Impurities: Small traces of related Vitamin B1 derivatives and manufacturing residues considered non-hazardous
Additional Components: May contain less than 2% moisture as water or bound solvent from storage conditions

First Aid Measures

Inhalation: Remove from exposure, breathe fresh air, seek medical attention if symptoms develop or persist
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical help if discomfort continues
Skin Contact: Wash with plenty of soap and water, remove contaminated clothing, medical guidance needed if irritation continues
Ingestion: Rinse mouth with water, drink small amounts of water if conscious, avoid inducing vomiting unless directed by medical personnel, consult a doctor for significant amounts

Fire-Fighting Measures

Extinguishing Media: Use dry chemical, CO2, water spray or foam
Hazardous Combustion Products: Carbon oxides, nitrogen oxides, hydrogen chloride gas, sulfur oxides created if burnt
Fire Fighting Instructions: Wear full protective gear including self-contained breathing apparatus, avoid exposure to fumes
Additional Precautions: Do not allow fire run-off to reach drains or watercourses, control contaminated fire water for safe disposal

Accidental Release Measures

Personal Precautions: Wear suitable personal protective equipment such as gloves, goggles, dust mask
Spill Procedures: Sweep up avoid creating dust, transfer into suitable containers for disposal, ventilate area
Environmental Precautions: Prevent further leakage, do not let product enter drains
Clean-up Methods: Use water dampened cloth to finish area, dispose of absorbents and solid waste according to regulations

Handling and Storage

Handling: Handle in well-ventilated areas, minimize dust generation, avoid contact with skin and eyes, wash thoroughly after handling
Storage: Store in tightly closed container, away from light, heat, and moisture, keep in a cool, dry place
Incompatible Materials: Strong oxidizers, strong acids, avoid contact with these for stability reasons
Additional Storage Advice: Use original container whenever possible, label containers, practice regular inventory rotation for stock

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation or work in fume hood if available
