Metadata

This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.

If the file has been modified from its original state, some details may not fully reflect the modified file.

Short title	Air entrained into a plume increases volume while smoke travels to another room.
Image title	Section through two rooms. In the fire room, blue dashed arrows show air entrained into a widening plume above the fire; the plume becomes less dense with height (dilution) and its volume grows. It forms a hot gas layer under the ceiling, which flows under the door head into the adjacent room, where a person is exposed. A note states that lower concentration does not mean harmless smoke.
