Abstract: This invention relates to any field where crafts (such as avionics) where inhabitants of volumes like passage compartments can be found where the area is subject to extreme conditions such as explosion, fire or other traumatic activity linked with a crash, and more specifically a pressurized dual-compartment canister or anti-trauma apparatus for the storage, mixing, and blast-release of a neutralizing chemical compound within the environment of the volume in a craft placed adjacent to the volume for the blast release of a quickly expanding and quickly retracting product.
