Other Components: No hazardous impurities above threshold

First Aid Measures

Eye Contact: Rinse eyes immediately with plenty of water for at least 15 minutes, remove contact lenses if present and easy to do so, seek medical attention
Skin Contact: Remove contaminated clothing, wash skin thoroughly with water and mild soap
Inhalation: Move to fresh air, keep person at rest, seek medical attention if breathing becomes difficult
Ingestion: Rinse mouth, drink water if conscious, never give anything by mouth to an unconscious person, seek medical attention if large quantities are consumed

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Special Hazards: Releases hydrogen chloride fumes at high temperatures
Firefighting Instructions: Firefighters should wear self-contained breathing apparatus
Hazardous Combustion Products: Hydrogen chloride, calcium oxide under extreme heat

Accidental Release Measures

Personal Precautions: Wear suitable protective gear including eye and skin protection
Environmental Precautions: Prevent release to drains, ditches, or water bodies
Methods for Containment: Stop leak if it is safe; dike the area with sand or earth to contain spill
Clean-Up Procedure: Absorb with inert material, shovel into suitable container for disposal, wash area with plenty of water

Handling and Storage

Handling: Avoid contact with skin and eyes, avoid inhaling mist or vapors, use only with adequate ventilation
Storage: Store in tightly closed containers, keep away from moisture and sources of ignition, store in cool, dry, well-ventilated area
Incompatible Materials: Metals such as steel (will corrode), sulfuric acid, zinc, bromine trifluoride

Exposure Controls and Personal Protection

Occupational Exposure Limits: No OSHA PEL or ACGIH TLV established for calcium chloride
Engineering Controls: Local exhaust ventilation recommended to minimize mist
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves (nitrile, rubber), long-sleeved clothing
Respiratory Protection: NIOSH-approved respirator in presence of vapor or mist
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing and wash before reuse

Physical and Chemical Properties

Appearance: Clear to slightly cloudy, colorless to pale yellow liquid
Odor: Odorless
Boiling Point: Approximately 160°C
Melting Point: Below 0°C (due to high concentration and freezing depression)
Specific Gravity: 1.3 to 1.5 (30%–45% solution)
pH: 7–11
Solubility in Water: Completely soluble
Vapor Pressure: Low at room temperature
Evaporation Rate: Negligible
Flash Point: Not applicable
Viscosity: Slightly more viscous than water due to concentration

Stability and Reactivity

Chemical Stability: Stable under normal storage and handling conditions
Reactivity: May react with strong acids to release hydrogen chloride gas
Conditions to Avoid: Excessive heat, moisture uptake during storage
Incompatible Materials: Strong oxidizers, sulfuric acid, metals such as zinc and brass
Hazardous Decomposition Products: Hydrogen chloride, calcium oxide if heated beyond boiling point

Toxicological Information

Acute Toxicity: Oral LD₅₀ (rat) 1000 mg/kg
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Symptoms: Burning of eyes and skin, cough, gastrointestinal disturbances if swallowed
Chronic Effects: Prolonged exposure may cause dermatitis, respiratory sensation aggravation
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Other Data: Not expected to cause reproductive or developmental toxicity

Ecological Information

Aquatic Toxicity: High concentrations can be harmful to aquatic life
Persistence and Degradability: Dissociates into calcium and chloride ions, non-persistent
Bioaccumulation Potential: No bioaccumulation expected
Mobility in Soil: Highly mobile, increases soil salinity
Other Adverse Effects: Spillage may affect surrounding vegetation and freshwater ecosystems, disrupts water balance for amphibians and invertebrates
