Rescue

Removal & treatment of vitims from natural elements, strucutal collapse and elevation differences.

2

Extrication

Removal & Treatment of victims who are trapped by some type or man-made machinery & equipment

3

Two objectives of search

- Find vivtims ( searching for life)

- Obtaining information about the extent of the fire.

4

Types of Search

- Primary- rapid but thorough performed before or during fire suppression

 - Buddy system, 2 or more, forcible entry tools, search on the fire floor close to the fire and work away. 

- Secondary- After fire is under control, conducted by personnel other that the ones who did primary, very thorough

5

Multistory Building search

(Highest Priority) Most critical area is Fire floor,  Floor directly above fire and top

- then intervening floors

- close doors to prevent fire spread 

6

Door Marking system

Chaulk, Crayon, Tape, Door markers, Latch straps over door knob.

/ means being searched,   X means search completed

7

Vitim Removal

Emergency moves, fire or danger of fire in immediate area, explosives or other hazards are involved, impossible to protect accident scence, impossible to gain access to other victims who need immediate care, Victim in cardiac arrest

Lifting improperly is one of the most common causes of injury to rescures

8

Types of victim removal

-Cradle in arm cary- effective for carrying children or very small adults

- Seat lift carry

- Two or three person lift carry

- Immobilizing a victim who is suspected of having a spinal injury requires 4 rescuers

9

10

Inverter

Set up transformer that converts a cehicles 12 or 24 volt DC current into 110 or 220 volt AC current.

 

When small power is needed

- Advantages, fuel efficency, low or nonexistent noise

- Disadvantages , limited power supply, limited mmobility from vehicle

11

Generators

Most common power source used (portable or Vechicle mounted)

PTO,Hydraulic, Propane, Gas or Diesel

110 or 220 volts

12

Portable Lights

Telescoping lights

300 to 1000 watts

500 to 1500 watts

13

Maintaining power plants & Lighting equipment

Inspect & run once a week, Check Gas & Oil after each use,

wear gloves with quartz bulbs " hand oil can cause bulbs to explode"

Inspect spark plug, wires and carb weekly, change gas every 3 weeks

14

Four basic types of powered hydrauulic tools

 

-Spreaders

- Shears

- Combination spreader/shears

- Extension rams

 

15

Spreaders

Pushing or Pulling

-upto 22,000 psi of force at tip

- spread as much as 32"

16

Shears

-upto 30,000 psi of cutting force

- opening approximately 7"

17

Extension Rams

Pushing force about 15,000 psi with closing force about half that

- Extend from 36" closed to nearly 63"

18

Manual Hyraulic tools

&

Disadvantages

Porta Power & Hydraulic Jack

Porta Power can operate in tight spaces (Time Consuming)

Hydraulic Jack (Lifts upto 20 tons)

19

Non Hydraulic Jacks

"Considered hand tools"

Screw Jack- Bar screw Jack, Trench screw jacks

Rachet jacks " Highlift" Lease stable

20

Cribbing

Stailize objects, wedges for shims, solid straight, Free of flaws like knots and splits

2X4 & 4x4 (16"-18")

Ends may be painted for easy ID or length

21

Pneumatic Tools

(Air Powered)

Chisels also called pneumatic hammers or impact hamer 100 to 150 psi

22

Lifting/Pulling tools

Tripod, Winches, Come alongs (1-10tons), Chains, Air bags & Block & Tackel

23

3 Common Winches

Electric, Hydraulic, PTO

24

Chain

Only allow steel chain of the correct size

Proof Coil chain also called common or hardware chain is not suitable

 

25

Airbags and Types

Never stack more then 2 high or on metal hotter than 220 degrees

- High Pressure 1" high 6"X6" to 36"x36" upto 20"

- Low and Medium pressure bags are considerably larger lifts upto 6'

26

Block and Tackle

Block is a wooden or metal frame with 1 or more pulleys called sheaves

Tackle is the assembly of ropes & blocks through which the line passes

27

28

Gaining access to vitims

3 ways

Door, window, Compromising the body of vehicle

29

SRS & SIPS

Airbags

Supplemental Restraint System

Side Impact Protection Systems

-Airbags operate electrically or mechanically operate at 200mph

 

30

Packaging

Means that wounds and fractures have been dressed and immobilized
