Sec.  174.112  Loading Division 1.3 materials and Division 1.2 (explosive) 
materials (Also see Sec.  174.101).

    (a) Division 1.3 materials and Division 1.2 (explosive) materials 
may not be loaded, transported or stored in a rail car equipped with any 
type of lighted heater or open-flame device, or in a rail car equipped 
with any apparatus or mechanism utilizing an internal combustion engine 
in its operation.
    (b) Except as provided in Sec.  174.101(b), (n), or (o) Division 1.3 
materials and Division 1.2 (explosive) materials must be transported in 
a closed car or container car which is in good condition, and into which 
sparks cannot enter. The car does not require the car certificates 
prescribed in Sec.  174.104(c) through (f). If the doors are not tight, 
they must be stripped to prevent the entrance of sparks. Wood floored 
cars must be equipped with spark shields (see Sec.  174.104). Packages 
of Division 1.3 materials and Division 1.2 (explosive) materials must be 
blocked and braced to prevent their movement and possible damage due to 
movement of other freight during transportation. For recommended methods 
of blocking and bracing see Bureau of Explosives Pamphlet No. 6.
    (c) Division 1.3 materials and Division 1.2 (explosive) materials 
may not be transported in a truck body, trailer, or container on a 
flatcar unless:
    (1) The truck body, trailer, or container is closed and tight;
    (2) All automatic heating or refrigerating machinery with which the 
truck body, trailer, or container is equipped is inoperative; and
    (3) Packages of Division 1.3 materials and Division 1.2 (explosive) 
materials are blocked and braced within the truck body, trailer, or 
container to prevent their movement and possible damage due to movement 
of other freight during transportation (ends, sidewalls, or doors of the 
truck body, trailer, or container may not be relied on to prevent the 
shifting of heavy loads). For recommended methods of blocking and 
bracing see Bureau of Explosives Pamphlet No. 6C. See Sec.  174.101(o).
