CAS Number: 10035-04-8
EC Number: 233-140-8
Concentration: 98-100%
Impurities: Trace amounts of sodium chloride, magnesium chloride, water-insoluble matter possible below 2%
Ingredient List: Major ingredient is calcium chloride, minor impurities only; no additives or stabilizers listed
Inhalation: Move affected person to fresh air; if breathing becomes difficult, seek medical attention; coughing or discomfort may occur
Skin Contact: Remove affected clothing; rinse skin with plenty of water; seek medical advice if irritation persists
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, remove contact lenses if present and easy to do, seek medical attention for persistent redness or discomfort
Ingestion: Rinse mouth; do not induce vomiting; drink water if the person is conscious; seek medical attention for larger quantities
Symptoms: Irritation, redness, coughing, shortness of breath; high intake may cause stomach upset
Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide; product itself does not burn
Unsuitable Extinguishing Media: None known specific to the product
Hazardous Combustion Products: Hydrogen chloride, calcium oxide may be released at high temperatures
Special Fire-Fighting Procedures: Firefighters use self-contained breathing apparatus if dust forms; product may react vigorously with some metals at elevated temperature
Protective Equipment: Standard protective clothing, NIOSH-approved respiratory protection for large fires
Personal Precautions: Restrict access to area; avoid inhalation of dust; ensure adequate ventilation; use personal protective equipment
Environmental Precautions: Prevent runoff into sewers and surface water; consider potential salinity impact for large spills
Containment Methods: Sweep or vacuum up material without generating dust; collect in containers for proper disposal
Cleaning Methods: Wash spill area with plenty of water after cleanup; residue may make floors slippery
Safe Handling: Avoid dust generation; use with adequate ventilation; wear suitable protective equipment; keep away from incompatible substances (strong acids, metals like zinc); wash hands after use
Safe Storage: Store in airtight containers; keep dry; avoid moisture uptake; maintain clear labeling; keep away from food and drink
Storage Temperature: Ambient, away from sources of heat and ignition
Packaging Materials: High-density polyethylene, polypropylene or plain steel (avoid prolonged contact with moisture)
Exposure Limits: OSHA and ACGIH have no specific exposure limit for calcium chloride; total dust as nuisance: 15 mg/m³ (OSHA PEL), 10 mg/m³ (ACGIH TLV)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep dust levels below recommended limit
Personal Protective Equipment: Safety goggles to protect eyes; gloves (PVC, rubber, nitrile); lightweight long sleeves and pants; dust mask or respirator (NIOSH-approved N95 or higher) for dusty operations
Hygienic Practices: Wash hands and face before breaks and after work; do not eat, drink, or smoke in work areas
Environmental Controls: Prevent dust release outside work area; utilize closed systems where feasible
Appearance: White, crystalline, granular, or powder form
Odor: Odorless
pH (aq. solution): 8–10 (5% in water)
Melting Point: 175 °C (decomposes)
Boiling Point: Loses water at >160 °C
Flash Point: Not flammable
Solubility: Soluble in water (740 g/L at 20 °C), slightly soluble in alcohol
Density: 1.85–1.87 g/cm³ (bulk)
Vapor Pressure: Not volatile
Partition Coefficient (n-octanol/water): Not applicable
Viscosity: Not applicable for solid
Evaporation Rate: Not applicable
Chemical Stability: Stable under recommended storage conditions
Reactivity: Hygroscopic; absorbs moisture from air; may cause mild corrosion on metals upon contact with water
Conditions to Avoid: Moisture, high temperatures, contact with incompatible substances
Incompatible Materials: Strong acids, strong oxidizing agents, metals like zinc and sodium, methyl vinyl ether
Hazardous Decomposition Products: Hydrogen chloride, calcium oxide under extreme heat or in reaction with acids
Polymerization: Will not occur
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): ~1000 mg/kg; skin and eye irritation documented
Skin Irritation: Causes redness and dryness upon prolonged contact
Eye Irritation: Severe irritation, redness, tearing
Respiratory Effects: Dust may irritate mucous membranes, sneezing, coughing
Chronic Effects: Prolonged exposure can aggravate respiratory illness; no carcinogenic effects found in studies
Other Effects: Possible upset stomach, vomiting, diarrhea with large oral exposure
Ecotoxicity: Large spills may raise soil or water salinity and harm sensitive vegetation or aquatic organisms
Persistence and Degradability: Dissolves in water; calcium and chloride ions occur naturally in environment
Bioaccumulation: Not expected; both ions integrate into natural biogeochemical cycles
Mobility in Soil: High water solubility leads to leaching in soil
Other Adverse Effects: No significant ozone depletion or global warming effect documented
Disposal Methods: Disposal in accordance with local, regional, national, and international regulations; never discharge directly to water systems
Contaminated Packaging: Rinse with water, recycle or dispose of as solid waste
