Chemical Name: N-Propyl N-Valerate
Concentration: >99%
Impurities: Minimal, consult supplier for detailed impurity profile
Other Components: No significant hazardous impurities known based on supplier data
General Advice: Move person away from source of exposure and seek medical attention as needed.
Inhalation: Move affected person to fresh air. Monitor for respiratory distress. Provide oxygen or artificial respiration if breathing becomes difficult.
Skin Contact: Wash affected skin thoroughly with soap and water. Remove contaminated clothing and launder before reuse. If irritation persists, consult medical advice.
Eye Contact: Rinse eyes immediately with large amounts of water for at least 15 minutes. Hold eyelids apart while rinsing. Obtain medical attention if discomfort continues.
Ingestion: Rinse mouth with water. Never induce vomiting unless directed by medical personnel. Seek prompt medical attention.
Suitable Extinguishing Media: Alcohol-resistant foam, carbon dioxide, dry powder, water spray. Avoid using water jet, which may spread material.
Specific Hazards: Vapors may form flammable mixtures in air. Upon combustion, may produce carbon monoxide and carbon dioxide.
Special Protective Equipment for Firefighters: Firefighters should wear self-contained breathing apparatus and full protective gear.
Additional Information: Cool exposed containers with water spray to prevent pressure buildup. Evacuate area and keep upwind of fire.
Personal Precautions: Wear chemical-resistant gloves, eye protection, and suitable respiratory protection. Remove sources of ignition. Evacuate unnecessary personnel.
Environmental Precautions: Prevent product from entering drains, stormwater, or soil. If contaminated water reaches waterways, notify relevant authorities.
Methods for Cleanup: Contain spill with inert absorbent material like sand or earth. Sweep or scoop up into approved containers for disposal. Ventilate area to clear vapors.
Handling: Use only in areas with adequate ventilation. Avoid skin and eye contact. Prohibit smoking and open flame near operations. Use proper grounding and bonding to prevent static discharge. Follow good personal hygiene practices.
Storage: Store in tightly closed containers in a cool, dry place. Keep away from heat sources, ignition points, and incompatible substances such as strong oxidizers. Protect from sunlight. Store below 30 °C for optimal shelf-life. Keep containers labeled and upright.
Exposure Limits: No occupational exposure limits established for N-Propyl N-Valerate. Follow general workplace limits for organic esters if available.
Engineering Controls: Use local exhaust or general dilution ventilation to keep vapor concentrations low.
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), safety glasses or goggles, protective clothing, suitable respiratory protection in poorly ventilated environments.
Hygiene Measures: Wash hands before breaks, after handling, and after using the bathroom. Remove contaminated clothing and launder before reuse. Do not eat, drink, or smoke in areas where product is handled.
