High-Voltage Battery Damage and Fluid Leaks

The HV Battery assembly is enclosed in a sturdy metal case that is rigidly mounted to structural
components of the vehicle. This construction helps prevent damage to the HV Battery assembly
even in severe crashes. This section provides emergency responders with information regarding
how to mitigate the severity of a damaged HV Battery assembly or gel electrolyte spill, however
unlikely that might be.
• Cease all smoke, spark, flame activity around the vehicle.
• Electrolyte solution is a skin irritant.
• Do not touch or step on the spilled electrolyte.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use oil, sand, or a dry cloth
to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
Irritant Substance Risk!
• Internal components of HV Batteries are irritants and sensitizers.
• To avoid contact with these irritants and sensitizers wear positive pressure self- contained
breathing apparatus (SCBA) and other personal protective equipment (PPE) designed for use
with these types of hazards.
Failure to wear proper SCBA and PPE can result in serious injury or death
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water for 15
minutes.
• Electrolyte solution is a skin irritant. Therefore, if there is contact with skin, wash off with soap.
• 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 a well ventilated location for fresh air and wash mouth with water. See a doctor
immediately.
