2．Hazard identification
The important hazards and adverse effectsof the chemical productNo information available

Chemical product- specific hazards

No information available

HazardCoin manganese dioxide lithium batteries contain flammablematerials such as organic solvent and metallic lithium.
If battery was disposed in fire, or battery temperature exceeded
100℃, explosion or ignition of the battery may be caused.
When short-circuit is caused by jumbling the batteries,
explosion or ignition may be caused due to heat generation.

Toxicity

When battery is burned, generated vapor may cause eyes, skinand respiratory irritation.

4．First aid measures

Swallowing

Ingestion of a battery can be harmful.
Contents of an opened battery can cause serious chemical burns of mouth, esophagus and gastrointestinal
tract. In either case, do not induce vomiting nor give food or drink.
Seek medical attention immediately.

Skin Contact

Contents of an opened battery can cause skin irritation.
Wash skin with soap and water.
If inflammation was caused on the skin, seek the medical attention.

Eye Contact

Contents of an opened battery can cause eye irritation.
Immediately flush eyes thoroughly with water for several minutes.
Seek medical attention.

Inhalation

Contents of an opened battery can cause respiratory irritation.
Provide fresh air and call a doctor.

5．Fire fighting measures

Extinguishing Media

Powder, Carbon dioxide and Dry sand.
Metallic Lithium contained in a battery reacts with water strongly, as a result,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
serious health hazard.
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
Since improper battery handling may cause leakage, overheating or explosion of the battery, thefollowing precautions shall be observed.

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

10．Stability and reactivity
Stability
Condition to avoid: Stable under normal conditions of use.
: 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 seldomfound. 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.
