This standard is a companion volume for IEEE Std 1512-2006, referred to here as the "Base Standard." This standard specifies messages, data frames, and data elements for communicating general and cargo information to other responders in support of real-time interagency transportation-related incident management. It addresses the unique disciplines associated with communications dealing with the control and confinement of hazardous materials during and after an incident. The Base Standard specifies messages, data frames, and data elements for the basic underlying communication involved in real-time interagency transportation-related incident management. Refer to the Base Standard for specification of the scope of the combination of the Base Standard and companion volumes such as this one. Together, the Base Standard and companion volumes shall be referred to as the "IEEE 1512 Family of Standards." Clause 5 and Clause 6 of this standard present the specified messages, data frames, and data elements in ASN.1 format and in XML formats.
