Specific Hazards: Emits toxic fumes of nitrogen oxides and hydrogen chloride during combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and chemical-resistant protective clothing
Special Procedures: Cool exposed containers with water spray to reduce pressure build-up; avoid runoff into drains
Explosion Data: No specific explosion risk identified under normal conditions
Personal Precautions: Use chemical-resistant gloves, safety goggles, protective clothing; keep unprotected persons away from area
Environmental Precautions: Prevent material from entering soil, waterways, or drainage systems
Containment: Absorb with sand, earth, or appropriate spill absorbent; sweep up to avoid dust generation
Cleanup: Scoop residue into suitable sealed containers for disposal; ventilate area and wash residue from spill site
Emergency Procedures: Isolate area, contact local authorities as appropriate for hazardous chemical cleanup
Handling: Use only in well-ventilated areas; avoid contact with skin, eyes, or clothing; prevent formation of dust or aerosols; keep containers tightly closed
Hygiene Measures: Wash hands and face before breaks and at end of workday; do not eat, drink, or smoke during use
Storage Conditions: Store in a cool, dry, well-ventilated location; keep away from incompatible substances like strong oxidizers or acids
Packaging: Use corrosion-resistant, sealed containers; label containers properly with chemical identity and hazard information
Incompatibilities: Avoid storage near oxidizers, acids, and strong reducing agents
Occupational Exposure Limits: Not established for this compound; minimize exposure as a precaution
Engineering Controls: Local exhaust ventilation, use of closed handling systems, splash guards
Personal Protective Equipment: Chemical safety goggles, gloves made of nitrile or neoprene, laboratory coat or apron; respiratory protection if ventilation insufficient or dust is expected
Environmental Exposure Controls: Prevent material from escaping into sewer or open water; monitor effluents where feasible
Monitoring Requirements: Periodic workplace assessments for airborne contaminants and surface residues, especially in handling or packaging areas
Appearance: White to off-white crystal or powder
Odor: Mild to no characteristic odor
Melting Point: 255–258 °C
Boiling Point: Decomposes before boiling
pH: Neutral to slightly basic in aqueous solution

Incompatible Materials: Strong oxidizers, acids, strong bases
Acute Toxicity: Not fully characterized; estimated LD50 (oral, rat) > 2000 mg/kg based on similar compounds
Skin Corrosion/Irritation: Causes irritation with contact; repeated exposure increases severity
Serious Eye Damage/Irritation: Irritating to eyes; may result in pain, redness, and watering
Respiratory Sensitization: May cause short-term respiratory discomfort if inhaled as dust
Other Effects: Long-term exposure not adequately studied; may aggravate eczema or other skin disorders
Carcinogenicity/Mutagenicity/Reproductive Toxicity: No reliable evidence to suggest risk at low doses in occupational settings
Aquatic Toxicity: Expected to be toxic to aquatic organisms at elevated concentrations
Persistence and Degradability: Not readily biodegradable; may persist in environment if released
Bioaccumulative Potential: Low potential for bioaccumulation expected based on structure
Mobility in Soil: Highly water soluble, moderate mobility possible; risk of groundwater contamination if released in bulk
Other Adverse Effects: Avoid release to environment; always use proper containment during any operation
Waste Disposal: Collect residues and waste in closed, clearly labeled containers; refer to local, state, and federal regulations for hazardous chemical disposal; incineration or chemical destruction preferred where possible
