Size-Up at 418 Maple Street: Details That Contradict the Story
At 02:14 you arrive first due at 418 Maple Street: a two-story wood-frame dwelling, about 60 by 40 feet, with a pitched asphalt-shingle roof. Smoke pushes from two second-floor windows on Side A; the left window shows a dull orange glow at the sill. The front door on Side A stands open about six inches. A sedan sits in the driveway with a warm hood, and a bicycle lies on the front walk. A dog barks in the fenced rear yard on Side C. A child's car seat is visible through the sedan's rear window. A neighbor says the house has been vacant since the Hendersons moved out in March. On Side B, the electric meter is spinning and the gas meter dial shows no movement; the service mast is intact, with lines from the pole attached.
1. List at least four observed details that conflict with the neighbor's 'vacant since March' claim, and explain the tactical difference each one makes.

Conflicting details and why they matter:
- Warm hood on the sedan. Recent engine heat means the car was driven recently - someone was here, plausibly minutes ago. Tactical effect: search priority rises; the occupant may be inside or may have just left.
- Bicycle on the front walk. Suggests a resident who travels locally and is likely nearby. Supports a primary search.
- Child's car seat in the sedan. Indicates a child in the household. Tactical effect: search for a child is the highest-consequence action on scene; request EMS early.
- Dog barking in the fenced rear yard on Side C. A dog in a fenced yard means someone has been feeding and containing it - occupancy, not vacancy. Tactical effect: a pet is a bite hazard for a Side C crew, and the fence limits access and egress.
- Electric meter spinning on Side B. Active current draw means either occupancy or energized circuits serving something. Tactical effect: energized service is a shock hazard; utilities need control before exterior stream work near the service.
- Front door open about six inches. Consistent with a hurried exit - and an open door is a flow path that feeds the fire.
The gas meter showing no movement is not a contradiction: gas may simply be shut off or no gas appliance running. Report it as an observation, not as evidence of vacancy.
2. Given the smoke and glow conditions, what is the likely fire location and floor, and what does the door's position suggest? State the limits of your inference.

Fire location: second floor, Side A, left-hand room.
- Smoke pushing from two second-floor windows on Side A means the second floor is pressurized and the fire has been producing smoke long enough to build that pressure.
- A dull orange glow at the sill of the left window indicates visible flame behind that window, low in the opening. Glow at the sill rather than the top suggests burning near the floor level of that room or a room fully involved behind it.
- 'Dull' rather than bright suggests the fire has not fully vented that window; expect a rapid change if the glass fails or a vent is taken.
Door open about six inches: consistent with an occupant leaving in a hurry, or a door not fully latched. It also means the stairwell may already be receiving smoke. It is not evidence of forced entry, and it should not be assumed to be a viable entry point for a search crew without checking conditions inside.
Limits: this is a single-point observation from Side A. The glow could be a reflection; the fire may extend to the attic via the pitched roof; the extent on Side C is unknown because no 360 has been completed. Two windows showing smoke does not mean only two rooms are involved. Report the inference as a working assumption and confirm with a 360 and interior conditions.
3. What three pieces of information do you pass to the incoming battalion chief first, and why those three?
Read the worked answer
- Possible occupants, despite the vacancy report. The warm hood, bicycle, car seat, dog, and spinning meter all point to occupancy. This is first because it drives the search priority, the number of crews committed, and the EMS request. A 'vacant' assumption kills people.
- Fire location and conditions: second floor, Side A, smoke pushing from two windows with visible glow at the left sill. This drives line placement (stretch to the second floor, back up the stairs), ventilation timing, and whether the roof is a candidate for vertical ventilation.
- Hazards and unknowns: energized electrical service on Side B with the mast intact, a dog in the fenced Side C yard, and no 360 completed. This drives utility control, crew assignment on Side C, and tells the chief what you do not yet know.
Why these three: they answer the chief's decision questions - who might be inside, where the fire is and what it is doing, and what will hurt my people. Address and construction are already on the ticket; these are the facts that change the plan.
Keep it short and declarative, and state the source of the vacancy claim so the chief can weigh it rather than inherit it.
