Chapter 17: Fire Suppression
Defensive
A fire operation conducted from the exterior of the building or fire compartment, or while moving away from the fire, by directing water streams toward the fire from a safe distance is considered:
Droplets
A fog stream divides water into _______ which have a very large surface area and can absorb heat efficiently.
Straight stream or multiple fog-stream patterns
A fog-stream nozzle adjusts to produce what type of stream (s) ?
A Solid Stream
A smooth-bore nozzle produces what type of stream ?
Structural Collapse
An offensive attack typically exposes Firefighters to the heat and smoke of the fire inside the building as well as several other risk factors, such as the possibility of being trapped by __________ ________.
Indirect attack
Applying water to the hot gases by sweeping the ceiling with water to cool the gases and droplets is an example of what type of attack ?
Conditions Actions Needs
BFD's size up should include CAN which stands for:
Actions that are intended to control a fire by limiting it's spread to a defined area avoiding the commitment of personnel and equipment to dangerous areas
Defensive Operation
high-volume handlines
Defensive operations often use ____-______ ________ or master streams from a safe position to control the fire
Direct attack
Delivering water directly onto the base of the fire is an example of what type of attack ?
Nozzles
Different types of fire streams are produced by using different types of _______
Firefighting operations involving the application of extinguishing agents directly onto the burning fuel.
Direct Attack
20
Firefighters should operates a hose stream at a distance of at least __ feet from the solar panels
Fire Triangle
Fuel, Oxygen, and Heat are referred to as the:
Firefighting operations involving the application of extinguishing agents to reduce the buildup of heat released from a fire without applying the agent directly onto the burning fuel.
Indirect attack
An elevated master stream appliance that is mounted at the tip of an aerial ladder or tower ladder.
Ladder pipe
Actions generally performed in the interior of a involved structures that involve a direct attack on a fire to directly control and extinguish the fire.
Offensive Operation
The material covering the gap between the edge of the roof and the exterior wall of the house. The soffits in most modern houses contain a system of vents to maintain air flow to the attic area. Some attics may have sealed soffits to create a conditioned air space for energy conservation.
Soffit
A general term for thermal collectors or photovoltaic (PV) modules
Solar Panel
A power system designed to convert solar energy into electrical energy; may also by referred to as a PV system or solar power system
Solar Photovoltaic (PV) systems
A solid column of water
Solid Stream
A stream made by using an adjustable nozzle to provide a straight stream of water
Straight stream
True.
TRUE or FALSE: it is hard to completely mitigate the electrocution hazard from PV systems because most PV systems cannot be turned off with a single disconnect switch.
Fuel Oxygen Heat A Chemical Chain Reaction
The Fire Tetrahedron consists of
all of the tactics and tasks that are performed on the fire scene to achieve the final goal of extinguishment of the fire.
The term "Fire suppression" refers to:
Fuel Oxygen Heat
To stop the combustion process, you must remove one of the following three:
An offensive attack initiated by an exterior, indirect handline operation into the fire room to initiate cooling while transitioning into an interior direct fire attack in coordination with ventilation operations
Transitional Attack
Offensive
When Firefighters advance hose lines towards a . building to attack a fire, the operation is considered:
