Dear Ms. Olson:
This is in response to your letter dated February 9, 2001, requesting clarification of the placarding requirements for Division 1.1 and 1.2 materials transported by rail.
Specifically, you ask if it is necessary to placard the rail car . with EXPLOSIVE placards on a white square background in addition to the EXPLOSIVE placards already displayed on the bulk containers for transport by vessel and highway.
Section 172.510 requires that the specified placard for certain explosives be placed on a white square background (See § 172.527). If the placards affixed to the shipping containers are not displayed on a white square background the rail car must be placarded as specified in § 172.510. However, it is permissible to use the white square background for all modes of transportation. Therefore, if the shipping containers are initially placarded with the EXPLOSIVE placards on the white square background, no additional placarding is necessary.
I hope this satisfies your request.
