SECTION 2: HAZARD IDENTIFICATION
These products are classified as Articles under REACH and are not subject to the requirements for Information in the Supply Chain(Safety Data Sheets and Labels).
While batteries may release hazardous substances if damaged, this is not an intended release as defined under REACH.
Batteries are not classified as hazardous under the CLP.
The following information is provided to assist in the safe use of our products.
CAUTION: Battery can explode or leak if heated, disassembled, shorted, recharged, exposed to fire or high temperature or inserted incorrectly. Keep in original package until ready touse. Do not carry batteries loose in your pocket or purse. Keep batteries away from children. If swallowed, consult a physician at once. Under certain misuse conditions and by abusively
opening the battery, exposed lithium can react with water or moisture in the air causing potential thermal burns or fire.

SECTION 4: FIRST AID MEASURES
4.1. Description of first aid measures
General- The chemicals and metals in this product are contained in a sealed can. Exposure to the contents will not occur unless the battery leaks, is exposed to high temperatures or ismechanically, physically, or electrically abused.
Inhalation- When exposed to large amounts of steam and mist, move to fresh air.
- Take specific treatment if needed.
Skin contact- Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
- Wash contaminated clothing thoroughly before re-using.
Eye contact- Do not rub your eyes.
- Immediately flush eyes with plenty of water for at least 15 minutes and call a doctor/physician.
Ingestion- Please be advised by doctor whether induction of vomit is demanded or not.
- Rinse your mouth with water immediately.
Note to Physician- Published reports recommend removal from the esophagus be done endoscopically (under direct visualization). Batteries beyond the esophagus need not be retrieved unless there
are signs of injury to the GI tract or a large diameter battery fails to pass the pylorus. If asymptomatic, follow‐up xrays are necessary only to confirm the passage of larger batteries.
Confirmation by stool inspection is preferable under most circumstances. Potential leakage of less than 50 milligrams of dimethoxyethane and propylene carbonate.
Dimethoxyethane rapidly evaporates. Do not give ipecac.

SECTION 5: FIREFIGHTING MEASURES
5.1. Extinguishing media
General Hazard- Cell is not flammable but internal organic material will burn if the cell is incinerated or exposed to high temperatures.
Suitable extinguishing media- Use extinguishing media suitable for the materials that are burning.

5.2. Special hazards arising from the substance or mixture
Hazardous combustion products- Combustion products include, but are not limited to hydrogen fluoride, carbon monoxide and carbon dioxide.

5.3. Advice for firefighters- If possible, remove cell(s) from fire fighting area. If heated above 125°C, cell(s) may explode/vent.

SECTION 6: ACCIDENTAL RELEASE MEASURES
6.1. Accidental release measures- Notify safety personnel of large spills. Irritating vapors and flammable may be released from leaking or ruptured batteries. Eliminate all ignition sources. Evacuate the area andallow the vapors to dissipate.
Clean‐up personnel should wear appropriate protective clothing to avoid eye and skin contact and inhalation of vapors or fumes. Increase ventilation. Carefully collect batteries andplace in an appropriate container for disposal. Remove spilled liquid with absorbent and contain for disposal.

6.2. Personal Precautions, protective equipment and emergency procedures
6.2.1. For non-emergency personnel- Protective equipment: Wear proper protective equipment.
- Emergency procedures: Not applicable- If required, notify relevant authorities according to all applicable regulations.
6.2.2. For emergency responders- Wear proper personal protective apparatus as indicated in Section 8 and avoid skin contact and inhalation.
- Must work against the wind, let the upwind people to evacuate.
- Move container to safe area from the leak area.

6.3. Environmental precautions- Prevent runoff and contact with waterways, drains or sewers.
- If large amounts have been spilled, inform the relevant authorities.
- Avoid dispersal of spilt material and runoff and contact with waterways, drains and sewers. If large spills, advise emergency services.

6.4. Methods and material for containment and cleaning up
6.4.1. For containment- Clear spills immediately- Clean up all spills immediately.
- Control personal contact by using protective equipment.

3/5- Prevent, by any means available, spillage from entering drains or water course.
6.4.2. For cleaning up- Large spill : Stay upwind and keep out of low areas. Dike for later disposal.
- Notify the central and local government if the emission reach the standard threshold.
- Disposal of waste shall be in compliance with the Wastes Control?Act- Appropriate container for disposal of spilled material collected.
6.4.3. Other information- Slippery when spilt.

SECTION 7: HANDLING AND STORAGE
7.1. Precautions for safe handling- Avoid mechanical or electrical abuse. DO NOT short circuit or install incorrectly.

7.3. Specific end use(s)- See Section 1 for information on 1.2 Relevant identified uses.

SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
8.1. Exposure controls/Personal protection
8.1.1. Appropriate engineering controls- Keep away from heat and open flame. Store in a cool dry place.
8.1.2. Individual protection measures, such as personal protective equipment
Hand protection- Wear appropriate glove made out of rubber, neoprene, vinyl coated, PVC.
Eye protection- Wear primary eye protection such as splash resistant safety goggles with a secondary protection face shield.
- Provide an emergency eye wash station and quick drench shower in the immediate work area.
Respiratory Protection- Respiratory protection is ranked in order from minimum to maximum.
- Consider warning properties before use.
Skin protection- Wear appropriate clothing.
Others- It is necessary to wear protective clothes and other protection equipment. Cover your face, head and neck.
- Prior to removing protective garments the employee should undergo decontamination and be required to shower upon removal of the garments and hood.
- Emergency deluge showers and eyewash fountains, supplied with potable water, should be located near, within sight of, and on the same level with locations where direct
exposure is likely.
Thermal hazards- Not available
