Safety & Handling
Hazards
- Toxicity:
- Inhalation/Ingestion: Causes irritation to the respiratory tract and gastrointestinal system; may be carcinogenic (IARC classification: Not classified, but nitroaromatics have potential risks).
- Skin Contact: Irritates skin and may be absorbed, leading to methemoglobinemia (reduced oxygen-carrying capacity of blood).
- Explosion Risk:
- Dust may form explosive mixtures with air; avoid high-temperature or flame exposure.
- Environmental Impact:
- Toxic to aquatic organisms; persists in water and soil.
Safety Measures
- Personal Protection:
- Wear chemical-resistant gloves, goggles, and a respirator (N95 or higher) in dusty environments.
