Correct answer: DRemove from exposure and give high-flow oxygen to symptomatic casualties

Pulse oximetry cannot distinguish oxyhaemoglobin from carboxyhaemoglobin, so a normal reading does not exclude carbon monoxide poisoning. Removal from exposure and high-flow oxygen are immediate priorities. Scene safety and multi-agency control are essential to prevent further casualties.
