## 4 `．` First aid measures 

|．First aid measures||
|---|---|
|Swallowing|Ingestion of a battery can be harmful.<br>Contents of an opened battery can cause serious chemical burns of mouth, esophagus and gastrointestinal<br>tract. In either case, do not induce vomiting nor give food or drink.<br>Seek medical attention immediately.|
|Skin Contact|Contents of an opened battery can cause skin irritation.<br>Wash skin with soap and water.<br>If inflammation was caused on the skin, seek the medical attention.|
|Eye Contact|Contents of an opened battery can cause eye irritation.<br>Immediately flush eyes thoroughly with water for several minutes.<br>Seek medical attention.|
|Inhalation|Contents of an opened battery can cause respiratory irritation.<br>Provide fresh air and call a doctor.|



## 5 `．` Fire fighting measures 

|Extinguishing Media|Powder, Carbon dioxide and Dry sand.<br>Metallic Lithium contained in a battery reacts with water strongly, as a result,<br>generates hydrogen gas. Extinguishing by water may cause explosion.|
|---|---|



## 6 `．` Accidental release measures  (In the case that electrolyte is leaked from battery.) 

|Personal precautions|Temporary inhalation of odor and attaching of electrolyte to skin does not cause<br>serious health hazard.<br>Be sure the ventilation and washing out of electrolyte quickly.|
|---|---|
|Environmental precautions|Wipe off with dry cloth and keep away from fire.|

## 7 `．` Precautions for safe handling and use 

|Handling|Since improper battery handling may cause leakage, overheating or explosion of the battery, the<br>following precautions shall be observed.<br>(1)<br>Keep batteries away from children.<br>Swallowing a battery can cause chemical burn or penetration of the mucous membrane tissue,<br>in the worst case, may result in death.<br>If infant happens to swallow a battery, seek medical attention immediately to take it out.<br>(2) Do not short.<br>(3) Insert batteries with positive (+) and negative (-) terminals correctly oriented.<br>(4) Do not mix different type batteries or mix new and old ones together.<br>(5) Do not directly heat, solder or throw into fire.<br>(6) Do not modify, deform or disassemble the battery.<br>(7) Do not have children replace batteries unsupervised by adults.<br>(8) In case of swallowed battery, seek medical attention immediately.<br>(9) This battery is not designed for recharging. To do so can cause leakage or explosion.|
|---|---|
|Storage|Store in a cool, well-ventilated area.<br>Do not store batteries at high-temperatures or high-humidity.<br>Proper storage temperature is +5℃~+35℃.<br>It is preferable not to exceed +35℃.<br>Avoid extremely higher or lower humidity (85% or more, 45% or less).<br>Avoid exposure to sunlight to prevent performance deterioration, swelling or leakage.<br>Elevated temperature can result in shortened battery life.<br>Since short circuit can cause burn hazard and leak or explode hazard, do not batteries jumbled in<br>containers. Avoid to contact water, metallic chain or metallic chip which may result in short-circuit.|

## 10 `．` Stability and reactivity 

Stability : Stable under normal conditions of use. Condition to avoid : See Section 7. 

## 11 `．` Toxicological information 

Under normal conditions of use, there is no risk to life and health, because ingredients of battery is hermetical sealed with metal case. 

## 12 `．` Ecological information 

When exhausted battery is buried in the ground, it is confirmed that outflow of metal contained in the battery has been seldom found. But we have no ecological information. 

## 13 `．` Disposal considerations 

When battery is disposed, isolate positive (+) and negative (-) terminals of the battery to avoid those terminals from touching each other. Batteries may be short-circuited when piled up or mixed with the other batteries in disorder. Dispose in accordance with applicable federal, state and local regulations.
