Ch 10 Structural Search and Rescue Flashcards
What is primary search… p456
A primary search is intended to rapidly determine the location of victims. The search should be fast but thorough and may be performed either before of during fire suppression operations. During the primary search, quickly check the known or likely locations of victims and all affected areas of the structure.
What is the main rule of thumb in low visibility environments?
If you can’t see your feet, don’t stand.
What are the two types of orientation that CFD uses?
Overall (of entire structure. Left or right)
Room (within a compartment. Near, left, far, right side)
You must be aware of psychological effects of obscured vision conditions and recognize when they occur… p434-435
What are four psychological effects to be aware of?
Disorientation
Fear
Claustrophobia
Panic
Air consumption varies widely from individual to individual. A cylinder’s rated operating time is not an indicator of actual operating time because of these variations.
True. p437
What are some search safety guidelines… p454
Do not freelance
Maintain in contact with crew members at all times (sight, touch, hearing)
Continuously monitor radio communications
Be aware of your entry point and the secondary means of egress from the structure
Secondary search… p456
A secondary search is a slow, thorough search conducted after the fire is under control. The search’s purpose is to ensure that no occupants were overlooked during the primary search.
Personnel who did not participate in the primary search are often ordered to conduct a secondary search. Using different personnel to conduct the secondary search has the advantages of allowing the search and rescue team to use “fresh eyes” and get an unbiased view of the scene.
What are some basic search methods… p457
General methods for primary and secondary searches follow a pattern. When you enter a room, you turn right or left and follow the walls around until you return to your starting point. As you leave the room, turn in the same direction you did as you enter and continue to the next room to be searched. For example, if you turned left when you entered the room, turn left when you leave the room.
Why is door control important… p460
Close the doors to any rooms that are not involved in fire unless the door are being used for ventilation. This prevents fire from spreading into these rooms. Opening doors and windows can disrupt ventilation efforts, spread fire, and draw it toward the opening.
What is VEIS… p463
VEIS (Vent Enter Isolate Search) is usually chosen as a rescue tactic when there is a credible report of possible victims in survivable areas of the structure.
When emergency assistance is needed - MAYDAY protocols…
GRAB LIVES… p468
If you think your life is in immediate danger, transmit you departments MAYDAY signal, communicate your situation to command, then activate your pass. The sooner rescuers know you are in danger the sooner they can come to your aid.
Remember your GRAB LIVES procedures. Gauge Radio Activate PASS Breathe, Orient, Act Low Illuminate (light) Volume (make noise) Exit Shield (your airway)
Evacuation and immediate actions to improve your survival… p470
Stay low to the floor (lower temps)
Use hose stream for protection (cool gases)
Close door between you and the fire (barriers)
Filtering toxic air (shielding airway)
Use tools to shore up building material
Escaping to a safe haven is the best option in any of the following circumstances… p470
There is an imminent threat of structural collapse
There is no safe place to shelter
You have completely exhausted your air supply
Rapid fire development is about to occur
You have been ordered to abandon the structure
What are Rapid Intervention Teams… p473
Consists of two firefighters and are on standby when firefighters become injured or trapped in the hot zone. They must be trained in firefighter rescue and equipped with the same PPE as interior firefighting crews at the incident. Sometimes more than one RIT is assigned to standby, especially if interior crews entered the building at multiple points.
Mandatory equipment can described as AWARE (Air, Water, A Radio, Extrication):
- A spare SCBA to provide breathing air to downed firefighter
- A hose line to create a defensive space
- A radio to communicate with command
- Forcible entry tools for extrication
Building floor plan and preincident planning… p450
Many fire departments perform periodic preincident surveys of target hazards in their response areas. Preincident surveys allow departments to meet the facility’s owner/occupants and become familiar with the contents, floor plans, building construction, and manufacturing processes.
Attend local zoning meetings; go to a real estate agent’s open houses, and get to know local building officials to gain knowledge.
Fire isolation during search… p 454
Locating and isolating the fire must be a priority before any search. Isolating the fire may be accomplished in a number of ways, depending upon circumstances at the scene. Entering to perform a search provides a ventilation opening to the structure. As a result, even though the intention of a search is to locate victims, ensuring that the fire does not spread beyond the compartment of origin should be a high priority to protect victims and firefighters.
Wide area search method… p461
A wide area search method is sometimes used to conduct a primary search of a large or complex area that is filled with smoke. This system employs a dedicated search line, typically 200’/60m that is 3/8” thick rope. A minimum of three team members are required, although larger teams can be more effective. About 10’ or 3m outside the entry point to the search area, the end of the search line is tied to a fixed object about 3’ or 1m above the floor.
Victim removal techniques… p466
Never drag a victim through a hazard zone unless there is no other choice. Use the following types of carries or drags to remove a victim: Incline drag Extremity carry Webbing drag Cradle in arms carry Seat lift/carry Litter carry
Breaching an interior wall may give you access to a safe haven or room from which you can safely exit the building… p472
However, this is not a preferable method since it requires strength, depletes air supply, and creates an additional flow path.
Search methods 2… p458
One good search practice is to get low to the floor to perform a quick survey. Thermal layering and the buoyancy of smoke produce a clear area of vision just above the floor level. Victims, obstacles, or the general layout of a room may be identified more quickly from this perspective.
Building Floor Plans…
To conduct an effective structural search, FF must know the layout or floor plan of a building.
This knowledge may come from inspections, preincident surveys, architectural plans, or personal observations.
What is shelter in place… p465-466
Sheltering in place involves moving to a protected location within the structure.
It is used when:
The hazard is minor
It is safer to keep the victims inside the structure
Victims are incapacitated and cannot be moved
There is limited staffing to assist with the evacuation
The structure can provide a protective barrier between the victim and the hazard
Victim removal techniques 2… p466
Injured victims should not be moved until they have been assessed and treated, unless they (or you) are in immediate danger. The primary danger in moving victims quickly is the possibility or aggravating a spinal injury.
When may the IC order for a brief shutdown of all equipment that is making noise? p474
The IC may order a brief shutdown of all pumps, generators, fans, and other noise producing devices so that a firefighter’s PASS device can be better heard.
