Sec. 172.302  General marking requirements for bulk packagings.



    (a) Identification numbers. Except as otherwise provided in this 

subpart, no person may offer for transportation or transport a hazardous 

material in a bulk packaging unless the packaging is marked as required 

by Sec. 172.332 with the identification number specified for the 

material in the Sec. 172.101 table--

    (1) On each side and each end, if the packaging has a capacity of 

3,785 L (1,000 gallons) or more;

    (2) On two opposing sides, if the packaging has a capacity of less 

than 3,785 L (1,000 gallons); or

    (3) For cylinders permanently installed on a tube trailer motor 

vehicle, on each side and each end of the motor vehicle.

    (b) Size of markings. Except as otherwise provided, markings 

required by this subpart on bulk packagings must--

    (1) Have a width of at least 6.0 mm (0.24 inch) and a height of at 

least 100 mm (3.9 inches) for rail cars;

    (2) Have a width of at least 4.0 mm (0.16 inch) and a height of at 

least 25 mm (one inch) for portable tanks with capacities of less than 

3,785 L (1,000 gallons) and IBCs; and

    (3) Have a width of at least 6.0 mm (0.24 inch) and a height of at 

least 50 mm (2.0 inches) for cargo tanks and other bulk packagings.

    (c) Exemption packagings. The outside of each bulk package used 

under the terms of an exemption shall be plainly and durably marked 

``DOT-E'' followed by the exemption number assigned.

    (d) Each bulk packaging marked with a proper shipping name, common 

name or identification number as required by this subpart must remain 

marked when it is emptied unless it is--

    (1) Sufficiently cleaned of residue and purged of vapors to remove 

any potential hazard; or

    (2) Refilled, with a material requiring different markings or no 

markings, to such an extent that any residue remaining in the packaging 

is no longer hazardous.

    (e) Additional requirements for marking portable tanks, cargo tanks, 

tank cars, multi-unit tank car tanks, and other bulk packagings are 

prescribed in Sec. Sec. 172.326, 172.328, 172.330, and 172.331, 

respectively, of this subpart.

    (f) A bulk packaging marked prior to October 1, 1991, in conformance 

to the regulations of this subchapter in effect on September 30, 1991, 

need not be remarked if the key words of the proper shipping name are 

identical to those currently specified in the Sec. 172.101 table. For 

example, a tank car marked ``ANHYDROUS AMMONIA'' need not be remarked 

``ANHYDROUS AMMONIA, LIQUEFIED''.
