WARNING
Cleanliness is imperative in maintaining and handling diving system components. All
tools and parts must be kept free of oil, grease, rust, or other contamination in
accordance with accepted Army diving cleaning procedures. Foreign substances within
an assembly could result in equipment failure and possible injury or death to personnel.
Ensure that all air lines and components removed or openings into the air system that
provides breathing air are covered with a plastic bag and secured with a rubber band or
taped shut. Small components should be stored in a plastic bag and sealed. Failure to
do so will cause air system to become contaminated and could result in injury or death to
the diver.
