  1. Module IV: Initial Response: Identify, Immobilize and Disable 4-1

  2. Module IV Objectives Terminal Objective Demonstrate knowledge of initial response procedures for an incident involving P/HEVs and EVs, including how to Identify, Immobilize and Disable the vehicles. Enabling Objectives • Identify size up procedures and scene hazards of an incident involving a P/HEV and EV. • Identify P/HEVs and EVs using formal and informal methods and using the Emergency Field Guide. • Identify Immobilization procedures. • Identify vehicle Disabling procedures. 4-2

  3. ENSURE A SAFE WORK ENVIRONMENT FOR RESPONSE PERSONNEL Use proper PPE 4-3

  4. Scene Size-Up Survey scene for hazards (Scene 360). Identify types of vehicles involved. Determine course of action. 4-4

  5. Common Hazards at Any Incident Scene • Traffic. • Downed power lines. • Fuel Spills or other • HAZMAT. • Environmental Hazards. • Fire. • Unstable vehicles. 4-5

  6. Initial Response Actions 4-6

  7. Electric Vehicle Emergency Field Guide (EFG) 4-7

  8. Emergency Field Guide (EFG) • Consolidated Quick • Reference Guide. • Simple, easy-to-use • format. • Identification • Shutdown • Danger areas • System diagrams • Suppression • Submersion 4-8

  9. Initial Response Actions 4-9

  10. Activity 4.1 Part 2 SIZE UP: IDENTIFICATION It is often difficult to identify P/HEVs and EVs from a distance. Assume all vehicles are P/HEV or EV until positive identification is made. Approach from the sides if possible. 4-10

  11. Why is it important to be able to distinguish a P/HEV or EV from a conventional car or truck? 4-11

  12. Which Toyota Highlander is the hybrid? 4-12

  13. Identification Methods • Formal Identification • Informal Identification • Telematics • NFPA Emergency Field Guide 4-13

  14. Formal Identification • Badging • Engine Emblems • Instrument Cluster 4-14

  15. Formal Identification Badging Usually on front fenders, doors, or rear. May become hidden or dislodged. 4-15

  16. Formal Identification Badging often involves manufacturer trade names. 4-16

  17. Formal Identification Badging • Some EVs have badging that indicates they are “Electric” or “Zero Emission” vehicles. • Some model names are specific and are only made as P/HEVs or EVs. 4-17

  18. Formal Identification Engine Compartment Emblems Manufacturers use different terms • Hybrid • Hybrid Synergy • Drive • IMA (Integrated • Motor Assist) 4-18

  19. Formal Identification Instrument Cluster • Hybrid logo • IMA logo • Integrated Motor Assist (Honda) • May not be visible when vehicle is shut down. 4-19

  20. Informal Identification Other clues that indicate a P/HEV or EV. • High Voltage • Labels • Instrument • Panel • Electrical • Cables • Battery Vents 4-20

  21. Informal Identification High Voltage Warning Labels • High voltage warning labels under hood and on high voltage components and cabling. • Some labels may show the location of the 12 VDC and HV battery. 4-21

  22. Informal Identification Instrument Panel Items • Charge • Assist • Indicators • Battery • Status • Indicator • Ready • Indicator READY 4-22

  23. Electrical Cables Informal Identification High Voltage Cables • Orange (High), • blue or yellow (intermediate). • Found under hood and on underside of vehicle. • Usually not placed • in typical cut points. 4-23

  24. Informal Identification Electrical Cables High Voltage Cable • No requirement that HV cable is visible. • Black shrouding around cables on many models. • Plastic paneling on underside on some models, covering cable. • More visible on older models. 4-24

  25. Informal Identification Battery Vents • Vents keep high • voltage battery • from overheating. • Located in general vicinity of the battery. • Often look like HVAC vents or speakers. • Not all vehicles • have visible • vents. 4-25

  26. Identification • Use all • Information • available. • Take the • time to check. • If no badging • visible, look • for additional • clues. 4-26

  27. Telematics Electronic vehicle safety and security systems which monitor vehicle status Examples: OnStar (GM) Blue Link (Hyundai) BMW Assist (BMW) 4-27

  28. Transmitting System Telematics Vehicle Crash Response Agency • During emergency, information is transmitted, and forwarded to nearest response agencies. • Includes if the vehicle is a P/HEV or EV. • Use of telematics is increasing. 4-28

  29. Initial Response Actions 4-29

  30. Immobilize the Vehicle • Chock the wheels. • Place vehicle in park. • Engage the emergency brake. 4-30

  31. Useful Information • Joystick Shifters • return to the • same position • regardless of gear. • Push Button Park • on some models • actuate electrical • mechanism. • Electronic parking brakes will not engage • after battery power is cut. 4-31

  32. Initial Response Actions 4-32

  33. Disable the Vehicle Primary Method • Shut Off Vehicle Ignition • Disconnect 12 VDC Battery 4-33

  34. Video Disabling the High Voltage System

  35. Push button and Proximity Key Systems • Secure the driver’s • key and locate any • additional keys. • Move the keys at least • 16 feet away. • If you cannot secure • key, continue with • appropriate shutdown • procedure. 4-35

  36. Disable the Vehicle Secondary Method (For some models) • Disconnect 12 VDC Battery. • Pull the high voltage system control • fuse. 4-36

  37. Disable the Vehicle Secondary Method IMPORTANT SAFETY NOTE: • Both steps (cut 12 VDC battery and pull • HV fuse) are critical for disabling both the • HV system and the airbags. • If the vehicle ignition was not shut off, the • DC-DC converter can still provide 12 VDC • power to the HV Battery Relays. • Pulling the HV System Fuse interrupts • current from both 12 VDC power sources • to the HV battery, opening the HV relays, • and shutting down the HV system. 4-37

  38. Disable the Vehicle Reference NFPA EFG or Manufacturer’s ERG for the specific vehicle to determine…. • Which fuse to pull (not • all models recommend • this method). • Secondary disabling • procedures for that • model. 4-38

  39. High Voltage System Drain-Down • Some models have • capacitors that can • retain HV energy for • up to 10 minutes. • After system is • shut down, the high • voltage battery still • retains its charge. • Always assume the • system is still • energized. 4-39

  40. High Voltage Batteries Service Disconnects • Recommendations for • use and required • safety equipment vary • by manufacturer. • Consult appropriate • ERG before using • service disconnect. • Located on the • battery. • Cuts off the battery • from the high voltage • system.

  41. Activity 4.1 IDENTIFICATION DRILL You will be shown a series of slides, each with a picture of a vehicle or a component of a vehicle. You will be given a few moments to determine if … 1. The vehicle IS a P/HEV or EV, or 2. The vehicle IS NOT a P/HEV or EV, or 3. Cannot tell. The information is not sufficient to determine if a P/HEV or EV is involved, or not. 4-41
