Composition / Information on Ingredients

Main Ingredient: Flaxseed Oil (Linum usitatissimum) - 100%
Constituents: Major fatty acids include Alpha-Linolenic Acid (up to 60%), Linoleic Acid, Oleic Acid, Palmitic Acid, Stearic Acid
Impurities/Additives: Unlikely unless mixed for industrial or dietary purposes; consult supplier

First Aid Measures

Inhalation: Remove to fresh air, respiratory irritation is rare, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash exposed skin with soap and water, mild reactions only
Eye Contact: Flush eyes with water for several minutes, remove contact lenses, seek medical attention for persistent irritation
Ingestion: Rinse mouth, drink water, do not induce vomiting, medical attention for discomfort beyond mild digestive upset
Most Important Symptoms: Mild skin or eye irritation, mild gastrointestinal discomfort if ingested in large amounts
Medical Attention Needed: Unlikely in most cases, advise in case of allergic reaction or severe discomfort

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, sand; avoid high-pressure water
Unsuitable Media: Strong water jets can spread burning oil
Hazardous Combustion Products: Dense smoke, acrolein, carbon monoxide, carbon dioxide
Specific Hazards: Oil-saturated rags may self-heat, risk of spontaneous combustion
Protective Equipment: Firefighters use self-contained breathing apparatus and protective clothing
Special Precautions: Remove containers from fire area, cool exposed containers with water
Flammability Limits: Not easily ignitable but combustible at elevated temperatures

Accidental Release Measures

Personal Precautions: Wear gloves, avoid slipping hazard due to spilled oil
Environmental Precautions: Prevent entry into drains, waterways, and soil; large spills can pose risk to aquatic life
Methods for Cleaning Up: Absorb with earth, sand, or inert absorbent, collect with non-sparking tools
Disposal: Place waste in suitable closed containers for disposal according to local requirements

Handling and Storage

Handling: Use with adequate ventilation, avoid contact with eyes or prolonged skin exposure, keep away from sources of ignition, do not reuse oil-soaked cloths without proper laundering
Storage Conditions: Store in tightly closed containers, in a cool, dry, well-ventilated place away from heat and sunlight
Incompatibilities: Strong oxidizers, acids, strong alkalis
Special Precautions: Keep separated from foodstuffs intended for consumption until safety compliance verified

Exposure Controls and Personal Protection

Engineering Controls: General room ventilation
Personal Protective Equipment: Protective gloves to avoid skin contact, protective goggles for splash risk
Respiratory Protection: Not generally required, use mask in case of aerosol generation
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing
Exposure Limits: No established occupational exposure limits for flaxseed oil
