How far must placards be from all other markings?

The requirement that placards must be placed at least 3 inches away from all other markings stems from the need for clear visibility and quick recognition of hazardous materials during transport. This distance helps to prevent confusion that could arise from overlapping symbols or text, ensuring that first responders, transport officials, and the general public can quickly identify the nature of the materials being transported. Adhering to this guideline enhances safety and ensures compliance with regulatory standards regarding the transport of hazardous materials. Such regulations are critical for minimizing risks during transit and responding effectively in emergency situations.
