Identification
Radioactive self-luminous sources are identified by means of radioactive warning labels (as
above). These labels should not be defaced or removed, and should be replaced immediately
when necessary. Refer to the local RPO or the ACALA RPO for instructions on handling, stor-
age, or disposal.
Storage
When radioactively illuminated instruments are defective, notify unit maintenance. These items
must be placed in a plastic bag (item 5, Appx D) and packaged in the shipping container. Spare
equipment must be stored in the shipping container, as received, until installed on the weapon.
Storage of these items is recommended to be in an outdoor shed-type storage or unoccupied
building.
