Where can you find the hazard class(es) for HAZMAT being stored or transported?

The hazard class or classes for hazardous materials (HAZMAT) being stored or transported can be identified through a combination of sources that provide critical information about the nature of the materials. Vehicle placards offer a visual representation of the hazard class and are placed on the exterior of vehicles transporting hazardous materials. They serve to immediately inform emergency responders and the public of potential dangers associated with the cargo.

Additionally, the North American Emergency Response Guidebook (NALC Data Sheet) provides essential safety information associated with different hazardous materials. This resource includes guidance on how to respond to incidents involving these materials, clearly indicating their respective hazard classes.

While shipping papers and labels also contain important information regarding hazard classes, relying solely on these would not provide a complete understanding of the hazards involved in a transport situation. Therefore, it is crucial to use multiple sources, including vehicle placards and documentation like the NALC Data Sheet, to ensure comprehensive awareness of hazard classifications during transportation.
