Inhalation: Move person to fresh air; seek medical attention if breathing becomes difficult
Skin Contact: Wash contact area with soap and plenty of water for at least 15 minutes; remove contaminated clothing
Eye Contact: Rinse thoroughly with water for at least 15 minutes; consult a physician if irritation persists
Ingestion: Rinse mouth out, do not induce vomiting; seek medical assistance if nausea or other symptoms occur
Most Important Symptoms: Mild irritation to previously mentioned affected areas; no known chronic effects with standard use
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray
Unsuitable Extinguishing Media: High pressure water jet (can spread burning liquid)
Specific Fire Hazards: Product can burn if heated strongly, releasing carbon dioxide and carbon monoxide
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Fire Fighting Instructions: Cool exposed containers with water; avoid inhaling fumes
Combustion Products: Carbon oxides (CO, CO2), acrolein possible in incomplete combustion
Personal Precautions: Ensure adequate ventilation; wear gloves and eye protection
Spill Cleanup: Absorb with inert materials such as sand or earth; collect liquid in proper waste container
Spills on Skin: Wash thoroughly with water and soap after handling
Environmental Precautions: Prevent entry into sewers and waterways; report significant releases to relevant authorities
Disposal: Dispose absorbed material following local environmental regulations
Handling: Use only with proper ventilation; avoid breathing mist or vapor, and avoid skin and eye contact
Storage Conditions: Keep container tightly closed in a cool, dry, well-ventilated space; avoid direct sunlight and sources of ignition
Specific Practices: Store away from strong oxidizers, acids, and bases; label containers clearly
Hygiene Measures: Wash hands thoroughly after use; do not eat, drink, or smoke during handling
Occupational Exposure Limits: No specific limits set for palmitoleic acid; general hygiene and safe laboratory practices apply
Engineering Controls: Handle in areas with adequate ventilation—fume hood preferred for lab settings
Personal Protection: Safety goggles, lab coat, chemical-resistant gloves, and, where vapor is present, a respirator
Environmental Exposure Controls: Prevent spills and keep out of aquatic environments wherever feasible
Appearance: Colorless to pale yellow, oily liquid
Odor: Mild, fatty

Respiratory Sensitization: No data indicating respiratory sensitization
Skin Sensitization: Not expected; rare cases of allergy possible after repeated contact
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA
Reproductive Toxicity: No evidence of effects reported in scientific literature
Mutagenicity: No mutagenic activity reported
Chronic Effects: Chronic exposure expected to produce minimal health impacts; based on long-term dietary exposure to similar fatty acids
Environmental Fate: Readily biodegradable in soil and water
Bioaccumulation Potential: Low, given rapid breakdown and metabolic use in living organisms
Aquatic Toxicity: Not expected to be toxic at concentrations normally encountered in environment
Toxicity to Fish and Daphnia: LC50 > 100 mg/L (extrapolated from closely related fatty acids)
Persistence and Degradability: Complete degradation expected in natural conditions
Mobility in Soil: Low due to high partition coefficient (binds to organic matter)
Other Adverse Effects: No known significant effects or hazards; large spills may affect oxygen levels in aquatic systems by forming surface films
Disposal of Product: Collect waste in clearly labeled suitable containers; treat as non-hazardous organic waste unless contaminated
Disposal of Packaging: Triple rinse containers, puncture, and send for recycling or landfill per local regulations
