Main Ingredient: Methyl Undecanoate
Chemical Formula: C12H24O2
CAS Number: 111-81-9
Purity: Usually above 98% in laboratory standards
Inhalation: Get fresh air, support breathing if irritation occurs, and seek medical advice if discomfort lingers
Skin Contact: Wash affected area with soap and water, remove contaminated clothing, seek medical advice for persistent reactions
Eye Contact: Rinse thoroughly with clean water for several minutes, seek medical attention if irritation persists
Ingestion: Rinse mouth, avoid inducing vomiting, seek medical help for large exposures
Extinguishing Media: Use foam, carbon dioxide, dry chemical; avoid using water jets directly
Specific Hazards: Can give off dense smoke, carbon oxides as burning products
Protective Equipment: Firefighters require protective suit and breathing apparatus due to toxic fumes produced in combustion
Personal Protection: Wear gloves and goggles to prevent contact, ensure adequate ventilation
Environmental Precautions: Prevent entry into drains or water systems, contain spill with inert material
Clean Up Methods: Absorb with sand or vermiculite, collect into containers for safe disposal
Handling: Minimize skin and eye contact, avoid inhalation of vapors, use only in well-ventilated spaces
Storage: Store in tightly closed original container, keep in a cool and dry area, keep away from sources of ignition
Incompatibilities: Strong oxidizers and acids should be kept separate
Engineering Controls: Work in adequately ventilated areas, use fume hoods for larger-scale operations
Respiratory Protection: Not usually required, NIOSH/MSHA approved respiratory protection recommended for high vapor concentrations
Skin Protection: Nitrile or neoprene gloves, long sleeves to reduce exposure
