WARNING
Cleanliness is imperative in maintaining and handling diving air 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.
