GHS Classification: Flammable liquid (Category 2); Acute toxicity, inhalation (Category 4); Skin irritation (Category 2); Specific target organ toxicity, single exposure (Category 3, Narcotic effects) Signal Word: Danger GHS Labels: Flame, Exclamation mark Hazard Statements: Highly flammable liquid and vapor; harmful if inhaled; causes skin irritation; may cause drowsiness or dizziness Precautionary Statements: Keep away from heat, sparks, open flames; use explosion-proof equipment; wear protective gloves; avoid breathing vapors; wash thoroughly after handling; take precautions against static discharge
Substance: Isoheptene Concentration: ≥98% Impurities: C7 hydrocarbons, trace amounts of hexenes or octenes Hazardous Components: None classified as more hazardous than parent compound at present concentration; check batch-specific certificate of analysis for minor impurities Other Identifying Data: Hydrocarbon family, unsaturated alkene structure
Inhalation: Move affected person to fresh air; keep at rest; seek medical attention if symptoms persist Skin Contact: Remove contaminated clothing; wash skin with plenty of soap and water; seek medical attention if irritation develops Eye Contact: Flush eyes cautiously with water for at least fifteen minutes; remove contact lenses if easy; get medical help if symptoms occur Ingestion: Rinse mouth; do not induce vomiting; seek immediate medical attention Most Important Symptoms: Dizziness, headache, irritation to respiratory system, skin and eye redness or discomfort Note for Physicians: Treat symptomatically; monitor for respiratory depression and central nervous system effects
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water fog Unsuitable Extinguishing Media: Direct water jet (spreads fire hazard) Flammable Properties: Vapors may form explosive mixtures with air; heavier than air and may travel along ground to ignition sources Special Protective Equipment: Full protective suit and self-contained breathing apparatus for fire fighters Hazards from Combustion: Emits toxic fumes such as carbon monoxide, carbon dioxide, alkenes; risk of flash back Advice for Firefighters: Evacuate area; cool containers with water spray if exposed to fire; dispose of fire debris and contaminated extinguishing water in accordance with regulations
Personal Precautions: Evacuate unprotected personnel; ensure ventilation; avoid breathing vapors; use non-sparking tools and intrinsic safety measures Protective Equipment: Chemical-resistant gloves, goggles, coveralls, suitable respiratory protective device Environmental Precautions: Prevent further leaks or spillage if safe to do so; keep product out of drains, surface water, and soil Containment Methods: Stop source of leak if safe; use inert absorbent material such as sand or earth for large spills Cleanup Procedures: Collect in labeled, sealed containers for disposal; ventilate area; dispose of in accordance with local environmental regulations
Safe Handling Guidelines: Work in well-ventilated areas; avoid contact with skin and eyes; avoid inhaling vapors; prohibit smoking in handling areas; use flameproof electrical equipment Storage Requirements: Store in tightly closed containers in a cool, well-ventilated, and dry area away from sources of ignition, oxidizers, and acids Incompatible Materials: Strong oxidizing agents, acids, halogens Safe Transfer Techniques: Use grounded and bonded containers and equipment to avoid static discharge Special Precautions: Keep containers sealed when not in use to limit evaporation
Exposure Limits: No occupational exposure limit values for isoheptene set by OSHA, ACGIH, or NIOSH; use hydrocarbon vapor guidelines (<300 ppm for similar alkenes) Engineering Controls: Local exhaust ventilation, explosion-proof ventilation systems, vapor detection alarms Respiratory Protection: NIOSH-approved organic vapor respirator under conditions exceeding recommended exposure levels Skin Protection: Chemical-resistant gloves (nitrile, neoprene), antistatic protective clothing Eye/Face Protection: Safety goggles, faceshield for high splash risk Hygiene Measures: Wash hands and face before eating, drinking, or smoking; remove contaminated clothing promptly
Appearance: Colorless, mobile liquid Odor: Gasoline-like, hydrocarbon odor Odor Threshold: Not established pH: Not applicable Melting Point/Freezing Point: -126°C Boiling Point: 99°C Flash Point: -1°C (closed cup) Evaporation Rate: Rapid Flammability: Highly flammable Upper/Lower Explosion Limits: 1.1% – 6.4% (by volume in air) Vapor Pressure: 85 mmHg at 20°C Vapor Density: >3 (air = 1) Relative Density: 0.69–0.71 g/cm³ Solubility: Insoluble in water, miscible with common organic solvents Partition Coefficient (n-octanol/water): 4.2 Auto-ignition Temperature: 250°C Decomposition Temperature: Not established Viscosity: Low
Chemical Stability: Stable under recommended storage conditions, prone to oxidation and polymerization with extended exposure to air or light Reactivity: Forms unstable peroxides upon prolonged contact with oxygen Incompatible Materials: Strong oxidizing agents, acids, organometallic catalysts, peroxides Decomposition Products: Carbon monoxide, carbon dioxide, and unidentifiable toxic vapors Hazardous Polymerization: May occur under heat, light, or catalyst contamination Conditions to Avoid: Heat, open flame, ignition sources, prolonged air exposure, direct sunlight
Acute Toxicity: Low oral toxicity; inhalation causes central nervous system depression (headache, nausea, dizziness); skin contact results in dryness, defatting, and mild local irritation Chronic Effects: Prolonged or repeated exposure may cause dermatitis or sensitization; long-term risks not fully evaluated Routes of Exposure: Inhalation, dermal contact, ingestion Carcinogenicity: Not classified by IARC, NTP, or OSHA as a human carcinogen Mutagenicity: No data indicating mutagenic potential in laboratory studies Reproductive Toxicity: Insufficient data for evaluation Other Health Effects: Acting as a simple asphyxiant, affects central nervous system at high concentrations; aspiration hazard if swallowed
Aquatic Toxicity: Toxic to aquatic life; hydrocarbon compounds bioaccumulate in organisms Persistence and Degradability: Not readily biodegradable; volatilizes rapidly from water and soil Mobility: Moves quickly in air due to volatility; limited partitioning into soil or sediment Bioaccumulation Potential: Moderate; tends to concentrate in lipid-rich tissues of aquatic organisms Other Adverse Effects: Spills threaten aquatic and soil habitats; long degradation period increases exposure risk for local biota
Disposal Methods: Collect as hazardous waste; utilize licensed contractor for incineration or approved fuel blending Contaminated Packaging: Empty containers must follow hazardous waste protocols; do not reuse containers Environmental Precautions: Dispose of in compliance with federal, state, and local environmental controls; never discharge into waterways, storm drains, or unapproved landfills Special Recommendations: Maintain documentation of waste disposal and recovery for audit and compliance purposes
UN Number: UN3295 UN Proper Shipping Name: Hydrocarbons, liquid, n.o.s. (Isoheptene) Transport Hazard Class: 3 (Flammable liquids) Packing Group: II DOT Hazard Label: Flammable liquid Environmental Hazards: Marine pollutant Special Transport Requirements: Use explosion-proof vehicles, proper placarding, secure tightly against shifting or spillage; follow emergency response protocols Regulatory References: Check IATA, IMDG, ADR, and other applicable international guidelines
