Eye Contact: Rinse eyes thoroughly with water at least 15 minutes, open eyelids fully, remove contact lenses after a minute, get medical attention if irritation continues
Skin Contact: Wash exposed area with soap and plenty of water, remove contaminated clothing, dispose of used water properly, seek help for continued irritation or rash
Ingestion: Rinse mouth with clean water, avoid inducing vomiting, get medical help immediately, prepare information on product used and amount swallowed
Suitable Extinguishing Media: Use dry chemical, CO2, foam, or water spray; do not use high-pressure water jet
Specific Hazards: Combustion creates toxic fumes including nitrogen oxides, sulfur oxides, and sodium compounds
Protective Equipment for Firefighters: Wear full protective gear and self-contained breathing apparatus, keep upwind of fire source, avoid breathing smoke
Special Procedures: Cool nearby containers with water spray, prevent runoff from reaching water sources, remove unaffected material if safe
Personal Precautions: Wear appropriate gloves, chemically resistant boots, and safety goggles, avoid contact with skin and eyes, do not create dust
Environmental Precautions: Recover product quickly, block off drains and waterways, avoid release to environment as chemical can harm aquatic life
Methods for Clean-up: Scoop up spilled material using non-sparking tools, avoid generating dust, place in sealed container, wash residue with sodium carbonate solution then rinse thoroughly, ventilate area
Safe Handling: Avoid inhaling dust or ingesting, handle inside chemical fume hood or with local exhaust ventilation, wash hands after work, keep food and drink away from workspace
Storage Conditions: Keep container in cool, dry, well-ventilated space, protect from light and moisture, store apart from oxidizers and acids
Specific Design Considerations: Use clearly labeled containers, maintain good housekeeping, store at ambient temperature, secure away from unauthorized personnel, regular inspection for container integrity encouraged
Exposure Limits: No established occupational exposure limits for this compound
Engineering Controls: Use enclosure solutions like glove box or chemical fume hood, ensure good ventilation, consider HEPA filtration for airborne particulates
Personal Protective Equipment: Nitrile or neoprene gloves, lab coat, safety glasses with side shields, dust-resistant respirator if airborne particles, avoid skin exposure
Hygiene Measures: Remove contaminated clothing before leaving work area, dispose of personal protective equipment based on contamination, do not eat, drink, or smoke in storage or handling areas
Appearance: Orange to reddish-brown powder or crystals
Odor: Slight aromatic odor
pH: Typically between 7-8 in 1% aqueous solution
Melting Point: Decomposes above 200°C
Solubility: Freely soluble in water, slightly soluble in alcohol, insoluble in most organic solvents
Boiling Point: Not applicable due to decomposition
Vapor Pressure: Negligible at room temperature
Relative Density: Approximately 1.34 g/cm³
Partition Coefficient: Data unavailable; likely low due to ionic character
Flammability: Non-flammable but may combust if exposed to strong ignition source
Other Properties: Stable color in solution at neutral pH, sensitive to strong acids and oxidizers
Chemical Stability: Stable under recommended storage conditions, breaks down if exposed to strong light or acids
Hazardous Reactions: Reacts with strong oxidizing agents with possible risk of fire
Conditions to Avoid: Extreme temperatures, acids, light, moisture
Incompatible Materials: Strong oxidizers (sodium hypochlorite, peroxides), strong acids (sulfuric or hydrochloric acids)
Decomposition Products: Produces nitrogen oxides, sodium compounds, and sulfur oxides on combustion
Polymerization Risk: No hazardous polymerization expected
Acute Toxicity: Harmful by oral route, lack of significant inhalation toxicity but can irritate respiratory system
Skin Corrosion/Irritation: Can cause irritation, prolonged contact raises risk of allergic reaction
Eye Damage/Irritation: Causes moderate to severe irritation
Respiratory Sensitization: Dust may irritate nose, throat, and lungs
Carcinogenicity: Azo compounds linked to carcinogenic risk in some cases, not classified as proven human carcinogen for this compound
Mutagenicity: Limited data, azo compounds may be mutagenic, handle with caution
Other Effects: Prolonged or repeated exposure to skin may cause dermatitis
Ecotoxicity: Harmful to aquatic life, can persist in water and soil, decomposition can produce toxic byproducts hazardous to plants and fish
Mobility in Soil: Moderately mobile due to water solubility, can leach to groundwater if not properly contained
Persistence and Degradability: Persists under typical environmental conditions, slow breakdown under natural light and biological processes
Bioaccumulative Potential: Low potential due to ionic structure, not expected to accumulate in aquatic organisms
Other Information: Spills should never be flushed to sewer or water systems, local regulations on discharge apply
