FCTC Situational Judgment Scenarios 2 — Questions and Answers
Question 1: You are the first arriving firefighter at a reported structure fire. Your officer orders you to advance a hose line to the front door. As you approach, you notice the front door is slightly open and smoke is pushing out at ceiling level. What is the best immediate action?
- Open the door fully and enter immediately
- Stay low, control the door, and wait for water before opening further (Correct answer)
- Back away and call for additional resources only
- Remove your SCBA to communicate with the officer
Correct answer: Stay low, control the door, and wait for water before opening further
Staying low, controlling the door (not fully opening it), and waiting for water before opening protects against flashover and sudden fire intensification when air is introduced.
Smoke pushing at ceiling level from a partially open door indicates a hot, oxygen-limited fire — a potential backdraft or near-flashover condition. Fully opening the door rapidly introduces oxygen, which can cause explosive fire growth. The correct technique is to stay low (below the smoke layer), control the door by keeping it slightly open, and wait until water is flowing through the hose before opening the door. This limits air introduction until the attack line is ready to immediately apply water, controlling fire spread.
Question 2: During search operations in a smoke-filled room, you become disoriented and cannot locate the door you entered through. What is the correct action?
- Stand up to see above the smoke layer
- Call a Mayday immediately and activate your PASS device (Correct answer)
- Move quickly in any direction to find an exit
- Continue searching for victims before calling for help
Correct answer: Call a Mayday immediately and activate your PASS device
Being disoriented in a burning structure is an immediate life-safety emergency — a Mayday should be called immediately and the PASS device activated to alert rescuers to your location.
NFPA 1500 and standard firefighter survival training require that a Mayday be called the moment a firefighter recognizes a potentially life-threatening situation — including disorientation in a burning structure. Time is critical; earlier notification means more time for the RIT to locate and rescue you. Activating the PASS device provides an audible signal for rescuers. Standing up exposes you to superheated gases. Continuing to search puts both you and any victims at greater risk. Call Mayday first — always.
Question 3: You are operating a hose line inside a structure when you notice the smoke layer rapidly descending to floor level and the temperature increases dramatically. What fire behavior phenomenon is likely occurring and what should you do?
- Backdraft — close all doors and windows
- Flashover — immediately evacuate the room (Correct answer)
- Rollover — continue advancing but stay low
- Fire whirl — shelter in place
Correct answer: Flashover — immediately evacuate the room
A rapidly descending smoke layer and dramatic temperature increase are immediate warning signs of impending flashover — firefighters must evacuate immediately.
Descending smoke layer and rapid temperature rise are classic pre-flashover indicators. Flashover — when all combustibles in a room reach ignition temperature simultaneously — is immediately fatal. Firefighters must recognize these warning signs and evacuate the room before flashover occurs. Additional indicators include rollover (flames rolling at ceiling level), smoke turning from gray/white to black, and a feeling of intense radiant heat at floor level. There is no time to hesitate — immediate evacuation is the only appropriate response.
Question 4: Your crew is ordered to perform vertical ventilation on a burning structure. When you get to the roof, you notice the surface feels spongy under your feet in one area. What should you do?
- Continue working in that area because spongy roofs are normal
- Move away from that area and notify your officer immediately (Correct answer)
- Test the area by jumping on it
- Send a lighter crew member to work in that area
Correct answer: Move away from that area and notify your officer immediately
A spongy roof indicates structural compromise from fire damage — the roof may be close to collapse. Firefighters must immediately move to a solid area and notify command.
A spongy or soft feeling roof surface indicates that the roof structure below has been compromised by fire, heat, or water — it may be close to collapse. Firefighters performing vertical ventilation must continuously sound the roof and be alert to changes in surface feel. Immediate actions are: move to a structurally sound area, notify the officer and incident command, and reassess whether roof operations should continue. Roof collapse is one of the most common causes of firefighter fatality during structure fires.
Question 5: You arrive at a residential fire and observe a bystander at the scene who tells you their elderly neighbor is still inside. Your crew is not yet equipped for interior operations. What is the most appropriate action?
- Immediately enter the structure without PPE to attempt rescue
- Relay the information to your officer immediately and prepare for interior operations as quickly as safely possible (Correct answer)
- Ask the bystander to go back inside and help
- Wait until the fire is fully extinguished before attempting rescue
Correct answer: Relay the information to your officer immediately and prepare for interior operations as quickly as safely possible
Life safety information must immediately be relayed to the officer or incident commander, while the crew prepares for rapid entry. Entering without PPE risks the firefighter's life and reduces overall rescue capacity.
The firefighter's first obligation is to relay life safety information (victim location) to the officer or incident commander so it can be incorporated into the incident action plan. Simultaneously, the crew should prepare for interior operations as rapidly and safely as possible. Entering without PPE — even to save a life — is strongly discouraged because an injured or incapacitated firefighter creates a second victim and requires rescue resources that are then unavailable for the original victim. Rapid PPE donning is the correct balance of urgency and safety.
Question 6: During overhaul, a firefighter discovers a pile of papers and documents near the origin of the fire that appear undamaged. What is the correct action?
- Remove and dispose of them to complete overhaul
- Leave them undisturbed and notify the fire investigator or officer (Correct answer)
- Read them to understand the fire cause
- Move them to a dry area and resume overhaul
Correct answer: Leave them undisturbed and notify the fire investigator or officer
Potential evidence at or near the fire origin must be left undisturbed and reported to the fire investigator. Disturbing it could compromise the investigation.
Once overhaul is complete and the scene is secured, fire investigators may examine the area to determine cause and origin. Materials found near the point of origin — especially undamaged documents — may be critical evidence in determining whether the fire was accidental, incidental, or intentionally set. Firefighters must avoid touching, moving, or disturbing items that could be evidence. The correct procedure is to stop work in that specific area, protect the evidence from additional damage, and notify the officer or fire investigator immediately.
