• “As a Firefighter for a small City I have been told about a potential hazard to owners of Hybrid cars. As it currently stands in most small cities and towns with Volunteer Fire Departments when a hybrid vehicle is involved in an accident, emergency crews (Firefighters, EMS, Police) are not allowed to touch or put water on a hybrid vehicle until all power has been "disabled" by an authorized person” (I.E. Electrician).

This comment was posted on a popular fire website, on one of the extrication forums. It

clearly shows how much misinformation is floating around.

Following the simple 5-step shut-down

procedures will render the hybrid as safe.

What happens if I accidentally cut through the orange cable?

EXTRICATON TRAINING• 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!

High Strength Steel, increases safety in collisions, and lowers carbon footprint as required by recent laws. It is also part of the required 35 MPG requirement.

• 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

EXTRICATON TRAININGRoof 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.
