CORROSION PREVENTION AND CONTROL
Corrosion prevention and control (CPC) of Army materiel is a continuing concern. It is important that any corrosion
problem with this item be reported so the problem can be corrected and improvements can be made to prevent the problem
in future items.
While corrosion is typically associated with the rusting of metals, it can also include deterioration of other materials, such
as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using an SF Form 368, Product Quality Deficiency Report. The
use of key words, such as “corrosion,” “rust,” “deterioration,” and “cracking” will ensure that the information is identified
as a CPC problem.
The form should be submitted to the address specified in DA PAM 738-750, Functional Users Manual
for the Army Maintenance Management System (TAMMS).
OZONE DEPLETING SUBSTANCES (ODS)
The continued use of ODS has been prohibited by Executive Order 12856 of 3 August 1993.
The use of ODS in the Army
IETMs is prohibited.
A listing of these substances will be provided by the acquiring activity.
DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE
