4. First-aid measures 
Inhalation: In case of excessive inhalation due to leaking batteries remove to fresh air. Obtain medical advice.   
      Skin contact: If exposed to a leaking battery, remove contaminated clothing. Wash exposed areas with plenty of water 
                              and soap. If irritation occurs, consult a physician. 
Eye contact: If a battery is leaking and materials contact eyes, flush immediately with running water for at least 15 
minutes. Consult an ophthalmologist at once. 
Ingestion: Not anticipated due to size of batteries. Choking may occur with the smaller size batteries. If exposed to a 
leaking battery, rinse mouth and surrounding areas with running water for at least 15 minutes. Give plenty 
of water to drink, Do not induce vomiting. Obtain medical advice. 
5. Fire-fighting measures 
Suitable extinguishing media: Carbon dioxide (CO2), foam, dry chemical power. 
Extinguishing media not to be used: Never use a direct water jet.
