Question

When the transfer unit has been emptied but not cleaned or purged, what statement must be added to the shipping document if the transfer unit is to be driven to a new site without being cleaned or purged?

Answer 1

When transporting an emptied but not cleaned or purged transfer unit, the shipping document must contain a statement such as 'Residue: Last Contained [name of substance]' to comply with Hazardous Materials Regulations.

Step-by-step explanation:

When a transfer unit has been emptied but not cleaned or purged, there are specific regulations that must be followed for transportation due to potential residue and vapors that can pose a hazard. In the United States, according to the Department of Transportation (DOT), if the transfer unit is being moved without being cleaned or purged, the shipping documentation must include a statement that it contains residue of the last cargo transported. This is required by the Hazardous Materials Regulations (HMR). The exact wording of the statement can vary, but a common phrasing is 'Residue: Last Contained [name of substance].'

To comply with these regulations, the shipping document must accompany the transfer unit during transportation and be readily available to, and be reviewed by, any regulatory authorities upon request. This ensures safety measures are in place for the carrier, emergency responders, and the public
