This section of the guide focuses on predicting the heat transfer from area exposure fire plumes to adjacent surfaces. Area exposure fires are burning objects or fuel located adjacent to or near the surface being heated. For certain scenarios, the local fire exposure may produce a more extreme exposure than the hot gas layer that develops in the area of consideration. Some examples are open parking garages, large warehouses, and bridges and overpasses. To analyze these scenarios, one needs to have knowledge of the incident heat flux levels produced by local fire plumes.
