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.

Abstract:
A refueling boom is described. The refueling boom includes a non-telescoping portion configured to be coupled to a fuel tanker vehicle and a telescoping portion that is extendable and retractable relative to the non-telescoping portion. The telescoping portion includes a fuel nozzle. The refueling boom also includes a wireless communication system operable to enable wireless communication between a first location of the telescoping portion to a second location of the non-telescoping portion. The refueling boom also includes a control unit coupled to the telescoping portion. The control unit is operable to send first information to the fuel tanker vehicle via the wireless communication system and to receive second information from the fuel tanker vehicle via the wireless communication system.
