Hazard Identification

Classification: Not classified as hazardous according to GHS (Globally Harmonized System)
Main Hazards: May cause mild eye, skin, or respiratory irritation for sensitive individuals
Pictogram: No symbol required
Signal Word: None
Precautionary Statements: Avoid inhaling dust, prevent contact with eyes; keep away from strong oxidizers
Health Effects: Excess intake by ingestion may cause gastrointestinal discomfort, diarrhea

Composition / Information on Ingredients

Substance: Sorbitol
Concentration: 97–100% pure
Impurities: Minimal, trace sugars like mannitol may be present
Chemical Family: Sugar alcohols (polyols)

First Aid Measures

Inhalation: Move to fresh air; seek medical attention if symptoms persist or breathing becomes difficult
Skin Contact: Wash contact area thoroughly with soap and water, remove soiled clothing
Eye Contact: Flush eyes with water for several minutes, remove contact lenses if easy to do; seek medical help if redness or irritation continues
Ingestion: Rinse mouth with water, drink water to dilute; if large quantities are swallowed and symptoms develop, consult a healthcare provider

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide to extinguish
Specific Hazards: Combustible dust can form explosive mixtures in air if powdered
Hazardous Combustion Products: Carbon monoxide, carbon dioxide may form in a fire
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full protective gear
Special Procedures: Avoid using water jet as this may spread burning material; keep containers cool with water spray

Accidental Release Measures

Personal Protection: Wear safety goggles, gloves, dust mask
Environmental Precautions: Avoid release into drains, sewers, natural waterways
Clean-Up Methods: Sweep up without creating dust, collect in appropriate container for disposal; ventilate spill area; wash area after material pickup

Handling and Storage

Handling: Minimize dust generation; avoid breathing dust; use with adequate ventilation
Storage: Store tightly closed in a dry, cool, well-ventilated area away from heat sources and incompatible substances like strong oxidizers
Safe Storage Details: Keep container tightly sealed when not in use; protect from moisture; segregate from strong acids and bases

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limit for sorbitol
Engineering Controls: Provide local exhaust or general ventilation to reduce exposure to dust
Personal Protective Equipment: Wear safety glasses with side shields, lightweight gloves, dust mask if powder form is handled
Hygiene Measures: Wash hands after handling, remove contaminated clothing and wash before reuse
