What must be included if a gauge is transported in a vehicle?

When transporting a nuclear gauge, it is essential to include an Emergency Response Information Sheet. This sheet provides vital information that can assist emergency responders in the event of an incident, such as a leak or an accident during transport. It details the nature of the materials, appropriate safety measures, and instructions for handling any emergencies. Including this information is a regulatory requirement designed to ensure the safety of personnel and the public, emphasizing the importance of preparedness in potentially hazardous situations.

The other options, while relevant in certain contexts, do not specifically address the immediate need for emergency preparedness that the Emergency Response Information Sheet fulfills. For example, while a shipping log and invoices might track the gauge during transit and assist in logistical oversight, they do not equip emergency responders with the critical information they need in case of an accident. Similarly, the driver's license number does not provide relevant information about the materials being transported or how to handle an emergency involving those materials.
