The department's full Structural Fire Control training day — the fire dynamics classroom that teaches members to read the building, followed by the live burn where they prove it. **4 hours minimum, up to 8 hours maximum**, depending on how many evolutions are run and how many crews rotate through; record the actual time span on the sign-in sheet. Draws on both department classes: reading smoke by volume/velocity/density/colour, flow path and door control, flashover and backdraft recognition, and what water does and where it has to land — then NFPA 1403 for the live portion, which is the controlling standard and to which the department live fire SOP defers. Covers the written pre-burn plan, two independent water sources, Class A fuel limits, the walk-through and two means of egress, every assigned position and its authority including the Safety Officer's power to halt any evolution regardless of rank, the pad's operational limits, NFPA 1584 medical monitoring, stop-work criteria, and the walk-out, after-action review and records.
