General. This section covers the cleaning procedures for diving life support air systems. The importance ofmaintaining a diver's air breathing system in a clean and operable condition cannot be over emphasized. This procedureprovides basic steps and methods for removing and installing components and piping, and provides the simplifiedmethods for cleaning small components, pipes and hoses for air systems, and methods for cleaning component softgoods.4-37. Determining System Cleanliness . A periodic inspection of the air system will verify system cleanliness. If asystem is suspected of contamination, a hydrocarbon analysis, a particulate sample may be taken or a gas sample maybe drawn to determine the level of system cleanliness. These samples can be coordinated through the U.S. Army TroopCommand, ATTN: AMSTR-M, 4300 Goodfellow Blvd., St. Louis, Missouri 63120-1798.4-38. Clean Area. All cleaning for life support air systems to be performed on components and piping shall be cleanedin a "clean area." This area shall be isolated from oil, grease, paper, lint particles and other airborne contaminates. Itshall be as free as possible of dust and debris. Work benches shall be covered with easily cleaned surfaces such asstainless steel, synthetic rubber, vinyl linoleum or formica. Floor shall be non-dusting. Walls and ceiling shall becovered with washable vinyl, latex paint or polyurethane-based paint.4-39. Removing and Installing System Components or Piping . The following steps are guidelines for the removaland installation of piping or components from or into a clean system. In general, common sense and clean work habitsmust prevail at all times to maintain system cleanliness. Prior to the removal of any pipe or component, appropriatemaintenance forms are to be completed and approved.a.Removal.Extreme care shall be used in the removal of any component or pipe from a clean system to avoidintroducing any contamination. To eliminate any chance of contamination, the following steps shall be adhered to:(1) Secure the system by closing valves and controls both upstreamand downstream of the component or pipeto be removed. The components shall be tagged to insure that gas is not brought on line.4-78
