exam questions Flashcards
Ch. 14 pg. 429
Windowless buildings limits the opportunities for horizontal ventilation, and increases the likelihood of:
A. heavy smoke conditions
B. smoke in the stairwells preventing escape routes
C. back-draft conditions
D. floor collapse from high heat conditions.
C. back-draft conditions.
Ch. 14 pg. 422
Before attempting to ventilate the fire floor, knowing the layout of the building is extremely important. Trying to ventilate to a dead-end corridor or through a stairwell that does not terminate on the roof can delay fire control and increase both fire and smoke damage. to avoid risks of horizontally venting a high rise building, How can ventilation be achieved:
A. Pressurizing a roof terminating stairwell
B. Mechanically ventilating up a stairwell, across the fire floor and out the roof via another stairwell.
C. using the reverse smoke stack principles and venting below the fire floor.
D. isolate smoke to the fire floor to ventilate after evacuation is completed.
B.
ch. 14 pg. 417
The timing and coordination of ventilation with rescue and fire suppression operations is extremely important. Before the stairway doors on the fire floor are opened what action needs to be completed:
A. evacuation from floors above fire floor.
B. Shelter in place order for those above fire floor
C. Bulkhead doors blocked open
D. horizontal ventilation to remove smoke from upper floors.
C. bulkhead doors blocked open.
this makes one stairwell used for ventilation and other stairwells can be used for evacuation.
Ch. 14 pg 423
Ventilating above the fire floor will be most effective if the process is started at the:
A. bottom of the building
B. top of the building
C. on the fire floor
D. using positive pressure fans to charge the building before any openings are made.
B. top of the building
provides a clear path for the smoke and heat to be released when the fire floor doors are opened.
Ch. 14 pg 411 High rise fires present numerous challenges for fire fighters. moving massive amounts of tools and equipment is often coordinated by those assigned to: A. Incident command B. Lobby control C. Staging D. Fire Attack
B. lobby control
this equipment is moved up to the staging area to be used by FA and S/R on upper floors.
Ch. 4 pg. 102 During overhaul firefighters that miss subtle danger signs such as creaking, or other signs that might otherwise alert them to an impending structural collapse are experiencing: A. Tunnel vision B. Mental exhaustion C. physical exhaustion D. Fatigue
B. Mental exhaustion
physical exhaustion- reduces strength and coordination and slows reflexes
fatigue- could make fire fighters less capable of reacting to and escaping from any dangerous situation that might suddenly develop.
Ch. 4 pg. 109
One of the most effective means for reducing secondary loss is by:
A. judiciously spraying water
B. Performing loss control as soon as life safety has been achieved
C. performing rapid and effective salvage
D. completing overhaul in a timely manner
C. performing rapid and effective salvage.
Ch. 4 pg. 111
Once the portable contents of the fire floor have been removed, firefighters can concentrate on saving the contents of the floor above because fires tend to spread upward. Fire fighters must do everything necessary to protect their means of egress while they work. What is a possible action to protect egress?
A. should always be two widely separated exit locations
B. Have a charged stairwell for primary egress
C. Mark egress location with light or search tape
D. maintain radio contact with fire attack
A. should always be two widely separated exit locations.
also suggested is to assign a crew with a charged hose line to monitor and protect the primary exit.
ch. 11 pg. 289
As a fire is developing and in the early growth stages, it is fuel controlled. If Fire fighters open a ventilation path what effects will it have on the fire?
A. Fire will intensify leading to a possible flashover situation.
B. initially slow it’s progress to flashover, but if not quickly controlled it may grow larger.
C. it will remove smoke to clear visibility and allow fire attack crews to locate the fire quickly
D. the sudden air supply can lead to a rapid fire event such as backdraft or flashover.
B. initially slow it’s progress to flashover, but if not quickly controlled it may grow larger.
Ch. 4 Which of these is the substance of most concern to firefighters? A. Hydrogen cyanide B. Hydrogen chloride C. Acrolein D. Nitrogen oxides
D. Nitrogen dioxides
Ch. 4 pg. 102 \_\_\_\_\_\_\_ could make the firefighters less capable of reacting to and escaping from any dangerous situation that might suddenly develop. A. mental exhaustion B. physical exhaustion C. Fatigue D. Situational awareness
C. Fatigue
mental exhaustion- miss subtle danger signs of collapse
physical exhaustion - reduces strength and coordination.
Ch. 4 pg 103 A firefighter that does not thoroughly clean their turnouts, gloves, helmets and any other contaminated gear has what level of exposure? A. Primary exposure B. Secondary exposure C. Residual exposure D. long term exposure
C. residual exposure
Ch. 14 pg. 411 Fire crews may use the freight elevators when authorized by whom: A. Incident commander B. Officer on the Fire floor C. Safety officer D. Lobby control officer
B. officer on the fire floor.
411 also says when deemed safe by incident commander
