I've just seen the pic in the Telegraph, yes he hasn't got any gloves on, nor for what its worth a helmet which may or may not give any fire protection anyway, but my main concern would be what is he breathing in?
If that pic makes you change your mind about not wearing gloves, does it also change your mind about not having an independant breathing apparatus in the aircraft!
I don't think it's a look of pain, just realisation that he is in the brown and smelly and needs to get out!
