GHS Classification: Eye irritation (Category 2A), Skin irritation (Category 2)
Hazard Statements: Causes serious eye irritation, may cause skin irritation, can aggravate pre-existing lung conditions if inhaled as dust
Pictogram: Exclamation mark (irritant)
Signal Word: Warning
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Target Organs: Respiratory tract, eyes, skin
Aggravated Conditions: Existing dermatitis, asthma or other respiratory issues
Substance: Single substance
Component: Calcium Chloride
Concentration: 94% to 100% (anhydrous form; lower for dihydrate and hexahydrate forms)
Impurities: May include trace magnesium chloride, sodium chloride, and calcium hydroxide from natural sources
Eye Contact: Flush eyes several minutes with water, remove contact lenses, seek medical help if irritation continues
Skin Contact: Wash skin thoroughly with soap and water, remove contaminated clothing, get medical attention for persistent redness or discomfort
Inhalation: Move person to fresh air, provide oxygen if breathing is difficult, get medical attention for prolonged symptoms
Ingestion: Rinse mouth, give plenty of water, avoid inducing vomiting, get medical help for large ingestions or symptoms such as nausea or vomiting
Most Important Symptoms: Redness, watering, pain in eyes and skin, throat irritation
Note to Physicians: Treat supportively, no specific antidote
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Media: None known for product, but avoid releasing water directly onto heated product
Hazardous Combustion Products: Emits hydrogen chloride gas if exposed to acid
Protective Equipment for Firefighters: Full protective gear, self-contained breathing apparatus
Fire/Explosion Hazards: Not flammable, but reacts with metals to produce hydrogen gas
Advice: Prevent runoff from fire control or dilution from entering waterways
Personal Protection: Use gloves, goggles, dust mask for dry material
Spill Response: Sweep up spilled powder or granules, avoid raising dust, collect in containers for reuse or disposal
Cleanup: Wash affected area with plenty of water, prevent spillage into sewers/drains
Environmental Precautions: Minimize contamination of soil and water, excessive concentration can harm aquatic life
Notification: Follow local and national guidelines for reporting significant spills
Handling Precautions: Minimize dust generation, wear appropriate protection, wash hands after use, avoid breathing dust
Storage Requirements: Store in tightly closed containers, keep in dry air-tight area, protect from moisture uptake
Temperature Limits: Stable at ambient temperatures, deliquescent (absorbs water readily from air)
Incompatible Materials: Avoid storing near acids, zinc, or aluminum
Special Considerations: Keep away from children, label containers appropriately, prevent runoff during handling
Exposure Limits: No occupational exposure limits set for calcium chloride, but limit total nuisance dust (ACGIH TLV for particulates not otherwise classified: 10 mg/m3 total, 3 mg/m3 respirable fraction)
Engineering Controls: Local exhaust ventilation for dust-producing operations
Personal Protection: Safety glasses for eye contact, gloves for skin protection, dust mask or respirator for airborne particles
Hygiene: Wash exposed skin before eating or drinking, launder contaminated clothing
Environmental Exposure: Use containment to prevent large spills affecting soil or water
Appearance: White hygroscopic flakes, granules or powder
Odor: Odorless
pH: 8 to 10 (10% solution)
Melting Point: 772°C
Boiling Point: Decomposes above 1600°C
Solubility: Freely soluble in water, releases heat when dissolving; slightly soluble in alcohol
Density: 2.15 g/cm3 (anhydrous)
Vapor Pressure: Negligible
Evaporation Rate: Not applicable
Partition Coefficient: Not expected to bioaccumulate
Chemical Stability: Stable under normal storage and use
Reactivity: Exothermic reaction with water
Hazardous Reactions: Releases heat with water, generates hydrogen chloride with acids, reacts with metals (e.g. zinc or aluminum) in presence of moisture to liberate hydrogen gas
Conditions to Avoid: Exposure to moisture and incompatible materials
Incompatible Materials: Strong acids, borax, reactive metals
Decomposition Products: Calcium oxide, hydrogen chloride under extreme conditions
Acute Toxicity: Oral LD50 (rat): 1000 mg/kg to 2301 mg/kg depending on hydration form
Skin Contact: Prolonged or repeated exposure may cause drying and irritation
Eye Contact: Causes redness, watering, pain, possible conjunctivitis
Inhalation: Irritates respiratory tract if exposed to dust
Ingestion: Large quantities may cause nausea, vomiting, abdominal discomfort
Chronic Effects: No evidence of chronic toxicity reported at expected levels
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, OSHA
Mutagenicity: No recognized mutagenic potential
Reproductive Effects: Not associated with reproductive risks
Ecotoxicity: High concentrations impact aquatic organisms; can raise salinity of freshwater systems and harm vegetation
Persistence and Degradability: Dissolved calcium and chloride ions do not persist in the environment
Mobility: Soluble in water, can seep into soil and water bodies
Bioaccumulation Potential: Not known to bioaccumulate in organisms
Aquatic Toxicity (LC50 fish): 10670 mg/L (96 hours, rainbow trout)
Soil Mobility: High; may alter soil chemistry and affect plant growth
Other: Prolonged or excessive application to soil may inhibit plant growth by increasing soil salinity
Waste Disposal: Dispose of in accordance with local, regional, and national regulations
Product Waste: Small amounts may be diluted and flushed to sewer with plenty of water if regulations permit; larger amounts should be taken to a hazardous waste facility
Container Disposal: Triple rinse and offer for recycling or disposal according to regulations
Precautions: Prevent entry into natural waterways, avoid large scale land disposal that could affect vegetation
