 FACTSHEET ON EXPLOSIVE PRECURSORS

Explosive precursors are oxidizing agents with legitimate industrial usage and are essentially safe in their original properties. However under certain circumstances, either when reacted in certain controlled conditions or mixed with other products, these could be converted into explosives and have the potential to be used as hazardous materials for terrorist purposes. 15 precursors that are widely used for research, industrial and agricultural purposes have been identified for control under the Arms and Explosives Act.
