49 CFR Ch. I (10-1-18 Edition)

intermediate bulk containers (IBC) and
UN13H4 woven plastic, coated and with
liner flexible intermediate bulk containers (FIBCs) meeting the Packing
Group II performance level and lined
with a plastic liner of at least 6 mil
thickness.
d. All inner packagings placed inside bulk
outer packagings must be blocked and
braced to prevent movement during
transportation that could cause the container to open or fall over. Specification
IBCs and FIBCs are to be secured to a
pallet.
B132 Except for transportation by aircraft,
UN2813, Water reactive solid, n.o.s. (contains magnesium, magnesium nitrides) in
PG II or III may be packaged in sift-proof
bulk packagings that prevent liquid from
reaching the hazardous material with sufficient venting to preclude dangerous accumulation of flammable, corrosive or toxic
gaseous emissions such as methane, hydrogen and ammonia.
B133 Hydrochloric acid concentration not
exceeding 38%, in Packing Group II, is authorized to be packaged in UN31H1 or
UN31HH1 intermediate bulk containers
when loaded in accordance with the requirements of Section 173.35(h) of this subchapter.
B134 For Large Packagings offered for
transport by vessel, flexible or fibre inner
packagings shall be sift-proof and waterresistant or shall be fitted with a sift-proof
and water-resistant liner.
B135 For Large Packagings offered for
transport by vessel, flexible or fibre inner
packagings shall be hermetically sealed.

(4) IB Codes and IP Codes. These provisions apply only to transportation in
IBCs and Large Packagings. Table 1 authorizes IBCs for specific proper shipping names through the use of IB Codes
assigned in the Section 172.101 table of this
subchapter. Table 2 defines IP Codes on
the use of IBCs that are assigned to
specific commodities in the Section 172.101
Table of this subchapter. Table 3 authorizes Large Packagings for specific
proper shipping names through the use
of IB Codes assigned in the Section 172.101
table of this subchapter. Large Packagings are authorized for the Packing
Group III entries of specific proper
shipping names when either special
provision IB3 or IB8 is assigned to that
entry in the Section 172.101 Table. When no IB
code is assigned in the Section 172.101 Table
for a specific proper shipping name, or
in Section 173.185 or Section 173.225(e) Organic Peroxide Table for Type F organic peroxides, use of an IBC or Large Packaging
for the material may be authorized
when approved by the Associate Administrator. The letter  - Z -  shown in
the marking code for composite IBCs
must be replaced with a capital code
letter
designation
found
in
Section 178.702(a)(2) of this subchapter to
specify the material used for the other
packaging. Tables 1, 2, and 3 follow:
