Did you know that the Rail Roads have specific rules for DG placard and marking placement?

In order to ensure the safe transport of hazardous materials, it is necessary that hazardous placarding is visible at all times. If the placard is not placed in a prominent area on the sides or ends of the container, it is possible they will not be visible if that container is placed in the bottom of a double stack car. When a container is placed in the bottom position of a double stack car the bottom half and corners of the container are not visible. This could result in an improper or delayed response should an emergency arise.

In order to ensure visibility during the transportation of containers in double stack cars, all hazardous placards, UN/NA identification numbers, and/or markings must be displayed on containers as follows.
