CORROSION PREVENTION CONTROL (CPC)
The DSB System has a total service life of twenty years which allows for extended periods
of operation in a corrosive environment. A corrosive environment includes exposure to high
humidity, salt spray, road-deicing chemicals, gravel, and atmospheric contamination. No action
beyond normal washing and repair of damaged areas is necessary to control corrosion. However,
it is recommended that to prevent moisture accumulation during periods of low use, the launcher
should be periodically exercised to allow water to drain and hinge joints and cylinders to be
Strong detergents should not be used on the bridge or the launch beam modules as these
can be corrosive to aluminium. Particular care should be taken to ensure that all traces of salt
spray and deicing chemicals are removed from exposed areas of aluminum, particularly in the jaw
bores of the launch beam modules.
