General Advice: Everyone working with this material should practice good industrial hygiene and safety procedures. If exposure occurs, leave the area and limit contact.
Inhalation: Remove person from exposure, seek fresh air, provide oxygen if breathing is difficult, get medical attention if symptoms persist.
Skin Contact: Immediately wash affected skin with plenty of water and soap, remove contaminated clothing and shoes, consult healthcare provider in case of irritation or rash.
Eye Contact: Promptly flush eyes with lukewarm water, lifting eyelids for at least fifteen minutes, remove contact lenses if present, see medical professional without delay if irritation remains.
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting unless directed by a medical professional, seek immediate medical help if large amounts are consumed or if symptoms arise.
Most Important Symptoms/Effects: May cause irritation of eyes, skin, upper respiratory tract; prolonged repeated contact may result in sensitization.
Suitable Extinguishing Media: Use dry chemical, foam, water spray, or carbon dioxide; avoid using direct water jets on dust that may become airborne.
Hazards from Combustion Products: Toxic gases such as nitrogen oxides, sulfur oxides, chlorine, and carbon monoxide may form on decomposition.
Protective Equipment: Firefighters need full personal protective equipment including self-contained breathing apparatus; evacuate area of non-emergency personnel.
Firefighting Instructions: Control and contain runoff, approach from upwind, keep containers cool with water
Explosion Risk: Fine dust is capable of forming explosive mixtures with air under certain conditions.
Personal Precautions: Move unnecessary personnel away, avoid dust formation, wear gloves, goggles, dust respirator.
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid material reaching drains, surface water, and soil.
Cleanup Procedures: Contain spill with inert absorbent, collect and place in labeled waste container, ventilate area after cleanup, wash spill area thoroughly after removal, avoid sweeping or actions that raise dust.
Methods for Disposal: Dispose of waste according to local and national regulations, never discharge into environment.
Handling: Minimize dust generation and accumulation, do not eat, drink, or smoke during use, wear suitable personal protection, handle in accordance with good industrial hygiene and chemical safety guidelines.
Storage: Store in tightly closed, clearly labeled containers in dry, well-ventilated area away from incompatible substances such as strong oxidizers and acids, protect from light and moisture, protect from heat or open flames.
Incompatibilities: Avoid storing with acids or bases, strong oxidizers, or reducing agents as violent reactions may occur.
Other Precautions: Inspect containers routinely for integrity, keep away from food and drinks, maintain access to eyewash and safety shower stations.
Occupational Exposure Limits: No established exposure limits for this specific compound; use dust limit guidelines (OSHA PEL for nuisance dust: 15 mg/m³ total, 5 mg/m³ respirable fraction).
Engineering Controls: Work in a chemical fume hood or use local exhaust ventilation to keep dust concentrations below relevant limits, avoid recirculating air.
Personal Protection: Wear approved safety glasses or chemical goggles, gloves (nitrile or rubber), lab coat, long sleeves, appropriate dust respirator (NIOSH-approved) for dusty environments.
General Hygiene: Wash hands before breaks and at the end of the shift, remove and wash contaminated clothing before reuse.

Conditions to Avoid: Keep away from heat, flames, open sparks, contact with incompatible materials, avoid prolonged exposure to light
Incompatible Materials: Acids, strong bases, oxidizers
Acute Toxicity: Oral, dermal, and inhalation toxicity data not fully established for this compound, similar azo dyes have low acute toxicity when handled correctly.
Routes of Exposure: Skin contact, eye contact, inhalation
Symptoms: Redness and irritation in eyes, skin can show localized redness or rash, inhalation may prompt coughing or respiratory discomfort
Chronic Effects: Some azo dyes linked to sensitization and allergic reactions, insufficient evidence exists regarding carcinogenicity for this compound, prolonged occupational exposure could cause dermatitis.
Other Information: No information available on mutagenicity, reproductive toxicity, or specific organ toxicity from repeated exposure.
Ecotoxicity: Data specific to this complex azo-compound are limited, but azo dyes often display moderate aquatic toxicity; can bioaccumulate given persistent structure
Persistence and Degradability: Poorly biodegradable; chemically stable dyes remain in aquatic environments for long periods
Bioaccumulative Potential: Potentially persistent in sediments and biological tissues due to high molecular weight
Mobility in Soil: Though water-soluble, binds strongly to soil particles and organic matter
Other Adverse Effects: Effluent containing this dye can decrease photosynthesis in aquatic environments by blocking sunlight
Waste Treatment Methods: Collect waste dye, contaminated packaging, and cleanup materials in sturdy, clearly labeled containers for hazardous waste collection
Disposal of Product: Dispose via incineration in approved facility wherever practical, avoid landfill unless required by regulation
Disposal of Contaminated Packaging: Triple-rinse and offer for recycling if possible, otherwise treat as chemical waste
