Signal Word: Warning
Hazard Statements: Causes serious eye irritation, causes skin irritation, may cause respiratory irritation if inhaled as dust.
Pictograms: Exclamation mark
Precautionary Statements: Avoid breathing dust, wear eye/face protection, wash exposed skin thoroughly after handling, use only outdoors or in well-ventilated area
Chemical: Calcium Chloride Anhydrous
CAS Number: 10043-52-4
EC Number: 233-140-8
Purity: >97%
Impurities: May contain trace amounts of magnesium chloride, sodium chloride, potassium chloride (generally <3%)
Inhalation: Move exposed person to fresh air, keep at rest in a comfortable position, seek medical attention if symptoms persist
Ingestion: Rinse mouth with water without inducing vomiting, give water to dilute, seek immediate medical attention if discomfort or large amounts swallowed
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical advice for persistent irritation
Eye Contact: Rinse cautiosuly with water for several minutes, remove contact lenses if present and easy to do, continue rinsing and seek medical attention for pain or vision changes
Flammability: Product does not burn
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Hazardous Combustion Products: Hydrogen chloride gas may be generated with high heat or contact with some metals in moisture
Firefighter Protection: Wear self-contained breathing apparatus and full protective clothing
Special Procedures: Use water spray to cool exposed containers, prevent spillage from entering drains or watercourses
Personal Precautions: Evacuate area if large dust release, wear protective equipment (gloves/eye protection), avoid contact with skin, eyes, clothing
Environmental Precautions: Prevent entry into watercourses, soil, drains; not classified as hazardous to aquatic environment but large quantities may affect salinity
Clean-up Methods: Sweep up or vacuum material and place in suitable container for disposal, wash contaminated area with plenty of water after material collection, ventilate enclosed spaces
Handling: Use adequate ventilation, handle with gloves and eye protection, minimize dust generation and accumulation, avoid eating or drinking while handling product
Storage: Keep container tightly closed, store in cool, dry, well-ventilated place away from moisture and incompatible substances such as strong acids, water-reactive materials
Storage Incompatibilities: Avoid contact with acids and metals such as zinc or aluminium in presence of moisture, as corrosive hydrogen chloride gas may be released
Exposure Limits: No occupational exposure limits have been established for calcium chloride
Engineering Controls: Use local exhaust ventilation or process enclosure to reduce airborne dust levels
Personal Protection:
Appearance: White, odorless, crystalline solid
Odor: No significant odor
pH (10% solution): 8 to 10
Melting Point: Approx. 772°C (1422°F)
Boiling Point: Sublimes at 1600°C (2912°F)
Relative Density: 2.15-2.36 g/cm³
Solubility in Water: Highly soluble (740 g/L at 20°C)
Hygroscopicity: Readily absorbs moisture from air
Vapor Pressure: Not applicable (solid under ambient conditions)
Flash Point: Not combustible
Odor Threshold: Not applicable
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts exothermically with water, strong acids, and some metals (especially with moisture)
Conditions to Avoid: Exposure to moisture/humidity, incompatible substances
Incompatible Materials: Acids, zinc, sodium, bromine trifluoride, methyl vinyl ether, and water-reactive substances
Hazardous Decomposition Products: May produce hydrogen chloride gas in contact with acids or metals in presence of water
Polymerization: Will not occur
Probable Routes of Exposure: Inhalation of dust, skin and eye contact, ingestion
Acute Toxicity: LD50 (rat, oral) 1000 mg/kg to 2100 mg/kg (varies by source); may cause gastrointestinal irritation
Skin: May cause moderate irritation and dryness, especially with repeated or prolonged exposure
Eyes: Causes eye irritation, possible corneal injury from solid contact
Respiratory: Dust may cause coughing, sore throat, respiratory irritation
Chronic Effects: No evidence of carcinogenic, mutagenic, or reproductive hazards in humans
Medical Conditions Aggravated: Individuals with pre-existing skin, eye, or respiratory disorders may be more susceptible to the effects
Ecotoxicity: Large spills may cause localized impacts due to increased salinity of soil or water, can be harmful to aquatic life and vegetation in high concentrations
Persistence and Degradability: Inorganic, not subject to biological degradation, persists in environment as calcium and chloride ions
Bioaccumulation: Not likely, as it dissociates in water to ions that are essential nutrients at low concentrations
Mobility in Soil: Highly soluble, will leach readily through soil with water migration
Other Adverse Effects: Elevated chloride levels can disrupt local plant and aquatic life
Disposal Methods: Dispose of in accordance with local, regional, and national regulations; product is not considered hazardous waste but large volumes should be minimized where possible
Uncontaminated Product: May be used for original purpose if uncontaminated, otherwise dissolve in water and dilute before sewering if regulations permit
Packaging: Contaminated packaging should be disposed of as non-hazardous waste, ensuring no large residues remain
Precautions: Avoid release to environment, do not mix with acids or reactive substances during disposal
UN Number: Not regulated as a hazardous material by road, air, or sea
