4. First Aid Measures
Spilled internal cell materials
Inhalation :Make the victim blow his/her nose, gargle. Seek medical
attention if necessary.
Skin contact :Remove contaminated clothes and shoes immediately. Wash
extraneous matter or contact region with soap and plenty of
water immediately.
Eye contact :Do not rub one’s eyes. Immediately flush eyes with water
continuously for at least 15 minutes. Seek medical
attention immediately.
A battery cell and spilled internal cell materials
Ingestion : Make the victim vomit. When it is impossible or the feeling
is not well after vomiting, seek medical attention.
5. Fire-Fighting Measures
Suitable extinguishing media :Plenty of water, carbon dioxide gas, nitrogen gas,
chemical powder fire extinguishing medium and fire
foam.
Specific hazards :Corrosive gas may be emitted during fire.
Specific methods of fire-fighting :When the battery burns with other combustibles
simultaneously, take fire-extinguishing method which
correspond to the combustibles. Extinguish a fire
form the windward as much as possible.
Special protective equipment for firefighters :
Respiratory protection : Respiratory equipment of a gas cylinder style or
protection-against-dust mask
Hand protection :Protective gloves
Eye protection :Goggle or protective glasses designed to protect against liquid
splashes
Skin and body protection :Protective cloth
6. Accidental Release Measures
Spilled internal cell materials, such as electrolyte leaked from a battery cell, are carefully
dealt with according to the followings.
