(a) General. When the Sec. 172.101 table of this subchapter specifies that a Division 4.1 material be packaged in accordance with this section, only packagings which conform to the provisions of this section may be used. Each packaging must conform to the general packaging requirements of subpart B of this part and the applicable requirements of part 178 of this subchapter. Non-bulk packagings must meet Packing Group II performance levels. To avoid unnecessary confinement, metallic non-bulk packagings meeting Packing Group I are not authorized. Self-reactive materials which require temperature control are subject to the provisions of Sec. 173.21(f). Packagings required to bear a Class 1 subsidiary label must conform to Secs. 173.60 through 173.62.
(b) Self-Reactive Materials Table. The Self-Reactive Materials Table specifies, by technical name, those self-reactive materials that are authorized for transportation and not subject to the approval provisions of Sec. 173.124(a)(2)(iii). A self-reactive material identified by technical name in the following table is authorized for transportation only if it conforms to all applicable provisions of the table. The column headings of the Self-Reactive Materials Table are as follows:
(1) Technical name. Column 1 specifies the technical name.
(2) ID number. Column 2 specifies the identification number which is used to identify the proper shipping name in the Sec. 172.101 table.
(3) Concentration of self-reactive material. Column 3 specifies the concentration (percent) limitations, if any, in mixtures or solutions for the self-reactive material. Limitations are given as minimums, maximums, or a range, as appropriate. A range includes the lower and upper limits (i.e., ``53-100'' means from, and including, 53 percent to, and including 100 percent).
(4) Packing method. Column 4 specifies the highest packing method which is authorized for the self-reactive material. A packing method corresponding to a smaller package size may be used, but a packing method corresponding to a larger package size may not be used. The Table of Packing Methods in Sec. 173.225(d) defines the packing methods. Bulk packagings for Type F self-reactive substances are authorized by Sec. 173.225(f) for IBCs and Sec. 173.225(h) for bulk packagings other than IBCs. Additional bulk packagings are authorized if approved by the Associate Administrator.
(5) Control temperature. Column 5 specifies the control temperature in C. Temperatures are specified only when temperature controls are required (see Sec. 173.21(f)).
(6) Emergency temperature. Column 6 specifies the emergency temperature in C. Temperatures are specified only when temperature controls are required (see Sec. 173.21(f)).
(7) Notes. Column 7 specifies other applicable provisions, as set forth in notes following the table.
