DEFINITIONS Associate Administrator - means the Associate
18、Administrator for Hazardous Materials Safety, Pipeline and Hazardous Materials Safety Administration. Chemical Oxygen Generator - means a device containing a compound with chemically bonded oxygen which, when properly activated, will provide a supply of gaseous oxygen at a purity, rate, and quantity
19、 suitable for breathing. Cylinder - means a pressure vessel designed for pressures higher than 40 psia and having a circular cross section. Dangerous Goods - means articles or substances which are capable of posing a risk to health, safety, property or the environment and which are shown in the list
20、 of dangerous goods in the Technical Instructions or which are classified according to those instructions. Hazardous Material - means a substance or material that may pose an unreasonable risk to health, safety, or property when transported in commerce. Packaging - means a receptacle and any other c
21、omponents or materials necessary for the receptacle to perform its containment function. Special Permit - means a document issued by the Associate Administrator permitting a person to perform a function that is not otherwise permitted. UN Number - is the four- digit number assigned by the United Nat
22、ions Committee of Experts on the Transport of Dangerous Goods to identify a substance or a particular group of substances. 4. GUIDANCE ON PACKAGING AND TRANSPORTATION After cleaning components including the assembly parts and tubing, they must be taken from the work area and kept clean. Once cleaned
23、 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 assembled, but must be taken from the controlled work area for shipment, then special
24、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.

25、ge 4 of 74.1 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
26、 of 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
27、the 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
28、 should 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 coatin
29、gs, 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 c
30、ontamination.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
31、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
32、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 in thickness is recommended. Zip lock bags are not desirable.The recommended practice is to
33、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 items would not be conta
34、minated again. 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.

35、f 74.1.1 Packaging for Shipment Adequate 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 con
36、tainers like cardboard boxes with appropriate 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
37、. Procedures should ensure that each 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. Handli
38、ng requirements specified by the equipment manufacturer should be taken into account and are usually included in the Manufacturers component maintenance manual (CMM) 4.1.2 Marking Nomenclature tags should be inserted in each bag or securely attached to the package and shipping container, showing tit
39、le, part number or other data as required, 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 IDENTI
40、FICATION 4.2 Chemical Oxygen Equipment 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, ref. 49 CFR Part
41、173-Shippers-General Requirements for Shipment And Packaging, in “ 173.168 Chemical Oxygen Generators”, requirements can be summarized as following: x Chemical Oxygen Generator must be approved in accordance with procedure specified in 173.56 x Chemical Oxygen Generator must be capable of withstandi
42、ng a 1,8m drop on concrete. x Inadvertent activation must be avoided by redundant means, e.g. mechanically actuated devices need two pins, each independently preventing actuation. x Chemical Oxygen Generator including those installed in equipment (e.g. PBE, PSU) must be placed in rigid packaging to
43、conform with 173.168 (d) (e). x Packaging must meet the flame penetration resistance as required for cargo compartment sidewalls and ceiling panels according Part III of Appendix F to 14 CFR Part 25, 1700 F / 926 C for 5 minutes. x Transportation is forbidden on board a passenger-carrying aircraft.
