Smoke Showing on Arrival

You arrive first on a single-engine response at 02:10 to a two-story wood-frame house. Light smoke is pushing from a second-floor window; no flames visible. A woman on the lawn says her adult son is 'probably still inside, upstairs.' The front door is closed but warm to the touch. Your crew is three firefighters plus you. The next-due engine is estimated 6 minutes out; no ladder company dispatched yet. You have a 1.75-inch line pre-connected and full PPE with SCBA.

1. State your initial action priorities in order and justify the sequence.

Priority order:

  1. Establish command and a safety baseline - announce command, confirm all members are on air with PPE, and size up (smoke condition, construction, occupancy report).
  2. Transmit a follow-up message requesting a ladder company and confirming the reported occupant - the dispatcher needs the 'possible victim, second floor' detail now, not later.
  3. Advance the 1.75-inch line to the front door while a second member forces entry. A warm door with smoke above signals a fire inside; a charged line must be between the crew and the fire before anyone goes upstairs.
  4. Primary search coordinated with fire attack, not ahead of it, given a three-person crew.

Why this order: With only four personnel, the line and the search cannot be run as fully independent efforts. Securing a charged line first protects the search. The occupant report is time-critical and drives the upgrade request.

2. The mother insists you 'just go get him now' before the line is charged. How do you respond?

Read the worked answer

Acknowledge her directly and honestly - she needs to know she was heard - then explain the constraint in plain terms: 'We are going in, but we go in with water so we can reach him and come back out. Going up without a line puts everyone in that stairwell at risk, including him.'

Then act: keep the line advance moving at full speed, assign one member to keep her back from the door and get any details that matter (where upstairs, mobility, windows). Do not promise an outcome. Do not abandon the line to appease her. The judgment being tested is holding a sound tactical decision under emotional pressure while treating the family member with respect.

3. At the door, the smoke layer is banked down to about chest height in the stairwell. What does that change?

Read the worked answer

Banked-down smoke at chest height means the upper floor is likely well involved or the fire is below/adjacent and pushing heat and smoke into the stair. It changes the plan in three ways:

  • Stay low and stay on air - the neutral plane tells you where survivable space is; do not stand upright in the stair.
  • The search becomes a right-hand/left-hand oriented, touch-the-wall search with the line crew, because visibility will be near zero and the stair is the only way up.
  • Reassess the rescue vs. containment call. If the stair is untenable, the correct move may be to knock the fire back from the stairwell landing first, then search - and to tell command the occupant rescue is now a coordinated line-and-search, not a grab-and-go.

Communicate the changed condition to command and the incoming ladder company so they plan for a hot stairwell.
