§176.140. Segregation from other classes of hazardous materials.

49 C.F.R. § 176.140

(a)
Class 1 (explosive) materials must be segregated from other packaged hazardous materials in accordance with § 176.83.
(b)
Class 1 (explosive) materials must be segregated from bulk solid dangerous cargoes in accordance with the IMDG Code (IBR, see § 171.7 of this subchapter). Notwithstanding § 176.83(b), ammonium nitrate and sodium nitrate may be stowed together with blasting explosives, except those containing chlorates, provided the mixed stowage is treated as blasting explosives (see § 176.410(e)).

§176.144. Segregation of Class 1 (explosive) materials.

49 C.F.R. § 176.144

(a)
Except as provided in § 176.145 of this subchapter, stowage of Class 1 (explosive) materials within the same compartment, magazine, or cargo transport unit is subject to provisions contained in table 176.144(a).
(b)
Where Class 1 (explosive) materials of different compatibility groups are allowed to be stowed in the same compartment, magazine, or cargo transport unit, the stowage arrangements must conform to the most stringent requirements for the entire load.
(c)
Where a mixed load of Class 1 (explosive) materials of different hazard divisions and/or stowage arrangements is carried within a compartment, magazine, or cargo transport unit, the entire load must be treated as belonging to the hazard division having the greatest hazard. (For example, if a load of Division 1.1 (explosive) materials is mixed with Division 1.3 (explosive) materials, the load is treated as a Division 1.1 (explosive) material as defined in § 173.50(b) of this subchapter and the stowage must conform to the most stringent requirements for the entire load).
(d)
If some of the Class 1 (explosive) materials in a stowage mixture require non-metallic lining of the closed cargo transport unit, Class 1 (explosive) materials requiring ordinary stowage may be stowed in the same closed cargo transport. When a closed cargo transport unit is used for such substances that require non-metallic lining of the closed cargo transport unit, the other Class 1 (explosive) materials stowed therein must have no exposed parts of any ferrous metal or aluminum alloy, unless separated by a partition.
(e)
Segregation on deck— When Class 1 (explosive) materials in different compatibility groups are carried on deck, they must be stored not less than 6 m (20 feet) apart unless they are allowed under Table 176.144(a) to be stowed in the same compartment, magazine, or cargo transport unit.
(f)
On a barge used to transfer class 1 (explosive) materials from a waterfront facility to a vessel at an explosives anchorage (or from the vessel to the water front facility), if compliance with paragraph (e) of this section is not practicable, a sandbag barrier at least 0.6 m (2 feet) in thickness may be substituted for the 6 m (20 feet) separation.

§176.145. Segregation in single hold vessels.

49 C.F.R. § 176.145

(a)
On board a vessel having a single cargo hold, Class 1 (explosive) materials in hazard division/compatibility group 1.1B and 1.2B may be stowed in the same compartment with substances of compatibility group D, provided:
(1)
The net explosive weight of the compatibility group B explosive does not exceed 50 kg (110 pounds); and
(2)
The compatibility group B explosive materials are stowed in a steel portable magazine that is stowed at least 6 m (20 feet) from the compatibility group D substances.
(b)
Division/compatibility group 1.4B (explosive) materials may be stowed in the same compartment with substances of compatibility group D provided the Class 1 (explosive) materials of different compatibility groups are separated by either a distance of at least 6 m (20 feet) or by a steel partition.

§176.146. Segregation from non-hazardous materials.

49 C.F.R. § 176.146

(a)
Except as required by paragraph (b) of this section, Class 1 (explosive) materials need not be segregated from other cargo of a non-dangerous nature.
(b)
Readily combustible materials may not be stowed in the same compartment or hold as Class 1 (explosive) materials other than those in compatibility group S.
(c)
[Reserved]
(d)
In order to avoid contamination—
(1)
An explosive substance or article which has a secondary POISON hazard label must be stowed “separated from” all foodstuffs, except when such materials are stowed in separate closed cargo transport units, the requirements for “away from” segregation apply.
(2)
An explosive substance or article which has a secondary CORROSIVE hazard label must be stowed “away from” foodstuffs.
