Xstream Deco/Duration Cleaning for Oxygen Use

The process of cleaning for oxygen use and the information given herein shall be strictly adhered to. Only then can Poseidon
guarantee the regulator will be cleaned to a cleanliness level which is acceptable for its intended use. This process has been
verified to produce hydrocarbon residual levels less than 50mg/m2 and a particulate level less than Cleaning Test Level 100
(ASTM G 93 Spec.)
As an alternative, oxygen servicing procedures can be carried out in accordance with other herein listed organizations standard
procedures and requirements. However, the use of cleaning agents, the order of the operating sequences and the time to treat
parts during ultra sonic cleaning as specified in this manual must be adhered to. Wherever there is a conflict between the
procedures and set of requirements, unless the other procedure represents a greater requirement for cleanliness, this manual
takes precedence. Some methods, equipment, and detergents which are not mentioned in this manual can have a harmful or
unknown effect on materials, such as e.g. ozone cleaning systems, strong acids etc. and shall therefore be discarded.
The other standard procedures that can be used given the limitations above are:
EAN and Oxygen Servicing Procedures, Fourth Edition (ANDI)
IANTD Gas Blender & Service Technician Program, First Edition, August 1999
MIL-STD-1330D (SH) of the 20 September 1996
The safety of your customer and yourself depends on you carefully and strictly following these
instructions. Negligence in any step can cause serious injury or even death.
You must be certified by Poseidon as oxygen technician to undertake this procedure.
Keep hands and tools clean and free from grease, except for what is required and stated in this
manual.
Use protective clothing to prevent dust, fingerprints, hair, and particles to contaminate.
Use only dedicated and cleaned tools.
Ensure your oxygen handling is in conjunction with national laws.
Ensure no foreign contaminants, such as e.g. liquids, grease, particulate, dust, and mist can enter
into the cleanroom area.

The cleanroom area and work environment requirements

The cleanroom area and work environment should be setup according to minimum demands listed in Appendix D. A cleanroom
area and work environment audit should be performed once a year either by a service technician or by a from Poseidon
appointed auditor. The checklist in Appendix D should be used to make sure that all criterias are fulfilled. For detailed instructions
on how to perform and audit please refer to Appendix D.

Preparations and Pre-cleaning

1. These preparations and the pre-cleaning shall NOT be conducted in the clean room,
since it may then contaminate the clean room.
2. If any part is visibly contaminated, it shall be pre-cleaned, including the parts listed below
which shall not be ultra sonic cleaned.
3. Only undertake the pre-cleaning if you are sure you can move on to the cleaning stage
immediately after. If the parts dry between the two stages of operation, undesirable
deposits can be left on part surfaces.
4. Bag the parts below in a plastic bag for later assembly. These parts shall not be ultra
sonic cleaned.
5. Use IPA and a toothbrush to agitate away all visible contaminants. Rinse part(s) in
municipal running water until all visible soil, particulate and cleaning agent is
removed. When using IPA make sure you have sufficient ventilation. Please refer to
the safety instructions of the IPA.
6. Use air of any quality to blow dry.
