Requests for approval must demonstrate that procedures, in accordance with the
component radiological health and safety regulations, are in place to track
and control inventory, to remove and replace devices at the end of their
useful life, to identify, evaluate, and decontaminate leaking or broken

is not available, long distances of wire and conduit make the installation of
conventional devices impractical, or where explosive environments exist).
