I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">save from disaster</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for rescue that I've seen before include "Extricate" , "Being presumptuous" , "gets one out of a tight corner" , "Set free from harm and evil" , "saving" .)
