GUIDANCE ON PACKAGING AND TRANSPORTATION After cleaning components including the assembly parts

25、 and tubing, they must be taken from the work area and kept clean. Once cleaned parts are assembled into a clean component, all openings should be plugged or capped. Boxing the component is considered suitable. An example of this could be a breathing Regulator or tubing. If the parts are not assembl

26、ed, but must be taken from the controlled work area for shipment, then special precautions must be taken for packaging to keep the components clean. Any equipment that is shipped containing compressed, chemical or liquid oxygen must be treated as hazardous material. SAE INTERNATIONAL AIR5742A Page 4

27、 of 7 3.1 General Packaging Issues Store all packaging components in a clean dry area. Protect them from contamination by grease, oil, dirt, flammable liquids, flammable dusts, or other flammable contaminants during storage and during packaging. The packaging area must be clean and completely free o

28、f grease, oil, other flammable contaminants, smoking or open flames. Only those persons trained in the inherent hazards of Aviation Oxygen in its various forms and trained in the handling of hazardous materials should attempt to package or offer for transport oxygen equipment. After completion of th

29、e final drying, all openings (where configuration permits) should be sealed using clean aluminum or plastic caps or plugs. Oxygen components, such as regulators, gauges, and valves shall have all open ports sealed with oxygen clean and non-shredding polyethylene plugs or caps. Green caps and plugs s

30、hould be used in order to avoid any confusion with the red caps and plugs used on oily equipment in the same assembly line and in case the equipment is to be capped again. Masking or other self-sealing tapes shall not be used on oxygen equipment. Paper, pressure sensitive materials, hot dip coatings

31、, rubber, or soft plastic closures that may introduce moisture, adhesives, or particles should not be used. High-density clean plastic closures such as Teflon or polyethylene are acceptable. Where a cap or plug cannot be used, the opening should be sealed in a manner that insures protection from con

32、tamination. The part or assembly should then be packaged, if required, in accordance with the part or assembly process control. In addition to regulatory packaging and transportation requirements, there may be specific customer requirements to be taken into account. NOTE: Preservatives, primarily oi

33、ls shall not be applied to the oxygen equipment part or assembly. NOTE: After the openings are closed, the components should be sealed in a polyethylene bag or equivalent dated and identified as being cleaned for oxygen service. If the cleaned components are to be shipped by air, the bags must be ev

34、acuated before sealing to prevent air expansion from breaking the bags at altitude. Clean plastic wrap or bags made preferably of polyethylene material should be used. Plastic material of not less than 0.004 inch thickness is recommended. Zip lock bags are not desirable. The recommended practice is

35、to use two separate bags, heat sealing the first bag, and then heat-sealing this bag in a second outer bag. Multi-folding the outer bag and stapling it is an acceptable alternative method of packaging oxygen clean parts. The packaging material should be of such cleanliness that the items packed ther

36、ein would not be contaminated by contact with the packaging. Items that will be reassembled after the final cleaning and drying need not be packaged if they remain in the clean “work area” and are assembled as soon as possible. SAE INTERNATIONAL AIR5742A Page 5 of 7 3.1.1 Packaging for Shipment Adeq

37、uate acceptable containers appropriate for the size and weight of the component should be used for shipping. Cushioning material and durable containers are desired for packaging for shipment. Usually, it is best to place plastic wrapped parts and assemblies in containers like cardboard boxes with ap

38、propriate cushioning material in “work areas” outside the clean room(s). These materials tend to leave excess contaminants on the work surface and in the surrounding air. Best commercial practices may be found in the process control document and should be followed. Procedures should ensure that each

39、 item is packed for transit and storage in strict accordance with ATA 300 specification for delivery to the aircraft operator or with the purchasers instructions for delivery to the purchaser (OEM). Alternative packaging may be agreed to with the purchaser. Handling requirements specified by the equ

40、ipment manufacturer should be taken into account and are usually included in the Manufacturers component maintenance manual (CMM). 3.1.2 Marking Nomenclature tags should be inserted in each bag or securely attached to the package and shipping container, showing title, part number, or other data as r

41、equired, so that the contents can be readily identified without breaking the label. In addition, labels should be attached to the unit package and shipping container and should include the following or similar information: Figure 1 - Label example for content identification 3.2 Chemical Oxygen Equip

42、ment The term chemical oxygen equipment, as used in this document, includes chemical oxygen generators and associated equipment, e.g., passenger service units (PSU), portable breathing equipment (PBE), etc. According to Hazardous Material Regulations, reference 49 CFR Part 173, Shippers-General Requ

43、irements for Shipment and Packaging, in 173.168 “Chemical Oxygen Generators”, requirements can be summarized as following: Chemical Oxygen Generator must be approved in accordance with procedure specified in 173.56. Chemical Oxygen Generator must be capable of withstanding a 1.8 m drop on concrete.

44、Inadvertent activation must be avoided by redundant means, e.g., mechanically actuated devices need two pins, each independently preventing actuation. Chemical Oxygen Generator including those installed in equipment (e.g., PBE, PSU) must be placed in rigid packaging to conform with 173.168 (d) and (

45、e). Packaging must meet the flame penetration resistance as required for cargo compartment sidewalls and ceiling panels according to Part III of Appendix F to 14 CFR Part 25, 1700 F (926 C) for 5 minutes. Transportation is forbidden on board a passenger-carrying aircraft. SAE INTERNATIONAL AIR5742A

46、Page 6 of 7 On cargo-only aircraft chemical oxygen generator transportation is forbidden if: - The manufacturers expiration date is exceeded. - The generator content has expired. 3.3 Gaseous Oxygen Equipment “Gaseous Oxygen Equipment” differentiation should be made as follows: For equipment not cont

47、aining any fluid at the time of shipment, e.g., pneumatic/electric valves, non-return valves, regulators, etc., the requirements specified in manufacturers component maintenance manual (CMM) should be adhered to for packaging and transportation. Cylinders containing compressed oxygen are authorized

48、for transportation by aircraft according to requirements of 173.302a which are in summary: - The packaging must meet the same flame penetration resistance as that for chemical oxygen equipment stated in 3.2. - Packaging must prevent an increase of the external cylinder temperature above 200 F (93 C)

49、 when exposed to 400 F (205 C) for 3 hours. - The pressure relief device (PRD) setting limit has to be set between 90 and 100% of the test pressure for all oxygen cylinders transported aboard aircraft. - Transportation is limited to Type 3A, 3AA, 3AI, and 3HT cylinders. - Transportation of composite cylinders has to be authorized by SPECIAL PERMIT (DOT Exemption). - The number of oxygen cylinders allowed f
