A

Protect the occupants and rescuers again is t the threat of fire

If possible 1st and 2nd engine take separate hydrants outside the block on separate mains and prepare to supply hand lines and LCS
(Exception 1st engine may have to take position within block for use of master stream for fire control and exposure protection)
3rd and 4th should hake similar positions as 1 and 2 except at rear of structure

Q

A company officer can be assigned the staging area manger

A

Yes but but will be relieved as a chief

21
Q

Engine company responsibilities at collapse in order of priority are?

A
  1. Extinguish active fire in affected building
  2. Protect exposures
  3. Extinguish burning vehicles in vicinity of collapse
  4. At scenes where no active fire stretch and charge precautionary lines
    A. 2 1/2 lines to cover entire operation
    B . 3 1/2 to stretched and charged to supply 1st TL (2nd engine boss ensures)
    NOTE if terrorist event is suspected than hoselines should be located between two apparatus or other substantial shielding
22
Q

First engine responsibilities at collapse op

A
  1. officer supervise water supply and apparatus placement (may have to take position in block(
  2. Coordinate with 1st due truck officer
  3. Stretch 2 1/2 hand lines do sufficient length to cover entire site
  4. **Consider **stretching 3 1/2 to TL

Members will remain together as unit unless otherwise ordered by IC

23
Q

Second engine at collapse op

A

Officer

  1. Obtain briefing from IC or first engine officer
  2. Supervise apparatus placement
  3. Ensure 3 1/2 for 1st TL stretched

Members

  1. Assist first with line and TL supply
  2. Remain together as unit unless otherwise ordered by IC
  3. If necessary perform CFR-d
24
Third and subsequent engines under direction of IC may do the following
1. Fire control 2. Stretching additional lines 3. Augmenting the water supply to first alarm units 4. Perform CFR-d duties 5. Assisting the removal of lightly buried victims
25
First arriving ladder at collapse op
Officer Obtain briefing from IC Supervise apparatus placement Has option of splitting up company Members 1. Perform scene survey 2. Perform hazard assessment and control A. Protect members from secondary collapse mark with hazard tape, tie back and crib B. Keep nOn essential members from entering collapse zone 3. Remove surface victims A. Remove lightly buried victims and deliver to Ccp B. If possible question survivors regarding Number ,ID and location of other occupants prior to collapse 4. Perform preliminary void search Do not cut , lift or remove load bearing members Track survivors and send to CCP
26
Second Ladder company at collapse op
Immediately begin the process of controlling gas , electric and water services Officer Obtaining briefing from IC Supervise apparatus placement Ensure the dispatcher notified the utility company emergency crews Members :utilities Assist with life saving Major priority is controlling utilities
27
Third and subsequent ladders at collapse op
``` Search additional line of sight void spaces or exposure Assist with utilities Perform debris removal as directed Cut timbers for shoring as directed Assist with victim. Removal ```
28
What units may help with victim Removal at collapse
Third and subsequent engines 1st truck 2nd truck 3rd and subsequent trucks
29
TL may be used
1. Provide large caliber streams to protect victims and rescuers from fire 2. Aid in rescuing victims 3. Transport heavy tools 4. Allow rescuers to transverse unstable debris .survey the collapse access remote areas act as a working platform for shoring 5 provide observation for secondary collapses
30
When it comes to safety at a collapse incident the acronym LCES stand for
Lookouts Communications Escape routes Safe havens
31
If at a collapse and hear 1 long blast (3 seconds)from an air horn this means
Cease operations
32
If at a collapse and you hear 3 short blasts (1sec each) this means
Evacuate the area
33
If at a collapse and you near 2 blasts ( one long and one short ) this means
Resume ops
34
Personnel at a collapse should be rotated every
30 min or less if possible
35
A collapse POD can only be requested by
Command chief
36
The 5 stages of collapse rescue operation are
1 RECONNAISSANCE 2. ACCOUNTING FOR THE REMOVAL OF THE SURFACE VICTIMS 3. Search of the voids 4. SELECTED DEBRIS REMOVAL 5. General debris removal
37
Reconnaissance stage of collapse op
Occurs during size up | Helps to determine where to start to look
38
Phase 2 of the collapse rescue op is accounting for and removal of surface victims
May be done simultaneously with recon if conditions and personnel permit Immediately designate officer to keep track of all person s removed ( victim account manager) Use fire Marshall's for interview Canvas video cameras Victim account t manger should ascertain this info from victims : 1. Persons name 2. Where located when collapse occurred 3. If time permits : Point out escape route Also make note of any injuries and if transport was involved and what hospital and by whom
39
Searching voids is the 3 rd part of collapse plan
``` 4 common type Lean-to voids V-shaped Pancake Individual voids ```
40
Lean- to void
Results in failure of the support at one end of floor or roof Excellent chance of survival for those under floor below remaining wall Smallest chance for survival anyone on Lower floor in vicinity of the failed wall Unsupported lean- to very extremely dangerous and should be secured early
41
V-shaped void
Result when floor fails in middle Victims directly below collapse will have least chance of survival Those around the perimeters will have the greatest Create large voids along the remaining voids ,these voids are likely locations of survivors
42
Pancake voids
Floors of structure collapse in layers resembling stack of pancakes Locating victims is often simpler than other those of collapses
43
Individual voids
May be found at any type of collapse Voids are difficult to locate for they occur random Searching voids should be done immediately after the surface victims have been removed or simultaneously if sufficient personnel are available If fire is a issue the fire will be trying to fill these voids spaces survival of victims depends on reaching them first preferably with hand line . Trapped victims can be given an spare SCBA or FAST-PAK (not FAST UNITS) Attach search rope to victim to lead rescuers there
44
Locating victims may be accomplished by any of these methods
``` Verbal contact Pass alarm or feed back assist (FAR) Emergency alert tone assisted rescue Interview witness (LUNAR) Explore voids Electronic listening devices Search dogs ```
45
What does LUNAR stand for
``` Location (last seen or reference point) Unit ( member working in) Name Assignment Resources needed ```
46
If information is obtained about possible locations of missing victims these should be relayed to
Victim accounting manager
47
Shoring is something that that first arriving g units may be coerced to do in an emergency . This first alarm units however should not perform cutting of load bearing elements . The following are shoring guidelines for FDNY
FDNY will only install shoring in the following instances : 1. Whenever human Life is in danger 2. When shoring will permit building to remain safe to occupy 3. Buildings in which there is no civilian hazard will only be shored if there is minimal risk to members and where here is substantial property risk that can be safeguarded 4. A vacant or unoccupied structure will not be shored if there is substantial risk to members installing the shoring or the use of shoring is unlikely to substantially improve the outcome 5. If building is going to be demolished even after shoring it will not be shored 6. once installed shoring will only be removed when load is otherwise stabilized or the situation permits the shores to be removed from safe area
48
Selected debris removal is the 4 part of the collapse op
Begins when all voids have been searched and all people have not been accounted for Used to reach specific locations where victims are located or suspected to be Not useful tactic if have no idea where victims are More dangerous than void search
49
Crush syndrome
Involves compromised local circulation Involvement of muscle mass Prolonged compression (4-6 hours possibly less than an hour Prevention is providing an intravenous line before release of pressure
50
General debris removal
Final aspect of the collapse op After all other methods are employed and people still missing and their location is unknown without regard or preference for any particular area Under direction of FDNY
