3-3.5 Li-ion Battery Damage and Fluid Leaks
The Li-ion battery contains electrolyte solution. To avoid exposure to electrolyte solution
and
serious personal injury, always wear appropriate solvent resistant Personal Protective
Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water and
see a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases,
rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
If electrolyte solution leakage, or damage such as any problem with the Li-ion battery casing are observed,
first responders should attempt to neutralize the battery by applying a large volume of water to the battery
pack while wearing appropriate Personal Protective Equipment (PPE) . The neutralization process helps
stabilize the thermal condition of the battery pack but does not discharge the battery.
Li-ion Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the Li-ion battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
NOTE:
Other fluids in the vehicle (such as washer fluid, brake fluid, coolant, etc.) are the same as
those in a conventional internal combustion vehicle.
3-3.6 Accessing the Occupants 1. Remove windowsa. Perform window removal the same as a normal vehicle.
2. Remove doors a. The doors are removable with hand tools or basic rescue tools such as electrical/hydraulicrescue tools. It may be easier to remove the doors by cutting door hinges.
