blacking out
n.— «We haven’t been attacking the fire from the front, but controlling it from the flanks to stop it spreading.…The process was called “blacking out” which involved mopping up where the fire had burned already, dousing left-over flames and putting out smouldering embers.» —“Ruapehu firefighters feel the heat” by Andrew Koubaridis Wanganui Chronicle (New Zealand) Jan. 25, 2007.
