This document provides information on IMO hazard class labels for dangerous goods transportation. It lists the nine hazard classes with their divisions and compatibility groups. It also shows examples of subsidiary risk labels that may be required in addition to the primary class label. Transport vehicles are required to display appropriate labels to identify hazards and facilitate safe handling.
