I`d like to know whether or not any of that flash fire caused facial burns which, depending on the severity and degree of swelling to the nose and mouth +/- smoke or fume inhalation (depending upon the accelerant) could be a more serious problem than a second degree burn to the hand (although the palm is considered a higher degree of importance even with first degree burns). Additionally, if the accelerant was petroleum based rather than alcohol, this becomes a biohazard situation with the petroleum being the hazard (fumes and liquid on the skin and inhaled).
of course I always read more into scenarios than actually appears on paper so sorry if I`m making things more complicated than need be.
In the dim lighting, I`d use other signs of the person`s presentation and assume shock is present. Skin colour is helpful, yes, but it`s one of those things that can be very misleading. I`ve seen men with perfect skin colour who are having a heart attack right in front of me. Their pain and anxiousness was more indicitive of a serious situation. I agree with Kaellyn, look for pulses and other signs of circulation, mentation and just presume some degree of shock (especially in the dark).
