Inert Anti Probe

This simulated mail threat is an X-ray correct package bomb with an anti-open switch. It contains all the necessary P.I.E.S. (Power source, Initiator, Explosive, and Switch) components of an IED.

The PVC pipe bomb simulant is engineered to have the same density and effective atomic number (Zeff) as the real explosive threat. This type of switch is commonly referred to as a foil or anti-penetration switch. It uses kitchen cooking  foil to create contacts on the exterior of the box. A knife would close the circuit and function the device. To assist in classroom training, a picture of the internal components is displayed on the outer packaging with each of the P.I.E.S. components identified. This helps build image association without compromising the training aid.
