What is a Hybrid ?
• More then one power source.
• Synergistic drive
• Energy conversion
• Series and Parallel systems
• Gasoline Engine and/or
Electric Motor(s)
• Gasoline-electric hybrid means the vehicle
contains a gasoline engine and an electric motor
for power.
• The result of combining these two power sources is
increased fuel economy and reduced emissions.
• The gasoline engine also powers an electric
generator to recharge the battery pack.
• Depending on the driving conditions one or both
sources are used to power the vehicle.
• The illustration demonstrate how the Hybrid
operates in various driving modes.
• On light acceleration at low speeds, the vehicle
is powered by the electric motor. The gasoline
engine is shut off.
• During normal driving the vehicle is powered
mainly by the gasoline engine.
• The gasoline engine and/or the Electric motor
are also used to recharge the battery pack.

ignition and then flash back to the source.

• For transportation it may be stenched.
• Contact with the unconfined liquid can cause
frostbite by evaporative cooling.
• Easily ignited. The vapors are heavier than air
and a flame can flash back to the source of leak
very easily.
• The leak may be either a liquid or vapor leak.
• The vapors can asphyxiate by the displacement
of air.
• Under prolonged exposure to fire or heat the
containers may rupture violently and rocket.
• Easily ignited.
• The vapors are lighter than air and a flame can flash
back to the source of leak very easily.
• 5 percent to 15 percent range
• The leak may be either a liquid or vapor leak.
• The vapors can asphyxiate by the displacement of air.
• Under prolonged exposure to fire or heat the containers
may rupture violently and have devastating results.

•
Hydrogen is a colorless, odorless gas.
It is easily ignited.
The vapors are lighter than air.
It is flammable over a wide range of vapor/air
concentrations.
• Hydrogen is not toxic but is a simple asphyxiant
by the displacement of oxygen in the air.
• Under prolonged exposure to fire or intense heat
the containers may rupture violently and have
catastrophic results.
• General Hydrogen Gas Characteristics
• • Hydrogen gas has a flammable range of between
4% and 74% by volume in air.
• • Hydrogen can ignite with low ignition energy,
especially at higher concentrations. Prevent for
ignition sources.
• • A hydrogen flame produces almost no heat
radiation and tends to transfer a significant amount
of heat to objects and materials impinged on by the
flame, but not surrounding exposures.
• • Burning hydrogen produces a faint blue flame
that is difficult to see, especially in sunlight.
• • It is possible to approach burning hydrogen, not
see the flame and feel no heat.
Is it off or isn’t it ?
Gasoline-Electric Hybrid
Vehicle Operation
•The vehicle starts and becomes operational
by turning the ignition key to start just like any
other typical automobile.
•However, the gasoline engine does not idle
like a typical automobile and will start and
stop automatically.
Gasoline-Electric Hybrid
Vehicle Operation
• It is important to recognize and understand the
READY indicator provided in the instrument
cluster.
• When lit, it informs the driver the vehicle is on
and operational
• Even though the gasoline engine may be off
and the engine compartment is silent.

CHECK FOR THEM. IF YOU SEE IT, THE
CAR IS “LIVE” AND POTENTIALLY
DANGEROUS !!!!
• Put it in park.
• Set the parking brake
• Remove the key and put it on the
dashboard, Cut the power.
• Disconnect the 12 volt negative cables
and the HI-voltage disconnects

Do not touch a bare cable that could be a high voltage cable.
If you need to touch it, wear insulated gloves and
use vinyl tape to insulate the ends of the cable.

operations
• Stabilizing hazards
• Don’t Crib or place airbags under
Hi Voltage harnesses or alternate fuel lines and
energy storage units
• Extricating hazards
• Set all powered options prior to killing power.
• Make sure the car is DEAD and the power is
disconnected and drained (Keys)
• Don’t cut into HV Battery modules, wires, fuel
lines and SRS systems
Summary

•
•
•
•
Use Extreme Caution. Do a good size up.
Check for the READY light, Remove the keys
Chock the wheels, Crib the vehicle as needed
Think High Voltage and fuel systems
Think Safety First with these guys.
Maybe you need to wait for help !
Any questions ?
