Alternative Fuel Vehicles (AFV) Flashcards
Name the 6 types of AFV
High voltage fuel cells (batteries) Compressed gas (CNG) Liquefied gas (LPG/LNG) Biofuels Hydrogen fuel cells Hybrid/ dual fuel
How to identify AFV type
Diver/passengers Vehicle markings/ badges MDT/ control Fuel cap Orange cabling
Be aware some cars may be modified and not have correct markings
Name the 6 hazards of compressed / liquefied gases
Extremely cold Explosion Highly glammable atmosphere Fire, heat, smoke Irreparable atmosphere Pressurised system
What to do with compressed/ liquefied gas vehicle on fire
25m cordon Cooling tank asap Do jot extinguish flame jet of pressure relief Safety jet Defensive fire fighting HMEPA consider public evacuation
If tank not involved
Protect tank from heat/fire
Extinguish fire
What to do with compressed /liquefied gas leak
25m cordon
Avoid direct contact with cryogenic material
Eliminate ignition sources
Isolate leak if possible
Consider spray to disperse unignited gases
Name 7 Hybrid/electric vehicle hazards
Lithium batteries Explosion risk Toxic fumes High voltage electricity Caustic/ corrosive Unexpected movement from vehicle High bolt age fuel cell fires
Actions on a hybrid/ electric car
Approach from side Information gathering Prevent movement Remove key 5m away Disconnect 12v battery Do not cut orange cables Consider removing fuses or using emergency disconnect Always treat as energised
Auto cut off (battery)
Airbags/pretensioner deployed
12v negative terminal disconnected
High bolt age isolated within fuel cell
What to do with Hybrid/electric car fire
Consider letting it burn out Sealed power pack unit Cool TiC Safety features may be disabled Re-ignition risk
Things to consider with submerged vehicles
If fuel cells not damaged then there is no greater risk of electrocution
If cells damaged then the lithium will react violently with water
Normal water safety precautions should be applied
