Fire Patterns Flashcards
Any number of fire patterns created as a result of hot gases Rising above an individual fire.
Plume-generated
fire pattern that radiant heat forms in the hot gas layer during a fire before flashover these patterns are found when fires are extinguished before the fire has reached flashover.
Hot gas layer
Fire pattern that can vary widely in appearance and was created by ventilation introduced to a fire.
Ventilation-generated
Fire pattern left as a result of the way the fire was extinguished during fire suppression efforts.
Suppression-Generated
Full-room-involvement
fire pattern that occurs after flush over or after a fire has burned for long periods of time in which almost all vertical and horizontal services in the compartment will show signs of damage.
Fire pattern found on non-combustible surfaces where there has been direct contact with or intense radiant heat on the surface, the direct flame contact Burns away any accumulated sit or smoke deposits on the surface leaving demarcation lines.
Clean Burns
Fire pattern created when structural components such as wood studs or trim are exposed to Flame; sharp edges of the component are often burned away on the side of the component that faces the heat source.
Pointers or arrows
Pattern with no common shape in which the fire followed the path of available fuels.
Irregular patterns on floors
Saddle shaped fire pattern that is a result of fire burning downward to the floor surface above the joist.
Saddle Burns
Undamaged surface within an otherwise fire-damaged area. Possibly sure to shielding by large objects like furniture
Protected areas
