"Rollover should serve as a warning that the fire area may be reaching the point of ________"
"Rollover should serve as a warning that the fire area may be reaching the point of flashover"
TRUE / FALSE
If a firefighters fist barely touches the handrail on either side, the hose line can fit through the well hole.
Page 3
FALSE; " If a firefighters fist does not touch either handrail, it is generally acceptable to perform a well-hole stretch without the possibility of the hose wedging in the well, once charged. "
FALSE
Todays fire burns at a rate of 10% faster with rapidly increasing heat compared to fires of just 20 years ago.

1. Fire Resistive
2. Non-Combustible
3. Ordinary
4. Heavy Timber

List the components of the Fire Tetrahedron
Oxygen- sustains combustion
Heat- Raises material to ignition temperature
Fuel- any combustible material
Chain Reaction- when all three elements above are present in their necessary condition.
This decision making method is a step-by-step, logical sequence that the decision maker uses to reach the best decision.
One weighs advantages, disadvantages; risk/ benefit, and finally chooses how to solve the problem.

Are all signs of what?
backdraft
The stage of fire at which all surfaces and objects within a space have been heated to their ignition temperature and simultaneously ignition of all surfaces and objects in the space occurs.
between growth and fully developed
Flashover
*** Between growth and fully developed ***
On a residential street, telephone poles are typically spaced approximately ____ feet apart.

Reading Smoke Page 17
if the smoke is not moving, it is not getting any air, meaning the fire may be lying dormant waiting for ...
additional oxygen or burned out
Observed when flames present in layers of smoke as result of heated gases that are pushed under pressure from the fire area into uninvolved areas.
Rollover
an explosion that occurs when additional oxygen is introduced into a smoldering fire as heated gases enter their flammable range.
typically exist during the decay stage
Backdraft
** Typically exist during the decay stage after the fire compartment has consumed all available oxygen**
the engine company officer is the interim incident commander by default.

Page 47 Definition:
this maneuver is used to move through a compartment where high heat or pre-flashover conditions exists to the point that the crew cannot safety advance their hose line to extinguish the seat of the fire

the heat of the expanding smoke is ________ as smoke flows across the ceilings, walls, and doors.

During this stage of fire growth, fire develops and rollover is often seen, in an adjacent compartment.

Hose Lay- Page 63
Type of lay used when the first due engine will not pass the hydrant enroute to the scene.
Split lay, is used when either the distance from the hydrant to the scene is too great or when the first due engine will not pass hydrant enroute to the scene.

continuing to grow
A decision- making method that uses ones intuitive reaction to problem solve. One uses sights, sounds, smells, and other sensory cues to trigger the memory of similar situations.
One's actions are chosen quickly.

RPDM Recognition Primed Decision Making
the initial incident commander has two options when making a command statement
Hold Command: only appropriate when 1-2 units are operating
Request to Transfer command: request to transfer command through the first due responding BC
page 64
tactical priorities of the first due engine shall include: ( 3 things )
actions required to facilitate a rescue
actions required to minimize fire spread
actions required to extinguish a fire
During this fire growth stage, the entire room and contents are involved in fire.
Fire will continue to burn until the available fuel and oxygen in the room or area is consumed or extinguished.
