Protective Equipment for Firefighters: Full-face self-contained breathing apparatus, chemical-protective clothing recommended
Firefighting Procedures: Use water spray to cool unopened containers; approach fire from upwind to avoid hazardous vapors; prevent runoff from entering drains or watercourses
Personal Precautions: Keep unprotected personnel away; use proper personal protective equipment including gloves and goggles; ventilate area to disperse any fumes
Environmental Precautions: Prevent product from entering drains, surface water, or soil; contain spill with sand or earth
Spill Cleanup Methods: Sweep up and shovel material into suitable container for disposal; avoid generating dust; ventilate contaminated area fully following cleanup; dispose based on local requirements; wash spill site with water after removal
Additional Advice: Report large spills to appropriate authorities as required by regulatory standards
Handling: Use only in well-ventilated areas; avoid contact with skin, eyes, and clothing; do not breathe dust, fumes, or vapors; wash hands and face after handling; keep containers tightly closed
Storage: Store in cool, dry, well-ventilated area; keep container tightly sealed and protected from moisture; store away from strong bases, oxidizers, and foodstuff; recommended storage temperature: 2–8°C
Specific End Use: Reserved for professional users with appropriate protective measures in place
Occupational Exposure Limits: No established regulatory limits for this compound
Engineering Controls: Use fume hood or adequate ventilation system to control airborne concentrations
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene recommended), lab coat, protective eyewear (goggles or face shield), respiratory protection when dust is present
Hygiene Measures: Remove contaminated clothing and wash all exposed skin after handling; avoid eating, drinking, or smoking during use; maintain eyewash station and safety shower in working area

Skin Corrosion/Irritation: Causes severe skin burns (based on molecular structure and classification)
Serious Eye Damage/Irritation: Causes serious eye damage
Respiratory or Skin Sensitization: May cause respiratory irritation by inhalation, especially in powder form
Chronic Effects: No data supporting carcinogenicity, mutagenicity, or reproductive toxicity; repeated or prolonged exposure can result in dermatitis or mucous membrane irritation
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Symptoms: Burning sensation, coughing, abdominal pain, lachrymation, redness, blistering, ulceration
Toxicity: Acute aquatic toxicity data not fully established; potential to harm aquatic organisms based on sulfonic acid structure
Persistence and Degradability: Compound contains organic sulfonic acid group, which may not readily biodegrade; potential for environmental persistence
Bioaccumulative Potential: Not expected to bioaccumulate based on low log Pow; data insufficient for complete risk evaluation
Mobility in Soil: Likely to be highly mobile when dissolved due to water solubility
Other Adverse Effects: Avoid release to environment; may lower local water pH, harming aquatic life
Waste Disposal: Handle as hazardous chemical waste; consult local, regional, and national regulations for proper disposal methods
Contaminated Packaging: Empty containers retain residue, dispose using licensed chemical waste contractor
Additional Guidance: Do not discharge to sewers or waterways; neutralize with base before disposal if authorized; document all waste shipments
