Hazard Statements: Dust may irritate eyes, skin, or respiratory tract on prolonged exposure
Pictograms: None required
Precautionary Statements: Avoid breathing dust, wash hands after handling, wear appropriate protection during bulk handling
Potential Health Effects: Eye or skin contact can cause minor irritation; inhalation of large amounts reflects the nuisance dust character, not chemical toxicity
Chemical Identity: Calcium D-Gluconate Monohydrate
Concentration: Typically over 98% purity
Impurities: Water (crystal), trace compounds from raw extraction
Regulatory Numbers: No relevant harmful impurities at reportable concentrations
Inhalation: Move person to open air, keep comfortable, seek medical help for ongoing irritation or breathing difficulty
Skin Contact: Rinse exposed skin with water, remove contaminated clothing, soap as necessary
Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present, seek medical advice for persistent irritation
Ingestion: Rinse mouth with water, seek professional assessment for large volumes or discomfort
Symptoms and Effects: Irritation, coughing, redness expected in overexposure situations
Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical powder, foam
Specific Hazards: Decomposes on burning to produce carbon oxides and calcium oxides
Advice for Firefighters: Wear full protective clothing, self-contained breathing apparatus, avoid inhalation of combustion products
Unusual Fire Hazards: Product not flammable, but dust buildup may support combustion of other materials
Personal Protection: Use dust mask, goggles, gloves when dealing with spills
Spill Procedures: Sweep up using non-sparking tools, avoid raising dust, collect in sealed containers for use or disposal
Environmental Precautions: Prevent bulk release into drains or waterways, clean thoroughly
Cleaning Methods: Wash spill area with plenty of water after solid collection
Handling: Work in well-ventilated areas, minimize dust creation, use dust extraction systems where available, wash hands after handling
Storage: Store tightly closed in cool, dry, ventilated area, keep away from incompatible chemicals like strong acids, keep containers labeled
Packing Materials: Use moisture-proof, corrosion-resistant packaging to prevent caking or degradation
Exposure Limits: No established limits for calcium gluconate; nuisance dust limits apply (ACGIH TLV: 10 mg/m3 total dust)
Engineering Controls: Provide local exhaust ventilation, protective enclosures for bulk operations
Personal Protective Equipment: Dust respirator (where necessary), safety goggles, lab coat, gloves (nitrile or PVC recommended)
Hygiene Practices: Do not eat, drink, or smoke in work areas; wash hands before breaks; avoid contact with eyes and skin
Appearance: White crystalline or granular powder
Odor: Odorless
pH: 6.0–8.0 (1% solution)
Melting Point: Loses water of crystallization at 100–110°C, decomposes at higher temperature
Boiling Point: Not applicable (decomposes before boiling)
Solubility in Water: 3.5 g/100 mL at 25°C
Density: 1.5–1.7 g/cm³
Vapor Pressure: Negligible
Partition Coefficient: Not relevant for inorganic salt
Other Properties: Stable in normal atmospheric conditions, not volatile or flammable
Chemical Stability: Stable under recommended storage, may absorb moisture from air
Reactive Conditions: Reacts with strong acids to release carbon dioxide, avoid contact with strong oxidizers
Hazardous Decomposition: Carbon oxides, calcium oxides if combusted
Incompatible Materials: Strong acids, strong oxidizing agents can alter properties, leading to byproducts
Acute Toxicity: Oral LD50 (rat): Greater than 2000 mg/kg, reflects low inherent toxicity
Routes of Exposure: Inhalation, ingestion, skin, and eye
Symptoms: Dust may cause coughing, dryness, eye or skin irritation
Chronic Effects: Not classified as carcinogenic, mutagenic, or toxic to reproduction
Other Health Effects: Large ingestion could affect calcium balance in sensitive individuals
Sensitization: No evidence for sensitization or allergenicity
Aquatic Toxicity: Practically non-toxic to aquatic life; low solubility and minimal persistence
Environmental Fate: Not bioaccumulative, degrades to natural substances over time
Mobility: Dissolves slowly in water; unlikely to leach from well-handled spillage
Persistence and Degradability: Biodegradable, mineralizes naturally in the environment
Other Hazards: No known harmful long-term environmental effects
Disposal Methods: Collect excess as dry solid or slurry, dispose as non-hazardous chemical waste in compliance with local regulations
Preventive Actions: Avoid contamination of surface water and soil, follow applicable regional and national waste management requirements
Container Disposal: Thoroughly rinse and manage containers as inert waste unless contaminated
UN Number: Not regulated for transport
Proper Shipping Name: Not classified as dangerous goods by ADR/RID, IATA, IMDG
Packing Group: Not assigned
Special Transport Precautions: Avoid moisture and rough handling to prevent damage or spillage, secure containers to prevent leakage
International Inventories: Listed on TSCA, EINECS/ELINCS, AICS, DSL
SARA Title III: Not subject to reporting requirements
California Proposition 65: Not listed
Labelling: Not required on packaging under current GHS and EU regulations
Workplace Classification: Generally regarded as safe (GRAS) for intended uses in the US and EU; verify local requirements always
