Medical Attention: Seek if irritation, shortness of breath, or discomfort persist after exposure
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Unsuitable Media: None known
Hazards during Fire: Product is non-flammable. No hazardous combustion products expected under normal conditions.
Protection for Firefighters: Self-contained breathing apparatus and full protective gear as with all chemical fires
Explosion Data: No risk of explosion under normal handling, but fine dust may contribute to dust explosion in confined spaces
Precautions: Avoid raising dust during firefighting. Dike runoff water to prevent environmental contamination.
Personal Precautions: Avoid inhaling dust. Wear protective gloves, goggles, and dust mask.
Environmental Precautions: Prevent product from entering drains, waterways, or soil in quantity
Methods for Cleaning Up: Use dry methods (shovel, vacuum with HEPA filter) to pick up spilled material. Avoid creating airborne dust. Wash area with water. Collect in suitable closed containers for disposal
Decontamination: Rinse spill area with plenty of water to remove residue
Handling: Use with adequate ventilation. Minimize dust generation. Handle only with clean, dry equipment. Wash hands before eating or drinking.
Storage Conditions: Store in a cool, dry area in tightly closed original packaging. Keep away from incompatible materials (strong acids, strong bases). Protect from moisture to preserve product qualities.
Special Requirements: Keep container tightly sealed. Avoid storing above 25°C/77°F if possible.
Hygiene Practices: Do not eat, drink, or smoke in area where product is handled.
Occupational Exposure Limits: No established limits for tripotassium citrate
Engineering Controls: Use local exhaust or general dilution ventilation. Enclose processes as much as feasible.
Respiratory Protection: Dust mask or respirator (NIOSH-approved) if exposure might exceed nuisance dust limits
