TITLE 49--TRANSPORTATION
CHAPTER I--RESEARCH AND SPECIAL PROGRAMS ADMINISTRATION, DEPARTMENT OF
TRANSPORTATION
PART 173--SHIPPERS--GENERAL REQUIREMENTS FOR SHIPMENTS AND PACKAGINGS
--Table of Contents
Subpart E--Non-bulk Packaging for Hazardous Materials Other Than Class 1
and Class 7
Sec. 173.225 Packaging requirements and other
provisions for organic peroxides.
(a) General. When the Sec. 172.101 table specifies that an organic
peroxide be packaged under this section, the organic peroxide must be
packaged and offered for transportation in accordance with the
provisions of this section. Each packaging must conform to the general
requirements of subpart B of part 173 and to 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. No used
material, other than production residues or regrind from the same
production process, may be used in plastic packagings. Organic peroxides
which require temperature control are subject to the provisions of
Sec. 173.21(f).
(b) Organic peroxides table. The following Organic Peroxides Table
specifies, by technical name, those organic peroxides that are
authorized for transportation and not subject to the approval provisions
of Sec. 173.128 of this part. An organic peroxide identified by
technical name in the following table is authorized for transportation
only if it conforms to all applicable provisions of the table. For an
organic peroxide not identified in the table by technical name or a
formulation of identified organic peroxides, the provisions of paragraph
(c) of Sec. 173.128 apply. The column headings of the Organic Peroxides
table are as follows:
(1) Technical name. The first column specifies the technical name.
[[Page 481]]
(2) ID number. The second column specifies the identification (ID)
number which is used to identify the proper shipping name in the
Sec. 172.101 table. The word ``EXEMPT'' appearing in the column denotes
that the material is not regulated as an organic peroxide.
(3) Concentration of organic peroxide. The third column specifies
concentration (mass percent) limitations, if any, in mixtures or
solutions for the organic peroxide. 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) Concentration of diluents. The fourth column specifies the type
and concentration (mass percent) of diluent or inert solid, when
required. Other types and concentrations of diluents may be authorized
if approved by the Associate Administrator for Hazardous Materials
Safety.
(i) The required mass percent of ``Diluent type A'' is specified in
column 4a. A diluent type A is an organic liquid that does not
detrimentally affect the thermal stability or increase the hazard of the
organic peroxide and with a boiling point not less than 150 deg.C at
atmospheric pressure. Type A diluents may be used for desensitizing all
organic peroxides.
(ii) The required mass percent of ``Diluent type B'' is specified in
column 4b. A diluent type B is an organic liquid which is compatible
with the organic peroxide and which has a boiling point, at atmospheric
pressure, of less than 150 deg.C (302 deg.F) but at least 60 deg.C
(140 deg.F), and a flash point greater than 5 deg.C (41 deg.F). Type
B diluents may be used for desensitizing all organic peroxides provided
that the boiling point is at least 60 deg.C (140 deg.F) above the SADT
of the peroxide in a 50 kg (110 lbs) package. A type A diluent may be
used to replace a type B diluent in equal concentration.
(iii) The required mass percent of ``Inert solid'' is specified in
column 4c. An inert solid is a solid that does not detrimentally affect
the thermal stability or increase the hazard of the organic peroxide.
(5) Concentration of water. Column 5 specifies, in mass percent, the
minimum amount of water, if any, which must be in formulation.
(6) Packing method. Column 6 specifies the highest packing method
(largest packaging capacity) authorized for the organic peroxide. Lower
numbered packing methods (smaller packaging capacities) are also
authorized. For example, if OP3 is specified, then OP2 and OP1 are also
authorized. When an IBC or bulk packaging is authorized and meets the
requirements of paragraph (e) of this section, lower control
temperatures than those specified for non-bulk packagings are required.
The Table of Packing Methods in paragraph (d) of this section defines
the non-bulk packing methods.
(7) Temperatures. Column 7a specifies the control temperature.
Column 7b specifies the emergency temperature. Temperatures are
specified only when temperature controls are required. (See
Sec. 173.21(f)).
(8) Notes. Column 8 specifies other applicable provisions, as set
forth in notes following the table.

(b) of this section, for which complete test data are not available, and
which are to be transported for further testing or evaluation, may be
assigned an appropriate shipping description for organic peroxide Type
C, packaged and offered for transportation, under the following
conditions:
(i) Data available to the person offering the material for
transportation must indicate that the sample would pose a level of
hazard no greater than that of an organic peroxide Type B and that the
control temperature, if any, is sufficiently low to prevent any
dangerous decomposition and sufficiently high to prevent any dangerous
phase separation;
(ii) The sample must be packaged in accordance with packing method
OP2, for a liquid or solid, respectively;
(iii) Packages of the organic peroxide may be offered for
transportation and transported in a quantity not to exceed 10 kg (22
pounds) per transport vehicle; and
(iv) One of the following shipping descriptions must be assigned:
(A) Organic peroxide Type C, liquid, 5.2, UN 3103;
(B) Organic peroxide Type C, solid, 5.2, UN 3104;
(C) Organic peroxide Type C, liquid, temperature controlled, 5.2, UN
3113; or
(D) Organic peroxide Type C, solid, temperature controlled, 5.2, UN
3114.
(3) Mixtures. Mixtures of organic peroxides individually identified
in the Organic Peroxides Table in paragraph (b) of this section may be
classified as the same type of organic peroxide as that of the most
dangerous component and be transported under the conditions for
transportation given for this type. If the stable components form a
thermally less stable mixture, the SADT of the mixture must be
determined and the new control and emergency temperature derived under
the provisions of Sec. 173.21(f).
(d) Packing Method Table. Packagings for organic peroxides and self-
reactive substances are listed in the Maximum Quantity per Packing
Method Table. The packing methods are designated OP1 to OP8. The
quantities specified for each packing method represent the maximum that
is authorized.

maximum net mass of the complete package.
\2\ 60 kg for jerricans and 100 kg for boxes.
\3\ 60 L for jerricans.
(e) Bulk packagings for organic peroxides. When bulk packagings are
authorized under the provisions of the Organic Peroxides Table in
paragraph (b) of this section, only the following packagings are
authorized:
(1) Rail cars. Class DOT 103, 104, 105, 109, 111, 112, 114, 115, or
120 fusion-weld tank car tank are authorized. DOT 103W, 111A60F1 and
111A60W1 tank car tanks must have bottom outlets effectively sealed from
inside. Gauging devices are required on DOT 103W tank car tanks. Riveted
tank car tanks are not authorized.
(2) Cargo tanks. Specification MC 307, MC 310, MC 311, MC 312, DOT
407, and DOT 412 cargo tank motor vehicles with a tank design pressure
of at least 172 kPa (25 psig) are authorized.
(3) Portable tanks.
(i) Specification IM 101 intermodal portable tanks are authorized as
follows:
(A) Each tank must have a minimum design pressure of 267 kPa (39
psig), a minimum shell thickness of 6.35 mm (0.250 inch) mild steel.
(B) Each tank must be equipped with at least two self-reclosing
pressure relief devices of at least 7.6 cm (3.0 inches) diameter. The
pressure relief devices must be set at a pressure that is determined by
the following formula:
Pressure relief valve setting = 1.2 x [Vapor pressure of lading at 46
deg.C (115 deg.F)+Static head of lading+Pressure of gas
padding, if any]
(ii) Specification 57 metal portable tanks are authorized only for
tert-butyl cumyl peroxide, di-(2-tert-butylperoxyisopropyl-benzene(s),
dicumyl peroxide and mixtures of two or more of these peroxides.
(4) For tertiary butyl hydroperoxide (TBHP), each tank car, cargo
tank or portable tank must contain 7.6 cm (3.0 inches) low density
polyethylene (PE) saddles having a melt index of at least 0.2 grams per
10 minutes (ASTM D1238, condition E) as part of the lading, with a ratio
of PE to TBHP over a range of 0.008 to 0.012 by mass. Alternatively,
plastic or metal containers equipped with fusible plugs having a melting
point between 69 deg.C (156 deg.F) and 71 deg.C (160 deg.F) and
filled with a sufficient quantity of water to dilute the TBHP to 65
percent or less by mass may be used. The PE saddles must be visually
inspected after each trip and, at a minimum, once every 12 months, and
replaced when discoloration, fracture, severe deformation, or other
indication of change is noted.
(5) Intermediate bulk containers. Intermediate bulk containers that
are tested at the Packing Group II performance level in accordance with
subpart O of part 178 of this subchapter are authorized as follows:
