During the tour-start SCBA check, a cylinder reads 96% full and the regulator and bypass function normally, but the PASS device will not sound a full alarm. A spare SCBA is available. What should the company officer direct?
Correct answer: D - Remove the SCBA, issue the spare, notify the responsible support unit, and record the defect
While reviewing the company journal, a lieutenant discovers that an entry lists Engine 99 instead of Engine 59. The event time and actions are otherwise accurate. How should the record be corrected?
Correct answer: B - Strike through the wrong number once, enter the correction, and identify and date the change as required
An interior engine company reports that its attack line has suddenly lost pressure while members are operating above the fire. No member is trapped or personally declaring distress. Which radio classification should the officer use?
Correct answer: D - URGENT; the water loss immediately affects operational safety
A closed apartment has smoke-stained windows, pulsing smoke at the door seams, high heat, and little visible flame. A charged line is not yet in position. Which interpretation and action are best?
Correct answer: A - Ventilation-controlled decay with backdraft potential; control the door until cooling and attack are coordinated
Fire is on the top floor of a Type III ordinary building. Smoke is pushing from the cornice, and heat is increasing above rooms that show little damage. Which paired concern should drive the next size-up?
Correct answer: C - Cockloft extension through combustible voids and parapet or masonry collapse
At a growing incident, the incident commander is directly supervising nine companies assigned across three floors and the roof. Radio traffic is becoming difficult to track. The best command adjustment is to:
Correct answer: B - Create divisions and groups so supervisors each manage three to seven resources
A 12th-floor apartment fire requires a standpipe stretch. All outlets are operable. Which setup is appropriate?
Correct answer: A - Connect on the 11th floor; use 2½-inch hose with a 1⅛-inch smooth-bore tip at 50 psi
A 2½-inch line is operating five floors above the pump. Required nozzle pressure is 50 psi, total friction loss is 35 psi, and appliance loss is 10 psi. Using the 5-psi-per-floor approximation, which initial pump action is correct?
Correct answer: C - Set 120 psi and increase flow gradually to avoid water hammer
A worker is unconscious inside a tank reached through a narrow manway. A meter at the opening reads 18.2% oxygen. A firefighter in structural PPE offers to climb in immediately. The officer should first:
Correct answer: C - Establish zones, monitor and ventilate, then deploy a trained team with retrieval and respiratory protection
A ladder team enters a bedroom through a window for VEIS. Heat and smoke are pushing under the open hallway door, and the room remains tenable. Before conducting the full room search, the team should:
