Personal Precautions: Put on appropriate protective equipment including gloves, eye goggles, laboratory coat, and respiratory protection if excessive dust present
Environmental Precautions: Prevent material or washings from entering drains, sewers, or waterways; potential impact on aquatic life persists
Containment: Scoop up spilled powder with non-sparking tools or wet methods to suppress dust, transfer to labeled waste containers for proper disposal
Clean-up Procedure: Wash area of release with water and detergent, ventilate affected space, restrict access during clean-up, air monitoring may be necessary in enclosed environments
Handling: Work in areas with local exhaust ventilation or chemical hoods, avoid skin or eye contact and inhalation of dust or aerosols, utilize standard laboratory safety procedures for scale
Storage: Store in original tightly closed containers in a cool, dry, well-ventilated place, protected from incompatible substances and direct sunlight; avoid temperature extremes to limit degradation
Incompatibilities: Strong oxidizing agents, strong acids, and bases can break chemical bonds, encourage unwanted reactions
Hygiene Practices: Do not eat or drink in work areas, wash hands after use, keep containers labeled and sealed when not in use
Engineering Controls: Laboratory fume hoods or local exhaust where feasible, HEPA filters on exhaust for powder handling, maintain negative pressure in storage and prep rooms
Personal Protective Equipment: Barrier gloves (such as nitrile), safety goggles or face shields when splash is possible, laboratory coats or coveralls, NIOSH/MSHA-approved respirators for high-dust operations
Exposure Limits: No established occupational exposure limits for this compound; general dust and nuisance particulate limits apply (such as 10 mg/m³ total inhalable dust)
Environmental Controls: Closed systems in industrial production, regular air monitoring, waste capture protocols to prevent environmental discharge
Physical State: Solid powder, typically appears as a deep colored fine particulate
Color: Deep yellow to orange-red, color intensity reflects dye purity
