When should member begin preparation for engine company responses?
As they enter quarters bu=y ensuring equipment and PPE are accounted for and in good working order
What provides the officer the opportunity to discuss expectations for the members assigned on the engine.
Line up
What are 2 distinct methods to describe the human decision making process?
Classical method is a step by step.
Naturalistic is an intuitive method
Fire service training falls into what 3 categories?
1.Self study training 2.Company training 3.Multi Unit drill
Todays fires burn at a rate of____ times faster than fires of just 20 years ago.
10 times
Flashover defintion
All surfaces and objects within a space have been heated to their ignition point and simultaneously ignite.
Backdraft definition
Explosion that occurs when additional oxygen is introduced into a smoldering fire as heated gases enter their flammable range and ignite.
Rollover defintion
Flames present in layers of smoke as a result of heated gases that are pushed under pressure from fire area into uninvolved area.
Pyrolysis def
As solid fuels are heated, combustible gases are driven from the substance
Rollover should serve as a warning that
the fire may be reaching the pint of flashover.
HRR is simply defined as
the amount of energy released over time. Heat Release Rate
Ventilation needs should be identified when the officer….
completes their size up.
A properly conducted structural ventilation process typically consists of…
the engine officer and outside vent crew exchanging information about the size up.
To properly hydraulic ventilate
The nozzle is 2 feet from opening at cover 80% of the window or opening used
The fireground principles of smoke are
- Smoke is potential fuel
- Smoke density and color together are an indicator of the flammability
- Velocity and pressure are indicators of heat and flow path.
- Volume is an indicator of fire intensity
- All indicate a profile regarding the location, status and extent of the fire
What is a tactical withdraw?
Coordinated and specific relocation of units and their equipment.
What is an emergency evacuation?
Conditions dicatate the immediate evac of all personnel from an unsafe area or structure.
Offensive mode involves taking..
direct action to mitigate the problem.
Defensive mode is
an effort to prevent the area from around the structure from being damaged.
Indirect attack or combination attack must not be used
in areas where victims may be located or firefighters are operating.
Penciling will immediately decrease building heat within a compartment by
50%- 60%
Way to estimate the stretch is
Setback + width of building + length of building + 25’ per floor + 1 length at the point of attack.
ADULTS acronym used for 2 1/2 inch line

Standpipes
Line selection and placement is who’s responsibility
engine officer
White smoke indicates
moisture or early stage incipient Class A
Grey smoke indicates
Early stage incipient/free burning fire with class A and B fuel sources.
Grey/Black or Brown smoke indicates
Fully developed fire that is most likely vent limited.
Black/Brown smoke indicates
Fully developed or decaying stage fire that is extremely vent limited.
Speed of smoke provides what two critical pieces of info on fire ground?
General location of heat source and fires current flow path or air track.
Mercury Monitor Fog nozzle gpm and reach are?
500gpm/ 185’
Estimating stretch is what?
Setback + width of building + length of building + 25’ per floor + one length at the point of attack.
ADULTS acronym for 2 1/2in line is?
Avanced fire conditions. Defensive operations. Unkown fire location. Large open area. Tons of water. Standpipes
