APPENDIX B
CORROSION AREAS
B-1 .
General.
a. This appendix provides recommended vehicle wash intervals based on the severity of the corrosive
environment. Shaded maps show major U.S. Army vehicle concentrations in the following locations:
(1) Alaska.
(2) Continental United States (CONUS).
(3) Federal Republic of Germany (FRG).
(4) Hawaii.
(5) Panama.
(6) Puerto Rico.
(7) Republic of Korea (ROK).
b. Intervals listed in Table B-1 are the minimum recommended wash intervals. These intervals should be
adjusted with regard to availability of vehicles, personnel, and washrack facilities. Washrack facilities may have
seasonal limitations. However, in an effort to control and prevent corrosion, measures must be taken to keep
vehicles as free of corrosive contaminants as possible,
B-2. Wash Intervals/Corrosion Areas.
Table B-1 provides recommended vehicle wash intervals based on the severity of the corrosive environment in
which they operate. The severity of the corrosion areas are indicated by the maps that follow Table B-1.
NOTE
Highly corrosive environments, as indicated by the maps, include "severe" and "ex-
tremely severe" corrosive regions. A highly corrosive environment does not refer
only to areas where the use of road salts or other chemical de-icers is common; high
humidity areas, andlor areas with a high concentration of salt in the air are also
considered to be highly corrosive.
