Protective Equipment: Firefighters should use self-contained breathing apparatus and wear protective clothing
Special Precautions: Evacuate area, avoid inhaling combustion products, cool fire-exposed containers with spray
Personal Precautions: Wear chemical-resistant gloves, protective eyewear, and clothing, ventilate area
Environmental Precautions: Prevent entry into drains, soil, and water sources
Methods for Clean-Up: Contain spill with inert absorbent, collect into labeled containers, seal tightly
Decontamination: Wash affected area with plenty of water and suitable detergent, dispose of cleaning materials as hazardous waste
Handling: Avoid breathing dust or vapor, minimize contact with skin and eyes, use only in well-ventilated areas, keep containers tightly closed when not in use
Hygiene Measures: Wash hands before breaks and after handling chemical, avoid eating, drinking, or smoking in work area
Storage: Store in cool, dry place out of direct sunlight, keep away from incompatible materials like strong acids, bases, and oxidizers, store below 30°C in original container
Incompatibles: Moisture, strong alkalis, strong oxidizing agents
Exposure Limits: No official limits assigned; minimize exposure by engineering and PPE
Engineering Controls: Use fume hood or local exhaust ventilation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat or apron, closed shoes
Respiratory Protection: Use respirator if exposure limits are exceeded or in confined spaces
Other Controls: Emergency eyewash and shower should be available in work area

Hazardous Polymerization: Will not occur under normal use
Acute Toxicity: Ingestion may cause gastrointestinal upset, animal LD50 (oral, rat) estimated 400–800 mg/kg
Skin Contact: Can cause redness, mild burns, allergic reactions rare but possible
Eye Contact: May cause serious irritation, excessive tearing, blurred vision
Inhalation: Inhalation of aerosol may irritate respiratory tract, cough, mild breathing difficulty
Chronic Exposure: Prolonged skin exposure may lead to dermatitis, no reliable evidence for carcinogenicity or reproductive toxicity
Sensitization: No data suggesting skin or respiratory sensitization
Target Organs: No definitive data, treat as irritant
Aquatic Toxicity: Product is toxic to aquatic life at elevated concentrations; LC50 (fish) not well defined, precaution advised
Persistence/Degradability: Not readily biodegradable, long term impact possible if released repeatedly
Bioaccumulative Potential: Octanol-water partition not available, low volatility suggests limited bioaccumulation
Mobility in Soil: Likely to migrate through soil in aqueous state, avoid release to environment
