What should drivers follow when handling hazardous materials packages?

When handling hazardous materials packages, following orientation markings is crucial for ensuring safety during transport. Orientation markings indicate how a package should be positioned and handled to prevent accidents or spills. These markings typically include arrows or symbols that show the correct upright position of the package, which helps workers know how to handle and stack them appropriately. Improper positioning can lead to damage to the package, which might result in the release of hazardous materials.

While color-coded labels, manufacturer's guidelines, and standard operating procedures are also important aspects of handling hazardous materials, they serve different purposes. Color-coded labels provide information about the specific hazards associated with the materials, while manufacturer's guidelines offer instructions that may relate to product-specific handling requirements. Standard operating procedures are general protocols that guide the overall handling process. However, none of these are as critical in determining the safe orientation of a package as the orientation markings are. This makes orientation markings a primary focus for drivers handling hazardous material packages.
