Collapse Flashcards
According to CIMS, structural collapse is a ___________ command event and the FDNY is designated as the ____________ for collapse operations.
Single / Incident commander
Note: other single commands are Auto/Boat (first to arrive), confined space, entrapment/ impallment, elevators, fires, down trees
At least one tower ladder shall be special called to every __________ collapse if none was __________________.
Major / was assigned on the initial alarm
What is the single most important consideration during a collapse operation?
Safety
Where should the first and second arriving engines at a collapse position?
take seperate hydrants outside the block, each on seperate mains, and prepare to supply handlines/large caliber streams
Where should the third and fourth arriving engines at a collapse position?
Similar positions to as the first and second engine at the rear of the structure
What should two of the second alarm engines be used for and what should the chauffeurs do?
Seal off the ends of the streets and the ECC’s of these units must remain in the cab, able to move the apparatus as directed by the I.C.
(remaining engines should be positioned well away from scene)
Initially on a collapse, which is the only unit that should be in front of the collapse building, unless there is a specific need for another unit?
First arriving Tower Ladder (placed outside collapse zone)
What is the highest priority of the first alarm engine companies at a collapse?
Extinguish active fire in the affected building and surrounding debris
What is the second highest priority of the first alarm engine companies at a collapse?
Protect exposures
What is the third highest priority of the first alarm engine companies at a collapse?
Extinguish burning vehicles within the vicinity of the collapse
At a collapse with no active fire, what should the engines first to arrive do?
stretch and charge precautionary 2 1/2” lines in sufficient number and length to cover the entire operation. Also a 3 1/2” line shall be stretched and charged to supply the first arriving T.L.
At a suspected terrorist event, what should the engines first to arrive do?
2 1/2” hoselines should be located between two apparatus, or other substantial shielding, to protect personnel from secondary blasts set to injure emergency responsders
In relation to stretching 3 1/2” to a tower ladder, the first arriving engine should
Consider stretching it
FYI – first engine on collapse can not do CFR
In relation to stretching 3 1/2” to a tower ladder, the second arriving engine should
Ensure it is stretched to the T.L.
FYI – 2nd, 3rd and subsequent engine companies can do CFR
Does the 2nd or 3rd engine assit in the removal of lightly buried victims?
3rd engine
In a collapse, which ladder company to arrive shall immediately begin the process of controlling the gas, electric, and water?
2nd ladder company
ensure the dispatcher notified the utility company emergency crews
What are some of the responsabilities of the first arriving ladder company at a collapse?
Scene survey/hazard assessment/remove lightly buried victims and deliver to CCP/perform preliminary void search/do not cut, lift, or remove load bearing members
At construction or demolition sites, who can you seek out for information about previous conditions of the building?
Site Safety Manager or Construction Manager
FEMA Blast signals: 1 long blast (3 seconds)
Cease operations/all quiet
FEMA Blast signals: 3 short blasts (1 second each)
Evacuate the area
FEMA Blast signals: 1 long and 1 short blast
Resume operations
Which is the only unit that carries heavy timber wood for shoring?
Collapse Rescue Units
The SOC dewatering units carry a number of portable pumps, from ________gpm–________gpm
95gpm-800gpm
What are SOC Collapse Pods filled with?
shoring lumber, metal and concrete cutting saw blades, cutting table with templates (CONTAIN NO TOOLS) – only requested by a command chief
Stage 1 of a collapse rescue operation:
Reconnaissance
Stage 2 of a collapse rescue operation:
Accounting for and removal of surface victims
— member designated to obtain victim information is the victim accounting manager–
Stage 3 of a collapse rescue operation:
Searching Voids
Stage 4 of a collapse rescue operation:
Selected Debris Removal and Tunneling
- heavy demolition equipment forbidden in this stage
- -begins when all voids have been searched and people are still unaccounted for
- -not useful if we have no idea where the victims are located
Stage 5 of a collapse rescue operation:
General Debris Removal
What are the four common types of voids?
Lean-To, V-shaped, pancake, individual
The ________________________________ assists during the reconnaissance phase of an operation.
Victim Location Marking System
The search assessment marking system is dynamic, and should updated as new voids become accessible. When new markings are made, the old markings are?
crossed out
What is the size of the marking, what color paint, and how many paint cans should be carried on the apparatus?
2’x2’, lime-yellow paint, 2 cans on the apparatus
vacant building is 18” x 18”
When is the first slash drawn, ex: /
upon entry to a structure/area
When is the second slash drawn: ex: X
when a unit exits structure/area
X = left quadrant
L-103X FDNY company or team designation
X= top quadrant
The time and date that the company/team LEFT the structure/area
X= right quadrant
Hazards (utilities, open shafts, dangerous areas, rats)
X= bottom quadrant
Number of live and/or expired victims STILL INSIDE THE STRUCTURE (0=no victims)
<—V
known or potential victim (can use arrow if victim’s location is not cleary visible)
V with a circle drawn around it
confirmed victim (visually, vocally, or by hearing sounds that would indication a high probability of a victim)
V with a circle drawn around it with a horizontal line drawn through the middle of the V
victim is confirmed deceased
V with a circle drawn around it with a horizontal line drawn through the middle of the V and a vertical line down the center of the V
confirmed victim removed (marking should not be taken to mean the secondary search is complete)
A type of wood-frame building collapse indicated by the structure slowly starting to tilt or lean over to one side:
Lean-Over Collapse
Type of collapse that happens with wood braced-frame construction:
Inward/Outward Collapse
top collapses inward back onto the structure and the bottom collapses outwards on to the street
The impact of an aerial platform master stream striking a veneer wall at close range can cause:
Curtain-Fall Wall Collapse
exterior masonary wall droping like a falling curtain cut loose at the top
Type of wall collapse where the wall falls straight out, similar to a falling tree (top of the falling wall strikes the ground a distance from the base of the wall that is equal to the height of the falling section)
Ninety Degree Angle Wall Collapse
When floor beams pull loose or collapse at both ends, the floor section collapses as a flat configuration:
Pancake Floor Collapse
Classified as a supported or unsupported floor collapse which one end of the floor beams remain partially supported by the bearing wall and the other end of the floor beams collapse on the floor below
Lean-To Collapse
When a floor collapses and an interior partition or wall holds up the center of the fallen floor:
Tent-Floor Collapse
The collapse of a floor at the center of the floor beams:
V-shaped floor collapse
The collapse of additional portions of the original collapse structure, or taller structures, onto smaller structures, causing the collapse of the smaller buildings:
Secondary collapse
