Inhalation: Move person to fresh air, keep comfortable and observe for breathing difficulty, seek medical attention if symptoms develop
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, call doctor if skin irritation appears
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing and get medical support if eye irritation persists
Ingestion: Do not give anything by mouth to an unconscious person, rinse mouth with water, seek immediate medical attention
Most Important Symptoms: Dizziness, headache, burning sensation on skin or eyes
Medical Attention and Special Treatment: Treat symptomatically, monitor respiratory status if exposed via inhalation
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray (do not use direct water stream as it may spread fire)
Hazards from Combustion: Emits aldehydes, acids, carbon oxides, and irritating fumes when burned
Firefighting Instructions: Wear self-contained breathing apparatus, full protective gear, use water spray to cool exposed containers
Special Protective Equipment: Firefighters require chemical-resistant clothing and positive pressure breathing apparatus
Explosion Sensitivity: Vapor may form explosive mixture with air above flash point (approx. 55°C)
Personal Precautions: Evacuate personnel from area, ventilate area, eliminate all ignition sources, avoid inhalation of vapors
Environmental Precautions: Prevent material from entering drains, surface or ground waters
Spill Containment: Absorb with inert material such as sand or vermiculite, collect for disposal in sealed container
Cleanup Procedures: Use non-sparking tools and equipment, wash contaminated area with soap and water after removal
Safe Handling: Use only in well-ventilated areas, keep away from open flames, sparks, and hot surfaces, do not smoke, avoid contact with skin and eyes, wear compatible gloves and goggles
Storage Conditions: Store in tightly sealed original container, away from heat, direct sunlight, oxidizing agents, acids, and strong bases
Storage Temperature: Maintain in cool, dry area between 5°C and 25°C
Shelf Life: Product typically maintains stability for up to 24 months under recommended storage conditions
Incompatible Materials: Strong acids, bases, oxidizing agents
Engineering Controls: Use process enclosures, local exhaust ventilation to control airborne levels below recommended exposure limits
Occupational Exposure Limits: No official workplace exposure limits established; handle as an irritant
Personal Protective Equipment: Chemical resistant gloves (nitrile, neoprene), safety goggles or face shield, flame-retardant lab coat, use respiratory protection if ventilation is inadequate
Hygiene Measures: Wash hands and face before eating, drinking or smoking, remove contaminated clothing after work

Respiratory Effects: Inhalation of high vapor concentrations can cause dizziness, drowsiness, respiratory irritation
Sensitization: No data on sensitization or allergy response
Chronic/Long Term Effects: No long-term studies on carcinogenicity, mutagenicity, reproductive toxicity
Additional Information: Exposure symptoms tend to improve with removal from area and fresh air
Ecotoxicity: Harmful to aquatic life in high concentrations; aquatic invertebrates and fish may be affected
Mobility: Spill can travel through soil and contaminate groundwater
Persistence and Degradability: Degrades slowly in natural environment; not readily biodegradable
Bioaccumulation: Moderate potential for bioaccumulation
Other Adverse Effects: Avoid uncontrolled release to the environment to prevent ecological disruption, especially in watercourses
