2.10 Sources of Regulatory Information. Employees who identify hazardous materials for receipt,
storage, or packaging purposes must only use current reference documents and regulations. Annual
editions of the Code of Federal Regulations may be purchased from the United States Government
Printing Office (US GPO) and reprints are available from a number of private sources. The Code of
Federal Regulations is kept up to date by the individual issues of the Federal Register. These two
publications must be used together to determine the latest version of any given rule. Free label and
placard charts are available from DOT, which also include regulatory references. A particularly
useful chart, DOT Hazardous Material Warning Labels/Placards (DOT Chart 10), may be obtained
from the Department of Transportation, Research and Special Programs Administration, Washington,
DC 20590.
2.11 Retention of DOT Markings, Placards, and Labeling
A. Retain all required hazard markings, labels, and placards on hazardous material packagings until
the package is sufficiently cleaned of residue and purged of vapors to remove any potential hazards.
This requirement is specified in 29 CFR 1910.1201.
B. For non-bulk packages which will not be reshipped, the provisions are met if a label or other
acceptable
marking is affixed in accordance with the Hazard Communication Standard (29 CFR 1910.1200).
