Inhalation: Move person to fresh air; administer oxygen if breathing is difficult; seek medical attention if symptoms occur; avoid direct exposure during rescue
Skin Contact: Remove contaminated clothing immediately; flush skin with running water for at least 15 minutes; wash thoroughly with mild soap; seek medical attention for persistent irritation or burns
Eye Contact: Rinse cautiously with water for 15 minutes, lifting eyelids occasionally; seek immediate medical care; remove contact lenses if present and easy to do
Ingestion: Rinse mouth; do not induce vomiting; offer small amounts of water; never give anything by mouth to an unconscious person; seek immediate medical advice
Important Note: Symptomatic treatment; support respirations if respiratory distress develops
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam
Unsuitable Media: Water jet
Hazards from Combustion: May emit toxic gases including sulfur oxides and carbon oxides
Protective Equipment: Self-contained breathing apparatus (SCBA); full firefighting turnout gear
Firefighting Instructions: Evacuate area; cool containers with water spray if exposed to heat; contain runoff to prevent water contamination
Flash Point: Not determined; generally considered combustible
Explosion Data: No sensitivity information available; treat as standard for organic sulfates
Personal Precautions: Evacuate unnecessary personnel; wear chemical-resistant clothing, nitrile gloves, and safety goggles
Environmental Precautions: Prevent entry into waterways, drains, or sewers; contain and collect spillage
Methods for Containment: Dike with inert absorbent such as sand or vermiculite
Clean-Up Methods: Use non-sparking tools to gather spilled material; collect in sealable containers for disposal
Decontamination: Wash area thoroughly with water and detergent after clean-up
Handling: Wear appropriate PPE; use only in well-ventilated areas or fume hoods; avoid contact with eyes, skin, and clothing; prevent aerosol or vapor formation
Storage: Keep container tightly closed, in a cool, dry, and well-ventilated place; separate from incompatible materials such as strong bases, oxidizers, and acids; maintain at temperatures below 25°C; use corrosion-resistant containers
Incompatibilities: Strong reducing agents, alkalis, oxidizing substances
Technical Measures: Store away from food and drink; keep away from heat and direct sunlight
Occupational Exposure Limits: No OSHA PEL or ACGIH TLV established; minimize exposure as general safety practice
Engineering Controls: Use chemical fume hood; local exhaust as needed
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat, closed-toe shoes

Decomposition Temperature: Not determined
Viscosity: Not established
Chemical Stability: Stable under recommended storage conditions
Thermal Decomposition: Produces sulfur oxides, carbon oxides, ethylene gas
Hazardous Reactions: Reacts with strong bases to liberate heat; may react with oxidizers violently; moisture can cause hydrolysis
Conditions to Avoid: Heat, open flame, sparks, moisture, strong oxidizing conditions
Materials to Avoid: Reducing agents, oxidizers, alkalis, acids
Hazardous Decomposition Products: Sulfur dioxide, carbon monoxide, carbon dioxide
Acute Toxicity (Oral): Data limited; ingestion likely to cause severe irritation and burns
Acute Toxicity (Inhalation): Expected to cause respiratory tract irritation, potential lung injury at high concentrations
Acute Toxicity (Dermal): Severe skin irritation and possible burns
Skin Corrosion/Irritation: Corrosive to skin; immediate effects on exposure
Serious Eye Damage/Irritation: Corrosive to eyes, may cause permanent eye damage including blindness
Respiratory Sensitization: Not expected
Skin Sensitization: Not expected
Carcinogenicity: No data available; not listed by IARC, NTP, OSHA
Reproductive Toxicity: No studies available
LD50: Not well defined; handle as highly hazardous
Repeated Dose Effects: No chronic toxicity data; long-term exposure should be avoided
Ecotoxicity: May cause adverse environmental effects in aquatic environments; harmful to aquatic organisms based on structural similarity to related compounds
Persistence and Degradability: Decomposes slowly in water to yield ethylene glycol and sulfur dioxide
Bioaccumulation: Potentially low bioaccumulation due to high water solubility
Mobility in Soil: High due to water solubility; can reach groundwater if released
Other Adverse Effects: Insufficient data to assess ozone depletion or endocrine disruption potential
