Recommendations for Medical Providers: Treat symptomatically, monitor respiratory, renal and hepatic function
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water jet may spread fire
Specific Hazards: Vapors may form explosive mixtures with air, emits toxic fumes of nitrogen oxides and carbon oxides when heated
Protective Equipment for Firefighters: Self-contained breathing apparatus, full chemical-resistant clothing
Special Precautions: Cool containers with water spray to prevent rupture, avoid run-off entering drains
Personal Precautions: Avoid inhalation and contact with skin and eyes—ensure adequate ventilation, evacuate area if necessary
Protective Equipment: Wear gloves, goggles, chemical-resistant apron, and respirator if vapor concentrations are high
Environmental Precautions: Prevent liquid from entering soil, drains, or watercourses
Methods for Containment: Stop leak if safe, absorb with inert materials such as sand or soil
Clean-up Procedures: Collect in suitable container for disposal, flush area with water if safe, dispose through licensed waste handler, ventilate area well
Handling: Work in a fume hood or well-ventilated area, avoid sources of ignition, use spark-proof tools, prevent contact with eyes, skin, and clothing, wash thoroughly after handling
Storage: Store in tightly closed original container, keep away from open flames, heat, and incompatible materials such as acids and oxidizers, store in cool, dry, well-ventilated place, use proper grounding and bonding if transferring
Incompatibilities: Strong acids, oxidizing agents, halogens, some plastics
Exposure Limits: No established OSHA or ACGIH limits; minimize exposure as much as possible
Engineering Controls: Use local exhaust ventilation, safety shower, and eye-wash stations near work area
Respiratory Protection: Use NIOSH-approved respirator if needed
Hand Protection: Impermeable gloves such as nitrile rubber
Eye Protection: Chemical safety goggles or face shield
Skin Protection: Lab coats, full protective clothing where splashing is likely
Hygiene Measures: Avoid eating, drinking, smoking, or applying cosmetics while working—wash hands before breaks and after handling

Materials to Avoid: Strong oxidizers, acids, acid chlorides, acid anhydrides, halogens
Hazardous Decomposition Products: Nitrogen oxides, carbon oxides, ammonia
Polymerization: Does not occur under recommended conditions, can form dangerous gases if involved in a fire
Acute Toxicity: Oral (rat) LD50 ≈ 450 mg/kg, Dermal LD50 not established, Inhalation toxicity likely at high vapor concentrations
Skin Corrosion/Irritation: Causes moderate to severe irritation
Eye Damage/Irritation: Causes severe irritation or burns
Respiratory/Skin Sensitization: Prolonged exposure may cause sensitization in susceptible individuals
Chronic Effects: No definitive evidence of chronic toxicity, but continuous exposure may harm liver or kidneys
Carcinogenicity: Not classified by IARC, NTP, or OSHA
Mutagenicity: No data available
Reproductive Toxicity: No animal data to indicate risk, avoid unnecessary exposure
Target Organs: Skin, eyes, respiratory tract, possibly liver and kidneys upon prolonged exposure
Ecotoxicity: Harmful to aquatic life with acute effects; fish LC50 (96h): 100–200 mg/L
Persistence and Degradability: Expected to biodegrade in environment, rate varies based on conditions
