ABSTRACT:
A chemical exposure indication device is disclosed. The device is removably attachable to a structure and includes a substrate having a first surface and a second surface and an indicating layer overlying the first substrate surface. The indicating layer includes a coating material that is chemically reactive with a pre-determined chemical compound that is known to degrade the structure. When the coating material is exposed to that corrosive compound in a pre-determined level associated with degradation of a metallic structure, the coating material provides a visual indication of the presence of the corrosive compound.
