• An emergency response telephone number, which is monitored by a person who has knowledge of the hazmat, must be included with the shipping paper.

In most cases, an emergency response telephone number must be entered on the shipping paper. It can be immediately following the description of each hazardous material, or if the number applies to every hazardous material entered on the shipping paper, entered once on the shipping paper in a clearly visible location and identified as an emergency response information number.

The emergency response phone number must be monitored at all times that the hazardous material is in transportation, by a person who has knowledge of the hazardous material and has comprehensive emergency response and incident mitigation information for the material or has immediate access to such a person.

The emergency response telephone number must be:

• The number of the person offering the hazardous material for transport, when that person is also the emergency response information provider; or
• The number of an agency or organization (emergency response information telephone service provider) capable of and accepting responsibility for providing the response information. The person registered with the emergency response information telephone service must ensure that the service has the current information on the material before it is offered for transport.

When the person offering hazardous materials for transport is also the emergency response telephone information provider, that person’s name must be entered on the shipping paper near the emergency response telephone number. In addition, when the telephone number of an emergency response information (ERI) telephone service provider is used, the name of the person who is registered with the ERI service provider, or the contract number or other unique identifier assigned by the ERI provider, must be placed on the shipping paper near the emergency response telephone number. However, the above requirements do not apply if the name or identifier is entered elsewhere on the shipping paper in a prominent, readily identifiable, and clearly visible manner where it can be easily and quickly found.

The emergency response telephone number requirements do not apply to:

• Limited quantities;
• Materials described with the shipping names listed in 172.604(d)(2); or
• Vehicles or containers containing lading that has been fumigated and display the FUMIGANT marking, unless other hazardous material is present.
