Live Fire in 104-Degree Heat: Modify or Stop?
You are the lead instructor for a live-fire training evolution in an acquired two-story house. There are 22 students, 6 instructors, and 2 safety officers; the plan calls for three burn evolutions per crew between 0900 and 1500. The forecast is 96°F with a heat index of 104°F. The structure has been inspected and permits are posted. You have 18 SCBA cylinders for 22 students plus instructors, and the fill station can refill 8 cylinders per hour. Water supply is a hydrant rated at 800 gpm, with a 1,000-gallon tanker as backup. One student mentions at rehab that they took a new blood pressure medication this morning but says they feel fine. A company officer asks to add a fourth evolution because the crew needs the reps. Two instructors are also scheduled to work the next shift at 0700. The burn plan was approved by the chief, and the safety officer has not raised an objection.
1. Identify the risk factors and decide whether to proceed, modify, or stop the evolution. Justify your decision.

Reasoning approach
The plan as written should not proceed unchanged. The heat index of 104°F is a serious cumulative stressor, especially with students in full PPE and three evolutions. The SCBA inventory is tight: 18 cylinders for 22 students plus instructors is already below one cylinder per participant, and the fill station can only replace 8 per hour. That creates pressure to reuse cylinders or shorten rehab, both of which are unsafe. Two instructors working a 0700 shift the next day adds fatigue risk that may not be visible during the evolution.
The student on new blood pressure medication is a medical clearance issue, not a judgment call for the lead instructor. The student should be removed from the evolution until cleared by the department's medical authority. Do not accept feel fine as clearance.
Modify rather than cancel if the training value can be preserved safely: reduce to two evolutions per crew, extend rehab, add cooling and medical monitoring, secure additional cylinders or reduce the number of students per rotation, and set objective stop criteria for heat index, cylinder supply, or student symptoms. Deny the fourth evolution. Document the decision and the rationale. If the safety officer disagrees, escalate before ignition; do not proceed on silence alone.
2. What must be documented before, during, and after the evolution, and how would you handle the student's medication disclosure?

Reasoning approach
Before ignition, document the approved burn plan, permits, site inspection, safety briefing, attendance, instructor and safety officer assignments, student medical screening, SCBA cylinder inventory, water supply, and the rehab plan. Confirm that all participants meet the department's medical and training prerequisites.
During the evolution, record crew assignments, times in and out, cylinder use, rehab entry and exit, vital signs if the department's protocol requires them, safety officer observations, and any stop or modification. Record the actual number of evolutions, not the planned number.
After the evolution, document the critique, injuries or symptoms, exposure reports, equipment damage, cylinder refill status, and corrective actions. Preserve the records according to the department's retention policy.
For the medication disclosure, treat it as confidential medical information. Do not announce it to the crew. Tell the student that a new medication requires medical clearance before participating in live fire, refer the student to the department's medical authority, and document only the fitness-for-duty decision, not the diagnosis or medication. If the student is cleared later, record the clearance. If not, document the exclusion and the reason at the level the policy allows.
3. How would you respond to the company officer who wants a fourth evolution?

Reasoning approach
Acknowledge the legitimate goal: the crew needs repetitions. Then explain why the fourth evolution is not the way to get them today. The limiting factors are cumulative heat exposure, cylinder supply, instructor fatigue, and rehab time, not willingness. Adding an evolution increases risk for the whole group, not just that crew.
Offer alternatives that preserve training value: a dry walk-through of the same evolution with door control and radio benchmarks, a tabletop review of the crew's performance, video review if available, or a scheduled additional session on another day with adequate cylinders and cooler conditions. If the crew specifically needs line advancement practice, use a non-fire smokehouse or a dry evolution after rehab.
Do not make it personal or question the officer's judgment. Frame the decision as a safety and resource limit you are responsible for enforcing. Ask the safety officer to confirm the stop or modification in the documentation. If the officer continues to push, escalate to the chief before ignition rather than argue at the site. The decision should be recorded so the rationale is clear later.
