Inhalation: Move affected person outdoors, allow fresh air and rest, seek medical advice for breathing difficulty
Skin Contact: Rinse cautiously with plenty of water for at least 15 minutes, remove contaminated clothing, wash skin thoroughly with mild soap, seek medical attention if irritation persists
Eye Contact: Immediately flush eyes with water for at least 15 minutes, lifting upper and lower eyelids, seek medical attention for redness, pain, or lasting discomfort
Ingestion: Rinse mouth without inducing vomiting, give water if person is conscious, seek immediate medical attention, provide product label to medical staff
Symptoms to Watch For: Redness, itching, burning sensation, cough, nausea, headache
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray
Unsuitable Extinguishing Media: Direct water stream (may spread material or cause contamination)
Specific Hazards: Material may emit sulfur oxides, nitrogen oxides, carbon monoxide and carbon dioxide under combustion
Special Protective Equipment: Firefighters need self-contained breathing apparatus, full protective gear
Firefighting Instructions: Isolate area, prevent runoff to water sources and drains, cool containers exposed to flames, avoid inhaling smoke, do not allow reentry until safe
Personal Precautions: Evacuate unnecessary personnel, ventilate area, wear protective gloves, goggles and mask to avoid dust inhalation or skin contact
Environmental Precautions: Prevent entry into waterways, sewage or soil, inform responsible authorities of large spills
Cleanup Methods: Absorb spill with inert dry material, collect residue in suitable sealable containers, avoid creating dust, dispose of in accordance with local regulations, clean contaminated area with soap and water
Handling: Use in a well-ventilated area, minimize dust generation, avoid eating or drinking in area, wash thoroughly after handling, keep containers tightly sealed when not in use
Storage: Store in a cool, dry, well-ventilated place away from direct sunlight and incompatible substances (strong oxidizers), keep container tightly closed, avoid storing near food and beverage
Engineering Controls: Use local exhaust ventilation, safety shower, eye wash station
Respiratory Protection: Wear approved particulate respirator in dusty conditions or when ventilation is inadequate
Eye Protection: Use chemical safety goggles with side protection
Skin Protection: Wear chemical-resistant gloves (nitrile, neoprene), long-sleeved protective clothing
Hygiene Measures: Wash hands and exposed skin before breaks, after handling, and at the end of work shift

Chronic Effects: Prolonged contact may cause dermatitis, rare respiratory symptoms with frequent dust inhalation
Carcinogenicity: No data indicating carcinogenic risk
Mutagenicity: No studies available
Reproductive Toxicity: No evidence from closely related compounds
Ecotoxicity: Material may affect aquatic organisms due to sulfate and aromatic content, emissions should be minimized
Persistence and Degradability: Product likely to be slowly biodegradable in soil and water, aromatic ring structure persists
Bioaccumulation Potential: Expected to be low due to moderate water solubility, high molecular weight
Mobility in Soil: Compound moderately mobile due to sulfonic acid group
Other Adverse Effects: No chlorinated organics, metallic impurities rare, minimize release to surface waters
Waste Disposal Methods: Dispose of via licensed chemical waste contractor, observe all applicable local and national regulations for laboratory chemical disposal
Container Disposal: Empty residue in containers should be triple rinsed, label removed or defaced, used containers managed as chemical waste
