Other Ingredients: No additional hazardous substances present as per current data
Inhalation: Remove to fresh air, seek medical attention if symptoms persist such as coughing, shortness of breath, or throat irritation
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing; seek medical attention for persistent irritation, redness, or rash
Eye Contact: Rinse cautiously with water for at least 15 minutes, holding eyelids open; remove contact lenses if easy to do; consult medical advice if irritation continues
Ingestion: Rinse mouth; never induce vomiting unless directed by medical personnel; seek immediate medical care if large quantities are swallowed or if symptoms such as nausea, vomiting, or abdominal pain appear
Note for Physicians: Treat symptomatically, monitor for possible allergic reactions or chemical-induced injury
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: High-pressure water streams may cause spread of powder
Specific Hazards: Decomposition emits toxic fumes of sulfur oxides, nitrogen oxides, and carbon monoxide
Protective Equipment: Full protective clothing, self-contained breathing apparatus
Special Firefighting Procedures: Move containers from fire area if it is safe; prevent runoff into drains; ventilate area post-fire
Personal Precautions: Evacuate area; avoid dust formation; wear protective equipment including gloves, goggles, suitable mask or respirator
Environmental Precautions: Prevent entry to drains, surface and ground water; notify relevant authorities if significant environmental release occurs
Clean-up Methods: Sweep up spillage without raising dust; collect in sealable containers for disposal; ventilate area and wash spill site after material pickup
Additional Advice: Avoid repeated skin and eye contact; treat contaminated surfaces with water and detergent
Handling: Use with adequate ventilation; minimize contact with skin, eyes, and clothing; do not eat, drink, or smoke while using; wash hands thoroughly after use
Storage: Keep in tightly closed containers in a cool, dry, well-ventilated environment; avoid storage near oxidizing agents or incompatible substances; label containers clearly with hazard information; store away from foodstuffs and animal feed
Packaging Materials: Use containers made of corrosion-resistant material with tight fitting lids
Exposure Limits: No official occupational exposure limits established, but minimize dust exposure
Engineering Controls: Local exhaust ventilation recommended; maintain protective equipment stations nearby
Personal Protective Equipment: Respiratory protection such as an approved dust mask or respirator for airborne dust; chemical-resistant gloves for hand protection; safety goggles or glasses for eye protection; protective clothing covering skin to prevent contact; eye-wash facilities in the vicinity of use
Hygiene Measures: Change contaminated clothing; wash hands after working with product; keep work area clean and free from dust accumulation
Appearance: Red to reddish-brown powder or granules
Odor: Odorless or faint, chemical-like weak odor
Odor Threshold: Not determined
pH (1% Solution): 5.0-7.0
Melting Point: Decomposes before melting (typical for organic dyes)
Boiling Point: Not applicable

Partition Coefficient (n-octanol/water): Not determined
Density: Approximately 1.5 - 2.0 g/cm³
Viscosity: Not applicable
Chemical Stability: Stable under recommended storage and handling conditions
Incompatible Materials: Strong oxidizers, strong acids
Conditions to Avoid: Excessive moisture, dust formation, exposure to heat or open flame
Hazardous Decomposition Products: Sulfur oxides, nitrogen oxides, carbon monoxide, sodium compounds emitted during strong heating or combustion
Hazardous Polymerization: Product does not polymerize in normal use
Acute Toxicity: Harmful if swallowed; may cause gastrointestinal discomfort, nausea, vomiting, and diarrhea
Skin Irritation: May cause redness, mild irritation, possible dermatitis with prolonged contact
Eye Irritation: May cause moderate irritation, redness, watering, stinging
Respiratory Effects: Inhalation of dust can irritate nose, throat, respiratory tract
Chronic Effects: Repeated or prolonged exposure may cause skin sensitization or potentially allergic reactions
Carcinogenicity: Some acid red azo dyes are under scrutiny; available data offers limited evidence of carcinogenic risk
Reproductive Toxicity: No conclusive information from current studies
Mutagenicity: Animal studies indicate some azo dyes can break down into aromatic amines that are mutagenic under certain conditions
Aquatic Toxicity: Toxic to aquatic organisms; can cause harmful long-term effects in aquatic environments by inhibiting natural microbial activity and harming fish or invertebrates
Persistence and Degradability: Poor biodegradability observed; tends to persist in water and soils, breaking down slowly
Bioaccumulative Potential: Evidence for bioaccumulation is limited but persistent substances can build up in aquatic organisms
Mobility in Soil: Soluble nature increases mobility in moist soils, risk of contamination in surface or groundwater
Other Adverse Effects: Coloring of waterways impacts light penetration and ecosystem balance
Waste Treatment Methods: Dispose of contents and container using licensed waste disposal contractors
Disposal of Product: Waste contaminated with dye must never enter waterways; incineration or secure landfill according to local regulations
Container Disposal: Empty containers must be handled as hazardous waste unless thoroughly cleaned
Regulatory Provisions: Abide by all relevant international, national, and regional waste disposal instructions; avoid unapproved discharges into environment
