What is a characteristic of 'numbers only' in hazardous materials packaging?

The characteristic of 'numbers only' in hazardous materials packaging is that it may apply to both bulk and non-bulk packagings. This aspect reflects the versatility and broad applicability of numerical identifiers in hazardous materials regulations. Using 'numbers only' allows for a clear and standardized way to identify and communicate dangerous goods, regardless of the packaging type.

In hazardous materials regulations, numerical designations often correspond to specific items in the Hazardous Materials Table, conveying critical information about the nature and hazards of the materials being transported. This numbering system enhances safety and recognition across different modes of transport, making it equally relevant for bulk containers, which hold larger quantities, as well as for non-bulk containers, which may hold smaller amounts.

This versatility in applicability is crucial for ensuring that handlers, transporters, and emergency responders can quickly and effectively identify hazardous materials to maintain safety protocols during transportation, storage, and emergencies.
