Engine Company Ops Flashcards
Pull pass or stop short how many addresses
2 addresses
Small, wall mounted safe that holds building keys for retrieval by fd,ems and police during emergency situations.
Knox box
Occurs when all surface and objects within a space have been heated to their ignition temp and simultaneously combust.
Flashover
Can take place at the point between growth and fully developed stages of a fire
Flashover
Is an explosion that occurs when oxygen enters an oxygen-deficient smoldering fire.
Backdraft
Conditions typically exist during a fire’s decay stage, after the fire compartment had consumed all available oxygen
Backdraft
Takes places when pressure from the fire area pushes heated gases into uninvolved areas, causing flames to present in layers of smoke
Rollover
Occurs when fire gases separate into layers according to temp.
Stratification
Gases with the highest temperatures move to the top layers, and the cooler gases move to the bottom layers.
Thermal layering or thermal balance
Amount of energy the fire releases over time.
Heat release rate
RECEO VS
Rescue, exposure, confinement, extinguishment, overhaul, ventilation, salvage.
VSP
Victim Survivability Profiling
Enables a fire to sustain combustion
Oxygen
Includes any combustible material in the form of solid, a flammable liquid or a gas
Fuel
It is needed to raise the fuel to its ignition temperature
Heat
Occurs when the other three elements are present in their necessary conditions
Chain reaction
Begins when heat, oxygen, and a fuel source combine and have a chemical reaction resulting in fire…..also known as what
Incipient stage
“Ignition”
Occurs as fire increases in size from areas if small flames to flames encompassing an entire compartment
Growth stage
Fire envelopes the entire compartment, involving all contents in fire.
Fully developed stage
Begins when the available oxygen can no longer support combustion.
Decay stage
Include man made materials such as plastics, synthetics, polyurethane, and polyester.
Modern materials
Consist of natural materials such as cotton, wicker, solid wood and dimensional lumber.
Legacy or traditional materials
Refers to a collection of airborne particulates and gases entrain and mix into.
Smoke
What is smoke filled with
Carbon and carbon monoxide
Indicates the amount of fuel that is “off-gassing” within a given space.
Volume
Refers to the thickness of the emission and how much fuel is laden in the smoke
Smoke density
Refers to how difficult it is to see through the smoke
Optical density
Involves a systematic look at the entire fire scene to ensure no further traces of fire exist.
Overhaul
Represents the primary focus of any incident
Rescue
Often overlooked. Becomes necessary in larger fires when lacking on scene resources makes extinguishment impossible.
Confinement
Can represent one of the most dangerous and important tasks firefighters perform.
Ventilation
Before any ventilation takes place, the ventilation team must answer the following questions:
What is the fires location?
What is the current ventilation status?
Will adding additional ventilation openings affect fire conditions?
Where is the hoseline?
What is salvage
Property conservation
Taking direct action to mitigate a problem
Offensive mode
To prevent damage to the area around a structure, officer deploy this strategy when they have decided a building cannot be saved.
Defensive mode
Sets the foundation for incident management
Size up
