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:
