Impurities: May contain unreacted intermediates from manufacture in trace amounts
Ingredient Disclosure: Dye content high; other ingredients typically sodium chloride, sodium sulfate, water (in negligible amounts)
Inhalation: Move person to fresh air, reassure, seek help for breathing difficulty, wash out mouth
Skin Contact: Wash immediately with soap and plenty of water, remove contaminated clothing, persistent irritation needs medical advice
Eye Contact: Rinse under running water for several minutes, remove contact lenses, medical attention if symptoms do not improve
Ingestion: Rinse mouth immediately, seek medical advice, do not induce vomiting unless instructed by professional
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Hazardous Combustion Products: Emits oxides of sulfur, nitrogen, and sodium when burned
Special Fire Fighting Procedures: Wear self-contained breathing apparatus and protective clothing, avoid smoke inhalation, use standard firefighting methods for chemical fires
Unusual Fire Hazards: Dust can form explosive mixtures with air but rarely poses risk at normal workplace concentrations
Personal Precautions: Use protective equipment such as gloves, safety goggles, dust mask
Spill Cleanup: Avoid creating dust, sweep up material carefully, place in suitable container for disposal, wash spill area with water
Environmental Precautions: Do not let dye enter drains or waterways, large releases can impact local water color and aquatic life
Safe Handling: Avoid contact with eyes, skin, and clothing, wash hands after handling, do not eat/drink/smoke while handling
Storage: Keep container tightly closed, store in a cool, dry, well-ventilated place, keep away from food or strong oxidizing agents
Incompatible Materials: Strong oxidizers, acids, alkalis
Recommendations: Use only approved containers, label clearly for content and hazard
Occupational Exposure Limit: Not established in most jurisdictions
Engineering Controls: Use local exhaust or general ventilation to control airborne dust
Personal Protection: Wear protective gloves, lab coat or apron, safety glasses or goggles
Respiratory Protection: Dust mask or respirator for high concentrations
Hygiene Measures: Wash hands after use, remove contaminated clothing, avoid breathing powder

Acute Toxicity: Oral LD50 (rat) estimated above 2000 mg/kg
Skin Irritation: Low, rare sensitization
Eye Irritation: Possible redness, stinging
Inhalation: Dust may cause irritation
Long-term Exposure: Animal studies show no significant carcinogenic or mutagenic risk at normal human exposure
Allergenicity: Rare reports of hives or mild allergic reactions in sensitive individuals
Other Effects: No known reproductive or developmental toxicity
Ecotoxicity: Moderately toxic to aquatic organisms in concentrated form, risk to environment low in diluted conditions
Persistence and Degradability: Breaks down slowly in aquatic environments under exposure to sunlight and microorganisms
Bioaccumulation: Does not significantly bioaccumulate in aquatic species
Mobility in Soil: Moves slowly due to large molecular weight and charge, small risk of groundwater contamination
Other Adverse Effects: Highly visible red color can affect appearance of water bodies even at low levels
Waste Disposal Methods: Dispose of by controlled landfill or incineration in compliance with local regulations
Container Disposal: Empty packaging should be rinsed, punctured, disposed of as non-hazardous unless contaminated
Avoid Release: Do not discharge concentrated product to natural waterways
Preferred Disposal: Engage qualified waste contractor for large quantities
