  • Patent number: 7497165
    Abstract: 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) 100 is placed and sealed in a blasting chamber (pressure vessel) 10. The blasting chamber 10 is then brought into a reduced-pressure or vacuum state by aspiration of the air therein by using a vacuum pump 13a and oxygen is supplied through an injection port 12 into the blasting chamber 10 to a pressure of 15 to 30% of atmospheric pressure. The chemical bomb 100 is then blasted, as it is ignited by an ignition device not shown in the Figure.
