Chemical Name: 1-Octyne
CAS Number: 629-05-0
Concentration: ≥98% by weight
Impurities: Trace hydrocarbons or other related alkynes (typically less than 2%)
Stabilizers or Additives: None typically present; refer to batch certificate for specific details
Inhalation: Move exposed person to fresh air immediately; rest in comfortable breathing position; seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing; wash affected area with plenty of soap and water for at least 15 minutes; seek medical aid if irritation persists
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if easy to do; continue rinsing and seek medical help promptly
Ingestion: Do not induce vomiting; rinse mouth with water; seek immediate medical advice or attention
Most Important Symptoms: Burning, irritation, coughing, dizziness, drowsiness; prolonged exposure may worsen effects
Advice for Medical Personnel: Treat symptomatically; monitor respiratory and nervous system functions
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or alcohol-resistant foam
Unsuitable Media: Water jets likely spread flames; do not use for direct extinguishing
Specific Hazards: Vapors form explosive mixtures with air; fire produces toxic gases such as carbon monoxide and carbon dioxide
Special Equipment and Precautions: Firefighters should use full protective gear and self-contained breathing apparatus; stay upwind and isolate hazard area
Additional Information: Containers exposed to fire may burst; cool containers with water spray from a safe distance
Personal Precautions: Evacuate area; isolate hazard zone; avoid breathing vapor; use proper personal protective equipment
Environmental Precautions: Prevent release to drains, sewers, and waterways; notify authorities if product causes environmental contamination
Clean-Up Methods: Eliminate ignition sources; ventilate area; absorb spill with inert material like sand or earth; collect in compatible container for disposal
Decontamination: Wash spill site after clean-up; ensure adequate ventilation
Waste Disposal: Dispose of material in accordance with local, regional, national, international regulations
Handling Recommendations: Use in well-ventilated areas; avoid sources of ignition, static discharge, and open flames; wear recommended protective gear; keep away from oxidizing agents
Storage Conditions: Store in tightly closed containers; keep in cool, dry, ventilated place; secure from unauthorized access
Incompatibilities: Oxidizing agents, acids, alkalis, halogens; avoid strong sunlight
General Hygiene: Wash hands thoroughly after handling; do not eat, drink, or smoke in work area; provide eyewash stations and safety showers near workstations
Occupational Exposure Limits: None established by OSHA, NIOSH, or ACGIH for 1-Octyne
Engineering Controls: Use adequate local exhaust or general ventilation to keep vapor concentrations below recommended exposure limits
Personal Protective Equipment: Chemical-resistant gloves, eye protection (goggles or face shield), protective clothing, flame-resistant lab coat
Respiratory Protection: Use NIOSH approved organic vapor respirator if exposure limits are exceeded or if ventilation is insufficient
Hygiene Measures: Change contaminated clothing promptly, wash hands before breaks and after work, regularly inspect PPE for damage
