Missing Firefighter After PAR at a Big-Box Store Fire
At 10:05, a two-alarm fire burns in a 120,000-square-foot big-box store. Seventeen firefighters entered through the main entrance. After 14 minutes, the accountability officer conducts a personnel accountability report (PAR) and finds 16 personnel checked in; one firefighter is missing. The missing member was last seen on aisle 12 near a furniture display. A four-person rapid intervention team (RIT) was established, but two of its members were pulled to reinforce fire attack eight minutes ago. Low-air alarms are audible in the background, and the fireground channel is overloaded with routine traffic. The missing firefighter's PASS device has not been heard. Smoke is banked down to about four feet, and the store has a complex aisle layout with high-rack storage. The IC asks the ISO whether to order an immediate evacuation or deploy the remaining RIT members.
1. Identify the immediate actions the ISO should recommend for the missing firefighter and the RIT.

Mayday and rescue actions. The missing firefighter is a life-safety emergency. The IC, not the ISO, should declare the Mayday and assign a rescue group; the ISO's job is to make sure the rescue is not improvised. Immediate actions: transmit a clear Mayday with the last known location, switch fireground operations to a separate tactical channel, conduct a PAR, stop all nonessential radio traffic, and hold additional entry. The RIT must be restored to full strength before it enters; pulling two RIT members into fire attack was the root problem. The rescue group should take a thermal imager, a protecting hoseline, forcible-entry tools, and a search rope, and should search on the right- or left-hand wall from the last known location.
Accountability. The accountability officer should reconcile the passport board, entry times, SCBA cylinder times, and crew assignments. The missing member was last seen on aisle 12, so the search should start there and work toward the nearest exit. The ISO should verify that the rescue group has a separate radio channel or talk group and that the RIT has a dedicated safety officer if the incident is large enough.
Command and safety. Do not send untrained personnel into the structure, and do not let the rescue become a second Mayday. The ISO should monitor air, smoke conditions, and structural stability, and recommend evacuation if the rescue cannot be completed safely. After the rescue, preserve the accountability records and radio log for the post-incident analysis.
2. Should the IC order an immediate evacuation of all interior crews? Explain the trade-offs.

An immediate evacuation is a defensible option because the RIT is degraded, one firefighter is unaccounted for, and the store is large with high-rack storage. Evacuation clears the structure for a focused rescue, reduces radio traffic, and lowers the chance of a second missing member. The trade-off is that evacuation takes time, may push the missing firefighter deeper if he is still mobile, and may remove protecting lines that the rescue group needs. The ISO should frame the choice as a rescue-mode decision, not a routine firefighting decision.
A better recommendation may be a partial evacuation: withdraw crews not assigned to rescue, keep one protecting line for the rescue group, and restore a full RIT before entry. The IC should announce the mode clearly, conduct another PAR after evacuation, and keep the rescue group on a separate channel. The ISO should monitor the rescue group's air and the structural conditions, and should recommend full evacuation if the rescue cannot proceed safely. Document the decision, the time, and the PAR results. The post-incident review should focus on why the RIT was stripped and how the accountability system failed to flag it earlier.
