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 Chapter 4,
Section VII of this manual. 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.
