PART 174_CARRIAGE BY RAIL--Table of Contents
 
           Subpart C_General Handling and Loading Requirements
 
Sec.  174.55  General requirements.


    (a) Each package containing a hazardous material being transported 
by rail in a freight container or transport vehicle must be loaded so 
that it cannot fall or slide and must be safeguarded in such a manner 
that other freight cannot fall onto or slide into it under conditions 
normally incident to transportation. When this protection cannot be 
provided by using other freight, it must be provided by blocking and 
bracing. For examples of blocking and bracing in freight containers and 
transport vehicles, see Bureau of Explosives Pamphlet Nos. 6 and 6C.
    (b) Each package containing a hazardous material bearing package 
orientation markings prescribed in Sec.  172.312 of this subchapter must 
be loaded within a transport vehicle or freight container to remain in 
the correct position indicated by those markings during transportation.
    (c) The doors of a freight container or transport vehicle may not be 
used to secure a load that includes a package containing a hazardous 
material unless the doors meet the design strength requirements of 
Specification M-930 (for freight containers) and M-931 (for trailers) in 
the AAR's Manual of Standards and Recommended Practices and the load is 
also within the limits of the design strength requirements for the 
doors.
