Hazards Identification (Section 2)
The cell is not dangerous under normal use conditions. The hazards described apply only in the event of a ruptured or misused battery:
- Skin contact: Electrolyte leakage may cause irritation and soreness.
- Eye contact: Electrolyte vapors may cause eye inflammation. Rinse immediately with water.
- Inhalation: Vapors from a ruptured cell may cause respiratory irritation.
- Ingestion: Electrolyte ingestion can cause tissue damage to the throat.
- Environmental: Electrolyte leakage may contaminate soil and water. Do not allow entry into drains.
- Fire/explosion: Do not dispose of in fire; do not short-circuit.
Handling and Storage (Section 7)
- Do not crush, pierce, directly heat, or solder the battery.
- Do not throw into fire or mix different battery types or new and used batteries.
- Store in a cool, ventilated area away from heat sources, open flames, and corrosive chemicals.
- Keep batteries in original packaging until use to prevent short circuits.
- Keep away from children.
First Aid Measures (Section 4)
- Skin: Remove contaminated clothing; flush with soap and water for at least 15 minutes. Seek medical aid.
- Eyes: Rinse immediately with plenty of water; remove contact lenses before rinsing. Do not rub eyes. Seek medical aid.
- Inhalation: Move to fresh air; administer oxygen or artificial respiration if needed. Seek medical aid.
- Ingestion: Dilute with plenty of water. Seek medical aid immediately. Do not give anything by mouth to an unconscious person.
Fire-Fighting Measures (Section 5)
The cell is non-flammable under normal conditions but may leak combustible electrolyte fumes if overheated. Suitable extinguishing agents include carbon dioxide, dry chemical, and foam. Firefighters must wear full-face filter masks or self-contained breathing apparatus and fire- and toxic-gas-resistant protective clothing and gloves. Extinguish fires from the windward side where possible.
Standards & Compliance
This Material Safety Data Sheet has been prepared in accordance with international standards governing the safety classification, documentation, and transport of lithium ion cells and batteries. The document supports compliance with the following frameworks:
