The answer

James Robert Bolton answered on January 31, 1998

The burning of sulfur releases sulfur dioxide in the following reaction: S + O2 ---> SO2 SO2 is a pungent smelling gas that is VERY DAMAGING to lung tissue. The reason is that on contact with water, it forms sulfurous acid by the reaction: SO2 + H2O ---> H2SO3 So if you have inhaled a large amount of SO2, then you should definitely go to see your doctor or an emergency ward!
