Emergency Procedures: Ensure area is cleared of non-essential personnel; clean up promptly using best industrial hygiene practices
Precautions for Safe Handling: Handle using standard industrial hygiene practices; wash hands before eating, drinking, or smoking after handling bulk quantities
Technical Measures: Avoid creating or inhaling dust; use only in well-ventilated areas; keep containers sealed when not in use
Storage Conditions: Store in a cool, dry place in tightly closed containers; avoid exposure to moisture and direct sunlight
Incompatibilities: Avoid strong acids (which may decompose salt, releasing CO2), strong oxidizers
Other Guidance: Label storage areas clearly; stack product to avoid spills
Exposure Limits: No established OSHA or ACGIH limits for calcium citrate
Engineering Controls: Use general or local exhaust ventilation to control dust concentrations; workplace air monitoring as needed
Personal Protective Equipment: Dust mask or respirator, safety glasses, gloves for extended contact
Hygiene Measures: Do not eat, drink, or smoke during handling; wash hands and face after work
