Impurities: Negligible, sourced from food-grade raw starch
Mixtures: Not applicable; provided in powdered or granular form only
Inhalation: Move person to fresh air immediately. Get medical advice if cough or discomfort persists.
Skin Contact: Wash affected area with soap and water. Remove contaminated clothing. Seek medical attention if irritation develops.
Eye Contact: Rinse eyes gently but thoroughly with running water for at least 15 minutes, lifting eyelids occasionally. Consult healthcare professional if irritation occurs.
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical advice for large quantities or if feeling unwell.
Note to Physician: Treat symptoms; no special antidotes required as not considered acutely toxic
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Not Suitable Media: Direct water jet, due to possibility of spreading dust
Special Hazards: Thermal decomposition may release carbon monoxide, carbon dioxide, and sodium oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing due to dust or toxic decomposition fumes
Firefighting Instructions: Avoid generating airborne dust; use fine water spray to reduce dust hazard; cool containers with water
Explosion Hazard: Dust can form explosive mixtures with air in confined areas
Personal Precautions: Avoid breathing dust; ventilate area; use personal protective equipment—respirators in case of heavy dust
Environmental Precautions: Keep product out of drains and watercourses if safe to do so; powder is biodegradable but may cause localized turbidity
Cleanup Methods: Shovel or sweep material into suitable containers for reuse or disposal; use dust suppressant like water spray to minimize air dispersal; dispose of waste according to local regulations
Additional Advice: Clean spill area thoroughly as residues can be slippery
Handling: Use only with adequate ventilation. Minimize dust generation. Avoid inhalation, ingestion, and direct contact with powder. Grounds all equipment and machinery to prevent static discharge.
Storage Conditions: Keep containers tightly closed, dry, and stored in a cool, well-ventilated area. Protect from moisture and sources of ignition. Use original packaging or food-safe containers.
Incompatible Materials: Strong oxidizing agents and acids
Storage Life: 2-3 years in sealed container under recommended conditions
Special Requirements: Keep away from dampness; absorbency could change properties
Exposure Limits: No established occupational exposure limit for this product; use general dust exposure limits (e.g., 10 mg/m³ for nuisance dust)
Engineering Controls: Local exhaust ventilation in high-dust environments; process enclosure if feasible
Personal Protective Equipment: Dust mask or NIOSH-approved respirator in heavy dust areas; gloves for sensitive skin; safety goggles where eye contact may occur; protective clothing if repeated exposure likely
Hygiene Measures: Wash hands after use; launder soiled clothing before reuse; avoid eating, drinking, or smoking during handling
Environmental Controls: Avoid release into sewage and waterways; use containment where feasible
Medical Surveillance: Not required for healthy adults handling typical volumes
