Section 4 IATA Identification

Editor's Notes

• #4: Go to Page 3-1-1. TAB this Page. We have Classified to see if something is a Dangerous Good or not. If it is, then we have to identify it more specifically. We’ll do this by giving it a Proper Shipping Name. This term means just what it sounds like—there is a proper (legal) name that must be used when shipping this material. Paragraph 1.2 contains rules for Proper Shipping Names —we’ll come back to this. The Blue Pages of the book contain the Dangerous Goods List which contains an alphabetical listing of all the proper shipping names.
• #6: UN numbers are useful in identifying dangerous goods because, no matter what language is being spoken, the whole world uses the same number system. Also, those who can’t read or write very well usually will recognize numbers. Go to Attachment 1 in the back of the book. Show that this list is in numeric order. Exercise: Cite some numbers and have the class give you the PSN. Examples: 0094 = Flash Powder, 1714 = Zinc Phosphide, 1203 = Gasoline/Motor Spirit/Petrol (each is a good PSN).
• #7: Go the first Blue Page in the DG List. Show that there are 12 Columns. Turn back a page and show that there are explanations/rules for each column. These are very helpful--You don’t need to memorize the rules for the DG List, this is a handy reference for each column.
• #16: The UN# should be considered a six-character code since “UN” must precede the 4-digit number when entered on shipping papers and when marked on packages. Go to UN list in Attachment 1. Have students write “ID” in front of any numbers in the 8000 series. Have them look up PSN’s by their UN# (1203, 0030, 3268, etc.)
• #17: DGL is alphabetical. Chemical prefixes are not used in alphabetization (N, N-Dimethyl…. Is with the “D”s not the “N”s. Exercise: Write “1,1-Difluoroethane” on the board and have students look it up. Only names in bold are PSN’s. Most names not in bold will reference a good PSN that is in bold. Have students look up “Dynamite” and give you the correct PSN (Explosives, Blasting, Type A) . Those non-bold names that do not reference a good PSN are substances that are forbidden from all modes of transportation, therefore the UN has not assigned a PSN to them. Note that dynamite (Explosives, Blasting, Type A) is forbidden from air transportation (see DGL columns 9 thru 12) but it has a proper shipping name because it is commonly shipped by other modes of transport. On the slide point out the symbols used on the entries for “Aerosols”, “Batteries…” and “Flam liquid n.o.s.”. Direct student to paragraph 2.1.2 right before the Blue Pages start and review the symbols. Look at the “†” symbol. Then look at the Glossary it refers to in Attachment A2. Discuss the meaning of “NOS”. Go to A1, Chap. 2, and look at the list of generic names. When the Shipper writes PSN’s on packages or shipping papers there is no requirement to make them “bold” or in all capitalized letters or any other special font or style.
• #18: The non-bold text that sometimes follows a bold PSN (see “Aerosols, flammable” on slide or in book ) may be used when marking the proper shipping name on packages and shipping papers but it is not mandatory.
• #19: The non-bold text that sometimes follows a bold PSN (see “Aerosols, flammable” on slide or in book ) may be used when marking the proper shipping name on packages and shipping papers but it is not mandatory.
• #20: The non-bold text that sometimes follows a bold PSN (see “Aerosols, flammable” on slide or in book ) may be used when marking the proper shipping name on packages and shipping papers but it is not mandatory.
• #21: This is a good example of IATA (airline) requirements that can’t be enforced. IATA cannot make up its own PSN’s. But because ICAO allows the non-bold words to be used with the PSN it is not a violation to use them the way IATA requires.
• #22: In this slide, all three examples are flammable liquids. A flammable solution containing alcohol might be assigned to any of these depending on what the shipper knows about the solution. Look at the list of generic and NOS names in Attachment 1, Chapter 2. Remember, the hazard class and any sub-risks are already determined before you go to select a generic/NOS name. For example, “Aldehydes, NOS”, a Class 3 name, cannot be assigned to all “aldehydes” since some are not flammable but toxic or corrosive.
• #23: If the material meets more than one hazard class/div., this is the primary hazard class/div. There is only one primary hazard class/div., all other classes/divs met will be subsidiary risks.
• #24: Primary hazard class label is shown first. These are just hazard labels. Other handling labels (e.g., Cargo Aircraft Only) may apply to a shipment also. We’ll discuss labeling in depth later.
• #25: TAB Table 3-2 EXERCISE Look up some examples: Batteries, wet, filled with Alkali – A51 Batteries, wet, non-spillable - A67 Methanol - A104 Oxygen generators, chemical - A111 Sulphur - A105 Notice how special provisions may provide relief from the TI or may make it more difficult to ship –including forbidding certain shipments.
• #26: Look up Fuel, Aviation, Turbine Engine in the DGL. Notice that all three PG’s are listed since this PSN covers a wide variety of products. You’ll need to know the flash point and boiling point to select the proper PG. Look up Gasoline and see there is only one PG to choose from. Look up Aerosol. There’s no PG since Class 2 doesn’t have packing groups. Using this slide, show how the lower packing groups in Column 8 have lower net quantities per package in Column 10. Briefly mention that we will use these Packing Groups again when we discuss package testing – how strong packagings have to be.

• #28: Column 9 & 10 are for PASSENGER AIRCRAFT. --If something’s prepared for passenger aircraft it can also go on cargo aircraft. The packing instructions numbers that start with “Y” are for limited quantities. We’ll ignore these now and cover Limited Quantities later. L = Liters, Kg = Kilograms, G = Gross weight (These symbols can be found in 3; 2.1) Net quantity per package refers to the actual net quantity limit of dangerous goods in each package (box or drum)—Not the limit for each inner receptacle, not for the whole consignment, and not for the aircraft. (Draw picture if necessary. Can also look at definition for “package”.) Look up “Batteries, wet, filled with alkali”. In this case, there is a “G” in Column 10 so the quantity limit is based on the gross weight of the whole package not the weight of the battery or the amount of acid in the battery. When these columns say “FORBIDDEN” then it can’t go on passenger aircraft. Check Columns 11 & 12 to see if it can go on cargo-only aircraft.
• #29: Column 9 & 10 are for PASSENGER AIRCRAFT. --If something’s prepared for passenger aircraft it can also go on cargo aircraft. The packing instructions numbers that start with “Y” are for limited quantities. We’ll ignore these now and cover Limited Quantities later. L = Liters, Kg = Kilograms, G = Gross weight (These symbols can be found in 3; 2.1) Net quantity per package refers to the actual net quantity limit of dangerous goods in each package (box or drum)—Not the limit for each inner receptacle, not for the whole consignment, and not for the aircraft.

When these columns say “FORBIDDEN” then it can’t go on passenger aircraft. Check Columns 11 & 12 to see if it can go on cargo-only aircraft.
• #30: Columns 11 & 12 are under the “Cargo Aircraft” heading. Notice that the Net Quantities allowed are higher for Cargo aircraft packing instructions. DG prepared in accordance with Passenger Aircraft packing instructions can go also go on Cargo Aircraft (if it’s safe enough to fly on passenger aircraft then it’s safe enough to go on cargo aircraft) . DG prepared in accordance with a cargo aircraft packing instruction can not go on passenger aircraft. (These packages will get a Cargo-Aircraft-Only label and the shipping paper will indicate “Cargo Aircraft Only”).
• #31: Look up Acetone in the blue pages. LTD QTY will be covered later. Compare PI 305 with PI 307. PI 305 is good for Passenger AND Cargo aircraft. PI 307 can only be used for Cargo Aircraft. ASK: Can a person ship 10 liters of Acetone on a passenger aircraft? Answer: Yes, but it will have to divided into packages of five liters or less. What about 100 liters? Same answer. ASK: Can we use a drum or jerrican (single packaging) for our 5-liter package of acetone on passenger aircraft? How about a 5-liter glass bottle inside a box? Answer: At this point we don’t know. We have to go to PI 305 in the yellow pages to see what types of packagings are allowed. We’ll do that later.
