Hybrid Collision Repair: Safety First

Hybrid Safety Tips

  These technicians have the tires on dollies to avoid charging up the condensers in the inverter by pushing the vehicle with the drive wheels on the ground. This is especially important if towing the vehicle with another vehicle and a towrope.

  Always wear the proper safety gear, including electrical lineman's gloves. Following manufacturer instructions, disable the high-voltage system, test for any stray current with a CAT III certified digital volt ohm meter (DVOM) and avoid or remove the nickel metal hydride (NiMH) battery pack.
  
• 
  Make certain the system has been properly disabled before using welding tools, which can act as electromagnets and send power through the system.

  A technician rolls up the rubber-insulated lineman's gloves to ensure there are no pinholes in them before use.

  Use extra caution if you suspect the collision may have damaged the HV battery pack. Wear rubber gloves and safety goggles, as NiMH batteries contain a potassium hydroxide (KOH), a highly alkaline solution that damages human tissue. Potassium hydroxide also produces hydrogen gas, which is flammable when it contacts certain metals.
  
• 
  Neutralize a battery leak by spraying it with a diluted boric acid solution or vinegar. Use litmus paper to test for alkalinity. When the red paper remains red, the solution has been neutralized.
  
• 
  Talk with first responders in your area to verify they are prepared to assist in an emergency. Water can be used to extinguish a fire, even one involving the NiMH batteries, without the risk of shock or electrocution. However, hydrogen gas may result, as may a host of other poisonous gases in the case of a battery fire. Make sure your fire department knows how to handle a fire involving a hybrid.
