NFSI Information Ordering Application Questions and Answers — Questions and Answers
Question 1: A firefighter must write a narrative for an incident report. The following sentences describe the events. What is the correct chronological and logical order for these sentences? 1. Upon arrival, crews observed light smoke coming from a second-floor window of a two-story residence. 2. Engine 1 was dispatched at 15:30 to a report of a possible structure fire. 3. The fire was declared under control at 15:55, and overhaul operations began. 4. A 1.75-inch attack line was advanced to the second floor, where a small fire in a bedroom was quickly extinguished.

- 2, 4, 1, 3
- 1, 4, 2, 3
Correct answer: 2, 1, 4, 3
Incident reports should tell a story in chronological order. The correct sequence is: Dispatch (2), Arrival Conditions (1), Actions Taken (4), and Outcome/Conclusion (3). This order logically presents the events as they unfolded.
Question 2: When responding to a motor vehicle accident on a highway, which of the following sequences of actions represents the correct priority of operations for the first-arriving fire unit? 1. Stabilize the involved vehicles. 2. Position the apparatus to protect the scene. 3. Establish a safe work area with traffic control devices. 4. Provide patient assessment and care.

- 2, 3, 1, 4 (Correct answer)
- 3, 2, 4, 1
Correct answer: 2, 3, 1, 4
The highest priority at any roadway incident is the safety of the responders and the public. The first-arriving unit must first position the apparatus to create a barrier (2). Then, a broader safe work area is established (3). Once the scene is secure, the vehicles are stabilized to prevent further movement or injury (1), and only then can responders safely access the patients to provide care (4).
Question 3: A firefighter is tasked with properly donning their Self-Contained Breathing Apparatus (SCBA). Arrange the following critical steps into the correct sequence. 1. Don the facepiece and check for a proper seal. 2. Fully open the cylinder valve and check the gauge readings. 3. Don the backpack assembly and tighten the straps. 4. Connect the regulator to the facepiece and begin breathing.
- 2, 3, 1, 4 (Correct answer)
- 1, 3, 2, 4
- 3, 2, 4, 1
- 2, 1, 3, 4
Correct answer: 2, 3, 1, 4
The correct and safest procedure is to first ensure the air supply is on and functioning by opening the valve and checking gauges (2). Next, the firefighter puts on the main harness assembly (3). Then, the facepiece is donned and a negative or positive pressure seal check is performed to ensure it is airtight (1). The final step is to connect the regulator and confirm the apparatus is delivering air (4).
Question 4: You are the first unit arriving at a suspected hazardous materials incident involving a leaking tank truck. What is the proper sequence of initial actions? 1. Identify the material using placards and the Emergency Response Guidebook (ERG). 2. Isolate the area and deny entry to the public. 3. Approach the scene from uphill and upwind. 4. Establish command and request additional resources.

- 2, 4, 3, 1
- 4, 1, 2, 3
- 3, 2, 4, 1 (Correct answer)
Correct answer: 3, 2, 4, 1
The absolute first priority when approaching a potential hazmat scene is responder safety, which means positioning the apparatus uphill and upwind to avoid any hazardous vapors or liquids (3). The next immediate action is to isolate the hazard area and prevent others from entering (2). With the scene initially secured, the officer should establish command and call for the necessary specialized teams and resources (4). Only after these safety and command steps are taken should an attempt be made to identify the material from a safe distance (1).
Question 5: Two firefighters are preparing to raise a 24-foot extension ladder to a second-story window using a beam raise. What is the correct order of the following general actions? 1. One firefighter 'foots' the ladder to prevent it from slipping while the other raises it. 2. The ladder is carried on its beam to the target location. 3. The halyard is untied and the fly section is extended to the proper height. 4. The ladder is raised from the ground to a vertical position against the building.
- 2, 1, 4, 3
- 4, 2, 1, 3
- 2, 4, 1, 3 (Correct answer)
- 1, 2, 4, 3
Correct answer: 2, 4, 1, 3
The logical flow of operations is to first transport the ladder to its point of use (2). From there, it is pivoted and raised into a vertical position against the structure (4). For safety, one firefighter must then foot the ladder at its base to prevent it from kicking out (1). Once the ladder is secure, the fly section can be safely extended to the desired height (3).
Question 6: A firefighter is performing the weekly maintenance check on a chainsaw. Place the following steps in the most logical and safe order. 1. Check the fuel and bar oil levels, and refill if necessary. 2. Start the saw to ensure it runs properly and the chain brake functions. 3. Disengage the chain brake and inspect the chain for proper tension and sharpness. 4. Ensure the saw is off, and clean debris from the cooling fins, air filter, and chain cover.
- 1, 4, 3, 2
- 4, 3, 1, 2 (Correct answer)
- 2, 4, 1, 3
- 3, 1, 4, 2
Correct answer: 4, 3, 1, 2
Safety dictates that mechanical inspections and cleaning should be done while the tool is off. Therefore, the first step is to clean the saw (4). Next, with the saw still off, the firefighter can safely handle the chain to check its tension and condition (3). After the mechanical checks are complete, fluids can be topped off (1). The final step is to start the saw to functionally test its operation and safety features like the chain brake (2).
