Subsidary Hazard Class and Number/Type of Packagings

This information collection is mandatory when a person offers a hazardous material with a subsidiary hazard into transportation and shipping papers are required. This is a reporting requirement on occasion when the hazardous materials with subsidiary classes are offered into transportation. Shipping papers identify the presence of hazardous materials that are being transported and assist carrier personnel and emergency responders in knowing the proper safety procedures and incident mitigation should an incident occur in transportation. The indication of a subsidiary hazard class further assists by reducing: (1) the need to sort through multiple entries on shipping papers to determine what hazardous materials are in a transport vehicle; and (2) delays in making proper determinations concerning the mitigation of an accident. Following review of this information collection, PHMSA has revised this burden based on more accurate stakeholder feedback.
