Essentials Chapter 7 Rescue And Extrication

Front 1

Rescue

Back 1

incidents involve the removal and treatment of victims from situations involving narural elements, structural collaspe, elevation differences, or any other situation not considered to be an extrication incident.

Front 2

Extrication

Back 2

incidents involve the removal and treatment of victims who are trapped by some type of man-made machinery or equipment.

Front 3

Fire ground scene size up should include...

Back 3

size of the fire, whether or not the building is likely occuiped, the probable structural integrity, and some idea of the time it will take to search the building. Look for additional escape routes, windows and such.

Front 4

What should you question occupants who have escape or neighbors?

Back 4

Where occupants maybe found?
Number of people still inside?
Bedrooms?
Location and extent of the fire?
**No matter what information they give, you still must search**

Front 5

What are the two objectives of a building search?

Back 5

(1)Finding victims, and (2) obtaining information about the extent of the fire.

Front 6

The two types of search are....

Back 6

primary and secondary

Front 7

primary search

Back 7

is a rapid but thorough search that is perfomed either before of during fire suppression.

Front 8

secondary search

Back 8

is conducted after the fire is under control and the hazards are somewhat contolled.

Front 9

Primary search personnel should always carry what?

Back 9

forcible entry tool which can be use to search or force entry to other parts of the building or out.

Front 10

If no or little smoke or heat during primary search walk or crawl?

In a multistory building what are the most critical floors?

Back 12

The fire floor, the floor directly above it, and the topmost floor.

Front 13

Remember to close _____ during primary searh to prevent the spread of fire into these areas.

Back 13

doors

Front 14

When searching open doors by...

Back 14

feel the top and the handle for heat. If hot do not enter with out charge hoseline. If not hot, stay to one side, keep low, and slowly open the door.

Front 15

What to do when your reach a difficult to open door in structural fire?

Back 15

Donot kick, as there may be a victim behind the door and this would cause further harm. Slow pushed or force open and check behind the door for a victim.

Front 16

Disoriented fire fighters MUST REMAIN

CALM

Front 17

What to remember when disoriented and you reach a hoseline?

Back 17

The side of the male coupling leads to the fire truck or exit while the female coupling will lead you to the fire. (The male coupling has lungs on its shand and the female does not.

Front 18

Emergency moves are necessary under the following conditions:

Back 18

* There is fire or danger of fire in the immediate area.
* Explosives or other hazardous material is involved.
* It is impossible to protect the accident scene.
* It is impossible to gain access to other victims who need immediate life-saving care.
* The victim is in cardiac arrest and must be move to a different area (firm surface) so that rescuers can administer cardiopulmonary resuscitation (CPR).

Front 19

Name the four basic types of powered hydraulic tools:

Back 19

Front 25

Scence size up of a possible vehicle extrication should include:

Back 25

* What are the traffic hazards?
* How many and what type(s) of vehicle(s) are involved?
* Where and how are the vehicles positioned?
* Is there a fire or potential for a fire?
Are there any hazardous materials involved?
* Are there any utilities, such as gas or electricity, that may have been damaged? If so, are they posing a hazard to the victims and rescue personnel?
* Is there a need for additional resources?
* Number of vehicle and victims?
* Severity of injuries?

Front 26

The primary goal of stabilization is to

Back 26

to maximize the area of contact between the vehicle and the ground to prevent further movement of the vehicle.

Front 27

When should you push the vehicle to test the stability?

Back 27

NEVER

Front 28

The most common method to prevent horizontal movement of a vehilce is...

Back 28

chocking the wheels.

Front 29

List the different ways to prevent vehicle from moving vertically:

Back 29

Jacks, air-lifting bags, and cribbing are the most frequently used for this purpose.

Front 30

The three general methods of gaining acess to victims in a vehicle are:

Back 30

* Through a normally operating door
* Through a window
* By compromising the body of the vehicle

Front 31

List the two primary types of glass used in vehicles

Back 37

safety (laminated) glass
tempered glass

Front 38

safety (liminated) glass

Back 38

is manufactured from two sheets of glass that are bonded to a sheet of plastic sandwiched between them. The plastic sheet retains most shards and fragments in place.

Front 39

tempered glass

Back 39

manufactured so that small lines of fractures are spread throughout the the entire plate. Breaks out in pieces rather than as a whole.

Front 40

The following common tools can be used to cut laminated glass:

Back 40

-Air chisel
-Axe
-Reciprocating Saw
-Handsaw with a coarse blade such as those used in commercially produced tools

Front 41

You should break tempred glass in the...

Back 41

lower corner of the window

Front 42

List the four common patterns of structural collapse

Back 42

1) Pancake collaspe
2) V-shaped collaspe
3) Lean-to collaspe
4) Cantilever collaspe

Front 43

Pancake collaspe

Back 43

upper floors and roofs collapsing on top of each other such as in a stack of pancakes. This pattern will least likely to contain voids in which living victims may be found, but it must be assumed that there are living victims in the rubble until it is proven otherwise.

Front 44

V-shaped collaspe

Back 44

the outer walls remain intact and the floors and/or roof structure fail in the middle This patter offers good chance of habitable void spaces being created on both sides of the collaspe.

Front 45

Lean-to collaspe

Back 45

one outer wall fails while the opposite wall remains intact. The side of the roof assembly that was supported by the failed wall drops to the floor forming a trangular void beneath it.

Front 46

Cantilever collaspe

Back 46

when one sidewall of a mutistory building collapses leaving the floors attached to and supported by the remaining sidewall. This patter also offers a good chance of habitale voids under the suppored ends of the floors.

Front 47

This collapse pattern is perhaps the least stable of all the patterns and is the most valnerable to secondary collaspe.

Back 47

Cantilever collaspe

Front 48

shoring

Back 48

any of a variety of means by which unstable structures or parts of structures can be stabilized. Not intended to move large objects, just stabilize them.

Front 49

Tunneling

Back 49

primarily involves removing smaller rubble & debris to create a path to a know location of a victim. Because it is slow and dangerous it should be used as a last resort.

Front 50

Trench rescue

Back 50

Rescuers should not be sent into a trench unless their safety can be reasonably ensured and they have been trained. Move all nonessential personnel and equipment back to avoid secondary collaspe.

Front 51

The three things that fire fighters should do when called to a rescue involving electricity:

Back 51

1) Assume that electrical lines or equipment are energized.

2) Call for power provider to respond. Let only power company personnel cut electrical wires.

3) Control the scene.

Front 52

Rescuers should stay how far from a down electrical wire?

Back 52

Away from the downed wires a distance equal to one span between poles until they are certain the power is shut off.

Front 53

Water rescue

Back 53

are situations where a victim is stranded, floundering, or has been submerged for a short period of time (usually less than half an hour). In these cases potential for saving the victim is real.

Front 54

Water recovery

Back 54

are situations where a victim has been submerge for a long period of time and is most likely dead.In these cases recovering the body is the goal.

Front 55

Water rescue methods

Back 55

In this order... Reach, Throw, Roll, and last resort Go.

Front 56

Elevator Rescue

Back 56

Unless there is a medical emergency in the car, reassure the occupants and wait for arrival of elevator mechanic.
