SPECIFIC FIRE BEHAVIOUR:

Specific learning outcome:

Deep flaming may result from elevated rates of spread, wind changes or fire channelling.

Topic:

How deep flaming may form.

Operational Awareness for Advanced Firefighters & Fire Behaviour Analysts


Deep flaming may form, at times of elevated FDI, when any of the following occur:
  • The rate of spread of a headfire is extreme.
  • A wind change, making a flank the new, extremely broad headfire.
  • Fuel moisture content approaches zero with frequent, rapdily coalescing spotting.
  • Fire channelling.
Deep flaming means that the depth of the flaming zone is of the same scale as its width. Any observation of this must lead to issuing watchouts (Deep flaming) or Red Flag Warnings (Conditions Conducive to plume-driven fire).
