Just a further point :-
He said that in Vietnam , there was a guy on fire and in their panic, they threw a bag of flour all over him to put the fire out...Well,
Flour, coal dust, house dust, can explode or cause a fireball when exposed to a direct flame so the above comment seems pretty exaggerated.
