GHS Classification: Flammable Liquid (Category 2); Skin Irritant (Category 2); Eye Irritant (Category 2A); Acute Toxicity, Oral (Category 4); Aspiration Hazard (Category 1)
Signal Word: Danger
Hazard Statements: Highly flammable liquid and vapor; causes skin and eye irritation; may cause respiratory irritation; may be fatal if swallowed and enters airways
Pictograms: Flame, exclamation mark, health hazard
Precautionary Statements: Keep away from heat, sparks, open flames, hot surfaces; avoid all ignition sources; use only non-sparking tools; avoid breathing vapors and skin contact
Chemical Name: 1-Octene
CAS Number: 111-66-0
Concentration: >99%
Impurities: Trace amounts of higher and lower alkenes; total impurities <1%
Inhalation: Move affected person to fresh air; if breathing is difficult, qualified personnel must give oxygen; get medical attention if symptoms persist
Skin Contact: Remove contaminated clothing immediately and wash skin with soap and water for several minutes; seek medical attention for persistent irritation
Eye Contact: Flush eyes carefully with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally; obtain medical attention quickly
Ingestion: Do not induce vomiting to avoid aspiration into lungs; rinse mouth and seek immediate medical attention
Most Important Symptoms: Irritation of eyes, skin, respiratory tract; risk of chemical pneumonitis if aspirated
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, CO2, water spray (mist)
Unsuitable Extinguishing Media: Direct water jets (may spread fire)
Specific Hazards: Highly flammable vapor may form explosive mixtures with air; combustion releases carbon monoxide, carbon dioxide, and other unidentified toxic fumes
Protective Equipment: Self-contained breathing apparatus and full protective gear required
Additional Advice: Evacuate area; use water spray to cool containers exposed to fire; dike runoff water to prevent environmental contamination
Personal Precautions: Evacuate unnecessary personnel; eliminate ignition sources; ventilate area; avoid skin and eye contact
Protective Equipment: Chemical-resistant gloves, goggles, flame-resistant clothing, antistatic footwear
Emergency Procedures: Stop leak if safe; use non-sparking tools
Containment Methods: Prevent entry into drains, soil, or watercourses
Clean-Up Methods: Absorb spill with non-combustible material (sand, earth, vermiculite), place in suitable container for disposal, wash spill site after material pickup
Handling: Keep away from heat, sparks, and open flame; use only in well-ventilated areas; ground containers during transfer; avoid breathing vapors; avoid contact with skin and eyes; use antistatic measures
Storage: Store in tightly closed containers in a cool, well-ventilated location equipped with explosion-proof electrical installations; keep container upright and away from incompatible materials such as oxidizers; post “No Smoking” signs
Storage Temperature: Keep below 35°C
Incompatible Materials: Strong oxidizing agents, acids
Occupational Exposure Limits: No OSHA PEL; ACGIH TLV not established; minimize exposure as recommended by chemical hygiene practices
Engineering Controls: Local exhaust ventilation, explosion-proof ventilation, process enclosures where feasible
Personal Protective Equipment: Safety goggles or face shield, flame-resistant gloves, long-sleeved clothing, chemical apron
Respiratory Protection: NIOSH-approved organic vapor respirator if vapor concentrations exceed limits
Hygiene Measures: Wash thoroughly after handling; remove contaminated clothing and wash before reuse; ensure eyewash stations and safety showers are accessible
