Decommissioning or
Zeroisation
It is a best practice to purge data before disposing
of any device containing data. Guidelines for
decommissioning are provided in NIST SP 800-
88. Eaton recommends that products containing
embedded flash memory be securely destroyed to
ensure data is unrecoverable.

Embedded Flash Memory on Boards and
Devices
Eaton recommends the following
methods for disposing of motherboards,
peripheral cards such as network adapters, or
any other adapter containing non-volatile flash
memory.
•
Clear:
If supported by the device, reset the
state to original factory settings.
•
Purge:
If the flash memory can be easily
identified and removed from the board, the
flash memory may be destroyed independently
of the board that contained the flash memory.
Otherwise, the whole board should be
destroyed.
•
Destroy:
Shred, disintegrate, pulverize, or
Incinerate by burning the device in a licensed
incinerator.
