Abstract: The invention relates to the use of a number of fluid filled compartments constructed in such a manner to mitigate the explosive effects of a small improvised explosive device (IED). This IED constructed to resemble an everyday electronic device such as a mobile phone. These fluids will be generally be but not limited to water and air. The invention known as IFIM will provide a scientific approach to the rendering safe of an IED by non explosively trained personnel. It will replace or support the current Least Risk Option which requires a level of technical skill and expertise to deal with an IED threat effectively. It will provide a quicker and more practical solution to the rendering safe of an IED threat till Bomb Disposal personnel can attend. The IFIM will be particularly effective when dealing with an IED threat on domestic aircraft.
