1. What is the primary function of the PASS device in fire safety equipment?
To measure temperature
To detect smoke
To extinguish fires
To provide an audible warning
2. Explain the relationship between the number of rope segments supporting
the load and the mechanical advantage in a block and tackle system with the
anchor knot at the anchor.
The mechanical advantage is determined by the ratio of pulley sizes,
not the number of rope segments.
Each rope segment supporting the load effectively shares the
weight, increasing the mechanical advantage by a factor equal to
the number of segments.
The mechanical advantage is only affected by the friction within the
pulleys.
The number of rope segments has no impact on the mechanical
advantage when the anchor knot is at the anchor.
The mechanical advantage is inversely proportional to the number of
rope segments; more segments decrease the advantage.
3. Which ladder length is best for a third-story roof?
- 35 to 40 ft
- 40 to 50 ft
, - 26 to 30 ft
- 30 to 35 ft
4. What is the volume of a cylinder with a diameter of 9 m and a height of 15 m?
1,590.4 cubic metres
954.3 cubic metres
106.0 cubic metres
238.6 cubic metres
5. What is the formula to calculate the area of a circle?
A = πr²
A = r²/2
A = 2πr
A = πd
6. In a scenario where a firefighter has activated the PASS device
unintentionally, what steps should be taken to disarm it, and why is this
important in a high-stress environment?
The firefighter should remove the PASS device entirely from the SCBA
unit.
The firefighter should call for assistance to manually disarm the
device.
The firefighter should turn off the SCBA unit or refill the tank above
500 psi to disarm the PASS device, preventing unnecessary alerts
and maintaining operational focus.
The firefighter should ignore the device and continue working, as it
will reset automatically.
,7. Which organs are primarily affected by smoke inhalation during a fire
incident?
Lungs and respiratory tract
Kidneys and urinary system
Heart and circulatory system
Skin and epidermis
8. A pulley has two supporting strands. In order for it to lift a load 1 meter, the
person pulling will have to pull a distance of
2 m.
m.
4 m.
1 m.
9. In a scenario where a victim is stranded on a rock in swift water, which steps
would you prioritize from the swift water rescue procedure, and why?
talk, reach, throw
throw, row, assist
go, swim, dive
row, go, helo
10. What is the mechanical advantage of a Block and Tackle system when the
anchor knot is positioned at the load?
It is characterized by the weight of the load being lifted.
It is characterized by the length of the rope used.
, It is characterized by the number of rope segments supporting the
load.
It is characterized by the angle of the pulley.
11. If a mechanical system operates at a constant torque but the speed is
doubled, what happens to the power output?
The power output quadruples.
The power output doubles.
The power output remains the same.
The power output decreases by half.
12. If an entrant fails to probe the ground before entering a body of water, what
potential risks could they face?
Hypothermia from cold water.
Injury from hidden obstacles or unstable ground.
Dehydration from prolonged exposure.
Drowning due to strong currents.
13. If a patient requires 150 mcg of Narc fentanyl, how many mL would you need
to administer via IV?
2 mL
13.5 mL
3 mL
4 mL
