Plasticized flexible pyrotechnic material

A method of destroying a hazardous material in situ comprising the steps of:

• identifying a hazardous threat material at a location;
• providing a sheet or block of a plasticized flexible pyrotechnic material comprising a combination of:
• 50-99% by weight of a pyrotechnic composition comprising an inorganic oxidizer and metal or metal oxide powders;
• 1-50% by weight of a polymer plasticizer composition comprising one ore more low to mid molecular weight polyisobutylenes in the range of Mn from 500 to 1,300,000;
• and
• an iodine based biocide precursor,
• wherein said plasticized, flexible pyrotechnic material has a putty-like texture and is easily portioned and formed or molded into a desired shape for application to said hazardous threat material, and which burns at a temperature greater than 2000 degree C. and releases gaseous I2, for the destruction of hazardous bio-organisms, but does not detonate;
• selecting an appropriately sized portion of the plasticized flexible pyrotechnic material from the sheet or block;
• forming the portioned pyrotechnic material into a predetermined shape to cover the hazardous material in situ;
• igniting the portioned pyrotechnic material to destroy the hazardous material without detonation.
