Composition / Information on Ingredients
| Component | CAS No. | Formula | Concentration |
|---|---|---|---|
| Calcium Chloride | 10043-52-4 | CaCl2 | 94-97% (w/w) |
Concentrations are nominal; lot-specific values appear on the Certificate of Analysis. Components not contributing to classification are omitted.
First-Aid Measures
- Eyes
- Rinse with plenty of water for at least 15 minutes. Remove contact lenses if present and easy to do. Continue rinsing. Seek medical attention immediately.
- Skin
- Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing. Wash with soap. Get medical attention immediately.
- Inhalation
- Move person to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention immediately.
- Ingestion
- Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention immediately.
- Most Important Symptoms and Effects
- Eye contact causes irritation: redness, pain and tearing.
- Immediate Medical Attention and Special Treatment
- Treat symptomatically. Get medical attention if symptoms develop or persist.
Fire-Fighting Measures
- Suitable Extinguishing Media
- Use water spray, alcohol-resistant foam, dry chemical, or CO2. Use measures appropriate to local circumstances.
- Unsuitable Extinguishing Media
- Do not use a solid water stream as it may scatter and spread fire.
- Specific Hazards Arising from the Chemical
- Containers may rupture when heated.
- Protective Equipment
- Wear self-contained breathing apparatus and full protective clothing.
- Hazardous Combustion Products
- Hydrogen chloride, chlorine and calcium oxides on thermal decomposition.
Accidental Release Measures
- Personal Precautions
- Use PPE as described in Section 8. Ensure adequate ventilation. Evacuate personnel to safe areas.
- Environmental Precautions
- Prevent leakage or spillage from entering drains, sewers, or waterways.
- Containment & Cleanup
- Absorb with inert material. Collect in appropriate waste container. Dispose per applicable regulations.
Handling and Storage
- Safe Handling
- Use with adequate ventilation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Keep container closed when not in use.
- Safe Storage
- Store in a cool, dry, well-ventilated area. Keep away from incompatible materials (see Section 10). Keep containers tightly closed.
- Specific Storage Precautions
- Keep containers tightly closed in a cool, dry, well-ventilated place away from strong acids and oxidizing materials; the material is hygroscopic and moisture sensitive. Non-combustible solid; avoid dust formation.
Exposure Controls / Personal Protection
Occupational Exposure Limits
No established occupational exposure limits.
- Engineering Controls
- Use adequate ventilation. Provide eyewash stations and quick-drench showers accessible to areas of use.
- Eye/Face Protection
- Wear chemical safety goggles or face shield.
- Skin Protection
- Wear chemical-resistant gloves and protective clothing.
- Respiratory Protection
- Use NIOSH-approved respirator if exposure limits are exceeded or irritation occurs.
