After Ingestion: Rinse mouth, give small amount of water if victim is conscious, do not induce vomiting, contact physician immediately
Most Important Symptoms: Irritated eyes, skin redness, mild headache, sore throat with high exposures
Suitable Extinguishing Media: Carbon dioxide, dry powder, foam, water spray used in moderate amounts
Unsuitable Media: Do not use strong water jets, which could disperse product
Special Hazards: Releases toxic fumes under fire conditions, such as sulfur oxides and carbon monoxide
Firefighter Protection: Use full protective gear and a self-contained breathing apparatus, avoid inhaling combustion products, cool exposed containers with water spray
Specific Methods: Move undamaged containers from fire area if it can be done without risk
Personal Precautions: Wear protective gloves, closed shoes, chemical splash goggles, ventilate area
Spill Response: Absorb and collect with inert material (sand, earth), place in closed containers for disposal, wash spill site after pick-up
Environmental Precautions: Prevent from entering drains, surface and groundwater, inform environment authorities if contamination is likely
Methods for Cleaning Up: Shovel up bulk, use absorbent pads for residuals, dispose in accordance with local regulations, ventilate area
Safe Handling: Handle with care in a chemical fume hood, avoid splashes and accidental spills, wash hands and face after work
Protective Measures: Do not eat, drink, or smoke while using, keep away from ignition sources, avoid inhaling vapors
Storage Conditions: Keep in tightly closed original containers, store cool and dry, away from heat and open flames, segregate from acids and oxidizers, label containers clearly
Incompatible Materials: Store separately from strong acids, alkalis, oxidizing agents; wash spills promptly to prevent container corrosion or vapor release
Engineering Controls: Chemical fume hood or local exhaust ventilation, prevent vapor build-up
Respiratory Protection: Use approved mask or respirator if exposure limits are exceeded, especially for bigger spills or in poorly ventilated areas
Skin Protection: Nitrile or neoprene gloves, long-sleeved clothing, laboratory coat
Eye Protection: Chemical safety goggles with side shields
Workplace Limits: No established OSHA or ACGIH exposure limits, but minimize exposure through good hygiene and engineering measures
Other Protective Measures: Remove contaminated clothing promptly, provide eyewash stations and safety showers where work involves handling quantities
Appearance: Colorless to pale yellow liquid
Odor: Mild, sweet, sometimes described as slightly sulfurous
Boiling Point: Around 223–225°C (433–437°F)
Melting Point: -13°C (8.6°F)
Solubility: Moderately soluble in water, good solubility in organic solvents (alcohol, ether, chloroform)
Flash Point: 104°C (219°F), closed cup
Vapor Pressure: Very low at room temperature
Auto-Ignition Temperature: Information may not be widely available; general caution with heat sources
Density: About 1.14 g/cm3 at 20°C
pH: Not applicable as a pure liquid
Viscosity: Low to moderate, pours easily but not as thin as water
Chemical Stability: Stable under normal conditions, becomes less stable with heating or long-term exposure to air
Reactivity: Reacts with strong oxidizers releasing heat and possibly hazardous gases
Incompatible Materials: Concentrated acids, strong bases, strong oxidizers, peri acids
Hazardous Decomposition: Produces sulfur oxides, carbon monoxide, carbon dioxide during decomposition or fire
Polymerization Hazard: No hazardous polymerization reported, but avoid mixing with reactive organics
Other Notes: Protect from direct sunlight and moisture to extend shelf life
Routes of Exposure: Absorbed through skin, eyes, by inhalation of vapors, or accidental swallowing
Acute Effects: Skin irritation, moderate eye irritation, may cause mild headache, nausea if inhaled or ingested
Chronic Effects: Not much reliable data on long-term health impacts, but repeat over-exposures may dry skin or irritate airways
LD50 (oral, rat): Estimated above 2000 mg/kg
Mutagenicity/Carcinogenicity: No concrete evidence in animal studies for cancer or mutagenic hazards, use routine precautions to avoid unnecessary contact
Other Notes: Limited data published, handle as chemical of uncertain chronic risk
Aquatic Toxicity: Harmful to aquatic life, especially with prolonged or repeated release
Persistence and Degradability: Slowly biodegradable in natural waters, risk of persistence if released in large quantities
Bioaccumulative Potential: Expected to have low to moderate bioaccumulation factor, caution if handling spills outdoors
Mobility in Soil: May migrate through soil with water, could contaminate groundwater if large quantities spill
Other Adverse Effects: Dispose as hazardous material, minimize uncontrolled release to the environment
Waste Treatment Methods: Collect and incinerate in licensed hazardous waste facility, avoid pouring down drain or natural watercourse
Container Handling: Rinse and neutralize empty containers, send for approved chemical recycling or landfill under hazardous material regulations
Relevant Local Regulations: Observe local, regional, and national laws on chemical waste, label all waste clearly
Other Notes: Never burn in open air, do not mix with household or municipal trash
