SECTION 2: Hazards Identification
Not applicable

GHS Classification

The chemical compositions are sealed inside the battery. However, if the battery is used improperly,highly alkaline electrolyte and gas will leak from the inside, and if the leaked electrolyte adheres tothe skin or eye, it may cause injury such as blindness, so please strictly observe safety instructions.
Regardless of before or after use, stacking or jumbling of batteries may cause external short circuits
and heating, which may lead to an explosion or fire.

SECTION 4: First Aid Measures
In the case of a leakage (e.g. electrolyte) from the can, take the following measures:
Fumes can cause respiratory irritation. Remove to fresh air and seek medical
Inhalation :treatment immediately.
Skin contact :Immediately rinse with plenty of clean water and seek medical treatment.
Eyes contact : Immediately rinse with plenty of clean water and seek medical treatment.
Ingestion :Rinse mouth with clean water and seek medical treatment immediately.
In the case of ingestion of a battery :May lead to burns. Seek medical assistance promptly.

SECTION 5: Fire Fighting Measures
Fire extinguishing agent
Water, dry sand, and all types of fire extinguishers are effective.
In the case of a fire in the vicinity, avoid high temperatures to prevent an explosion.

SECTION 6: Accidental Release Measures
The battery is sealed to prevent leakage of gas or liquid. Should liquid leak from the battery, wipe it
off with a rag and move the battery to a well-ventilated area. Should the liquid come in contact withthe human body, see Section 4 First Aid Measures.

SECTION 7: Precautions During Handling and Storage
Handling

Keep out of reach of children.
Do not heat or throw into a fire.
Do not deform or disassemble.
Do not short-circuit. Do not connect wires to the terminals, stack batteries, or carryor store them with metal products such as necklaces and hairpins.
Do not connect the terminals in reverse.
Do not charge.
Do not weld or solder directly.
Do not mix old and new batteries or batteries of different types or brands.
Exhausted batteries should be immediately removed from equipment.
Do not swallow the battery. In case of ingestion of a battery, see Section 4 First
Aid Measures.
Do not allow children to replace batteries without adult supervision.

Storage

Store in their original packaging to prevent short circuits.
Keep dry.
Do not store in places of the high temperature, high humidity, or under direct
sunlight.

SECTION 8: Exposure Controls / Personal Protection
The battery is sealed to prevent leakage. There is no need of personal protective equipment on
regular handling and storage. Should a large amount of liquid (electrolyte) leak from the batteries,
wear protective equipment.

SECTION 11: Toxicological Information
There is no toxicity because the chemical compositions are sealed inside the battery.

SECTION 12: Ecological Information
It has been confirmed that there is almost no outflow of metal when exhausted batteries arelandfilled in the ground. Although electrolyte may leak due to deformation or corrosion of the case,heavy metals such as mercury, lead, and cadmium are not used in this battery. There is no otherenvironmental impact information.

SECTION 13: Disposal Considerations
When disposing of this battery, insulate the terminals with tape or other means before disposal toprevent a short circuit due to contact between the battery and metal.
Dispose in accordance with applicable federal, state, and local regulations.

SECTION 14: Transport Information
Our silver oxide battery is not classified dangerous goods by International Air Transport Association(IATA), International Civil Aviation Organization (ICAO), U.S. Department of Transportation (DOT),International Maritime Organization (IMO).
It is not classified as a hazardous material under the current edition of the IATA Dangerous GoodsRegulations (65th edition). It also complies with the special provision A123 and therefore, it can betransported usually by aircraft, ship, vehicle and railway as normal cargo.
Avoid transportations that may heat cargoes to high temperatures, wet cargoes, cause
condensation, or damage cargoes.
