Abstract: A system for preventing explosions in a transported object which includes containers and packages with an imbedded port or window, a semipermeable cloth or filter layer that promotes air flow through natural physical and gaseous processes and access to internally generated trace particles and vapor plumes from contained explosive material, the integrity of which is protected by a mesh, grill, or woven matrix, and which may be impregnated with colorific luminescent chemicals that fluoresce, darken, or illuminate in the presence of explosive-containing material.
