A blasting method of blasting an explosive device at least containing an explosive and a chemical agent in a sealed pressure vessel that prevents soot generation during blasting and improves an efficiency of decomposing the chemical agent. First, a transported chemical bomb (explosive)is placed and sealed in a blasting chamber (pressure vessel)The blasting chamberis then brought into a reduced-pressure or vacuum state by aspiration of the air therein by using a vacuum pumpand oxygen is supplied through an injection portinto the blasting chamberto a pressure of 15 to 30% of atmospheric pressure. The chemical bombis then blasted, as it is ignited by an ignition device not shown in the Figure.
