Environmental Precautions: Avoid discharge into drains, surface water, or soil; notify proper authorities if accidental release threatens environment
Handling: Use only in well-ventilated areas; avoid dust formation and contact with eyes, skin, clothing; apply good industrial hygiene practices; keep container tightly sealed when not in use
Storage Conditions: Store in a cool, dry, well-ventilated place; keep containers closed and protected from sunlight, heat and moisture; segregate from incompatible substances such as strong oxidizers and acids
Incompatible Materials: Strong oxidizing agents, acids, reducing agents, organic solvents
Control Parameters: No established occupational exposure limits; minimize exposure using engineering controls
Engineering Controls: Use local exhaust ventilation; keep workplace clean to avoid dust accumulation
Personal Protective Equipment (PPE): Chemical splash goggles or face shield; impervious gloves (nitrile or neoprene); laboratory coat or protective clothing; NIOSH-approved respirator when dust or fumes likely
Hygiene Measures: Wash hands thoroughly after handling; do not eat, drink, or smoke while handling material
Environmental Exposure Controls: Prevent spills or runoff into storm drains and waterways

Chemical Stability: Material is stable under recommended handling and storage conditions
Reactivity: Low chemical reactivity in absence of incompatible chemicals
Hazardous Reactions: Contact with strong oxidizers or acids may lead to decomposition and release of hazardous gases
Conditions to Avoid: Excessive heat, direct sunlight, moisture, incompatible substances
Hazardous Decomposition Products: Nitrogen oxides, sulfur oxides, hydrogen chloride, other toxins in fire or high heat
Acute Toxicity: Oral LD50, dermal and inhalation toxicity studies lacking in public records, handle as potentially harmful
Skin Irritation: Causes skin irritation
Eye Irritation: Causes significant eye discomfort and possible corneal injury
Respiratory Sensitization: Inhalation of dust may trigger irritation, coughing, or allergic response in predisposed individuals
Chronic Effects: Repeated/prolonged exposure may lead to dermatitis or respiratory difficulties
Mutagenicity, Carcinogenicity, Reproductive Toxicity: No concrete studies available, prudence required during use
Other Data: Seek medical evaluation for persistent symptoms
Ecotoxicity: Expected to be harmful to aquatic organisms, even at low concentrations; colorant effect may reduce aquatic photosynthesis
Persistence and Degradability: Tends to persist in environment due to stability and resistance to biodegradation
Bioaccumulative Potential: No evidence of significant bioaccumulation, though long-term studies lacking
Mobility in Soil: Moderate to high mobility due to water solubility, could leach into groundwater
Other Adverse Effects: Changes to ecosystem color profile, impact on algae and lower food chain organisms
