Chap 16 Vehicle Fire Flashcards
A subset of vehicles, generally utilized for personal use, which include car, vans, and light duty pick up trucks?
Passenger vehicle.
Passenger Vehicle hazards can be broke down into three broad areas?
- Vehicle components
- alternate fuels
- hazardous cargo
Any part of a vehicle, including the mechanical and non mechanical parts, which can be dangerous in vehicle fires.
Vehicle component
Vehicle air bags that utilize technology to determine if an airbag is safe to deploy.. These air bags may not deploy in a vehicle crash when a small passenger is seated or there is no passenger seated.
Smart air bag systems.
What should fire fighters be aware of with an unoccupied seat utilizing a smart air bag system?
The air bag may still deploy under fire conditions.
What do most manufactures utilize to indicate Air bag systems?
Bright yellow wires.
Do not cut
Vehicles that utilize any fuel source other than gasoline or diesel fuel.
Alternative- fuel vehicles
Vehicles that operate utilizing a combination of electrical (battery) power and gasoline.
Hybrid Vehicles
What is one way you can identify a hybrid vehicle?
Check for presence of bright orange components under the vehicles hood.
Considerations highlighted throughout the “Interim Guidance for Electric and Hybrid Electric Vehicles Equipped with High Voltage Batteries”
- Always assume high voltage battery and components are fully charged and energized
- Exposed electical components, wires and high voltage batteries present potential high voltage shock hazards
- Venting/off gassing high voltage battery vapors are potentially toxic and flammable
- Physical damage to the vehicle containing a high voltage battery may result in immediate or delayed release of toxic and/or flammable gases and fire
A vehicle that operates in much the same way as hybrids, but they have a third component that utilizes energy taken directly from the environment. (solar power)
Tribrid Vehicle
First order of business when fighting vehicle fires?
Life safety, protect the fire fighter by properly placing the fire apparatus to block traffic.
Any large truck, such as a box truck, generally utilized for commercial application, but may also be utilized for private use.
Heavy Duty Truck
This is a critical part of the overall strategy in commercial truck fires that is essential for safe mitigation of the incident?
Determining the contents of the vehicle
What must be done before working under a commercial truck involved in a fire?
Cribbing, bc air suspension system can fail during fire and drop several inches.
Large fuel tanks located on the sides of the cab of semitrailer or heavy duty truck, usually under the driver and passenger door.
Saddle Tanks
This is extremely important upon arrival at a semitrailer fire?
Size up
What must be done on all trucks with sleeping quarters, especially when the driver is not present?
Must be thoroughly searched for potential occupants as soon as reasonably possible
Motor homes that are large RVs with a modular body on a frame. Self contained units that can have air conditioners, refrigerators, bathrooms, and generators.
Class A Motor home
These are much like class A motor homes except they have a truck or van chassis and a cab with a modular camping unit attached to the back frame.
Class C motor homes
These are oversized custom vans that have been converted into campers.
Class B motor homes
Some hazards associated with RVs?
- Presence of LPG tanks. Immediate cooling is imperative
- Anhydrous ammonia found in some RV refrigeration systems
- RVs waster or gray water holding tanks
Hazards association with Heavy Construction Equipment fires
- Large tires, which may explode under fire conditions
- large amounts of hydraulic fluid
- Higher positioning of occupants
- Large equipment, such as cranes, that threaten to fall over heavy fire conditions
