Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes; remove contact lenses if present
Skin Contact: Rinse affected skin with water and soap to remove any dust or residue
Inhalation: Move to fresh air, seek medical advice if symptoms persist such as coughing or breathing irritations
Ingestion: Rinse mouth with water and drink small quantities of water; seek attention if large amount is swallowed or symptoms occur
Notes to Physician: Symptomatic treatment only; no specific antidote needed
Suitable Extinguishing Media: Use water spray, foam, dry chemical, carbon dioxide for surrounding fire
Unsuitable Media: Direct high-pressure water streams can spread dust
Special Hazards: Decomposition may release small amounts of carbon oxides; not known to form toxic or flammable gases
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing to guard against particulates
Fire or Explosion Risk: Product not classified as flammable or explosive, but dust in air may pose minimal combustion risk if concentrations are great enough
Personal Precautions: Dust mask, goggles, gloves recommended for cleanup; avoid creating airborne dust
Environmental Precautions: Prevent large quantities from entering waterways or sewers
Spill Cleanup: Sweep up or vacuum up without creating dust, collect into containers for disposal; wash area with water if needed
Methods for Containment: Use barriers or absorbent materials to stop spread, ventilate area
Disposal: Dispose of waste in accordance with local, regional, and national regulations
Safe Handling: Keep containers closed when not in use, minimize dust generation, avoid inhalation or contact with eyes and skin
Storage Conditions: Store in cool, dry, well-ventilated place away from moisture and incompatible chemicals
Incompatible Materials: Strong acids and bases may alter chemical properties, avoid storing near oxidizers
Hygiene Measures: Do not eat, drink, or smoke while handling; wash hands thoroughly after use
Other Handling Cautions: Use only with appropriate ventilation; open containers carefully to avoid dust dispersal
Control Parameters: No exposure limits established for calcium magnesium citrate, but use standard dust limits (OSHA PEL for nuisance dust: 15 mg/m³ total, 5 mg/m³ respirable)
Engineering Controls: Local exhaust ventilation or dust extraction equipment in processing or handling areas
Personal Protective Equipment: Protective goggles to protect eyes, gloves to protect hands, dust mask if airborne particles present
Respiratory Protection: NIOSH-approved particulate respirator if exposure may exceed dust limits
Other Protection: Long-sleeved clothing and lab coat if handling large quantities
Appearance: White to off-white powder or granules
Odor: Odorless

Auto-Ignition Temperature: Not self-heating
Decomposition Temperature: Above 200°C
Viscosity: Not applicable
Chemical Stability: Stable under normal conditions of use and storage
Reactivity: Not reactive with most substances in standard conditions
Hazardous Reactions: Contact with strong acids may release carbon dioxide gas, forming citric acid and corresponding salts
Conditions to Avoid: Exposure to moisture and high humidity
Incompatible Materials: Strong acids and strong bases
Decomposition Products: Carbon dioxide, calcium oxide, magnesium oxide, water vapor, minor organic acids possible with heat
Likely Routes of Exposure: Inhalation, eye contact, skin contact, ingestion
Acute Toxicity: Not expected to be toxic by any route of exposure at typical use levels
Chronic Toxicity: Overexposure through ingestion could result in hypercalcemia or hypermagnesemia, especially in people with renal impairment
Symptoms of Overexposure: Nausea, vomiting, mild digestive irritations, dust may cause transient eye or respiratory irritation
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, OSHA
Mutagenicity: No evidence of genetic toxicity in standard tests
Reproductive Toxicity: No specific data supporting reproductive harm at expected exposure
Ecotoxicity: Low expected aquatic toxicity due to mineral composition, but bulk dumping may affect water hardness and pH
Persistence and Degradability: Rapidly dissociates and neutralizes in aquatic environments
Bioaccumulation Potential: No bioaccumulation expected in aquatic species
Mobility in Soil: Low mobility, strongly bound to soil particles
Other Adverse Effects: Addition to water may temporarily raise mineral content and alter aquatic conditions if released in large amounts
Waste Treatment Methods: Dispose via landfill or approved waste manager, following regional or national legislation
Contaminated Packaging: Completely emptied packages may be recycled or reused; otherwise handle as chemical waste
Precautions: Prevent entry into drains, streams, or natural waters with excessive quantities
