Inhalation: Remove individual to fresh air, provide oxygen or artificial respiration if breathing is difficult, seek medical attention if symptoms develop
Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water, seek medical attention for persistent irritation or sensitization
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, hold eyelids open, seek prompt medical attention
Ingestion: Rinse mouth, do not induce vomiting, consult a physician immediately
Acute Symptoms: Redness, swelling, blistering, burning sensation on skin or eyes, persistent coughing after inhalation
Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam, water spray (avoid direct water jet which might spread chemical)
Special Hazards: Vapors can form explosive mixtures with air during fire conditions; decomposition generates toxic gases: carbon monoxide, carbon dioxide, and irritating aldehydes
Protective Equipment: Full bunker gear with self-contained breathing apparatus, chemical-resistant gloves, safety goggles
Firefighting Instructions: Cool surroundings with water spray to prevent fire spread, evacuate unnecessary personnel, prevent water runoff from entering drains
Personal Precautions: Wear proper personal protective equipment like gloves and splash goggles; restrict access and evacuate personnel from immediate area
Spill Cleanup Procedures: Absorb residues with inert material such as sand or earth, collect in closed containers for disposal, ventilate affected area
Environmental Precautions: Prevent entry into sewers, waterways, and soil by using dikes or absorbents
Disposal: Dispose in line with national and local chemical waste guidelines; never dump into normal drains or garbage systems
Handling: Use only with adequate ventilation, avoid inhalation or skin contact, implement closed handling systems for bulk transfers
Storage: Keep containers tightly closed and properly labeled, store in cool, well-ventilated area away from sources of ignition, moisture, and incompatible substances such as acids or bases
Special Notes: Avoid pressurizing, cutting, welding, or heating containers even when empty, to prevent explosive decomposition
Hygiene Practices: Wash hands thoroughly after exposure, remove contaminated clothing and wash before reuse, maintain strict housekeeping standards in work areas
Occupational Exposure Limits: No established ACGIH or OSHA limits; always control workplace concentrations as low as possible
Engineering Controls: Local exhaust ventilation, fume hoods, process enclosures as necessary
Respiratory Protection: Certified respirators with organic vapor cartridges for high concentrations or inadequate ventilation
Skin Protection: Impermeable gloves (nitrile, butyl rubber), lab coats or chemical-resistant aprons
Eye Protection: Tight-fitting goggles, face shield for splash risk
Other Protective Equipment: Eye wash stations, emergency safety showers within immediate reach, chemical-resistant footwear

Viscosity: 7-12 mPa·s
Chemical Stability: Stable at ambient temperature away from direct sunlight and incompatible substances
Reactivity: Strongly reactive toward acids, bases, and amines, can polymerize exothermically
Conditions to Avoid: Exposure to heat, sparks, and open flame, contact with moisture, acids, or alkalis
Incompatible Materials: Strong acids, strong oxidizers, strong bases, amines, reducing agents
Hazardous Decomposition Products: Oxides of carbon, formaldehyde, acrid fumes on thermal decomposition or fire conditions
Hazardous Polymerization: Can occur under improper storage or contamination
Likely Routes of Exposure: Skin and eye contact, inhalation of vapors or aerosols
Acute Toxicity: LD50 (oral, rat): >5000 mg/kg; skin irritation in rabbits: moderate to severe
Chronic Effects: Sensitization possible on repeated exposure, dermatitis from prolonged contact, no reliable evidence of carcinogenicity, teratogenicity, or mutagenicity reported
Symptoms of Overexposure: Red, itchy, or blistered skin; intense eye pain and watering; headaches, dizziness, respiratory distress upon inhalation
Medical Conditions Aggravated by Exposure: Skin allergies, eczema, asthma, pre-existing respiratory disorders
Epidemiological Data: Rare cases of occupational sensitization in production facilities have been described in industrial hygiene studies
Ecotoxicity: Documented low to moderate toxicity to aquatic organisms (EC50 > 100 mg/L for Daphnia magna, LC50 > 100 mg/L for freshwater fish)
Persistence and Degradability: Readily biodegradable under aerobic conditions according to OECD guidelines; hydrolyzes in moist environments over time
Bioaccumulation: Low potential (log Kow <2)
Mobility in Soil: Moderate due to partial water solubility; potential to spread through groundwater under spill conditions
Other Hazards: Spilling large quantities near surface water may upset aquatic environments or harm sensitive invertebrates
Waste Treatment Methods: Incinerate in approved chemical incinerators under controlled conditions, neutralize residues as required
Container Handling: Rinse empty containers thoroughly before recycling or disposal, triple-rinse and puncture or crush as local law prescribes
Disposal Regulations: Follow EPA, regional, and national hazardous waste notification and handling protocols
Special Precautions: Never dump directly into public sewers or common landfill, even trace residues may cause industrial waste issues; coordinate with authorized waste handlers for removal
