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 specification for ``Specially Equipped Freight Car and 

Intermodal Equipment'' (IBR, see Sec. 171.7 of this subchapter) and the 

load is also within the limits of the design strength requirements for 

the doors.
