6 Presentation objective: To make Emergency responders aware of some of the hazards of vehicles with normal, Hybrid and alternate fuels

7  Awareness Training Only  FYI For your Information  NOT An Approved Course  Information only  You must use your skills learned in NYS Approved classes,  your Dept. training & SOG’s and your common sense  or let somebody else to do it.

8 What is a Hybrid ? More then one power source. Synergistic drive Energy conversion Series and Parallel systems Gasoline Engine and/or Electric Motor(s)

9 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.

10 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.

28 A clear colorless to amber colored, volatile liquid with a petroleum-like odor. Flash point below 0°F. Less dense than water and insoluble in water. Hence floats on water. Vapors heavier than air. Leaked vapors may travel to a source of ignition and then flash back to the source. Ethanol, gas with corn alcohol mixed in.

32 POTASSIUM HYDROXIDE A very Strong Base, 13.5 ph May be found as a gel in cells. Corrosive to metal and tissue. Noncombustible. Apply water if necessary from as far a distance as possible.

33 Causes severe burns of eyes, skin, and mucous membranes. Avoid ANY contact. Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken Modules Wash away any material which may have contacted the body with copious amounts of water or soap and water. If contact with the material anticipated, wear appropriate chemical protective clothing. (© AAR, 1999) Keep material out of water sources and sewers. Apply water spray or mist to knock down vapors. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags. Absorb bulk liquid with fly ash or cement powder. Neutralize with vinegar or other dilute acid. Power Modules on fire or leaking Leave it alone and stay away from them! Super strong Base/ Alkali IT WILL BURN THE CRAP OUT OF YOU AND YOUR GEAR ! and metal & tissue Chemical Burns are Bad Stuff If you must extinguish- Special PPE, Class D, lots and lots of H2O, containment Leaking – Special PPE – and Vinegar or Boric Acid + containment POTASSIUM HYDROXIDE

41 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.

43 Is it off or isn’t it ?

44 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

45 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. Gasoline-Electric Hybrid Vehicle Operation

46 “Ready” light on dash CHECK FOR THEM. IF YOU SEE IT, THE CAR IS “LIVE” AND POTENTIALLY DANGEROUS !!!!

47 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 TAKE OUT THE KEY or KEY FOB !

48 Air bag systems SRS air bags take time to de-power Residual power can last from 90 seconds to 3+ minutes for SRS 5 minutes Bleed Down for HI-Voltage

50 Dress A. Protective clothing PPE (insulated rubber gloves, Face & Eye protection) 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. Necessary items a. Protective clothing, no leather or wool b. Hot Stick c. Saturated boric acid solution or vinegar d. Red litmus paper e. Class “D” extinguisher f. Vinyl tape for insulating cables Turnout Gear with SCBA

51 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
