Chapter 24 Vehicle Rescue and Extrication Flashcards
A vehicle that uses anything other than a petroleum-based motor fuel (gasoline or diesel fuel) to propel a motorized vehicle.
Alternative-fuel vehicle
Vertical support members that form the sides of the windshield of a motor vehicle.
A-posts
Vehicles that are powered by electricity.
Battery electric vehicles
A type of vehicle frame resembling a ladder, which is made up of two parallel rails joined by a series of cross members. This kind of construction is typically used for luxury, sport utility vehicles, and all types of trucks.
Body-over-frame construction
Vertical support members located between the front and rear doors of a motor vehicle.
B-posts
The separation between the passenger compartment and the engine compartment.
Bulkhead
A vehicle that uses an internal combustion engine for power.
Conventional vehicle
Vertical support members located behind the rear doors of a motor vehicle.
C-posts
Short lengths of timber/composite materials, usually 4 in. X 4 in. (101.60 mm X 101.60 mm) and 18 in. X 24 in. (457.20 mm X 609.60 mm) long that are used in various configurations to stabilize loads in place or while load is moving.
Cribbing
A vehicle that uses both a battery-powered electric motor and a liquid-fueled engine to propel the vehicle.
Hybrid electric vehicle
Safety glass; the lamination process places a thin layer of plastic between two layers of glass so that the glass does not shatter and fall apart when broken.
Laminated glass
One of the vertical support members or pillars of a vehicle that holds up the roof and forms the upright columns of the passenger compartment.
Post
A small opening made to enable better tool access in forcible entry.
Purchase point
An inflatable device used to lift an object or spread one or more objects away from each other to assist in freeing a victim. Various sizes and types are available.
Rescue-lift air bag
A section of a vehicle’s frame located below the doors, between the front and rear wheels.
Rocker panels
Specialized cribbing assemblies made of wood or plastic blocks in a step configuration. They are typically used to stabilize vehicles.
Step chocks
A system that uses supplemental restraint devices such as air bags to enhance safety in conjunction with properly applied seat belts. Seat belt pretensioning systems are also considered part of an SRS.
Supplemental restraint system (SRS)
A type of safety glass that is heat-treated so that, under stress of fire, it will break into small pieces that are not as dangerous.
Tempered glass
The frame construction most commonly used in vehicles. The base unit is made of formed sheet metal; structural components are then added to the base to form the passenger compartment. Subframes are attached to each end. This type of construction eliminates the rail beams used in body-over-frame vehicles.
Unibody (unit body) construction
Material used to tighten or adjust cribbing and shoring systems.
Wedges
Wedges or blocks of sturdy materials that are placed against a vehicle’s wheels to prevent accidental rolling during extrication.
