryl Fluoride (pure)
Concentration: Typically delivered and used as 99.5% or greater purity, with trace impurities depending on production
Inhalation: Remove the person from exposure, keep them at rest, supply oxygen if breathing turns difficult, begin CPR if breathing stops
Skin Contact: Rapidly remove contaminated clothing; wash exposed skin with soap and water if in high-concentration
Eye Contact: Flush eyes with plenty of water for at least 15 minutes; seek immediate medical help
Ingestion: Not a realistic route given the gas form
Medical Advice: Physicians watch for delayed pulmonary edema and neurological symptoms
Flammability: Not flammable
Explosion Risk: No risk of explosion from the gas alone;
Decomposition Products: Exposed to fire or high heat, forms toxic gases such as sulfur dioxide and hydrogen fluoride
Protective Actions: Firefighters wear self-contained breathing apparatus; do not use direct water streams on leaking tanks
Suitable Extinguishing Methods: Use diluting water spray, dry chemicals for fires in the vicinity
Evacuation: Clear the area of unprotected personnel; move to fresh air
Spill Response: Ventilate area, isolate and stop leak if safe, use gas monitors to confirm all gas has dissipated
Personal Protection: Use supplied-air respirators, keep skin covered
Environmental Release: Prevent the gas from accumulating around confined spaces heaters, sumps, or basements
Storage: Keep containers tightly closed in a well-ventilated, secure place, away from heat and direct sunlight
Handling Precautions: Only trained workers should handle transfer; all spaces should be monitored with gas detection equipment
Safe Practice: Do not allow the gas to contact water; compatible with standard fumigation hardware and systems; avoid overfilling application enclosures
Exposure Limit: OSHA sets permissible exposure limits, enforced by continuous gas detection in workplaces
Engineering Controls: Use local exhaust ventilation and alarm-equipped monitors
Personal Protection: Full-face supplied-air respirators, chemical-resistant gloves, protective suits for entry into contaminated areas
Hygiene Measures: Workers should wash thoroughly after contact, keep contaminated gear away from clean areas, and decontaminate after use in confined spaces
State: Gas at room temperature
Odor: Odorless
Boiling Point: -55 degrees Celsius
Solubility: Poorly soluble in water, better in organic solvents
Vapor Density: Heavier than air
Pressure: High-pressure when stored in cylinders
Stability: Stable under recommended storage conditions
Materials to Avoid: Reacts with water producing corrosive fumes of hydrofluoric and sulfuric acids
Decomposition: High heat and flames drive decomposition, yielding toxic gases
Polymerization: Does not polymerize
Acute Toxicity: Inhalation damages lungs and neurons; human lethal dose is very low
Delayed Effects: Neurological symptoms often present hours after exposure
Target Organs: Respiratory system, central nervous system
Carcinogenicity: No evidence of cancer in humans
Other Effects: Potential for permanent respiratory or neurological problems if not treated promptly
Persistence: Breaks down slowly, remains in the atmosphere several decades
Bioaccumulation: Does not bioaccumulate in organisms
Toxicity to Wildlife: Harmful to insects and certain invertebrates; airborne releases can drift and impact unintended areas
Environmental Fate: Not destroyed by water; sunlight and upper atmosphere drive chemical breakdown
Waste Handling: Unused gas returned to supplier; not released to air except in controlled, permitted fumigation sites
Container Disposal: Cylinders sent for recycling or reconditioning after being emptied and vented safely
Regulatory Requirements: Disposal methods subject to hazardous waste law; spills or fugitives require notification of authorities
UN Number: Designated as a toxic gas for rail, road, air, or sea transport
Packing: Shipped in heavy, clearly labeled cylinders
Special Handling: Trained personnel required for all transfer, shipping, and receiving steps among handlers
Accident Precautions: Shipping documents must travel with product and include specialized hazard warnings
Workplace Rule: Occupational health agencies in multiple countries set exposure limits and reporting obligations
Pesticide Law: Labels and uses regulated as a fumigant; violations draw fines and operational restrictions
Environmental Controls: Regulated by air pollution and chemical safety agencies for bulk and use; use of gas justified only where other pesticides fail or cannot be used
Worker Rights: Employees trained according to strict hazard communication rules with access to risk information
