Ch 6 Tactics Flashcards
________ involves the techniques that allow a rescuer to identify the location of victims and determine how to access those victims in order to remove them to a safe area
Search
_______ is the removal of victims from an untenable or unhealthy atmosphere
Rescue
In some cases,_____ of the fire must be initiated prior to the search and rescue effort for the sake of the firefighters and occupants safety
Confinement
A __________ is a rapid but thorough search that is performed either before or during fire suppression operations
Primary search
A _________ is conducted after the fire is under control and the greatest hazards have been controlled
Secondary search
_________ should only be initiated following a 360° size up of a structure, and the IC should consider risk assessment when making the VEIS assignment
VEIS
________ exposures are other structures, equipment, vehicles, people, or natural features that the fire would endanger
External
_________ exposures are unburned or unaffected portions of the building interior that the fire growth threatens
Internal
Fire exiting an opening with a defined neutral plane indicates that the opening is supporting a _______ flow of products of combustion away from the fire and oxygen towards the fire
Bidirectional
________ includes firefighting operations required to prevent fire from extending from the area of involvement to uninvolved areas or structures
Confinement
A direct attack on the fire using a solid or straight stream uses water or foam most efficiently on _______ fires
Fuel controlled
An ________ attack on the fire using a straight or solid stream uses water most efficiently on ventilation controlled fires
Indirect
An indirect attack can be considered_______ if performed beginning on the exterior
Transitional
Fire that is located in a remote part of the structure or hidden from view by objects in the compartment
Shielded fire
The _________ is an offensive tactic used in an offensive strategy that the I C or initial company officer employees in which a hose line is deployed from the exterior of the structure where smoke and flames are visible to gain control of the fire prior to deployment of interior hose lines
Transitional attack
The transitional attack is an offensive tactic used in an _____that the I C or initial company officer employs in which a hose line is deployed from the exterior of the structure where smoke or flames are visible to gain control of the fire prior to the deployment of interior hose lines
Offensive strategy
A ________ should be used during every size up to assist in locating the fire within the structure
Thermal imager
The firefighters conducting the transitional attack should ensure that the nozzle is not placed on a_______ and must avoid movement of the street or solid water stream within the opening
Fog pattern
In order for the fan to create the needed pressure to force the heat and toxic gases out of the structure, the_____ must be located in the fire compartment
Exhaust openings
Prior to beginning_______, an attempt to determine the cause and point of origin should be made
Overhaul
Fire officers who are certified to ______should be able to determine the cause and origin of most fires
NFPA 1021
__________ is the planned, systematic, and coordinated removal of heated air, smoke gases, or other airborne contaminants from a structure, replacing them with cooler and fresh air to meet incident priorities of life safety, incident stabilization, and property conservation
Tactical ventilation
_______________ should only be performed when the fire attack hose lines and teams are in place and ready to advance toward the fire
Tactical ventilation
When a window fails, a new source of oxygen is suddenly available to a fire. The fire can rapidly move toward and consume this oxygen, creating a______ affect
Blow torch
_________ commercial structures, such as big box stores, have high fuel loads in the contents and no physical barriers to prevent the spread of fire and smoke in the space
Open plan
In single-family residential structure, the footprint of houses has increased over 150% between 1973 and 2008. At the same time, lot sizes have shrunk approximately _______
25 %
_________ is volume between an inlet and an outlet that allows the movement of heat and smoke from the higher pressure within the fire area towards the lower pressure areas accessible via doors and window openings
Flow path
The _______ Is the connection between the inlet in the outlet
Flow path
The most important weather related influence on ventilation is _____
Wind
That means used for horizontal and vertical ventilation are natural, mechanical, and_______ ventilation
Hydraulic
_________ ventilation involves opening doors and windows to allow natural air currents and pressure differences to move smoke and heat out of the building
Natural horizontal
__________ ventilation uses the buoyancy of heated smoke and gases to draw them out of the structure through the roof openings while entraining fresh air into the structure
Natural vertical
________ ventilation is the oldest type of mechanical ventilation
Negative pressure
When the natural flow of air currents in the currents that the fire creates are insufficient to remove smoke, heat, and fire gases,_______ ventilation is necessary
Mechanical
Vertical ventilation is the opening of the______ part of the structure to allow smoke, gases, and heat to escape
Upper
If a basement fire is found and there is no exterior access to deploy hose lines for fire attack, consider a ______ attack through ventilation of exterior basement windows prior to making entry
Transitional
The personnel required for search rescue and firefighting operations in high-rise buildings is often four to ______times as great as required for a fire in a typical lowrise building
Six
Openings within a high-rise can contribute to a _______, creating an upward draft and interfering with evacuation and ventilation
Stack effect
Tendency of any vertical shaft within a tall building to act as a chimney or smokestack, by channeling heat, smoke, and other products of combustion upward due to convection
Stack effect
________ is defined as methods and procedures that firefighters used in attempt to save property and reduce further damage from water, smoke, heat, and exposure
Salvage
The most important aspect of tactical ventilation in high-rise buildings is the ability to confine the fire to its ______ or floor of origin
Compartment
