Hybrid Myths
– Rescue personnel have been electrocuted by cutting into Hybrids
• False… There have been no recorded injuries to firefighters
– If you cut an Orange Wire you will die.
• False – Protected by ground faults
• Remember:
– High Voltage Cables are typically orange in color, but some of the Micro
hybrids with voltages under 60 Volts, may be colored blue.
– The cables run from the high voltage battery pack in the rear of the vehicle to
the engine compartment. The cables are typically routed close to the center
of the vehicle, under the floor of the vehicle. The orange cables may be
visible, or may be covered with a protective plastic cover.
– Inside the orange cable is a ground fault system comprised of a steel braided
cable that automatically shuts down the high voltage if the cable is
compromised in any way.
– The orange cable should be avoided whenever possible, but the high voltage
system is designed to shut down if the cable is accidentally cut.
EXTRICATON TRAINING
– There are no safety devises to protect rescue personnel.
• False – Ground faults throughout the vehicles and relays
– Batteries are always live after an accident.
• Treat as true! – Yet most Hybrid batteries have shear devises that break
from the force of an accident. There is no way to check these, so follow
the 5 safety step protocol.
– After the battery is disconnected I need to wait at least 15 minutes before
proceeding. - False
• Once the battery is disconnected and the key is turned off, all of the high
voltage is restricted to within the high voltage battery case in the vehicle.
The capacitors may take up to a minute to discharge, but they are also
contained within a metal box under the hood.
• Remember: The greatest chance of electrical hazard will occur if you drive
a metal object through the hood or headlight. DON’T DRIVE A
PENETRATING NOZZLE THOUGH THESE AREAS!

• Glass
–Due to respiratory problems, injuries to
firefighters, and patients, and damage
to the structural integrity of cars, it is
now recommended that you leave the
glass in place unless it must be
removed.

• Extrication Strategy and Tactics
– 5 Step Safety Protocol
• Remove hood from hinge side
– Try before you pry
• Check all doors to determine if you can remove the
patient(s) before using cutting and prying tools. If spinal
precautions are needed start removing trim see determine
where you are going to cut.
– Peel and Peek
• Remove all trim before cutting any areas.
– Forget about Low – High – High

Roof Removal – This is the most used extrication technique
nationally. It is the only way to efficiently extricate a patient
with inline stabilization. It should be used, if practical, on all
suspected spinal and head injuries. DON”T CORK SCREW THE
PATIENT !

• Locations for cuts after “peel and peek”
EXTRICATON TRAINING
With regular steel it should take no more than a few seconds to cut each pillar.
EXTRICATON TRAINING
As an alternative to the old process of tunneling, the rear flap
has been developed to speed up the extrication process.

Once the Pt is extricated EMS can decide whether spinal protection
precautions should remain in place, or not, in the safety of the
ambulance. Follow your SOP’s and SOG’s
