are not constrained to vacuum conditions as were their predecessors. In the vicinity of the surface, there are extreme solute concentration gradients involving colloids, ions and organics, which, though difficult to access, are the focus for important interfacial events. The conventional consideration
Minimize Dust Explosion Hazards
insidious, and potentially more dangerous, than vapor blow-ups. As fluids, flammable gases mix and diffuse through the atmosphere more or less homogeneously, through predictable concentration gradients. As a result, vapor explosions tend to involve a single, relatively localized blast. Because

into it. This property is expressed as the moisture-vapor-transmission rate (MVTR). The greater concentration gradient provides a stronger driving force for the MVT, thus creating a wicking action in the material.
