Inhalation: Move individual to fresh air immediately, keep at rest in position comfortable for breathing, get medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash affected area well with soap and water, seek medical advice if irritation develops
Eye Contact: Rinse gently with plenty of water for at least 15 minutes, remove contact lenses if present, consult an ophthalmologist if discomfort continues
Ingestion: Do not induce vomiting, rinse mouth, seek prompt medical attention to assess risk of aspiration and other effects
Most Important Symptoms: Respiratory irritation, dizziness, headache, skin irritation, redness, coughing
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray (do not use direct water jet)
Specific Hazards: Vapors may form explosive mixtures with air, combustion produces carbon monoxide and carbon dioxide
Protective Equipment: Self-contained breathing apparatus and full protective suit for firefighters
Advice for Firefighters: Cool containers with water, avoid inhalation of vapors, ventilate area
Personal Precautions: Remove sources of ignition, use personal protective equipment recommended in section on Exposure Controls
Environmental Precautions: Prevent spillage from entering drains, sewers, or waterways, notify authorities if significant contamination occurs
Containment and Clean Up: Stop leak if safe to do so, absorb spill with inert material (sand, vermiculite), place in container for disposal, ventilate area thoroughly, wash spill site after material pickup
Handling: Use only in well-ventilated areas, avoid inhalation of vapors and contact with skin and eyes, keep away from heat, sparks, and open flames, electrically bond and ground containers
Storage: Store in tightly closed original container, in a cool, well-ventilated, flammable liquid storage area, segregate from strong oxidizers and acids, keep away from sunlight and ignition sources
Occupational Exposure Limits: No established US OSHA or ACGIH limits; recommend using limits for similar alkenes: TWA 500 ppm
Engineering Controls: Provide appropriate exhaust ventilation; explosion-proof equipment recommended
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, flame-retardant clothing, respiratory protection (organic vapor cartridge mask) if airborne concentrations are high
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke near material

Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, various hydrocarbons during combustion
Conditions to Avoid: Heat, sparks, open flames, static discharge, strong oxidizing agents
Acute Toxicity: Harmful if inhaled; symptoms include headache, dizziness, and nausea, may produce narcosis at high concentrations
Skin Corrosion/Irritation: Causes moderate irritation with prolonged or repeated exposure
Eye Damage/Irritation: Causes irritation, tearing, redness
Respiratory or Skin Sensitization: No reliable data on sensitizing properties
Chronic Effects: Prolonged or repeated exposure can cause central nervous system effects
Carcinogenicity/Mutagenicity: No data indicating significant carcinogenic or mutagenic risk at typical occupational exposures
Aquatic Toxicity: Moderately toxic to aquatic organisms, may cause long-term effects in the aquatic environment
Persistence and Degradability: Volatilizes from water and soil, biodegrades slowly in environment
Bioaccumulative Potential: Moderate potential for bioaccumulation
Mobility in Soil: High, due to volatility and low water solubility
Other Adverse Effects: Spills can cause localized harm to plant and animal life near affected waters or soils
Waste Treatment Methods: Dispose by controlled incineration in accordance with local, state, and federal regulations
Contaminated Containers: Triple rinse, puncture, and recycle or transport for hazardous waste disposal
Precautions: Do not dump into sewers, waterways, or on soil, consult with licensed waste disposal company for proper handling
