STRUCTURAL COLLAPSE Flashcards

1
Q

Structural collapse is a SINGLE COMMAND event and FDNY is IC

Structural collapse id defined as any incident where a building or portion of a building including walls, floors, ceilings, partitions, or structures such as bridges, scaffolds, signs , construction sites and banner have collapse for are IN DANGER OF COLLAPSING

A

SEARCH and RESCUE is FDNY core competency

-all city agencies , including PD and BUILDINGS DEPT. , operated under the direction of FDNY

  • LIFE SAFETY operations in progress will not be disrupted or suspended beaus of the arrival or transition of command (CF: ICS)
  • FIRST ARRIVIng FDNY fire officer has prime responsibilities for rescue activities at the incident site and should assume roles of IC….first arriving resources will initiate life safety operations .

-ALL agencies responding to an incident will assist as requested by the IC…personnel from other agencies will be under the control of their superior, who shall report to ICP (FDNY) for instructions

Q

When the RESCUE and REMOVAL of all persons involved in the incident, and stabilization of all threats to public safety have been accomplished , the scene becomes the jurisdiction of DEPARTMENT OF BUILDINGS AND /OR NYS DEPT. OF LABOR (buildings under construction/demo)

A

IC will determine when an area is safe to permit personnel of other agencies, who will be coordinated by OEM into an area to being the process of reservation and recovery

Q

At least ONE TOWER LADDER shall be special called to every MAJOR collapse if none was assigned on the initial alarm.

A

safety considerations:

  • single most important consideration is SAFETY
  • do not enter any danger zones except TO SAVE LIFE
  • place apparatus outside potential collapse zone
  • identify and immediately report any sign of structural defect that could lead to secondary collapse
  • access control points established
  • door , stairways, ladders, ramps, ditches and excavations should be made as secure as possible in the event a rapid escape from the site is required

Note: at all EXPLOSIONS and MAJOR COLLAPSES, SOC units shall ensure that immediate area is monitored for the presence of radiological /chemical agents

Q

IF POSSIBLE , both FIRS AND SECOND ENGINES SHOULD TAKE SEPARATE HYDRANTS OUTSIDE THE BLOCK , EACH ON SEPARATE MAINS and prepare to supply landlines and large caliber Tower ladder stream

A

3rd and 4th engines should take similar positions at the REAR of the structure

-TWO of the 2nd alarm ENGINE COMPANIES should be used to seal off the ends of the street (chauffeurs of these units MUST REMAIN IN THE CAB, ALBE TO MOVE THE APPARATUS )

Q

TOWER LADDERS should be placed in FRONT of the collapsed structure , outside of the COLLAPSE DANGER ZONE

A

initially , the first arriving TL should be the only unit in front of the building, unless there is specific need for additional units, subsequent TL’S should be positioned to reach and protect different exposure

  • at incidents involving tall/long buildings, consider placing several units around the collapse , or using aerial ladders (100 feet )if needed
  • aerial ladders kept AWAY from building in a SECONDARY STAGING AREA
  • rescue companies and collapse units should be placed OUTSIDE the collapse danger zone but as closes as possible to the front of building

ambulances need to be VISIBLE from scene, but out of the way of rescue and firefighting operations
-first arriving ambulances need to be close to the scene to provide supplies for triage and initial treatment

-heavy equipment , such as cranes, front end loaders and dump trucks must also be assure site access

  • ensure access/egress of essential vehicles
  • position apparatus for most efficient use
  • coordinate apparatus staging areas
  • coordinate CASUALTY COLLECTION POINT with an EMS OFFICER
17
Q

Rescue TASK force is assigned on the transmission of 10-60 and a second on 10-60-1..

A 
RTF:
1 rescue compay
1 collapse rescue unit
1 SOC suppor ladder company
1 rescue paramedic unit
1 haz tac officer 
Note: when collapse rescue is transported by an SSL, NO additional SSL is required
18
Q

MARKED off danger zones should not be entered by anyone , INCLUDING FF’S , EXCEPT TO SAVE A LIFE

A

-when EVACUATING, leave behind hose, tools, equipment

at construction or demolition sites, seek out the SITE SAFETY MANAGER or CONSTRUCTION MANAGER for info about previous conditions

19
Q

LCES..

A

-Lookouts , Communications, Escape Routes and Safe Havens

20
Q

LOOKOUTS…

A
  • posted around perimeter of collapse site
  • utilize surveyor transits
  • equipped with HANDHELD AIR HORNS, (battalion, division, soc units and collapse units have hand held air horns)

Brave-Battalion
Dudes-Division
Save-Soc units
Children-Collapse units

21
Q

Communications..

A

evacuation signaling method: hand held air horn or apparatus air horn
1 LONG BLAST(3 seconds)–CEASE operations
3 SHORT BLASTS (1 seconds each)- EVACUATE the area
1 LONG BLAST/1 short blast- RESUME OPERATIONS

-Each SAFETY OFFICER and member monitoring a transit, as well as members positioned as lookouts for hazard monitoring , will be issued air horn

–those operating power tools may not hear the announcement over HT. Apparatus air horns may be beneficial after the initial HT announcement followed by another HT announcement after the air horns have ceased

22
Q

Escape routes.

A
  • all members operating in danger zone must have preplanned escape routes, as well as ALTERNATE ROUTE
  • identify hazards in you operating area and pathway from them
  • know HOW LONG it will take you to reach safety
23
Q

SAFE HAVEN.

A
  • rescuers need to create safe havens in the immediate proximity to the rescue site
  • this may be done by shoring the area where the rescuers are operation so that a secondary collapse will not affect them, or it may mean removing a hazard, such as tying back or pulling over a leaning wall before entering the are below it
24
Q

SAFETY CONSIDERATIONS..

A
  • monitor atmosphere for flammable or toxic gases, as well as sufficient oxygen
  • DO NOT CUT /REMOVE major supports , work around them, if possible
  • if you ABSOLUTELY MUST CUT MAJOR SUPPORTS, brace and shore around them and prepare for SECONDARY COLLAPSES by removing everyone but PERSONNEL PERFORMING the cut
  • rotate personnel frequently , EVERY HALF HOUR or less if possible
  • seek assistance of structural engineers, riggers , through OEM
  • if terrorism suspected , use the apparatus and NYPD to block access to the area …have NYPD check for SECONDARY DEVICES
  • SOC support ladder could be utilized as additional FAST TURCK , working within search and rescue sector or branch
25
Q

SOC support LADDERS.

A
  • trained in collapse ops, void access and shoring techniques
  • assist rescue in TUNNELING and VICTIM REMOVAL
  • act as SECOND FAST UNIT , working under search and rescue branch
26
Q

CON EDISON VACCUM TRUCKS.

A

ONLY USED BY TRAIN MEMBERS OF SOC in conjunction with CON ED operators at the direction of IC

27
Q

5 Stages of COLLAPSE rescue operations:

A
  1. RECONNAISSANCE
  2. ACCOUNTING FOR AND REMOVAL OF SURFACE VICTIMS
  3. SEARH OF VOIDS
  4. SELECTED DEBRIS REMOVAL AND TUNNELING
  5. GENERAL DEBRIS REMOVAL
28
Q

RECONNAISSANCE..

A
  • determining WHERE to start looking is key to victim locating victims
  • NO LIVES SHOULD BE RISKED TO RECOVER A BODY
29
Q

Accounting for REMOVAL OF SURFACE VICTIMS

A

-removal of victims who are lightly pinned
-OFFICER should be designated to keep track of all person who are removed from debris
OFFICER should obtain name and where they were located, if times permits, ask persons to point out escape route
VICTIM ACCOUNTING MANAGER:
-make note of any injuries /if transportation involved , to what hospital and by whom

-use Fire Marshals for interviewing victims and canvassing hospitals

30
Q

VOIDS:

A

LEAN TO VOID(produces LARGE VOIDS that may contain survivors)and unsupported lean to is extremely dangerous and must secured early

  • failure of the support at one end of a floor or roof, ONE bearing wall gives way while the other remains intact
  • everything on the floor will be thrown in a heap at the low end
  • EXCELLENT chance of survival for persons who were on the floor below if they were near the remaining wall
  • SMALLEST chance of survival is for anyone on the lower floor in the vicinity of the failed wall

V SHAPED VOIDS : (directly below will have LEAST CHANCE of survival/those along PERIMETERS will have greatest )(large voids along remaining walls , likely survivors)

  • result when floor fails in the MIDDLE
  • WALLS AND FLOORS ABOVE usually remain intact, although any floors below may collapse because of WEIGHT of falling debris
  • produces 2 VOIDS on the sides of debris, both of which should be searched
  • victims and debris thrown toward center on collapsing floor

PANCAKE COLLAPSE :

  • floors fall in layers
  • survival depend on the presence of strong objects nearby to keep the weigh of the entire load fro landing on a victim
  • items can hold up floor above , which often remains intact
  • locating the victims is often simpler than in the types of collapses , since floors usually maintain physical aspect and the victims aren’t thrown
  • it may be possible to crawl in and out of space between floors (shoring should be installed )

INDIVIDUAL VOIDS:

  • may be found in any type of collapse
  • result from spaces formed by strong object that prevent a collapse into the particular section
  • difficult to locate , occur at random
  • searching void spaces should be done IMMEDIATELY after the SURFACE victims have been removed , or simultaneously if sufficient personnel are available
31
Q

Locating Victims:

A
  1. HAILING (VERBAL CONTACT)
    - Around the clock method–members positions themselves at various locations and take turns calling out
  2. PASS ALARM/FEEDBACK ASSISTED RESCUE :
  3. EMERGENY ALERT TONE ASSISTED RESCUE
  4. INTERVIEW WITNESS
    - Collapse survivor interview form/LUNAR
  5. EXPLORING VOIDS
    - utilize THERMAL IMAGING CAMERA
  6. ELECTRONIC LISTENING DEVICE
    - Life detection systems on all collapse rescue units
    - probes placed at top of debris pile to detect sound/vibration
    - not practical during INITIAL STAGEs of collapse
    - appropriate to use this device once the void exploration phase is complete and ALL KNONW VICTIMS HAVE BEEN REMOVED during SELECTED DEBRIS REMOVAL
    - Remove all personnel from debris pile and shut down all moving equipment before using these devices
  7. SEARCH DOGS
    - FEMA USAR TASK FORES
32
Q

First aRRIVING UNITS may be forced to perform some emergency shoring…units other than rescue and squad SHOULD NOT cut LOAD BEARING ELEMENTS (SOC can support rescue in shoring )

A

FDNY will only install shoring:

  • human life is in danger/provide safe area around victim /rescuers
  • shoring will permit building to remain safe to occupy
  • vacant/unoccupied will NOT be shored when there is substantial risk to members
  • building with no civilian life hazard: if shoring can be safely installed, with minimal risk to members and substantial property safeguarded
  • building will be DEMO, no shoring , unless it facilitates rescue operations
  • once installed, shoring will only be removed when the load is otherwise stabilized or the situation permits the shores to removed from a safe location
33
Q

Selected Debris removal stage beings when ALL VOIDS have been searched and people are still UNACCOUNTED for.

A

it is NOT a useful tactic if we have no idea where the victims are (SELECTED), only when victims are SUSPECTED to be in a certain area
-when tunneling/trenching…30 minutes recommended maximum work time

SOC units and ENGINE/LADDER can be part of SUPPORT GROUPS (assist SOC units)

34
Q

if victim has been pinned for MORE THAN 1 HOUR, RESCUE PARAMEDIC must be given access to the patient …treat crush syndrome

-AS LONG AS AREA IS STABLE and patient is sufficiently exposed to permit IV (arm , leg, neck..don't need full body access)
SMILING DEATH (prolonged compression usually 4-6 hours, could be less than 1)
A

once all LIVE victims have been removed, selected debris removal should cease (risk live of members to retrieve a boy is NOT JUSTIFIED )

35
Q

GENERAL DEBRIS REMOVAL

A
  • persons still missing, location unknown, remove all ruble and strip the area
  • certain there are NO other survivors and all voids have been searched
  • special trained dogs can be used….despite heavy equipment required, FDNY will over see operations
  • each load of debris must be spread out on the round and throughly examined
  • all debris deposited in the debris examination areas

Demolition Debris Removal LOG must be maintained when there are still VICTIMS unaccounted for….it is necessary to examine every inch of the structure

36
Q

VICTIM REMOVAL TOOLS.

A
  • jackhammers, concrete cutting saw and torches for CLASS 1 BUILDINGS
  • chainsaws for most buildings with wooden floors and roofs
  • CRANES, bulldozers, etc….heavy demo equipment is FORBIDDEN durinG SELECTED DEBRIS REMOVAL

-once operations come with REACH of the victim, all work should proceed with only HAND POWERED TOOLS, unless object and victim are visibly clear and NO INJURY LIKELY (BLUFF: MUST)

  • battery and electric tools are preferred over gasoline powered tools
  • use SAWZALL instead of a torch to cut steel (sparks )

-speed , working room and length of operation will impact tool choice

37
Q

FD remains at collapse site until DEBRIS REMOVAL phase is complete or IC is reasonably certain all victims have been removed

A

FD watch line maintained as long as persons operating in the debris pile
-IC must ensure written log of all visitors and investigators are maintained and then forward to CHIEF OF OPERATIONS

ALL TOOLS ARE EXPENDABLE (no lives risked )
