Attachment 4
ITEMS LISTING
A4.1. General Requirements. This attachment contains :
-
An alphabetical listing of the hazardous materials subject to the requirements of this manual. See
paragraph 1.10.3 for material determined to be nonhazardous.
-
Classification criteria for hazard classes. See attachment 1 for definitions.
-
Identification of items prohibited for military air transportation.
-
Listing of Hazardous Substances and applicable Reportable Quantities.
A4.2. Using Table A4.1. Table A4.1 identifies "hazardous materials” for the purpose of military air transportation.
To use table A4.1 locate the proper shipping name (PSN) of the hazardous material and follow the information
identified on the same line with the PSN. Use Table A4.1 to identify the follwing:
-
Eligibility of material for shipment
-
Proper shipping name (PSN)
-
Hazard class and division
-
Identification number
-
Packing group (PG)
-
Subsidiary Risk
-
Special provisions applicable to the material, including passenger eligibility
-
Basic packaging paragraph
A4.2.1. Column 1: Symbols. Column 1 contains symbols that pertain to the PSN.
-
The letter "D" means that the PSN applies only to domestic shipments. These items are also identified by
"NA" numbers in column 4. For international shipments, select an alternate PSN that is not preceded by a
"D".
-
The "*" (asterisk) identifies that a technical name is required in association with the PSN.
- The “+” (plus) fixes the proper shipping name, hazard class and packing group for that entry without regard
to whether the material meets the definition of that class or packing group or meets any other hazard class definition.
A4.2.2. Column 2: Proper Shipping Names (PSN). PSNs are listed alphabetically in all bold capital letters in
table A4.1. Use either singular or plural wording. New and revised PSNs in 49 CFR, part 172, ICAO Technical
Instructions, or IATA Dangerous Goods Regulation are authorized PSNs under this manual, provided the packaging
requirements do not change. Words which appear in lower case italicized letters are descriptive words which may
be used, but are not required as part of the PSN.
-
Technical or Chemical Group Names. Provide a technical or chemical group name in association with
the PSN when required by an “*” in column 1.
-
Organic Peroxides. Use technical names listed below the appropriate generic PSN (in lower case
letters) in table A4.1. See A4.3.6 for PSN assignment based on technical name.
-
Mixtures and Solutions. If the hazardous material is a mixture or solution of two or more hazardous
materials, enter the technical names of at least two components most contributing to the hazards of the
mixture or solution in parentheses after the PSN.
-
The Word "OR" in Table A4.1. The word "or" in a sequence of PSNs means that PSNs in the sequence
are synonymous. Therefore, use of any one of the PSNs in the series is appropriate. Select only one PSN
in the series when classifying the shipment.
-
The Word "SEE" in Table A4.1. When one item references another item (by use of the word "see") and
both names are in capital letters, use either name as the PSN. Forbidden designations and passenger
restrictions applicable to the referenced entry also apply to the "see" entry.
-
The Words “SOLUTION” or “MIXTURE”. A mixture or solution containing a hazardous material
listed by name in table A4.1 together with one or more materials not subject to this manual must be
identified by the PSN of the hazardous material. The qualifying word “solution” or “mixture” should be
added to the PSN.
-
Concentration Ranges. When a shipping name includes a concentration range as part of the shipping
description, the actual concentration shipped (if it is in the range stated) may be used in place of the
concentration range. For example, ship a hydrogen peroxide solution containing 30 percent peroxide as
