into the black
What does into the black mean?
Retreating onto ground that has already burned — "the black" — as a survival tactic when a wildland fire blows up and overruns the line. The logic: fire needs fuel, the black has none left, so it's the safest place to be when everything else is about to ignite. One of the named safety zones in LCES (Lookouts, Communications, Escape routes, Safety zones) and a core concept in every wildland refresher.
Origin
US wildland firefighting doctrine; formalised in the post-1994 South Canyon Fire safety overhaul and embedded in NWCG training (the "10 Standard Firefighting Orders" and "18 Watch Out Situations").
