Question 1

Crews arrive at a closed workshop with hot, smoke-stained windows. Little flame is visible, smoke pulses from a door seam, and air whistles inward when the door cracks open. The department bulletin defines flashover as a heat-driven near-simultaneous ignition of exposed combustibles, typically preceded by rapidly increasing heat, rollover, and a lowering neutral plane. It defines backdraft as rapid combustion after oxygen enters a hot, oxygen-depleted, fuel-rich compartment, with indicators such as pulsing smoke, darkened windows, and inward air movement. The conditions most strongly indicate:

Accepted Answer

A backdraft-prone, ventilation-limited compartment

Answer

A growth-stage fire approaching flashover

Answer

A fully developed fire with unrestricted oxygen

Answer

An incipient fire with limited heat release

Question 2

A product data sheet lists a specific gravity of 0.82 and a vapor density of 2.6. Its interpretation key says an insoluble liquid with a specific gravity below 1 tends to float on water, while one above 1 tends to sink. Vapor density below 1 indicates a tendency to rise relative to air; above 1 indicates a tendency to collect in low areas, although wind and heat can alter that behavior. If the product leaks beside an open drainage channel, the most likely initial pattern is:

Accepted Answer

The liquid will float, and the vapor will tend to collect in low areas.

Answer

The liquid will sink, and the vapor will tend to rise.

Answer

Both the liquid and vapor will remain concentrated at the release point.

Answer

The liquid will sink, and the vapor will tend to collect in low areas.

Question 3

At a mass-casualty scene, a patient cannot walk because of an ankle injury, breathes 24 times per minute, has a palpable radial pulse, and follows simple commands. The START card tags walking patients Minor; it tags patients Immediate for a respiratory rate above 30, absent radial pulse or capillary refill above 2 seconds, inability to follow commands, or breathing that begins only after airway repositioning. A nonambulatory patient whose respiration, perfusion, and mental status stay within those limits is Delayed. The appropriate tag is:

Accepted Answer

Delayed

Answer

Immediate

Answer

Minor

Answer

Deceased/expectant

Question 4

During a warehouse inspection, crews find masonry exterior walls, exposed heavy-timber columns and beams, and a stair door held open by a wooden wedge. The inspection standard classifies noncombustible exterior walls with combustible interior elements as Type III, and noncombustible exterior walls with large-dimension heavy-timber members as Type IV. A fire door may be held open only by an approved device that releases automatically. The correct inspection finding is:

Accepted Answer

Type IV construction; the wedged fire door violates the standard.

Answer

Type III construction; the wedged fire door is acceptable during occupancy.

Answer

Type IV construction; any hold-open method is acceptable if the corridor is clear.

Answer

Type V construction; the door is compliant because masonry walls are present.

Question 5

A portable fan will not start. After disconnecting power, the operator finds its intake guard packed with debris, and the manual authorizes the operator to clean that guard. The maintenance procedure calls for verifying the symptom, making the equipment safe, inspecting simple causes, consulting the manual, isolating the fault, repairing only within authorization, performing a safe operational test, and documenting the result. The operator should next:

Accepted Answer

Clean the guard, reassemble the fan, test it safely, and document the result.

Answer

Remove the fan from service and send it to a technician without further troubleshooting.

Answer

Bypass the intake guard and run the fan briefly to confirm airflow.

Answer

Replace the motor because a no-start complaint proves motor failure.

Question 6

Twelve search crews-three on each of four floors-currently report directly to the incident commander. The incident plan sets an acceptable span of control at 3 to 7 direct reports, requires unity of command, assigns divisions geographically, and assigns groups functionally. All crews must remain working. The structure that best restores span of control while preserving geographic accountability is to:

Accepted Answer

Create four floor divisions, each supervising three crews.

Answer

Create one search group with all 12 crews reporting to it.

Answer

Move six crews to staging and retain six direct reports.

Answer

Create 12 one-crew divisions reporting directly to command.

Question 7

During a preentry SCBA check, the wearer cannot obtain a facepiece seal because the edge of the protective hood lies across the sealing surface. The cylinder is full and the rest of the unit passes inspection. Because the readiness rule requires a successful seal check before entry, the crew should:

Accepted Answer

Move the hood edge, reseat the facepiece, and repeat the seal check.

Answer

Replace the entire SCBA even if the seal succeeds after the hood is corrected.

Answer

Enter after tightening the shoulder straps because cylinder pressure is normal.

Answer

Rely on positive pressure to compensate for the opening at the seal.

Question 8

In an ideal compound gear train, Gear A has 12 teeth and drives Gear B with 36 teeth. Gear B shares a shaft with Gear C, which has 10 teeth and drives Gear D with 20 teeth. Gear A turns clockwise at 600 rpm. For each stage, the ratio equals driven teeth divided by driver teeth; stage ratios multiply; output speed equals input speed divided by the overall ratio. Each external mesh reverses direction, while gears on the same shaft turn together. What is Gear D's motion?

Accepted Answer

100 rpm clockwise

Answer

100 rpm counterclockwise

Answer

200 rpm clockwise

Answer

300 rpm counterclockwise

Question 9

A motor must drive a second shaft in the opposite rotational direction without changing either pulley's diameter. An open belt turns the driven pulley in the same direction as the driver; a crossed belt turns it in the opposite direction. A tensioning idler in an otherwise open path does not change that relationship. Which modification directly produces the required reversal?

Accepted Answer

Cross the belt between the driver and driven pulleys.

Answer

Install a longer open belt.

Answer

Increase both pulley diameters equally.

Answer

Add a tensioner while retaining the open belt path.

Question 10

An ideal block-and-tackle is re-rigged so that one additional rope segment directly supports the moving load. In an ideal pulley system, increasing the number of supporting segments increases mechanical advantage. What tradeoff should the crew expect for the same load movement?

Accepted Answer

Less effort and more rope travel

Answer

More effort and less rope travel

Answer

Less effort with no change in rope travel

Answer

No change in effort because only fixed pulleys affect mechanical advantage
