Inhalation: Move person to fresh air; provide oxygen if breathing becomes difficult; seek medical attention if symptoms persist
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing; consult a doctor if irritation develops
Eye Contact: Rinse immediately with clean water for at least 15 minutes, holding eyelids open; seek medical help if redness or discomfort does not subside
Ingestion: Rinse mouth with water; do not induce vomiting; offer water to drink; call a physician if symptoms appear
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide
Specific Hazards: May form carbon oxides, calcium oxides, and nitrogen oxides on thermal decomposition
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective suit
Special Procedures: Cool exposed containers with water spray to reduce pressure build-up; avoid inhalation of combustion products
Personal Precautions: Wear appropriate personal protection including gloves, goggles, and a dust mask; ventilate area
Environmental Precautions: Prevent further leakage or spillage if safe to do so; avoid discharge into drains or surface water
Cleanup Methods: Carefully scoop or sweep up without generating dust; place in suitable containers for proper disposal; flush residual area with water while avoiding runoff into the environment
Handling: Minimize dust generation; use in a well-ventilated area; avoid inhalation and contact with skin or eyes; ensure proper training for those handling large amounts
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place; keep away from moisture, strong acids, and incompatible materials; avoid temperature extremes to protect stability
Occupational Exposure Limits: No specific limits set for DL-Calcium Pantothenate
Engineering Controls: Use local exhaust ventilation or fume hood to minimize exposure
Personal Protective Equipment: Wear protective gloves (nitrile recommended), safety goggles, and a lab coat; use a dust respirator if dust becomes airborne; practice good hygiene by washing hands after handling
Environmental Controls: Ensure proper containment to avoid releases to the workplace or environment
Appearance: White, odorless, crystalline powder
Melting Point: Begins to decompose above 190°C
Boiling Point: Not applicable (decomposes before boiling)
