Please refer to the full document for details.

The content of this safety guide may be periodically updated or revised as the scope of product environmental regulations expands.

1. Electrical Hazards

  • LG Energy Solution ESS products are safe under normal conditions. However, damaged batteries may pose high-voltage and electric shock risks.
    Exercise caution if the enclosure, rack, pack, or safety circuit is damaged.
  • Do not immerse the battery pack in liquid, puncture, break, short-circuit, incinerate, or forcibly discharge it. These actions can result in Internal or external short circuits, leading to severe overheating.

2. Mechanical Damage Risks

  • Store battery packs in their original packaging to prevent mechanical damage.
  • Dropping battery products can cause severe damage. Conduct a visual inspection after a drop, and discontinue use if damage is suspected.
    Damaged batteries should be stored separately and transported in an insulated condition.

3. High-Temperature Exposure Risk

  • ESS batteries operate normally at 0–40°C and <85% non-condensing humidity.
  • At 80°C or higher, electrolyte leakage may occur.
  • Exposure to temperatures above 150°C for several minutes can cause thermal runaway and fire risk.

4. Electrolyte Leakage Risk

  • Mechanical damage may cause electrolyte leakage from the cell. Leaked electrolyte contains volatile organic compounds and fluorine compounds,
    which can irritate skin and respiratory system.
  • In the event of a leak, immediately ventilate the area and handle it while wearing appropriate personal protective equipment.

5. Emission Gas Risk

  • ESS batteries do not emit gases during normal operation. However, severe thermal runaway or abnormal heating may cause gas emissions, which can be flammable and toxic. Avoid exposure and immediately notify local fire services and emergency responders.

6. Fire Response

  • If a high-temperature event occurs in the battery enclosure, do not open the enclosure door, as it may explode. Stay at least 10 meters away from the enclosure.
