Chemical Name: 2-Piperidinoethanol
CAS Number: 2008-75-5
Concentration: 98-100% (product is typically sold as a pure substance for laboratory and industrial use)
Impurities: Residual water content <1%, possible minor byproducts from synthesis (trace amines)
Other Additives: None in standard commercial material
Inhalation: Remove person to fresh air immediately. Keep comfortable for breathing. Get medical advice if symptoms persist.
Skin Contact: Remove contaminated clothing. Rinse skin with plenty of water for at least 15 minutes. Seek medical attention for persistent irritation.
Eye Contact: Rinse cautiously with water for at least 15 minutes, holding eyelids open. Remove contact lenses if present and easy to do. Seek medical help if irritation or discomfort continues.
Ingestion: Rinse mouth. Do not induce vomiting. Drink water if alert. Get emergency medical help promptly.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Select extinguishing media based on surrounding materials.
Specific Hazards: Vapors may be irritating. Combustion creates toxic fumes, including carbon oxides and nitrogen oxides.
Protective Equipment: Firefighters use full protective gear and self-contained breathing apparatus.
Special Procedures: Contain runoff to prevent environmental contamination. Remove containers from fire area if safe.
Personal Precautions: Avoid breathing vapors and skin contact. Ventilate area. Remove all incompatible materials.
Protective Equipment: Use gloves, splash goggles, lab coat, and vapor mask as appropriate.
Spill Cleanup: Contain and absorb spill with inert material (sand, earth). Collect material in a labeled chemical waste container. Wash area with water.
Disposal: Dispose of collected waste and cleanup materials through a licensed chemical waste contractor.
Environmental Precautions: Prevent release into drains, watercourses, or ground.
Handling: Avoid skin and eye contact. Do not inhale vapors or mist. Work in a fume hood or with adequate ventilation. Use non-sparking tools and equipment rated for flammable chemicals.
Hygiene: Wash hands thoroughly after handling. Take off contaminated clothing and launder before reuse.
Storage Conditions: Store in tightly closed container. Keep in a well-ventilated, cool, dry place. Clearly label all containers.
Incompatible Materials: Strong oxidizers, acids, acyl halides.
Exposure Limits: No OSHA or ACGIH limits established specifically for 2-Piperidinoethanol. Use engineering controls as a preventive measure.
Engineering Controls: Fume hood or local exhaust. Safety shower and eyewash station in the work area.
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), lab coat, chemical splash goggles, face shield if splashing risk, NIOSH-approved respirator if ventilation is inadequate.
Special Requirements: No eating, drinking, or smoking while handling. Change gloves frequently.
