Final answer:
The statement D: Wood structural members may burn at approximately one inch every 45 minutes is not in accord with FDNY procedures.
Step-by-step explanation:
The correct answer to the question is D: Wood structural members may burn at approximately one inch every 45 minutes.
According to FDNY procedures, the rate at which wood structural members burn is not determined by a fixed time frame, such as one inch every 45 minutes. The rate at which wood burns depends on various factors such as the type of wood, moisture content, and oxygen supply. Therefore, statement D is not in accord with FDNY procedures.
