Concentration: >99% by weight
Impurities: Trace amounts of stabilizers or inhibitors for storage
CAS Number: 100-40-3
Other Components: No significant contaminants reported that contribute to hazard classification
Inhalation: Remove to fresh air immediately, support breathing, seek medical help for breathing difficulty or if irritation persists
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water, use soap, obtain medical attention for persistent irritation
Eye Contact: Flush eyes for at least 15 minutes with running water, separate eyelids by hand, get medical aid if irritation continues
Ingestion: Do not induce vomiting, rinse mouth, drink water if conscious, call poison control and get immediate emergency medical attention
Note to Physicians: Treat according to symptoms, ensure supportive measures for respiratory or neurological effects
Suitable Extinguishing Media: Dry chemical, alcohol-resistant foam, carbon dioxide; use water spray for cooling exposed containers
Special Hazards of Combustion: Produces toxic vapors including carbon monoxide, carbon dioxide, and possible acrid smoke in fire
Advice for Firefighters: Wear self-contained breathing apparatus, full protective gear; approach from upwind
Explosion Sensitivity: Vapors may form explosive mixtures in air, use non-sparking tools; containers may explode with heat exposure
Other Considerations: Avoid run-off into sewers and waterways; use caution for re-ignition and film residues
Personal Precautions: Evacuate area, ventilate space, use protective equipment for skin, eyes, and respiratory system
Environmental Precautions: Keep chemical from drains, waterways; notify appropriate authorities for uncontrolled releases
Methods for Containment and Cleanup: Absorb with earth, sand, or non-combustible material; collect in sealed non-sparking containers for disposal; ventilate area well, clean surfaces with water and detergent after material removal
Safe Handling: Use only with proper ventilation; avoid sources of heat, sparks, or flame; prevent breathing vapor or contact with skin and eyes
Storage Requirements: Store in tightly closed containers, cool, dry, well-ventilated area away from direct sunlight, oxidizers, acids
Incompatibilities: Strong oxidizing agents, strong acids, peroxides
Other Precautions: Use grounded equipment, proper labeling, limit amounts in work areas, keep away from food or feed storage
Occupational Exposure Limits: No established OSHA or ACGIH TLV, minimize exposure as much as possible
Engineering Controls: Fume hood or local exhaust ventilation required; use explosion-proof electrical equipment
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash goggles or face shield, impervious protective clothing, staff should use supplied air respirators where ventilation does not control exposure
Hygiene Measures: Wash thoroughly after handling, do not eat, drink, or smoke in work area, keep work clothing separate from street clothing

Carcinogenicity: IARC Group 2B (possibly carcinogenic to humans based on animal data)
Reproductive Toxicity: Not sufficiently studied, use precaution
Chronic Effects: Potential liver and kidney injury, central nervous system effects from repeated or high exposures
Other Information: Prolonged or repeated exposure increases risk of adverse effects, especially in poorly ventilated spaces
Aquatic Toxicity: Harmful to aquatic life, specific data limited
Persistence and Degradability: Slow biodegradation in environment, potential for persistence
Bioaccumulation Potential: Log Kow suggests risk of bioaccumulation
Mobility in Soil: Low solubility, moderate mobility due to volatility
Other Adverse Effects: May poison aquatic organisms by direct contact or through bioaccumulation
Disposal Methods: Dispose as hazardous organic solvent according to local, state, and federal regulations
Waste Treatment: Incineration in approved facilities preferred, avoid direct release to water bodies
Container Disposal: Triple rinse containers, puncture or crush, send to licensed drum reconditioner or hazardous waste facility
