Most Important Symptoms: Redness, swelling, itching, respiratory discomfort, gastrointestinal upset
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide may be used for fires in surrounding materials
Specific Hazards: Product may decompose under fire conditions to release hazardous gases such as sulfur oxides, nitrogen oxides, hydrogen chloride
Protective Equipment: Firefighters need full protective gear and self-contained breathing apparatus to avoid inhaling toxic fumes
Special Methods: Cool exposed containers with water spray to prevent overheating, prevent runoff from fire control entering waterways
Personal Protection: Avoid dust formation, ventilate area, wear gloves, goggles, lab coat or appropriate PPE
Environmental Protection: Prevent spilled material from entering drains, sewers, or waterways, contain spill with suitable absorbent material
Cleanup Methods: Sweep up carefully, avoiding dust dispersal, transfer to labeled waste container for disposal, wash area with plenty of water
Precautions for Safe Handling: Handle with care, minimize dust generation, avoid inhalation and contact with skin and eyes, use proper PPE
Safe Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated area, away from incompatible substances like strong acids and oxidizers
Storage Class: Store with other inorganic chemicals, segregate from foodstuffs and reactive chemicals
Occupational Exposure Limits: No specific OSHA or ACGIH exposure limits established, use workplace dust limits as guideline
Engineering Controls: Local exhaust ventilation or fume hood recommended for bulk handling

Decomposition Products: Decomposes with heat to release sulfur oxides, nitrogen oxides, hydrogen chloride, sodium oxides
Conditions to Avoid: Excessive heat, moisture, open flames, contamination with incompatible substances
Acute Toxicity: Low oral and dermal toxicity expected based on available data for related sulfonates, may cause irritation to exposed tissues
Skin Corrosion/Irritation: Causes skin irritation with prolonged or repeated exposure
Eye Damage/Irritation: Causes moderate to severe eye irritation
Respiratory Sensitization: Can cause coughing or throat irritation if inhaled as dust
Chronic Effects: No data on long-term health effects, sulfonates rarely cause systemic toxicity unless exposure is prolonged and significant
Carcinogenicity: Not listed as a known carcinogen by IARC, NTP, or OSHA
Mutagenicity: No studies showing mutagenic effects available for this molecule
Reproductive Toxicity: Not known to harm reproductive organs or development at typical exposure levels
Ecological Toxicity: Product can affect aquatic organisms if released in large amounts, detailed aquatic toxicity data limited, structurally similar sulfonates show low to moderate toxicity to algae and daphnia
Persistence and Degradability: Partially biodegradable, may persist in soil or sediment for weeks to months
Bioaccumulation: Not expected to bioaccumulate significantly based on structure and known analogues
Mobility in Soil: High solubility in water increases mobility, may enter water table from spills if not properly contained
Other Adverse Effects: No information on effects on ozone depletion, photochemical ozone creation, or global warming potential
Waste Treatment Methods: Waste material should be collected and sent to approved chemical disposal facility, do not discharge into drains or environment
Container Disposal: Rinse empty containers thoroughly, puncture or crush to prevent reuse, label as hazardous chemical waste
Disposal Guidance: Follow local, regional, and national regulations for hazardous waste, confirm with environmental protection agencies for specific rules
