GHS Classification: Not classified as hazardous per OSHA Hazard Communication Standard; may cause mild skin and eye irritation
Hazard Statements: May cause slight irritation to eyes or skin on prolonged exposure; no known acute or chronic hazards under normal use
Precautionary Statements: Avoid direct contact with eyes and prolonged contact with skin; proper lab hygiene reduces risk of discomfort
Signal Word: None required
Potential Health Effects: Ingestion may produce mild gastrointestinal symptoms; inhalation unlikely due to low volatility
Chemical Name: Docosahexenoic Acid
Common Synonyms: DHA
Purity: >98% (typical for laboratory grade)
Impurities: Trace fatty acids (if present, may include eicosapentaenoic acid, linoleic acid)
Molecular Weight: 328.49 g/mol
Eye Contact: Rinse with copious amounts of water for 15 minutes, remove contact lenses if present, seek medical attention if irritation persists
Skin Contact: Wash area thoroughly with soap and water, remove contaminated clothing, contact physician if redness or discomfort develops
Ingestion: Rinse mouth with water, drink water to dilute, do not induce vomiting, consult a healthcare provider for persistent gut symptoms
Inhalation: Move to fresh air, get medical help for coughing or shortness of breath
Most Important Symptoms: Mild irritation possible; serious effects not common
Suitable Extinguishing Media: Foam, dry chemical, CO2, or water spray
Unsuitable Extinguishing Media: Direct stream of water can cause fire to spread
Specific Hazards: May emit toxic fumes such as CO, CO2 under fire conditions
Protective Equipment: Firefighters should wear self-contained breathing apparatus and protective gear
Special Procedures: Cool containers with water spray, avoid inhaling combustion products, isolate fire area if safe to do so
Personal Precautions: Wear gloves, eye protection, avoid contact with skin and eyes
Methods for Containment: Stop leak with inert absorbent material (vermiculite, sand), prevent run-off to drains
Cleanup Procedures: Collect residue in suitable closed containers for disposal, wash spill site with soap and water after cleanup completed
Disposal: Refer to Section 13 for disposal guidance
Handling: Use in well-ventilated area, avoid repetitive skin contact, minimize splashing and aerosol generation
Storage: Keep in original tightly closed container, store in a cool, well-ventilated place, protect from heat and light, refrigerate for long-term stability
Incompatible Materials: Strong oxidizers, strong bases
Considerations: Use clean utensils when handling, keep away from food and drink to avoid accidental ingestion
Exposure Limits: No occupational exposure limits established by OSHA, ACGIH, or NIOSH
Engineering Controls: Use with local exhaust ventilation; equipment should be easy to clean to avoid residue buildup
Personal Protective Equipment: Nitrile or rubber gloves, safety glasses, laboratory coat, avoid open-toed shoes
Hygiene Measures: Wash hands thoroughly after handling, remove and wash contaminated clothing before reuse
